(First embodiment)
FIG. 1 is a schematic diagram illustrating a configuration of an information processing apparatus 100 according to the first embodiment. FIG. 2 is a side view of the information processing apparatus 100 according to the present embodiment in the state of FIG.

  As illustrated in FIG. 1, the information processing apparatus 100 according to the present embodiment includes an electronic paper 120 and a control device 110. The electronic paper 120 is a display having a thickness of about several tenths of a millimeter and capable of displaying and erasing data by electrical means. In addition to the “easy-to-read, easy-to-carry” features of hard copies printed on paper media, the electronic paper 120 has “combinability / rewritability with digital information” and soft-copying resources that are displayed on a soft copy on a display screen. Is a reflection type display medium that is expected to realize the above, and has characteristics of ultrathinness and flexibility that are not found in conventional image display devices. The control device 110 performs control such as changing the display magnification of the display target data displayed on the screen of the electronic paper 120, and mainly includes a main body 111 and an attachment 112.

  The attachment portion 112 is for attaching the electronic paper 120. As shown in FIG. 2, the control device 110 attaches the electronic paper 120 by sandwiching the end portion of the electronic paper 120 between the main body 111 and the mounting portion 112, and releases the sandwiched state. The electronic paper 120 is removed and can be detached.

  Next, the internal configuration of the electronic paper 120 and the control device 110 of the information processing apparatus 100 according to the present embodiment will be described. FIG. 3 is a block diagram illustrating the configuration of the electronic paper 120 and the control device 110 of the information processing apparatus 100 according to the present embodiment.

  The electronic paper 120 accepts an operation caused by a user bending, and displays display target data. The electronic paper 120 mainly includes a display unit 321, a foil-like piezoelectric sensor 322, and an output unit 323.

  The display unit 321 displays and deletes display target data stored in a storage unit 311 described later, and is formed of a material that can be bent. In addition, the display unit 321 includes two display layers of an electrophoretic microcapsule, or a display layer of gyricon beads using solid particles coated in two colors, and a driver layer that controls any one of the display layers. Since the structure is sandwiched between two plastic sheets, the display screen of the display portion 321 remains displayed even when the power is turned off.

  The foil-like piezoelectric sensor 322 detects distortion of the display unit 321 that is curved by a user operation using an aluminum nitride foil film. In this embodiment, the foil-like piezoelectric sensor 322 is used as a strain detection sensor, but the present invention is not limited to this, and any sensor can be used as long as it can detect the strain of the display unit 321. Can do.

  Specifically, when a pressure is applied to the foil-like piezoelectric sensor 322, electric charges are induced on the electrodes formed on both surfaces thereof due to the piezoelectricity of the aluminum nitride thin film. The foil-shaped piezoelectric sensor 322 has a laminated structure in which three electrodes and two aluminum nitride thin film layers are alternately stacked. One inner electrode is an external environment by two outer electrodes. Completely shielded from. For this reason, it is effective for prevention of leakage (leakage) of generated charges to the outside and suppression of dielectric charges, and accurate detection of generated charges is possible even when directly contacting a conductor such as a human body. Furthermore, the aluminum foil and the aluminum nitride thin film that serve as the electrode and the substrate are in very close contact with each other, and the film is not peeled off due to the deformation of the substrate, so that no damage occurs. Therefore, the foil-like piezoelectric sensor 322 is thin and flexible, and can be applied to a curved surface or a biological surface.

  The foil voltage sensor 322 detects the distortion of the display unit 321 and sends the distortion amount as a detection signal. The detection signal is a signal indicating a current value due to the generated charge when strain is detected by the foil-like piezoelectric sensor 322. This detection signal takes a positive or negative current value, and when the detection signal is a positive current value, it indicates that the electronic paper 120 is curved in a convex shape with respect to the user, and is a negative current value. In the case, it indicates that the electronic paper 120 is curved in a concave shape with respect to the user. The amount of the current value of the detection signal indicates the amount of distortion. The larger the current value, the larger the amount of distortion.

  The output unit 323 sends the distortion amount of the display unit 321 detected by the foil-like piezoelectric sensor 322 to the control device 110 as a detection signal. Specifically, when the electronic paper 120 is curved by the foil-like piezoelectric sensor 322 in a convex shape with respect to the user, the positive distortion amount is sent to the control device 110 as a detection signal. When the distortion is detected when the electronic paper 120 is bent concavely with respect to the user by the foil-shaped piezoelectric sensor 322, a negative distortion amount is sent to the control device 110 as a detection signal.

  Here, the configuration of the electronic paper 120 will be described. FIG. 4 is an explanatory diagram showing an example of the configuration of the electronic paper 120. As shown in FIG. 4, a foil-like piezoelectric sensor 322 having the same area as that of the display unit 321 is sandwiched between the display unit 321 and the exterior cover 423 so as to be integrated.

  When the electronic paper 120 is bent by the user's operation, the control unit 312 detects that the distortion of the display unit 321 detected by the foil-shaped piezoelectric sensor 322 is bent convexly toward the user. In this case, when displaying the display target data on the display unit 321 of the electronic paper 120, control is performed to determine that the display content is enlarged and displayed. In addition, the control unit 312 displays the display target data on the electronic paper 120 when the distortion of the display unit 321 detected by the foil-shaped piezoelectric sensor 322 is detected by being bent concavely toward the user. When displaying on the unit 321, control is performed to determine that the display content is reduced and displayed.

  Further, the control unit 312 determines the display magnification to be enlarged in response to the distortion amount of the display unit 321 that is curved in a convex shape toward the user (curved in the first direction), and toward the user. Control for determining a display magnification to be reduced is performed in accordance with the distortion amount of the display unit 321 curved in a concave shape (curved in the second direction). The distortion amount (current value) is associated with the display magnification in advance so that the display magnification increases as the distortion amount increases, and the correspondence between the distortion amount and the display magnification is held in the storage unit 311. ing.

  The display control unit 313 enlarges or reduces the display contents when displaying the display target data on the display unit 321 at the display magnification determined by the control unit 312 based on the distortion amount of the display unit 321. Is to do.

  Next, a display magnification change process for display target data due to distortion of the display unit 321 in the information processing apparatus 100 according to the present embodiment configured as described above will be described. FIG. 5 is a flowchart illustrating a procedure of display magnification change processing for display target data due to distortion of the display unit 321 in the information processing apparatus 100.

Judgment is made based on whether the current value indicated by the signal is positive or negative (step S504).

  Here, a case where the display unit 321 is curved in a convex shape will be described. FIG. 6 is an explanatory diagram illustrating an example when the electronic paper 120 is bent into a convex shape by a user operation.

Then, the display control unit 313 enlarges and displays the display content of the display target data displayed on the display unit 321 at the enlargement rate determined by the control unit 312 (step S506).

  On the other hand, when it is determined that the received detection signal is detected when the display unit 321 is bent into a concave shape (step S504: concave shape), the control unit 312 displays the distortion amount indicated by the detected current value. Therefore, a reduction ratio corresponding to the determination is determined (step S507). Then, the display control unit 313 reduces and displays the display content of the display target data displayed on the display unit 321 at the reduction rate determined by the control unit 312 (step S508).
