May be. Further, the adjustment parameters from which data is acquired are not limited to the above four, and are not particularly limited as long as they relate to the wearability.

  The adjustment value calculation unit 13 includes an arithmetic processing unit including an arithmetic program for calculating an adjustment value for adjusting the wearability of the spectacle frame 100 from the wearability information acquired by the information acquisition unit 12. In the present embodiment, the adjustment value calculation unit 13 is configured integrally with the control unit 16. The adjustment value calculation unit 13 includes a memory for storing a prescribed value for each item, and the prescribed value for each item is compared with the measurement value acquired by the data acquisition unit, and what is necessary and how much adjustment is necessary. It has a function to calculate. Instead of providing a memory for storing the prescribed value, the latest data of the prescribed value may be acquired from the outside by wired or wireless communication means.

  In the present embodiment, the adjustment value calculation unit 13 calculates a temple adjustment value for adjusting the adhesion of the temple 101 from the area and pressure data, and calculates an inclination adjustment value for adjusting the inclination of the eyeglass frame from the inclination data. The intercorneal apex distance adjustment value for adjusting the intercorneal apex distance is calculated from the data related to the intercorneal apex distance, and the distance between the left and right rims 103 of the eyeglass frame 100 is adjusted according to the interpupillary distance from the data related to the interpupillary distance. The rim interval adjustment value is calculated.

  The wearability adjusting unit 14 includes various mechanisms that adjust the wearability of the eyeglass frame to the wearer using the various adjustment values. Specifically, the wearability adjustment unit 14 of the present embodiment includes a temple adjustment unit 40 for adjusting the adhesion of the temple 101 to the head, and an inclination adjustment unit 42 for adjusting the inclination of the glasses frame with respect to the head horizontal. The corneal apex distance adjusting unit 44 for adjusting the corneal apex distance and the rim adjusting unit 46 for adjusting the rim interval are provided.

  Specific configurations of the information acquisition unit 12, the adjustment value calculation unit 13, and the wearability adjustment unit 14 will be described.

  The contact pressure distribution data acquisition unit 20 is not particularly limited as long as it can acquire data relating to the area where the temple 101 is touching the wearer's head and the pressure applied to the head. FIG. 3A is a schematic diagram illustrating a specific configuration example of the contact pressure distribution data acquisition unit 20.

  As shown in FIG. 3A, the contact pressure distribution data acquisition unit 20 can be composed of a piezoelectric sensor 21 that can be attached to the wearer's head side surface 101 a of the temple 101. A plurality of point-shaped sensors or a surface sensor is disposed in an area that may come into contact with the wearer's head. With these two-dimensional sensors, it is possible to acquire a pressure distribution at a location where the head is touched. At this time, an electrical signal corresponding to the contact pressure is acquired from the piezoelectric sensor 21, and the contact area and pressure distribution in the region provided with the piezoelectric sensor can be acquired.

  As the contact state of the temple with the head of the wearer, it is preferable that the contact area is wide and the contact pressure is in an appropriate range. The contact pressure is preferably small and uniform. Moreover, the range of about 0.5 MPa-15 MPa is known as a range which implement | achieves preferable mounting | wearing property. The adjustment value calculation unit 13 holds, as a reference value, for example, the minimum size of an area to be contacted and the preferable range of the contact pressure value in a memory, and is acquired by the contact pressure distribution data acquisition unit 20. The temple adjustment value is calculated by comparing the pressure distribution data and the reference value. For example, when the acquired maximum contact pressure falls below the reference value range (= pressure is weak), the temple adjustment value is calculated to increase the adhesion of the temple, while the maximum contact pressure exceeds the reference value range. If the pressure is high, the temple adjustment value is calculated so as to reduce the adhesion of the temple.

