Description

Gesture track update method and system for hand-held touch device

technical field

The present invention relates to a gesture track input method and system for a hand-held touch device, in particular to a gesture track update method and system for a hand-held touch device capable of correcting the gesture track at any time. the

Background technique

In the prior art, the hand-held touch device 10 already uses the touch module 11 to detect the touched part to form the gesture track 12, and executes the corresponding control command according to the gesture track 12. the

As shown in FIG. 1A , when editing text and graphics, a finger or a stylus is on the touch module 11 and slides upward to generate a straight upward gesture track 12 , and the hand-held touch device 10 turns pages up. the

As shown in FIG. 1B , when browsing a webpage, the finger slides clockwise on the touch module 11 to generate a clockwise and arc-shaped gesture trajectory 12, and the hand-held touch device 10 returns to the previous browsed webpage according to the arc-shaped gesture trajectory 12. or the finger slides counterclockwise on the touch module 11 to generate a counterclockwise, arc-shaped gesture trajectory 12, and the handheld touch device 10 proceeds to the next webpage browsing according to the arc-shaped gesture trajectory 12. the

However, the previous technology has an unavoidable defect, that is, when the user consciously draws a wrong gesture trajectory, he cannot immediately correct the gesture trajectory when the finger stays on the touch module. The user needs to leave the touch module to execute the control command corresponding to the wrong gesture trajectory, and then cancel the execution action of the control command, or activate the related function to return the handheld touch device to the operating state before executing the control command, thereby increasing unnecessary use Time and practicality are subject to discussion. the

Second, if the control order cannot be canceled once it is executed, it is very likely to cause unnecessary losses to the user or his company. For example, when the user edits the email of an important customer, he wants to clear the content of the wrong email, but sends the wrong control command and sends the wrong email. Sending out mails will cause unnecessary misunderstandings for customers due to wrong mails. What's more, it is very likely that the company's confidential documents and personal privacy will be leaked, thereby damaging the reputation of the company and individuals. the

It can be seen that the above-mentioned existing hand-held touch devices obviously still have inconveniences and defects in terms of method, product structure and use, and need to be further improved urgently. In order to solve the above-mentioned existing problems, relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and there is no suitable method and structure for general methods and products to solve the above-mentioned problems.

Detailed ways

In order to further explain the technical means and effects adopted by the present invention to achieve the intended purpose of the invention, the specific implementation of the gesture track updating method and system of the hand-held touch device according to the present invention will be described below in conjunction with the accompanying drawings and preferred embodiments Ways, methods, steps, structures, features and effects thereof are described in detail below. the

Please refer to FIG. 2 , which is a first block diagram of a handheld touch device according to an embodiment of the present invention. The handheld touch device 100 a includes a storage module 106 , a touch module 110 and a control unit 105 . the

The storage module 106 stores more than one track path 111 , and the control unit 105 is electrically coupled to the touch control module 110 and the storage module 106 respectively. The touch module 106 is used for the user to touch the touch module 106 with a finger, a stylus and other related objects, and record the touched position to continuously form a gesture track 120 . the

The control unit 105 obtains the gesture trajectory 120 recorded by the touch module 110, matches the gesture trajectory 120 with the trajectory paths pre-stored in the storage module 106, and determines whether it matches at least one of all the trajectory paths. If it is judged to be consistent, the control unit does not act, so that the touch module 110 keeps updating the gesture track 120 . If it is determined not to match, the control unit 105 clears the gesture track 120 recorded by the touch module 110 . the

In addition, the touch module 110 can be a touch screen to display the recorded gesture trajectory 120 . Moreover, the control unit 105 can make the touch module 110 display the trajectory path 111 corresponding to the gesture trajectory 120 for the user to know the command corresponding to the gesture trajectory currently input. Furthermore, when the control unit 105 determines that the touch module 110 is being touched, the control unit 105 can make the touch module 110 display all the trajectory paths 111 pre-stored in the storage module 106 for user's reference. the

Please refer to FIG. 3A , which is a schematic diagram of holding the handheld touch device 100 a in all embodiments of the present invention, and please refer to FIG. 2 for easy understanding. As can be seen from FIG. 3A , the user can hold the handheld touch device 100 a with one hand, and use the thumb to touch and slide the touch module 110 of the handheld touch device 100 a to draw a desired gesture trajectory 120 . In the meantime, all actions of the user can be completed with one hand. Of course, the user can also hold the handheld touch device 100a with one hand, touch and slide the touch module 110 with the other hand to draw the gesture track 120 . the

