[First Embodiment]
As an embodiment to which the present invention is applied, a stereoscope product attachment (hereinafter simply referred to as an “attachment” in the present embodiment) for wearing a smartphone equipped with a touch panel to enjoy a 3D stereoscopic image, and the attachment are supported. A remote touch circuit for enabling remote operation input to the touch panel with a finger will be described as an example. In addition, the meaning of "remote" described here means that it is away, and does not define the distance.

  The touch panel 1506 is a projected capacitive touch panel. That is, when the user touches, the human body (contacting object) acts as an impedance imparting body (capacitor such as a capacitor). Although alternating current of the same phase and the same potential is applied to the four corners of the touch panel 1506, when a finger or the like touches the touch panel 1506, the current changes according to the impedance of the human body. The contact coordinates in the coordinate system of the touch panel 1506 can be calculated from the ratio of the current detected at the four corners. That is, the human body can be regarded as an impedance imparting body that substantially changes the impedance. In addition, since a well-known technique can be utilized suitably for such a calculation method of a contact position, description is abbreviate | omitted in this specification.

On the screen of the touch panel 1506, an upper display area W2 and a lower display area W4 are set, and an operation input area W3 is set between these display areas.
The upper display area W2 and the lower display area W4 are on the right and left sides of the attachment 2 when the smartphone 1500 is attached to the attachment 2. Therefore, the control board 1550 of the smartphone 1500 controls to display the right-eye screen on the former and display the left-eye screen on the latter.

  Although nothing is displayed in the operation input area W3, a change in capacitance in the area is regarded as an operation input. In the present embodiment, the operation input area W3 further includes four virtual button positions W31 to W34 in the left-right direction (for the smartphone 1500), and at least four types of operation inputs are possible.

Next, the configuration of the attachment 2 will be described.

The cover part 42 includes a recess 43 on the inner side (the mating surface side with the attachment body 8). The concave portion 43 is a concave space that can accommodate the device holding plate 44 that is wide in both the vertical and horizontal directions.

FIG. 8 is a front view of the device holding plate 44, and shows (1) the smartphone 1500 is not mounted and (2) is mounted.
The device holding plate 44 is a plate material for fixing the smartphone 1500, and is made of a material having conductivity or electrostatic diffusion. Screw hole groups 44a are provided at the four corners on the inner surface side (the surface facing the attachment body 8 when the holding portion 4 is closed). Fasteners 45 that engage with the four corners of the smartphone 1500 are attached to the screw hole group 44 a with screws 46 so that the attachment positions are variable.

  The fastener 45 is formed of a soft elastic resin. When the smartphone 1500 is attached, the fastener 1500 is appropriately elastically deformed by the force of pushing the smartphone 1500, and the smartphone 1500 fits in the center of the four fasteners 45. The deformation returns to engage with the four corners of the smartphone 1500 to prevent it from falling off.

  The holding-side ground circuit portion 48 is an electrostatic diffusion film that is attached to the inner surface side of the recess 43, and its tip extends to the mating surface between the holding portion 4 and the attachment body 8. As long as the device holding plate 44 is fixed to the cover unit 42, the holding-side ground circuit unit 48 abuts against the outer surface of the device holding plate 44, and static electricity from the main body of the smartphone 1500 is discharged via the device holding plate 44. I can tell you.

  A partition wall 12 is provided in the center of the left and right of the attachment body 8, and defines a cylinder part that communicates with the right eyepiece part 7R and a cylinder part that communicates with the left eyepiece part 7L. The smartphone 1500 is supported and fixed to the holding unit 4 so that when the holding unit 4 is closed, the operation input area W3 is just at the position facing the front end of the partition wall 12.

The attachment body 8 includes a remote touch circuit 70 and an attachment body side ground circuit 80.
The remote touch circuit 70 includes an electric wire part 72, a conductive pad 76, and a button part 77.

  FIG. 9 is a partially enlarged view showing a configuration example of the electric wire portion 72 and shows a state in which the front end portion of the partition wall 12 is viewed from the front. The electric wire portion 72 is formed of a conductive or electrostatic diffusing material on a flexible sheet 73 formed of an antistatic material and having excellent bending properties, and the conductive line 74 is sealed.