  For example, as illustrated in FIG. 3B, the temple adjusting unit 40 is an actuator that applies tension to the wire 41 a disposed along the temple length direction on the temple 101 and the wire 41 a provided at one end of the wire 41 a. 41b, and adjust the adhesion of the temple 101 to the wearer's head using the temple adjustment value. In the initial state, the wire 41a is kept in a state of being tensioned with a constant tension by the actuator 41b. On the other hand, in order to increase the adhesion, the modernity of the temple 101 is bent toward the head by driving the actuator 41b to increase the tension applied to the wire 41a. On the other hand, when the adhesion is lowered, the actuator 41b is driven to reduce and loosen the tension applied to the wire 41a, whereby the modernity of the temple 101 is bent in a direction away from the head side. The adjustment value calculation unit 13 calculates an adjustment value for increasing or decreasing the tension by the actuator 41b. For example, if the relationship between the tension change and the bending change amount is acquired in advance, the tension change amount can be calculated as the adjustment value.

  The tilt data acquisition unit 22 is not particularly limited as long as data regarding the tilt of the eyeglass frame 100 from the wearer's head horizontal can be acquired. FIG. 4A is a schematic diagram illustrating a data acquisition method by the inclination data acquisition unit 22.

  As shown in FIG. 4A, the tilt data acquisition unit 22 includes an infrared in camera 25 provided on the rim 103 of the glasses frame 100, and acquires data related to the tilt of the glasses frame from shooting information obtained by the infrared in camera 25. The infrared in-camera 25 is provided at the lower center portion of the left and right rims 103 and is arranged so as to be able to photograph the wearer's eyes 5. Here, “in-camera” refers to a camera facing the face side. The eye 5 of the wearer with the wearer facing forward is imaged, and data relating to the inclination of the eyeglass frame from the wearer's head level is obtained.

  For example, in the tilt data acquisition unit 22, the position where the center of the pupil should originally be from the position of the infrared in camera 25 is defined as a default value. The left and right eyes are respectively photographed by the left and right in-cameras, and the actual center position (measured value) of the pupil on the image is detected. The difference between the default value and the actual measurement value on the left and right images is calculated. The angle formed by the straight line connecting the default values in the left and right images and the straight line connecting the actual measurement values can be calculated as the inclination of the eyeglass frame from the horizontal direction of the wearer's head.

  Here, the “head horizontal” is a straight line that connects the measured values of the left and right, and is defined by a straight line A that connects the center of the left and right eyes (the center of the pupil 5a) when the wearer is facing the front. A straight line B connecting the left and right infrared in-cameras 25 is horizontal to the glasses frame, and this is parallel to the straight line connecting the default values in the left and right images. The inclination θ of the eyeglass frame horizontal (straight line B) with respect to the head horizontal (straight line A) shown in FIG. 4A corresponds to “the inclination of the eyeglass frame from the wearer's head horizontal”.

  Note that the location and number of infrared in-cameras 25 are not limited to those in the present embodiment as long as the left and right eyes of the wearer can be photographed and the center position of the pupil can be specified.

  As a wearing state, it is preferable that the horizontal of the spectacle frame 100 and the horizontal of the head coincide. That is, the specified tilt value of the adjustment value calculation unit 13 is 0 °, and the tilt adjustment value is calculated so that the tilt θ acquired as described above becomes the specified value 0 °.

  The tilt adjustment unit 42 is a mechanism that is provided in, for example, a connection portion between the front of the spectacle frame 100 and the left and right temples 101 and adjusts the tilt of the front with respect to the horizontal of the head using the tilt adjustment value. Specifically, as shown in FIG. 4B, the inclination adjusting unit 42 includes a slide mechanism 42 a that allows the temple 101 to slide in the vertical direction with respect to the rim 103 and a linear servo motor (not shown) that drives the slide mechanism 42 a. can do. When such an inclination adjustment unit 42 is provided, the adjustment value calculation unit 13 calculates an adjustment value for designating the slide amount and direction of the slide mechanism 42a for this linear servo motor.

  In addition, as shown in FIG. 4C, the inclination adjusting unit 42 includes a rotation mechanism 42b that allows the temple 101 to rotate with respect to the rim 103 in order to change the connection angle of the temple 101 to the rim 103, and a rotation mechanism 42b. It is also possible to constitute a rotary servo motor (not shown) that drives the motor. When such an inclination adjusting unit 42 is provided, the adjustment value calculating unit 13 calculates an adjustment value that designates the rotation amount and the rotation direction of the rotation mechanism 42b by the rotation servomotor.