Please refer to FIG. 3B , which is a schematic diagram of the update flow of the gesture track 120 according to the first embodiment of the present invention. The method includes the following steps:

Record the touched position of a touch module 110 of the hand-held touch device 100a to continuously form a gesture track 120 (step S110 ). As shown in FIG. 3C , when the touch module 110 of the hand-held touch device 100a is touched by the user's finger, the first touched position is shown as the starting point 121, and the current position still touched by the finger is shown as end point 122 , and record all parts of the touch module 110 that are continuously touched between the start point 121 and the end point 122 to form a continuous gesture trajectory 120 . The gesture track 120 is displayed on the touch module 110 and is presented as a line with a specific width. the

Match the gesture trajectory 120 with the plurality of trajectory paths 111 pre-stored in the handheld touch device 100a (step S120). As shown in FIG. 3D, it is all the trajectory paths 111 pre-stored in the handheld touch device 100a. The directions of these trajectory paths 111 are: up, down, left, right, up-left, up-right, down-left , Down-Right, Left-Up, Left-Down, Right-Up, Right-Down, etc., but not limited to these, it can also be left diagonally up, left diagonally down, right diagonally up and right diagonally down, etc. . Since these trajectory paths 111 are applied to the handheld touch device 100a, the lines used for comparison are kept simple, and the operator can pre-store the required trajectory paths 111 according to different functions. In addition to the above-mentioned directions, the track path 111 can be additionally designed in a clockwise direction and a counterclockwise direction. the

As shown in Figure 3C, when the user slides on the touch module 110, the direction of the drawn gesture track 120 is down-left, and the control unit 105 forms Conditions such as lines are compared with the directions of all trajectory paths 111 . Therefore, when the gesture track 120 is "down", the control unit 105 compares and finds that the matching track path 111 includes: down, down-left, and down-right. When the gesture trajectory 120 turns to "left", the control unit 105 compares and finds that the matching trajectory path 111 is the bottom left. To ensure that the user correctly inputs the gesture track 120 , the control unit 105 can display the track path 111 matched by the gesture track 120 on the touch module 110 . the

Alternatively, as shown in FIG. 3E , the touch module 110 can be a touch screen. When the control unit 105 judges that the touch module 110 is touched, it will make the touch module 110 display all the trajectory paths for the user. refer to. the

Determine whether the gesture track 120 matches at least one of the track paths 111 (step S130 ), and the control unit 105 determines whether the gesture track 120 input by the user is a gesture track 120 suitable for the handheld touch device 100a. the

If it is judged to be consistent, the control unit 105 makes the touch module 110 retain the previously recorded touched position to continuously update the gesture track 120 (step S132 ), as shown in FIG. 3C . the

If it is determined that it does not match, the gesture track 120 is cleared (step S131). That is, as shown in FIG. 4A , the gesture trajectory 120 drawn by the user does not conform to the trajectory path 111, and the control unit 105, as shown in FIG. The touch position is used as the starting point 121 of the gesture track 120 to continuously draw the gesture track 120 . the

After that, the control unit 105 determines whether the touch module 110 is still touched (step S140 ). If it is determined that the touch module 110 is still being touched, then return to step S120 to continuously match the gesture trajectory 120 and the trajectory path 111 . On the contrary, if it is determined that the touch module 110 is not touched, it means that the user's finger leaves the touch module 110 and the currently recorded gesture trajectory 120 is required. The control unit 105 records the gesture track 120 as a stop track, compares the stop track with all the track paths 111, and obtains the track path 111 matching the stop track (step S150). the

In addition, the handheld touch device 100a can execute a related control command according to the track path 111 matching the stop track. For example, the function of scrolling pages up and down in a document editing program, the function of turning pages forward and backward in a web browser, and the functions of playing, recording, and selecting songs in a media player. Another example is the built-in system function modules of the operating system in the handheld touch device 100a, such as login, shutdown, or preset shortcut commands. the

Please refer to FIG. 5 , which is a second block diagram of a handheld touch device according to an embodiment of the present invention. The handheld touch device 100 b includes a storage module 106 , a touch module 110 and a control unit 105 . The storage module 106 stores a trajectory elimination rule 107 , and the control unit 105 is electrically coupled to the touch control module 110 and the storage module 106 respectively. the

The touch module 106 is used for the user to touch the touch module 106 with a finger, a stylus and other related objects, and record the touched position to continuously form a gesture track 120 . the

