Background
With the development of communication technology, various portable electronic devices are widely used, such as tablet computers, smart phones, game machines, and portable multimedia players. However, when using current portable electronic devices, a user is often required to hold the electronic device with a hand and maintain a particular posture to operate the electronic device or view content displayed by the electronic device.

Detailed Description
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Note that in the present specification and the drawings, steps and elements having substantially the same structure are denoted by the same reference numerals, and repeated explanation of the steps and elements will be omitted.
Next, a head-mounted electronic apparatus according to an embodiment of the present invention will be described with reference to fig. 1. FIG. 1 shows an exemplary block diagram of a head mounted electronic device 100 according to one embodiment of the invention. As shown in fig. 1, the head-mounted electronic apparatus 100 includes a fixing unit 110, an image processing unit 120, an image transmission unit 130, a display unit 140, and an input unit 150.
The head-mounted electronic apparatus 100 can be worn on the head of the user through the fixing unit 110. For example, the fixing unit 110 may include wearing parts such as a helmet, a headband, and the like. Alternatively, the fixing unit 110 may also include a support arm that can be supported on the ear of the user.
The image processing unit 120 is provided in the fixing unit. The image processing unit 120 may obtain a first image to be displayed. For example, an image file may be stored in advance in the head mounted electronic apparatus 100. Obtaining the first image to be displayed 120 may obtain a stored image file and perform a play operation on the file to output the first image. For another example, the head-mounted electronic device 100 may further include a transmitting/receiving unit to receive an image file transmitted from another electronic device. Obtaining the first image to be displayed 120 may obtain a received image file and perform a play operation on the file to output the first image.
The image transmission unit 130 may transmit the first image to the display unit 140. And the display unit 140 may display the first image obtained by the image processing unit. The display unit 140 is connected to the fixing unit 110, and at least a first portion of the display unit 140 is located within a visual area of a user and faces the user when the display device is worn on the head of the user through the fixing unit.
The input unit 150 may be disposed on the fixing unit and/or the display unit, and detect a first position of the operating body with respect to the head-mounted electronic apparatus. The image processing unit 120 may generate a second image according to the first position detected by the input unit 150, and generate a third image according to the second image and the first image. Then, the display unit 140 may display the third image generated by the image processing unit 120.
According to an example of the present invention, the input unit 150 may include a sensing panel. The sensing panel can detect the operation body and obtain a second position of the operation body on the sensing panel as a first position of the operation body relative to the head-mounted electronic device 100.
For example, the second position may be a position of the operating body on the sensing panel when the operating body is in contact with the sensing panel. In this case, the display image processing unit 120 may generate the second image according to a position of the operating body on the sensing panel when the operating body is in contact with the sensing panel.
Optionally, the head-mounted electronic device 100 may further include a first instruction generating unit. The first instruction generating unit may determine whether contact of the operating body with the sensing panel satisfies a first generation condition according to a detection result of the sensing panel with respect to the operating body, and generate the first control instruction when it is determined that the first generation condition is satisfied. The image processing unit may generate a second image according to a position of the operating body on the sensing panel when the operating body is in contact with the sensing panel in response to the first control instruction. For example, the first generation condition may be a first time threshold. When the contact time of the operating body with a specific position on the sensing panel is greater than a first time threshold value according to the detection result of the sensing panel for the operating body, the first instruction generating unit can determine that a first generating condition is met and generate a first control instruction. The image processing unit can respond to the first control instruction and generate a second image according to the position of the current operating body on the sensing panel, which is in contact with the sensing panel.
For another example, the second position may include a position of a projection of the operating body on the sensing panel when a distance between the operating body and the sensing panel is less than or equal to a predetermined distance. In addition, optionally, the second position further includes a position of the operating body on the sensing panel when the distance between the operating body and the sensing panel is zero. In this case, the display image processing unit 120 may generate the second image according to a position of the manipulation body projected on the sensing panel when the distance between the manipulation body and the sensing panel is less than or equal to a predetermined distance and/or a position of the manipulation body on the sensing panel when the distance between the manipulation body and the sensing panel is zero.