  The corneal apex distance data acquisition unit 24 is not particularly limited as long as data on the corneal apex distance can be acquired. FIG. 5A and FIG. 5B are schematic diagrams showing a method for obtaining the distance between corneal apexes.

  As shown in FIG. 5A, the corneal apex distance data acquisition unit 24 includes an infrared in camera 25 provided on the rim 103 of the eyeglass frame 100, and acquires data on the corneal apex distance from imaging information obtained by the infrared in camera 25. To do. The infrared in camera 25 is also used as the tilt data acquisition unit 22. As shown in FIG. 5A, the infrared in camera 25 images the eye 5 when the wearer looks at the right, and as shown in FIG. 5B, the eye 5 when the wearer looks at the left. To do. The shape of the pupil 5a can be extracted from each captured image, the wearer's line-of-sight direction can be calculated from the shape of the pupil, and the intercorneal vertex distance can be calculated by trigonometry.

  As shown in FIG. 5C, the corneal apex distance is a distance C between the rear apex 110a of the spectacle lens 110 and the cornea apex 5b. In general glasses for correcting vision, this distance C is set to 12 mm. Designed as That is, the prescribed value of the corneal vertex distance that the adjustment value calculating unit 13 has is 12 mm, and the difference from the prescribed value is calculated from the data regarding the corneal vertex distance data obtaining unit 24, and the corneal vertex difference is obtained. The vertex distance adjustment value is calculated.

  For example, as shown in FIG. 5C, the corneal apex distance adjusting unit 44 includes a slide mechanism 45 a that slides the nose pad 104 provided in the spectacle frame 100 in an approaching direction or a separating direction with respect to the front, and a slide mechanism 45 a. And a linear servo motor 45b to be driven, and the corneal vertex distance C is adjusted by driving the linear servo motor based on the corneal vertex distance adjustment value. When the corneal apex distance C is increased, the corneal apex distance adjustment unit 44 slides the slide mechanism 45a in a direction in which the nose pad 104 extends toward the wearer's face, thereby reducing the corneal apex distance C. In this case, the slide mechanism 45a is slid in a direction in which the nose pad 104 is separated from the face of the wearer. The adjustment value calculation unit 13 calculates an adjustment value for adjusting the distance by which the slide mechanism 45a is slid by the linear servo motor 45b.

  The interpupillary distance data acquisition unit 26 is not particularly limited as long as data regarding the interpupillary distance of the wearer can be acquired. FIG. 6A is a schematic diagram illustrating a data acquisition method by the interpupillary distance data acquisition unit 26.

  As shown in FIG. 6A, the interpupillary distance data acquisition unit 26 includes an infrared in camera 25 provided on the rim 103 of the eyeglass frame 100, and acquires data related to the interpupillary distance from imaging information obtained by the infrared in camera 25. The infrared in camera 25 also serves as the tilt data acquisition unit 22 and the corneal apex distance data acquisition unit 24. As shown in FIG. 6A, the infrared in camera 25 images the eye 5 of the wearer with the wearer facing forward, and measures the distance between the centers of the black eyes (the pupil 5a center). This interpupillary distance data acquisition unit 26 can be shared with the inclination data acquisition unit 22.

  It is preferable that the distance between the pupils 5a (distance D in FIG. 6B) matches the distance between the left and right lens centers. That is, the adjustment value calculation unit 13 has the distance between the left and right lens centers as a specified value, and adjusts the distance between the left and right rims 103 so that the distance between the pupils 5a and the distance between the left and right lens centers coincide. The rim interval adjustment value to be calculated is calculated. The initial value of the prescribed value of the distance between the left and right lens centers is, for example, a general interpupillary distance, male 64 mm, female 62 mm.

  The inter-rim adjustment unit 46 adjusts the distance between the rims of the eyeglass frame 100 using the inter-pupil distance adjustment value. For example, as shown in FIG. 6B, the inter-rim adjustment unit 46 includes a slide mechanism 46a that changes the distance between the left and right rims 103 of the eyeglass frame 100, and a linear servo motor (not shown) that drives the slide mechanism 46a. be able to.