The control unit 105 obtains the gesture trajectory 120 recorded by the touch module 110 , and determines whether the formation of the gesture trajectory 120 conforms to the trajectory elimination rule 107 . If it is determined not to match, the control unit 105 does not act, so that the touch module 110 keeps updating the gesture track 120 . If it is judged to be consistent, the gesture trajectory 120 is cleared according to the trajectory elimination rule 107 , and an error is corrected between the currently touched part of the touch module 110 and the end point of the gesture trajectory 120 . the

In addition, the touch module 110 can be a touch screen to display the recorded gesture trajectory 120 . Moreover, the storage module 106 can pre-store a plurality of trajectory paths 111 , and the control unit 105 can make the touch module 110 display the trajectory paths 111 corresponding to the gesture trajectory 120 , so that the user can know the command corresponding to the currently input gesture trajectory. Furthermore, when the control unit 105 determines that the touch module 110 is being touched, the control unit 105 can make the touch module 110 display all the trajectory paths 111 pre-stored in the storage module 106 for user's reference. the

The trajectory elimination rule 107 includes three judgment modes: 1. Let a range of a specific width on both sides of the vertical gesture trajectory 120 be an error zone of the gesture trajectory 120, and the control unit 105 judges that when the error zone adjacent to the end point of the gesture trajectory 120 is touched , the formation of the gesture trajectory 120 conforms to the trajectory elimination rule 107, and the control unit 105 promptly analyzes the touched part of the error zone to calculate the local trajectory that should be eliminated; , the formation of the gesture trajectory 120 meets the trajectory elimination rule 107, and the control unit 105 makes the overlapping portion to the end point of the gesture trajectory 120 to be a local trajectory, and the overlapping portion is set to be the end point after the gesture trajectory 120 eliminates the local trajectory; three, the gesture trajectory When the end point of 120 overlaps with the gesture trajectory, the formation of the gesture trajectory 120 conforms to the trajectory elimination rule 107, and the control unit 105 eliminates the overlapping trajectory of the gesture trajectory 120, and sets the end point of the gesture trajectory 120 after the overlapping trajectory is eliminated. the

Please refer to FIG. 6A, which is a schematic diagram of the gesture update process of the second embodiment of the present invention. Please also refer to FIG. 5, FIG. 6B to FIG. 6L for better understanding. FIG. The flow chart of the elimination rule, Fig. 6C is a drawing diagram of the gesture trajectory of the second embodiment of the present invention, Fig. 6D is a schematic diagram of the touch in the error area of the second embodiment of the present invention, Fig. 6E is the partial trajectory elimination of the second embodiment of the present invention Schematic diagram, FIG. 6F is a flowchart of the second trajectory elimination rule in the second embodiment of the present invention, FIG. 6G is a schematic diagram of trajectory overlap in the second embodiment of the present invention, and FIG. 6H is a schematic diagram of partial trajectory elimination in the second embodiment of the present invention. Fig. 6I is a flow chart of gesture track updating in the third embodiment of the present invention; Fig. 6J is a drawing diagram of gesture track in the third embodiment of the present invention; Fig. 6K is a schematic diagram of track overlapping in the third embodiment of the present invention; Schematic diagram of local track elimination in the third embodiment of the invention. The gesture update method includes the following steps:

First record the touched position of a touch module 110 of the hand-held touch device 100b, so as to continuously form a gesture track 120 (step S210). This is the same as step S110, and will not be repeated here. the

Next, the control unit 105 determines whether the formation of the gesture track 120 complies with a track elimination rule 107 (step S220 ). The trajectory elimination rule 107 has three, as follows:

The flow of the first method is shown in FIG. 6B , and the direction of the gesture track 120 is the same as the following - left as an example: first set an error area 130 of the gesture track 120, and the error area 130 is a specific width on both sides of the vertical gesture track 120 range (step S310). the

That is, as shown in FIG. 6C , when the gesture track 120 continues to be generated, the control unit 105 keeps centering on the gesture track 120 and sets an error zone 130 with a wide range on the same side. the

Next, determine whether the error zone 130 adjacent to the end point 122 of the gesture track 120 is touched (step S320). In this example, the control unit 105 mainly determines whether the user wants to correct the gesture track 120 based on the condition that the error area 130 of the end point 122 is touched. the

If it is determined that the error area 130 around the end point 122 is touched, that is, it is determined that the formation of the gesture trajectory 120 conforms to the trajectory elimination rule 107 (step S321), the control unit 105 immediately analyzes the touched position of the error area 130 to calculate the gesture trajectory 120 should be The eliminated local trajectory 123 (step S322). The location of the partial trajectory 123 is shown in FIG. 6D. the