Optionally, the head-mounted electronic device 100 may further include a second instruction generating unit. The second instruction generating unit may determine whether an operation body having a distance from the sensing panel less than or equal to a predetermined distance satisfies a second generation condition according to a detection result of the sensing panel for the operation body, and generate the second control instruction when it is determined that the second generation condition is satisfied. The image processing unit may generate the second image according to a position of the manipulation body projected on the sensing panel when the distance between the manipulation body and the sensing panel is less than or equal to a predetermined distance and/or a position of the manipulation body on the sensing panel when the distance between the manipulation body and the sensing panel is zero, in response to the second control instruction. For example, in a case where the second position includes a position of the operating body projected on the sensing panel when the distance between the operating body and the sensing panel is less than or equal to a predetermined distance, the second generation condition may be a first distance threshold between the operating body and the sensing panel, where the first distance threshold may be less than or equal to the predetermined distance. The second instruction generating unit may determine that a second generation condition is satisfied and generate a second control instruction when a distance between the operating body and the sensing panel gradually decreases to a first distance threshold according to a detection result of the sensing panel for the operating body. The image processing unit can respond to the second control instruction and generate a second image according to the position of the current operation body projected on the sensing panel. For another example, in the case where the second position includes a position of the operating body projected on the sensing panel when the distance between the operating body and the sensing panel is less than or equal to a predetermined distance and a position of the operating body on the sensing panel when the distance between the operating body and the sensing panel is zero generates the second image, the second generation condition may be that the distance between the operating body and the sensing panel gradually decreases, and a difference in distance between the position of the operating body projected on the sensing panel when the distance between the operating body and the sensing panel is less than or equal to the predetermined distance and the position of the operating body on the sensing panel when the distance between the operating body and the sensing panel is zero is less than or equal to a second distance threshold value. The second instruction generating unit may determine that a second generation condition is satisfied and generate a second control instruction when a distance between the operating body and the sensing panel is gradually decreased according to a detection result of the sensing panel for the operating body, and a distance difference between a position of the operating body projected on the sensing panel when the distance between the operating body and the sensing panel is less than or equal to a predetermined distance and a position of the operating body on the sensing panel when the distance between the operating body and the sensing panel is zero is less than or equal to a second distance threshold. The image processing unit may generate a second image according to a position of the operating body on the sensing panel when a distance between the operating body and the sensing panel is zero in response to the second control instruction.
According to another example of the present invention, the input unit 150 may include an image acquisition module and an image recognition module. Specifically, the image acquisition module may perform image acquisition on a spatial control area of the head-mounted electronic device 100 and obtain an acquisition result. The image recognition module determines a third position of the operating body in the spatial control region according to the acquisition result obtained by the image acquisition unit, as the first position of the operating body relative to the head-mounted electronic device 100. When the head-mounted electronic device 100 is worn on the head of the user, the user can view the first image obtained by the image processing unit displayed by the display unit 140 along a first direction, and the acquisition unit 150 acquires the spatial control region along a second direction, wherein an included angle between the first direction and the second direction is within a predetermined included angle range. For example, when the user performs a control operation in the spatial control region using an operation body such as a finger, the second direction of the operation body with respect to the head of the user is not parallel to the first direction of the first image displayed by the display unit 140 with respect to the user, so that the user does not need to lift the operation body up to its visible region to perform an operation on the head-mounted electronic device, that is, the user may not see the operation body when the operation is in the spatial control region.
Optionally, the head-mounted electronic device 100 may further include a third instruction generating unit. The third instruction generating unit may determine whether the operation body in the spatial control region satisfies a third generation condition according to the acquisition result, and generate a third control instruction according to which the image processing unit generates the second image when it is determined that the third generation condition is satisfied. For example, the third generation condition may be a second time threshold. When the image recognition module determines that the time of the operator held at a specific position in the spatial control region is greater than the second time threshold value according to the acquisition result obtained by the image acquisition unit, the third instruction generation unit may determine that a third generation condition is satisfied, and generate a third control instruction. The image processing unit 120 may generate the second image according to the position of the current operator in the spatial control region in response to the third control instruction.
