Abstract

A user input apparatus includes a display screen that displays selectable items; a receiving unit that receives operational input from a user; a display control unit that causes to be displayed on the display screen as objects, the selectable items and a 3-dimensional virtual space centered about a vantage point of the user viewing the display screen; a detecting unit that detects an angular state of the user input apparatus; a focusing unit that focuses a selectable item according to the detected angular state; and a control unit that performs control causing reception of selection that is made via the operational input from the receiving unit and with respect to the selectable item focused by the focusing unit.

Claims

1. A user input apparatus comprising:

a display screen that displays selectable items;

a receiving unit that receives operational input from a user;

a display control unit that causes to be displayed on the display screen as objects, the selectable items and a 3-dimensional virtual space centered about a vantage point of the user viewing the display screen;

a detecting unit that detects an angular state of the user input apparatus;

a focusing unit that focuses a selectable item according to the detected angular state; and

a control unit that performs control causing reception of selection that is made via the operational input from the receiving unit and with respect to the selectable item focused by the focusing unit.

2. The user input apparatus according to claim 1, wherein

the display control unit causes the 3-dimensional virtual space to be displayed as a sphere together with the selectable items displayed at given positions in the 3-dimensional virtual space, and

the focusing unit moves a focusing position in a direction identical to an angular direction of the user input apparatus.

3. The user input apparatus according to claim 1, wherein

the receiving unit includes a first receiving unit for performing photography, and

the control unit, when the selectable item is focused by the focusing unit, performs control causing reception of the selection that is made via the operational input from the first receiving unit and with respect to the focused selectable item.

4. The user input apparatus according to claim 3, wherein

the receiving unit includes a second receiving unit for zooming in or out from an object, and

the focusing unit causes zooming-in on or zooming-out from the selectable item based on the operational input from the second receiving unit.

5. The user input apparatus according to claim 1, wherein

the focusing unit sets a focusing position displayed when input commences as an initial position and focuses the selectable item.

6. The user input apparatus according to claim 1, wherein

the selectable item is a soft keyboard, and

the focusing unit focuses the soft keyboard according to the angular state detected by the detecting unit.

7. The user input apparatus according to claim 6, wherein

the selectable item is a character on the soft keyboard, and

the display control unit, in addition to focusable characters displayed on the soft keyboard, causes display of a character editing portion in which selected characters are displayed, and a candidate displaying portion in which character strings estimated from the characters displayed in the character editing portion are displayed.

8. The user input apparatus according to claim 7, wherein

the display controlling unit, when a character on the soft keyboard is focused by the focusing unit, causes fixed display of the character editing portion and the candidate display portion where the character editing portion and the candidate display portion do not move correspondingly with focus movement.

9. The user input apparatus according to claim 1, wherein

the detecting unit is formed by a triaxial accelerometer equipped in the user input apparatus.

10. A digital camera comprising:

the user input apparatus according to claim 1.

11. An input control method comprising:

receiving operational input from a user;

controlling display to cause to be displayed on a display screen as objects, selectable items and a 3-dimensional virtual space centered about a vantage point of the user viewing the display screen;

detecting an angular state;

focusing a selectable item according to the detected angular state; and

controlling to cause reception of selection that is made via the operational input at the receiving and with respect to the selectable item focused at the focusing.

12. A computer-readable recording medium storing therein an input control program that causes a computer to execute:

receiving operational input from a user;

controlling display to cause to be displayed on a display screen as objects, selectable items and a 3-dimensional virtual space centered about a vantage point of the user viewing the display screen;

detecting an angular state;

focusing a selectable item according to the detected angular state; and

controlling to cause reception of selection that is made via the operational input at the receiving and with respect to the selectable item focused at the focusing.