  The conductive lines 74 are provided at least in the same number as the virtual button positions of the smartphone 1500, and one end thereof is attached to the front side of the partition wall 12 (the side facing the smartphone 1500 when the holding unit 4 is closed). One end side of the conductive line 74 forms a widened portion 75, and the holding portion 4 side is exposed outside the flexible sheet 73. A conductive pad 76 is detachably attached to the exposed surface of the widened portion 75.

  9 are (1) a longitudinal sectional view of the conductive pad 76 and (2) a view showing the lower surface (attached surface side). When the holding unit 4 is closed, the conductive pad 76 contacts the virtual button positions W31 to W34 set on the touch panel 1506 of the smartphone 1500 held by the holding unit 4. The conductive pad 76 of the present embodiment is a disk-shaped pad, and includes a conductive core portion 76 a exposed at both end faces, and an adhesive portion 76 b provided on the outer periphery of the contact side end portion with the widened portion 75. Is provided. The adhesive portion 76 b is an elastic resin that can be removed and re-adhered to the flexible sheet 73 and the conductive line 74. That is, the conductive pad 76 can be attached to the widened portion 73 of the conductive line 74 and the position of the conductive pad 76 is variable. These function as a position adjusting mechanism that adjusts the position where the conductive pad 76 contacts the touch panel 1506 (76 in FIG. 9). (Adjustable within the range of (up) to 76 (down)).

  As shown in FIGS. 4B and 7, the electric wire portion 72 is laid from the partition wall 12 to the upper portion of the attachment body 8, and the other end reaches the grip portion 9 of the attachment body 8. Each conductive line 74 of the electric wire portion 72 is connected to one of the button portions 77 provided on the grip portion 9. The grip 9 is non-conductive and formed of an antistatic material.

The button part 77 includes a button main body 78 formed of a conductive material, and an elastic resin cup part 79 connected to the side surface of the button main body.
The button body 78 is instructed by the cup portion 79 in a state of being floated immediately above the exposed portion of the conductive line 74. When the user pushes the button part 77 with a finger, the cup part 79 is elastically deformed and sinks, and the lower surface of the button body 78 comes into contact with the conductive line 74. That is, the human body that is the impedance imparting body can be electrically connected to the electric wire portion 72. When the force applied to the finger by the user is removed, the cup portion 79 is restored, and the contact between the button portion 77 and the conductive line 74 is released.

  4 (2) and FIG. 7, the attachment main body side ground circuit 80 is capable of electrostatically conducting the spring connection terminal 82, the ground sheet portion 84 provided at the lower part of the attachment main body 8, and both of them. And an earth wire 86 connected to the cable.

  The ground sheet portion 84 is a sheet material (or coating film) made of a conductive material, and is provided at a portion that comes into contact with a hand or fingers when the user grips the attachment body 8. In the present embodiment, the attachment 2 is assumed to be held with binoculars, with the index finger to the little finger attached to the grip 9 on the top surface of the attachment body 8 and the thumb attached to the bottom surface of the attachment body 8. The earth sheet portion 84 is provided on the lower surface of the attachment main body 8.

FIG. 10 is a circuit diagram of the remote touch circuit 70 in the present embodiment.
In the state where the holding unit 4 is closed, the main body of the smartphone 1500 is connected to the user's human body through the device holding plate 44, the holding-side ground circuit 48, and the attachment main-body-side ground circuit 80 so as to be electrically conductive, and is grounded. On the other hand, when the holding unit 4 is closed, the conductive pad 76 that protrudes from the front surface side of the partition wall 12 contacts the touch panel 1506.

  When the user presses the button part 77 with the finger F1, the touch panel 1506 is connected to the user's finger through the conductive pad 75 to the electric wire part 72 to the button part 77 so as to be electrically conductive. That is, impedance (capacitance such as a capacitor) due to the user's finger (human body) is substantially electrically connected to the touch panel 1506. Therefore, the touch panel 1506 can detect a current value corresponding to the impedance and recognize that the touch operation has been performed at the virtual button positions W31 to W34.