Further, according to still another example of the present invention, the input unit 150 may include a plurality of input regions. The input unit 150 may detect the operation body to determine a target input region corresponding to the operation body among the plurality of input regions, and detect an operation of the operation body in the target input region to obtain the first position according to the operation of the operation body in the target input region.
For example, the input unit 150 may be a touch input unit and include a plurality of sequentially arranged touch input regions. When the operation body is in contact with the touch input unit, the input unit 150 may determine, among the plurality of touch input areas, a target touch input area to which a touch position of the operation body when in contact with the touch input unit belongs, and further detect an operation of the operation body in the target touch input area to obtain the first position according to an operation of the operation body in the target touch input area, such as a long-time touch held at a specific position, a left movement, a right movement, a forward movement, a backward movement, and the like.
Fig. 2 is an explanatory diagram showing a schematic case of input by an input unit according to still another example of the present invention. In the example shown in fig. 2, the input unit 150 is a touch input unit, and includes three sequentially arranged touch input regions 210, 220, and 230. As shown in fig. 2, the touch input regions 210, 220, and 230 correspond to character regions 240, 250, and 260, respectively. The characters contained in the character areas 240, 250, and 260 are different from each other. Each character area contains a first character located at the center of the character area, and a plurality of second characters arranged around the first character. As shown in fig. 2, the first character of the character area 240 is S, the first character of the character area 250 is G, and the first character of the character area 260 is K. When a finger of a user as an operation body is in contact with the touch input area 220 and moves rightward in the direction indicated by the arrow in the touch input area 220, the input unit 150 determines the touch input area 220 as a target touch input area in the touch input areas 210, 220, and 230, and obtains that the operation body moves rightward in the direction indicated by the arrow in the target touch input area 220 to the first position a. The image processing unit may determine the character region 250 corresponding to the target touch input region 220 as a target character region among the character regions 240, 250, and 260 according to the target input region 220, determine a second character H positioned at the right side of the first character G as a first target character in the target character region according to the movement locus and the first position a of the operator, and generate a second image with respect to the first target character H. According to the present example, since the number of input regions is small, and a structure such as a projection can be provided in the input region, the user can recognize each touch region easily even without seeing it and input quickly.
It should be noted that in the example shown in fig. 2, the description has been made taking the example in which the input unit 150 is a touch input unit, but the present invention is not limited thereto, and for example, as described above, the input unit 150 may also be a proximity sensing unit or an image capturing unit or the like that does not require an operating body to contact therewith. The number of input regions is not limited to 3, and the input unit 150 may include 2 touch regions or 4 or more input regions. And the input regions may be respectively provided at portions of the fixing unit or the display unit near left and right sides of the user's head when the head-mounted electronic apparatus 100 is worn on the user's head.
According to the head-mounted electronic equipment provided by the embodiment of the invention, when a user wears the head-mounted electronic equipment, the user does not need external input equipment such as a mouse and a keyboard, and only the head-mounted electronic equipment can realize complex input, so that the constraint of the external input equipment on the user is eliminated, and the head-mounted electronic equipment is convenient for the user to carry and use under the condition of movement.
Further, according to an example of the present invention, the image processing unit 120 of the head-mounted electronic device 100 may further obtain a mapping position of the first position with respect to the first image before generating the second image, and when it is determined that the mapping position is located in the first image, generate a mapping flag indicating the mapping position in the first image to help the user determine the position of the operation body by viewing the first image including the mapping flag, avoiding erroneous input.
For example, a keyboard region including a plurality of third characters may be included in the first image. The image processing unit 120 may determine a mapping position of the first position obtained from the input unit with respect to the first image, and generate a mapping flag indicating the mapping position in the first image when it is determined that the mapping position is located in the first image. The user can know the third character in the keyboard area corresponding to the current first position through the displayed mapping identification, so that the user can adjust the first position of the operator relative to the head-mounted electronic equipment according to the displayed mapping identification so as to select the desired character in the keyboard area.
Specifically, after generating the map flag indicating the map position in the first image, the input unit 150 may further receive a character input operation from the operator (e.g., the input operation for generating the first instruction, the second instruction, and the third instruction described above), and the image processing unit may determine a second target character corresponding to the map flag among the plurality of third characters according to the character input operation and generate a second image regarding the second target character.
