Abstract

An aspect of the invention includes a display device that operates controls on a display surface independent of a size of the display surface. A touch panel displays a screen on a display surface and inputs a user operation point on the display surface. An extracting part extracts controls that receive a touch operation of a user from content to be displayed on the display surface. A display controller displays auxiliary buttons for providing instructions for input of an extracted control, together with the content on the display surface.

Claims

1. A display device, comprising:

a touch panel that displays a screen on a display surface and inputs a user operation point on the display surface;

an extracting part that extracts controls that receive a touch operation of a user from content to be displayed on the display surface; and

a display controller that displays auxiliary buttons for providing instructions for input of an extracted one of the controls, together with the content on the display surface.

2. The display device according to claim 1, further comprising an input controller that provides instruction for inputting a corresponding control based on the user operating the auxiliary buttons.

3. The display device according to claim 1, wherein the display controller displays the auxiliary buttons on edge parts of the display surface.

4. The display device according to claim 1, wherein the display controller displays on the display surface the auxiliary buttons having a one-to-one correspondence to the controls.

5. The display device according to claim 4, wherein the display controller displays a plurality of the auxiliary buttons in a color that is the same as a color displayed on the display surface for the corresponding controls.

6. The display device according to claim 2, wherein:

the extracting part extracts row and column position information of the controls on the display surface;

the display controller places the auxiliary buttons in a horizontal direction and a vertical direction of the display surface based on the row and column position information of the controls; and

the input controller provides instructions for inputting the control located in a row and column corresponding to the auxiliary button operated by the user.

7. The display device according to claim 2, wherein:

the display controller assigns pre-established codes to the auxiliary buttons and assigns code sets to the controls, the code sets including a combination of a plurality of the pre-established codes; and

the input controller provides instructions to the corresponding controls based on the code sets corresponding to the plurality of auxiliary buttons operated by the user.

8. The display device according to claim 7, wherein the display controller displays the auxiliary buttons on the display surface together with assigned pre-established codes, and the controls are displayed on the display surface together with assigned code sets.

9. The display device according to claim 2, wherein the input controller:

causes one of the controls to be in a tentatively selected condition based on operation of a first auxiliary button by the user; and

transitions the tentatively selected condition of the control to another successive control based on operation of a second auxiliary button by the user.

10. The display device according to claim 1, wherein the display controller places the auxiliary buttons at positions that are more than a predetermined distance from a display position of a plurality of the controls on the display surface.

11. The display device according to claim 1, wherein the touch panel invalidates input from the user for controls that are placed on edge parts of the display surface.

12. The display device according to claim 1, wherein the extracting part is prevented from extracting controls that are placed on edge parts of the display surface.

13. The display device according to claim 1, wherein the extracting part extracts the controls from image information of the content.

14. The display device according to claim 1, wherein the extracting part extracts the controls from source code of the content.

15. The display device according to claim 1, wherein the extracting part receives information for the controls from an application that displays the content.

16. A display device, comprising:

a touch panel with a display surface; and

a display controller that displays controls on the display surface, and also displays auxiliary buttons that call out functions that are the same as functions of the controls on edge parts of the display surface.

17. A display method, comprising:

displaying content on a display surface;

inputting user operation points on the display surface;

extracting controls that receive touch operations of a user from the content to be displayed on the display surface; and

displaying auxiliary buttons for providing instructions for input to an extracted control, together with the content on the display surface.

18. The display method according to claim 17, further comprising providing instruction for inputting to a corresponding control based on the user operating the auxiliary buttons.

19. The display method according to claim 17, further comprising displaying the auxiliary buttons on an edge part of the display surface.

20. A computer program product comprising a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code configured to perform a method, the method comprising:

displaying content on a display surface of a display device;

inputting user operation points on the display surface;

extracting controls that receive touch operations of a user from the content to be displayed on the display surface; and

displaying auxiliary buttons for providing instructions for input to an extracted control, together with the content on the display surface.