Therefore, when the interpupillary distance is larger than the initial lens center distance and the interrim distance is increased, the slide mechanism 46a is slid in the direction in which the bridge 106 is extended so that the interpupillary distance is smaller than the initial lens center distance. When the distance is narrowed, the slide mechanism 46a is slid in the direction in which the bridge 106 is contracted. When such an inter-rim adjustment unit 46 is provided, the adjustment value calculation unit 13 calculates an adjustment value for designating the slide amount and slide direction of the slide mechanism 46a for this linear servo motor.

  It is preferable that at least a part of the information acquisition unit 12 and / or at least a part of the wearability adjustment unit 14 is modularized and configured to be replaceable with the eyeglass frame 100. For example, the piezoelectric sensor 21 of the contact pressure distribution data acquisition unit 20, the wire 41a of the temple adjustment unit 40, and the actuator 41b are preferably modularized. Similarly, it is preferable that the infrared in camera 25, the linear servo motor, the rotary servo motor, and the like are also modularized and exchangeable.

The attachment / detachment detection unit 15 can detect attachment / detachment of the glasses 10 to / from the wearer, for example, by detecting the opening / closing state of the temple 101 using an opening / closing sensor. As the open / close sensor, for example, a limit switch that is turned on when the temple 101 is closed and turned off when the temple 101 is opened can be used.

  Further, the method for detecting the attachment / detachment of the glasses 10 to / from the wearer is not limited to the above method, and for example, a contact sensor is provided on the ear hook portion of the temple 101 or the nose pad 104 of the glasses frame 100, and the contact sensor. Thus, by detecting the close contact with the skin, the wearing and detaching of the glasses 10 to the wearer may be detected. As the contact sensor, for example, a pressure sensor that outputs a signal corresponding to pressure can be used.

  Moreover, you may make it detect mounting | wearing and removal | desorption of the spectacles 10 with respect to the wearer by detecting the motion of a wearer's eyeball with a motion sensor (equivalent to a motion detection part). As the motion sensor, for example, a sensor provided with a light emitting element such as an LED (Light Emitting Diode) and a light receiving element such as a PD (Photo Detector) can be used. The motion sensor detects the movement of the eyeball (mainly the black eye) from the change in the amount of light received by the light receiving element accompanying the movement of the black eye. Attachment or detachment may be detected depending on whether or not black eyes can be detected by this motion sensor. When black eyes are detected, it is determined to be worn, and when black eyes are not detected for a certain period of time, it is determined to be detached.

  When it is detected by the attachment / detachment detection unit 15 that the glasses 10 are attached to the wearer, the control unit 16 starts acquiring wearability information by the information acquisition unit 12, and the glasses 10 are detached from the wearer. If the information acquisition unit 12 is acquiring the wearability information, the information acquisition process is stopped. If the wearability adjustment unit 14 is adjusting the wearability, the wearability adjustment process is performed. To stop.

  Note that the acquisition start and stop of the mounting information by the information acquisition unit 12 and the stop of the mounting adjustment process by the mounting property adjustment unit 14 may be controlled based on other conditions. Specifically, for example, when the wearer is continuously watching a preset position for a preset time or longer, the acquisition of the wearing information by the information acquisition unit 12 may be started.

  Next, a series of operations for wearability adjustment by the wearability adjustment glasses system 1 (wearability adjustment glasses 10) of the present embodiment will be described with reference to the flowchart shown in FIG.

  First, a wearer (user) wears the glasses 10. When this attachment operation is detected by the attachment / detachment detection unit 15 (S10, YES), the information acquisition function of the information acquisition unit 12 is turned on by the control of the control unit 16 (S12), and each data acquisition unit 20, Data acquisition by 22, 24 and 26 is performed (S14). Here, the acquisition of contact pressure distribution data, inclination data, corneal apex distance data, and interpupillary distance data is performed simultaneously or at any time. The data acquisition method by each of the data acquisition units 20, 22, 24, and 26 is as described above.