According to another example of the present invention, the image transmission unit 130 of fig. 1 may include a data transmission line provided in the fixing unit 110. The data transmission line may transmit the first image to the display unit 140. Fig. 3 is an exemplary block diagram illustrating a display unit according to one example of the present invention. As shown in fig. 3, the display unit 300 may include a first display module 310, a first optical system 320, a first light guide member 330, a second light guide member 340, a frame member 350, and a lens member 360. Fig. 4 is an explanatory diagram showing one schematic situation of the display unit 300 shown in fig. 3.
The first display module 310 may be disposed in the frame member 350 and connected with the first data transmission line. The first display module 310 can display a first image according to the first video signal transmitted by the first data transmission line. According to an example of the present invention, the first display module 310 may be a display module of a micro display screen having a small size.
The first optical system 320 may also be provided in the frame member 350. The first optical system 320 may receive light emitted from the first display module and perform optical path conversion on the light emitted from the first display module to form a first enlarged virtual image. That is, the first optical system 320 has a positive refractive power. So that the user can clearly view the first image and the size of the image viewed by the user is not limited by the size of the display unit. For example, the optical system may include a convex lens. Alternatively, the optical system may also form a lens assembly from a plurality of lenses including convex and concave lenses in order to reduce aberrations, avoid interference with imaging by chromatic dispersion, etc., resulting in a better visual experience for the user.
As shown in fig. 4, after the first optical system 320 receives the light emitted from the first display module 310 and performs optical path conversion on the light emitted from the first display module 310, the first light guide part 330 may transmit the light passing through the first optical system to the second light guide part 340. The second light guide member 340 may be disposed in the lens member 360. And the second light guide member may receive the light transmitted through the first light guide member 330 and reflect the light transmitted by the first light guide member 330 toward the eyes of the user wearing the head-mounted electronic device.
Fig. 5 is an explanatory diagram showing one example situation of the head mounted electronic apparatus shown in fig. 1. The head-mounted electronic device 500 is a glasses-type electronic device. The head-mounted electronic device 500 includes a fixing unit, an image processing unit, an image transmission unit, and an input unit similar to the fixing unit 110, the image processing unit 120, the image transmission unit 130, the display unit 140, and the input unit 150 in the head-mounted electronic device 100, and a display unit similar to the display unit in the electronic device 100 and described in conjunction with fig. 3, and thus, a detailed description thereof is omitted.
As shown in fig. 5, the fixing unit of the head-mounted electronic device 500 includes a first support arm 510, a second support arm 520, and a third holding portion (not shown). Specifically, the first support arm 510 includes a first connecting portion and a first holding portion (shown in phantom in the first support arm 510), wherein the first connecting portion is configured to connect the frame member and the first holding portion. The second support arm 520 includes a second connecting portion configured to connect the frame member and a second retaining portion (shown in phantom in the first support arm 520). Similar to the display unit described above in connection with fig. 3, the display unit of the head mounted electronic device 500 includes a frame member 530 and a lens member 540 connected to the frame member 530. The third holding part of the fixing unit is provided on the frame member 530. In particular, the third retaining portion may be provided at a location on the frame member 530 between the two lens members. The head-mounted electronic device is held on the head of the user by the first holding portion, the second holding portion, and the third holding portion. Specifically, the first and second retaining portions may be used to support the first and second support arms 510, 520 at the user's ears, while the third retaining portion may be used to support the frame member 530 at the user's nose bridge.
The input unit of the head mounted electronic device 500 may be disposed on the first support arm 510, the second support arm 520, and/or the frame member 530. For example, when the input unit includes a sensing panel, the input unit may be disposed on the first support arm 510 and/or the second support arm 520 to facilitate an input operation such as a touch or proximity by a user. And when the input unit includes an image pickup module, the image pickup module in the input unit may be provided on the frame member 530 so as to pick up the manipulation body in the space control region.