That is, as shown in Figure 6E, the finger slides backwards from the end point 122 of the gesture trajectory 120 according to the formed gesture trajectory 120, and the generated reverse trajectory is located in the error area 130, and the control unit 105 calculates the touched error area 130, and deduces them one by one. Local trajectories 123 that should be eliminated. the

If it is determined that the error area 130 around the end point 122 is not touched, that is, it is determined that the formation of the gesture trajectory 120 does not conform to the trajectory elimination rule 107 (step S323 ), the control unit 105 does not perform any action. the

The flow of the second method is shown in FIG. 6F . The control unit 105 first determines whether the end point 122 of the gesture track 120 overlaps any part of the gesture track 120 (step S330 ). the

If it is determined to be overlapping, it is determined that the formation of the gesture track 120 conforms to the track elimination rule 107 (step S331 ). That is, as shown in FIG. 6G , the end point 122 of the gesture trajectory 120 is located and overlapped on its own vertical line segment, and this type of gesture trajectory 120 must not conform to the trajectory path 111 pre-stored in the storage module 106 . As shown in FIG. 6H , the control unit 105 makes the partial trajectory 123 between the overlapping portion and the end point 122 of the gesture trajectory 120 (step S332), and then sets the overlapping portion as the end point 122 after the partial trajectory 123 is eliminated from the gesture trajectory 120 (step S333 ). On the contrary, that is, it is determined that the formation of the gesture trajectory 120 does not comply with the trajectory elimination rule 107 (step S334), and the control unit 105 does not perform any action. the

The flow of the third method is shown in FIG. 6I and FIG. 6J. The touch module 110 will record the touched part to continuously form a gesture track 120 with a specific width. The end point 122 of the gesture track 120 is the current touch of the touch module 110. parts. the

The control unit 105 determines whether the end point 122 of the gesture track 120 is overlapped with an adjacent track on the gesture track 120 (step S420 ). This step is mainly to determine whether the finger slides backwards according to the gesture trajectory 120 when sliding on the touch module 110 . the

As shown in FIG. 6K , when it is judged to be overlapped, the overlapping traces of the gesture traces 120 are eliminated (step S421 ). The so-called overlap is mostly partial overlap. Since the part of the touch module 110 that the finger slides backwards according to the gesture trajectory 120 is bound to be different from the part of the touch module 110 touched by the previously drawn gesture trajectory 120, it is necessary to determine the part that should be eliminated in a partially overlapping manner. Local trajectory 123 . Next, set the end point 122 of the gesture trajectory 120 after eliminating the overlapping trajectory (step S422 ), as shown in FIG. 6L . the

If it is determined that there is no overlap, the control unit 105 determines that there is no need to delete the gesture track 120, and keeps updating the gesture track 120 (step S423). the

Please refer to FIG. 7A and FIG. 7B , FIG. 7A is a schematic diagram of the reserved track according to the second embodiment of the present invention, and FIG. 7B is a schematic diagram of the update of the gesture track according to the second embodiment of the present invention. the

As shown in FIG. 7A , regardless of the above-mentioned trajectory elimination rule, as long as the control unit 105 judges that the formation of the gesture trajectory 120 conforms to the trajectory elimination rule, the partial trajectory 123 of the gesture trajectory 120 is eliminated according to the trajectory elimination rule 107 (step S221) . the

Next, an error is corrected between the currently touched part of the touch module 110 and the end point 122 of the gesture track 120 (step S222 ). This step is mainly aimed at eliminating the partial trajectory 123 of the gesture trajectory 120, the end point 122 of the gesture trajectory 120 may not correspond to the current touched position of the touch module 110, so it is necessary to compare the end point 122 of the gesture trajectory 120 with the current position of the touch module 110. Error correction for the distance between touched locations. On the contrary, if it is determined that the trajectory elimination rule is not met, the gesture trajectory 120 is continuously updated (step S223 ). Afterwards, the control unit 105 determines whether the touch module 110 is still touched (step S230 ). the

If it is determined that the touch module 110 is still being touched, then return to step S210 to continue forming the gesture track 120 . As shown in FIG. 6D , FIG. 6G , FIG. 7A and FIG. 7B , the direction of the gesture track 120 is first down-left. Secondly, the user's finger slides backwards on the touch module 110 to form overlapping tracks or enter the error zone 130 . Next, the control unit 105 eliminates the local trajectory 123 generated according to the trajectory elimination law 107 . Finally, the finger continues to slide to form the gesture trajectory 120 that the user really needs, as follows - right. the

If it is judged that the touch module 110 is not touched, it means that the user's finger has left the touch module 110, and the gesture track 120 currently recorded is what he needs.