  Thereafter, the data acquired by each of the data acquisition units 20, 22, 24 and 26 is sent to the adjustment value calculation unit 13 via the control unit 16, and the adjustment value calculation unit 13 calculates various adjustment values (S16). ). Specifically, the temple adjustment value is calculated from the contact pressure distribution data, the inclination adjustment value is calculated from the inclination data, the intercorneal apex distance calculation value is calculated from the intercorneal apex distance data, and the interrim distance data is calculated from the interpupillary distance data. A distance adjustment value is calculated.

  Thereafter, the control unit 16 determines whether or not adjustment is necessary from the various adjustment values calculated by the adjustment value calculation unit 13 (S18). Note that this adjustment necessity determination may be made by the adjustment value calculation unit 13. When adjustment is required (S18, YES), an adjustment instruction is given from the control unit 16 to the wearability adjustment unit 14, and adjustment is performed by each of the adjustment units 40, 42, 44, and 46 of the wearability adjustment unit 14. (S20). Adjustment by each adjustment unit is performed simultaneously or sequentially. On the other hand, when the adjustment is unnecessary (S18, NO), the series of wearability adjustment processing is terminated.

  The necessity of adjustment for each adjustment value is basically determined in advance by setting a threshold for whether or not adjustment is necessary for each adjustment value. If so, it is determined that adjustment is unnecessary. On the other hand, a criterion for determining whether or not the entire eyeglasses need to be adjusted is arbitrary. For example, when all adjustment values are determined to require adjustment, when any one of the adjustment values is determined to require adjustment, or when a highly important adjustment parameter is determined to require adjustment It is determined that adjustment is necessary. A method for setting the level of importance and the number of parameters to be set when the importance is high is also arbitrary.

  After the wearability adjustment (S20), the processes of steps S12 to S20 are repeated until the information acquisition function of the information acquisition unit 12 is turned on again and the mounting information acquisition process is performed and adjustment is not necessary.

  In the above, a series of processes for adjusting the wearability is started when the wearing / removal detecting unit 15 detects wearing of the glasses. However, an external button for starting the wearability adjustment process is provided, When the button is pressed, the function may be turned on and the process may be started.

  Further, as described above, the adjustment process may be completed by one adjustment without repeating until it is determined that the adjustment is unnecessary. Alternatively, an upper limit may be set for the number of repetitions (for example, three times) in advance, and the adjustment process may be set to end after a predetermined number of adjustments has been repeated.

  Further, the configuration may not be such that all the wearability data is acquired and adjusted every time. Adjustments at one location may affect the wearability at other locations. For example, the most adjustment is required by acquiring wearability data (adjustment value with the largest difference from the specified value). By repeating the process of prioritizing the adjustment of the determined portion, then acquiring the wearability data again, and adjusting the portion that needs the most adjustment in this second wearability data acquisition The wearability may be gradually improved.

  In addition, when the wearability acquisition unit includes a plurality of data acquisition units related to wearability, it is not always necessary to acquire all wearability data. In a normal adjustment process, either one or Data may be acquired and adjusted only for parameters that are considered to contribute most to the wearability, such as two.

  FIG. 8 is a perspective view showing a schematic configuration of the wearability adjusting glasses system 2 according to the second embodiment of the present invention. As shown in FIG. 8, the wearability adjustment glasses system 2 of the present embodiment is composed of adjustment value reception type wearability adjustment glasses 10A (hereinafter referred to as glasses 10A) and an electronic terminal 10B. The glasses 10A and the electronic terminal 10B can transmit and receive data by wireless or priority communication means.

FIG. 9 is a functional block diagram of the wearability adjusting glasses system 2 of the present embodiment.