Further, as shown in fig. 5, according to one example of the present invention, the frame member 530 may include a first stub portion 531 connected to the first support arm and a first stub portion 532 connected to the second support arm (as shown in the circle of fig. 5). The first display module and the first optical system comprised by the display unit may be arranged in the first stub head part 531 and/or the first stub head part 532.
Furthermore, according to another example of the present invention, the head mounted electronic device shown in fig. 5 may further include an audio processing unit and a bone conduction unit. The audio processing unit may perform audio processing and output a first audio signal. For example, an audio file may be stored in the head mounted electronic device 500 in advance. The audio processing unit may obtain a stored audio file and perform a play operation on the file to output a first audio signal. For another example, the head-mounted electronic device 500 may further include a transmitting/receiving unit to receive an audio file transmitted from another electronic device. The audio processing unit may obtain the received audio file and perform a play operation on the file to output a first audio signal. Preferably, the audio processing unit is disposed in the first retaining portion of the first support arm 510 and/or the first retaining portion of the second support arm 520. Further, preferably, the bone conduction unit may be disposed inside the first connection portion of the first support arm 510 and/or inside the second connection portion of the second support arm 520, and generate vibration according to the first audio signal. In an example of the present invention, the inner sides of the first and second connection portions are sides of the first and second connection portions that are close to the head of the user when the head-mounted electronic device is worn on the head of the user. The bone conduction unit may generate vibration according to the audio signal from the audio processing unit so that the user can listen to audio through the generated vibration. Specifically, when the head mounted electronic device 500 is worn on the head of the user, the bone conduction unit is in contact with the head of the user, so that the user can perceive the vibration generated by the bone conduction unit.
According to an example of the present invention, the bone conduction unit may directly receive the audio signal from the audio processing unit and generate vibration according to the audio signal. Alternatively, according to another example of the present invention, the head-mounted electronic device 500 may further include a power amplifying unit provided in the fixing unit. The power amplifying unit can receive the audio signal from the audio processing unit and amplify the audio signal, wherein the amplified audio signal is an alternating voltage signal.

By providing the bone conduction unit in the head mounted electronic apparatus, a user can listen to audio by using the inner side bone conduction unit provided in the head mounted electronic apparatus, improving audio output quality. Further, since it is not necessary to provide a conventional audio playing unit such as a speaker, an earphone, or the like in the head mounted electronic apparatus, the content listened to by the user is prevented from being known to others while reducing the space occupied by the head mounted electronic apparatus.
Further, preferably, in the first and/or second support arm, a protective layer of the bone conduction unit that is in contact with the head of the user, a body of the first bone conduction unit, a data transmission unit layer (which may include a data transmission line, for example), and an input unit layer may be sequentially disposed in order from an inner side of the support arm (i.e., a side close to the head of the user when the head-mounted electronic device is worn on the head of the user) to an outer side of the support arm (i.e., a side away from the head of the user when the head-mounted electronic device is worn on the head of the user). In addition, in the case that the input unit includes the above-described sensing panel, the input unit layer may include a sensing panel layer and a protective layer of the sensing panel layer, and in addition, a spacer layer may be further disposed between the data transmission unit layer and the sensing panel layer to prevent interference of an electric signal in the data transmission unit layer with the sensing panel layer. Through this structure, rationally set up bone conduction unit and the position of input unit on head-mounted electronic equipment, optimized head-mounted electronic equipment's product appearance design when having improved audio output quality to user's use and then operation has been made things convenient for.

Next, an input method of an embodiment of the present invention is explained with reference to fig. 7. FIG. 7 is a flow chart depicting an input method 700 according to an embodiment of the invention. The input method 700 may be applied to the head mounted electronic devices shown in fig. 1 to 6. The head-mounted electronic device according to the embodiment of the present invention has been described in detail above with reference to fig. 1 to 6. Therefore, for brevity of description, no further description is provided.
As shown in fig. 7, in step S701, a first image is displayed. For example, an image file may be stored in advance in the head-mounted electronic device. The first image 120 to be displayed may be obtained in step S701, a stored image file may be obtained, and a play operation is performed on the file to display the first image. For another example, the head-mounted electronic device may further include a transmitting/receiving unit to receive an image file transmitted from another electronic device. The received image file may be obtained and a play operation may be performed on the file to display the first image in step S701.