  As described above, according to the present embodiment, the attachment 2 that realizes the remote touch circuit for realizing the remote touch operation on the touch panel 1506 and enables the remote touch operation from the outside while incorporating the smartphone 1500 equipped with the touch panel 1506.

  Moreover, even if the model of the smartphone 1500 is different and a difference occurs in the outer shape or the setting positions of the virtual button positions W31 to W34, it can be dealt with by adjusting the plate position adjusting mechanism 50 or the attaching position of the conductive pad 76. .

[Modification]
As mentioned above, although embodiment which applied this invention was described, the form of this invention is not limited to this, A component can be added, abbreviate | omitted, and changed suitably.

[First Modification]
For example, the button unit 77 has a function of connecting to the impedance applying body called the human body and the remote touch circuit 70, but it can be configured to connect to the capacitive element instead of the human body. For example, the capacitive element 11 is built in like the attachment 2B shown in FIG. One terminal of the capacitive element 11 is connected to the attachment main body side ground circuit 80, and the other terminal is connected to the button unit 77. The button 77 can be configured to connect the terminal at the other end of the capacitive element 11 to the conductive line 74 when the button 77 is pushed. In this case, the remote operation to the touch panel 1506 can be realized even when the user is wearing gloves or the like and the capacitor is not properly formed between the button unit 77 and the user.

[Second Modification]
Moreover, in the said embodiment, although the model difference of the smart phone 1500 can be absorbed by the structure of the attachment 2, it is good also as a structure corresponding by the smart phone 1500 side. For example, a three-dimensional stereoscopic image generation program executed by the smartphone 1500 prompts the user to perform an operation on the button unit 77 as one of initialization operations before starting the image generation, and is detected by the operation. It is preferable to realize a virtual button position setting function for adjusting and setting the virtual button position according to the touch position.

  Specifically, a virtual button position setting process as shown in FIG. 12 is executed. That is, the control board 1550 of the smartphone 1500 executes an operation guidance step (step S2) for performing a display prompting the touch panel 1506 to operate all the buttons 77 simultaneously (or sequentially in accordance with a predetermined signal), A touch position detection step (step S4) for detecting the touch position is executed. Then, a virtual button position setting step (step S6) is executed in which the touch position detected in this step is stored and set as a virtual button position reference coordinate in the IC memory 1552 of the control board 1550. When a plurality of virtual buttons are prepared, sorting is performed according to the relative positional relationship between touch positions. When the touch position is detected within a predetermined range from the virtual button position reference coordinates during the process of generating the 3D stereoscopic video, the control board 1550 assumes that the corresponding virtual button is operated and controlled. good.

[Third Modification]
Moreover, the form of the attachment is not limited to a stereoscope product, but may be any other product form as long as it is a form that is attached to a computer equipped with a touch panel corresponding to the smartphone 1500.
For example, as shown in the attachment 2 </ b> C shown in FIG. 13, the game controller type attached to the home-use game apparatus is provided with an operation button 92 and a direction input key 94. And it can be set as the structure which performs the video game by a two-dimensional image | video with the smart phone 1500. FIG.

  In this configuration, the operation button 92 and the direction input key 94 correspond to the button unit 77 in the first embodiment. Electric wire portions 72R and 72L connected to the switches of the operation button 92 and the direction input key 94 and the holding plate 41 of the holding portion 4C are provided. The holding plate 41 is swingably supported by the attachment body 8 by the hinge 10 and can cover and fix a part of the touch panel 1506 of the smartphone 500. The holding plate 41 is brought into contact with the touch panel 1506 with the conductive pad 76 on the body surface side with the touch panel 1506 as in the above embodiment.

[Other variations]
In addition, the smartphone 1500 in the above embodiment can be appropriately replaced with another computer or electronic device including the touch panel 1506.
Further, although the end of the remote touch circuit 70 is the button unit 77, it may be configured as an input device other than the buttons (for example, a cross-shaped direction input key, a joystick, etc.)
Of course, depending on the sensitivity of the touch panel 1506, the grounding circuits of the device holding plate 44, the holding side ground circuit 48, and the attachment main body side ground circuit 80 can be omitted.