However, an adjustment value input unit that receives an adjustment value that is manually input may be provided as the adjustment value receiving unit. For example, as the adjustment value input unit, an image projection unit and an operation button are provided in the lens frame, the setting value input screen is displayed on the lens by the image projection unit, and the operation button is operated. One may be used for increasing the numerical value, and the other may be used for decreasing the numerical value, and the adjustment value may be increased, decreased, or fixed, for example, by pressing twice in succession. Alternatively, as the adjustment value input unit, a voice input unit may be provided in the glasses frame, and input of the adjustment value may be input by voice. In this case, the electronic terminal 10B prints the adjustment value as an adjustment value output unit, not as a wired or wireless communication unit, but as a display unit that displays the adjustment value on a display screen, or on a print medium such as paper. What is necessary is just to comprise as a printing part.

  A series of operations for wearability adjustment in the wearability adjustment glasses system 2 of the present embodiment will be described with reference to the flowchart shown in FIG. In the drawing, the flow on the left is a process in the glasses 10A, and the flow on the right is a process in the electronic terminal 10B.

  First, a wearer (user) wears glasses 10A. When this attachment operation is detected by the attachment / detachment detection unit 15 (S30, YES), the information acquisition function of the information acquisition unit 12 by the information acquisition unit 12 is turned on by the control of the control unit 16 (S32). Then, data acquisition by the data acquisition units 20, 22, 24 and 26 is performed (S34). Here, the acquisition of contact pressure distribution data, inclination data, corneal apex distance data, and interpupillary distance data is performed simultaneously or at any time. The data acquisition method by each of the data acquisition units 20, 22, 24, and 26 is as described above.

  Thereafter, the data acquired by the data acquisition units 20, 22, 24, and 26 of the information acquisition unit 12 is transmitted to the electronic terminal 10B by the control unit 16 via the data transmission / reception unit 18 (S36). On the electronic terminal 10B side, when various data relating to wearing are received (S50, YES), the adjustment value calculation unit 13 calculates an adjustment value based on the various data (S52), and outputs the adjustment value to the glasses 10A (S54). ). Specifically, the adjustment value calculation unit 13 calculates a temple adjustment value from the contact pressure distribution data, calculates an inclination adjustment value from the inclination data, and calculates a corneal vertex distance calculation value from the corneal vertex distance data. The rim distance adjustment value is calculated from the interpupillary distance data.

  On the side of the glasses 10A, when the adjustment value is received from the electronic terminal 10B (S38, YES), the control unit 16 determines whether adjustment is necessary (S40). When it is determined that adjustment is necessary (S40, YES), an adjustment instruction is given from the control unit 16 to the mounting property adjusting unit 14, and the adjusting units 40, 42, 44 of the mounting property adjusting unit 14 and Adjustment by / or 46 is performed (S42). Adjustment by each adjustment unit is performed simultaneously or sequentially. On the other hand, when the adjustment is unnecessary (S44, NO), the series of wearability adjustment processing is terminated.

  The determination as to whether adjustment is necessary for each adjustment value and the determination as to whether adjustment is necessary for the glasses as a whole are the same as in the adjustment glasses system of the first embodiment described above.

  After the wearability adjustment (S42), the above-described process is repeated until the information acquisition function of the information acquisition unit 12 is turned on again and the mounting information acquisition process is performed and adjustment is not necessary.

Alternatively, an upper limit may be set for the number of repetitions (for example, three times) in advance, and the adjustment process may be set to end after a predetermined number of adjustments has been repeated.

  Further, the flow is not limited to the acquisition and adjustment of all wearability data every time. Adjustments at one location may affect the wearability at other locations. For example, the most adjustment is required by acquiring wearability data (adjustment value with the largest difference from the specified value). By repeating the process of prioritizing the adjustment of the determined portion, then acquiring the wearability data again, and adjusting the portion that needs the most adjustment in this second wearability data acquisition The wearability may be gradually improved.

  In addition, when the wearability acquisition unit includes a plurality of data acquisition units related to wearability, it is not always necessary to acquire all wearability data. In a normal adjustment process, either one or Data may be acquired and adjusted only for parameters that are considered to contribute most to the wearability, such as two. Further, the wearer may be configured to select which parameter data is to be acquired or which parameter is to be adjusted. In this case, for example, in the case of the second embodiment, it is only necessary that the wearer can select and set parameters in the application on the electronic terminal side.