In step S702, a first position of an operator with respect to the head-mounted electronic device may be detected. Then in step S703, a second image is generated from the first position detected in step S702, and a third image is generated from the second image and the first image. Finally, the generated third image may be displayed in step S704.
Optionally, before step S703, the method shown in fig. 7 may further include obtaining a mapping position of the first position with respect to the first image, determining whether the mapping position is located in the first image, and generating a mapping identifier indicating the mapping position in the first image when the mapping position is determined to be located in the first image. Thereby helping the user to determine the position of the operator by viewing the first image including the mapping identifier, avoiding erroneous input.
Further, according to an example of the present invention, a plurality of third characters may be included in the first image. After generating the mapping identifier indicating the mapping position in the first image, the input method 700 shown in fig. 7 may further include receiving a character input operation from the operator. And in step S703, a second target character corresponding to the mapping identifier is determined among the plurality of third characters according to the character input operation, and then a second image regarding the second target character is generated.
Fig. 8a to 8c are explanatory views showing one schematic case of generating a mapping flag indicating a mapping position by generating a mapping flag according to the present invention, and generating a second image of a second target character corresponding to the mapping flag. In the example shown in fig. 8 a-8 c, the head mounted electronic device includes a sensing panel 810. According to step S701, a first image is displayed. As shown in fig. 8a, a keyboard region including a plurality of third characters may be included in the first image 810.
As shown in fig. 8b, according to step S702, the operation body is detected, and the position of the operation body on the sensing panel 820 when the operation body is in contact with the sensing panel is obtained as the first position of the operation body relative to the head-mounted electronic device. Then, as described above, a mapped position of the first position with respect to the first image is obtained, and a mapped mark indicating the mapped position is generated in the first image (as shown by the finger mark 830 in fig. 8 c).
In the example shown in fig. 8a to 8c, when a character input operation from the operator is received, as described above, in step S703, a second target character corresponding to the mapping identification is determined among the plurality of third characters according to the character input operation, and then a second image regarding the second target character is generated. Specifically, when the contact of the operation body with the sensing panel 820 is detected, in step S703, it may be determined whether the contact of the operation body with the sensing panel 820 satisfies the first generation condition. For example, the first generation condition may be a first time threshold. When the detection result of the sensing panel 820 for the operation body indicates that the contact time of the operation body with a specific position on the sensing panel is greater than the first time threshold, it may be determined in step S703 that the first generation condition is satisfied, and it may be further determined that the current input operation of the operation body is a character input operation, and a first control instruction is generated in response to the character input operation, and then a second image is generated based on the position of the current operation body on the sensing panel according to the first control instruction.
Fig. 9a to 9e are explanatory views showing another schematic case of generating a mapping flag indicating a mapping position by generating a mapping flag according to the present invention, and generating a second image of a second target character corresponding to the mapping flag. In the example shown in fig. 9 a-9 e, the head mounted electronic device includes a sensing panel 920. According to step S701, a first image is displayed. As shown in fig. 9a, a keyboard region including a plurality of third characters may be included in the first image 910.
Then, according to step S702, the operation body is detected, and a position b (shown in fig. 9 b) of the operation body projected on the sensing panel when the distance between the operation body and the sensing panel 920 is less than or equal to the predetermined distance and/or a position of the operation body on the sensing panel when the distance between the operation body and the sensing panel is zero is obtained as the first position of the operation body relative to the head-mounted electronic device. Then, as described above, a mapped position of the first position with respect to the first image is obtained, and a mapped mark indicating the mapped position is generated in the first image (as shown by the finger mark 930 in fig. 9 c).
In the example shown in fig. 9a to 9e, when it is detected that the distance between the operating body and the sensing panel 920 is less than or equal to the predetermined distance H1, as described above, in step S703, a second target character corresponding to the mapping identifier is determined among the plurality of third characters according to the character input operation, and then a second image regarding the second target character is generated. For example, in the example shown in fig. 9d, when it is detected that the distance between the operating body and the sensing panel 920 is less than or equal to the predetermined distance H1, in step S703, it may be determined whether the second generation condition is satisfied by the operating body having the distance from the sensing panel that is less than or equal to the predetermined distance. The second generation condition may be a first distance threshold H2 between the operating body and the sensing panel, wherein the first distance threshold may be less than or equal to the predetermined distance. When the detection result of the sensing panel 920 for the operation body indicates that the distance between the operation body and the sensing panel gradually decreases to the first distance threshold H2, in step S703, it may be determined that the second generation condition is satisfied, and a second control instruction is generated, and in response to the second control instruction, a second image is generated according to the position of the current operation body projected on the sensing panel. For another example, the second generation condition may be that the distance between the operating body and the sensing panel gradually decreases, and the difference in distance between the position of the operating body projected on the sensing panel when the distance between the operating body and the sensing panel is less than or equal to a predetermined distance and the position of the operating body on the sensing panel when the distance between the operating body and the sensing panel is zero is less than or equal to a second distance threshold. As shown in fig. 9e, when the detection result of the sensing panel for the operation body indicates that the distance between the operation body and the sensing panel gradually decreases, and the distance difference between the position of the operation body projected on the sensing panel when the distance between the operation body and the sensing panel is less than or equal to the predetermined distance and the position of the operation body on the sensing panel when the distance between the operation body and the sensing panel is zero is less than or equal to the second distance threshold, in step S703, it may be determined that the second generation condition is satisfied, and a second control instruction is generated, and in response to the second control instruction, a second image is generated according to the position of the operation body on the sensing panel when the distance between the operation body and the sensing panel is zero.
Fig. 10a to 10c are explanatory diagrams showing one schematic case of generating a mapping flag indicating a mapping position by the present invention, and generating a second image of a second target character corresponding to the mapping flag. In the example shown in fig. 10a to 10c, the head mounted electronic device comprises an image acquisition module. According to step S701, a first image is displayed.

Then, as described above, a mapped position of the first position with respect to the first image is obtained, and a mapped mark indicating the mapped position is generated in the first image (as shown by the finger mark 1030 in fig. 10 c).
In the example shown in fig. 10a to 10c, when a character input operation from the operator is received, as described above, in step S703, a second target character corresponding to the mapping identification is determined among the plurality of third characters according to the character input operation, and then a second image regarding the second target character is generated. Specifically, when it is determined from the acquisition result that the operating body is located in the spatial control region 1020, in step S703, it may be determined whether the operating body in the spatial control region 1020 satisfies the third generation condition. For example, the third generation condition may be a second time threshold. When the detection result of the sensing panel 820 for the operation body indicates that the held time of the operation body at a specific position in the spatial control region 1020 is greater than the second time threshold, it may be determined in step S703 that the third generation condition is satisfied, and it may be further determined that the current input operation of the operation body is a character input operation, and a third control instruction is generated in response to the character input operation, and then a second image is generated according to the third control instruction based on the position of the current operation body in the spatial control region.

In this case, in step S702, an image of the spatial control area of the head-mounted electronic device may be acquired by the image acquisition module, and an acquisition result is obtained; and determining a third position of the operating body in the space control area according to the acquisition result as the first position of the operating body relative to the head-mounted electronic equipment.
Preferably, the plurality of input regions may correspond to a plurality of character regions, wherein characters contained in the plurality of character regions are different from each other. Each character area contains a first character located at the center of the character area, and a plurality of second characters arranged around the first character. In step S703, a target character region may be determined among the plurality of character regions according to the target input region; and determining a first target character in the target character region according to the first position, and generating a second image regarding the first target character. According to the present example, since the number of input regions is small, and a structure such as a projection can be provided in the input region, the user can recognize each touch region easily even without seeing it and input quickly.
According to the control method of the above embodiment of the present invention, when the user wears the head-mounted electronic device, the user can implement complex input only by using the head-mounted electronic device itself without using an external input device such as a mouse, a keyboard, or the like, so as to get rid of the constraint of the external input device on the user, and the user can conveniently carry and use the head-mounted electronic device under the condition of movement.
