Abstract

Display device is able to detect a proximity operation in which finger F is brought close to display surface without making contact and a contact operation in which the finger makes contact with display surface. Display device specifies a position of a finger of a user while in a stationary state above display screen as reference position BP1 or BP2 based on the proximate operation of the user. When display device specifies reference position BP1 or BP2 after screen SC1 including selectable objects is displayed on display surface, display device enlarges and displays objects located in specific region Ts according to the specified reference position (objects having reference sign “M” at the end). This allows for supporting the user in indicating by a contact operation of an object located at a position further away from the finger when the user operates display device with one hand.

Claims

1-10. -10. (canceled)

11. A user interface device comprising:

a display unit that displays an image on a display surface;

an operation detecting unit that detects a first operation in which a pointer is brought close to the display surface without making contact with the display surface, and a second operation in which the pointer is brought closer to the display surface than in the first operation;

a reference-position-specifying unit that specifies a reference position of the pointer based on the first operation detected by the operation detecting unit;

a display control unit that controls a display of an image including a selectable object on the display surface, and upon a specification of the reference position by the reference-position-specifying unit, controls a display of an object according to the specified reference position in a predetermined display manner for supporting an indication by the second operation; and

a selected-object-specifying unit that specifies, upon a detection by the operation detecting unit of a second operation indicating an object displayed on the display surface, the object as a selected object by a user.

12. The user interface device according to claim 11, wherein the display control unit controls a display of an object located in a specific region further away from the reference position by at least a predetermined distance in the predetermined display manner.

13. The user interface device according to claim 11, wherein the reference-position-specifying unit specifies, upon a position indicated by the first operation being continually included in a predetermined range for a predetermined period, a reference position located in the predetermined range.

14. The user interface device according to claim 11, wherein the pointer is a finger of a user;

the user interface device further comprising a determining unit that determines a hand of the user used to hold the user interface device based on the first operation detected by the operation detecting unit, and wherein

the display control unit controls a display of an object located at a position according to the hand determined by the determining unit and a length of the finger of the user, in the predetermined display manner.

15. The user interface device according to claim 11, further comprising a positional-relation-specifying unit that specifies a positional relation between an object according to the reference position and another object displayed on the display surface, and wherein

the display control unit controls a display of the object according to the reference position in the predetermined display manner upon the positional relation specified by the positional-relation-specifying unit satisfying a specific condition.

16. The user interface device according to claim 15, wherein the display control unit uses, as the specific condition, a condition in which the other object is disposed in a predetermined range from a position of the object according to the reference position.

17. The user interface device according to claim 11, wherein the display control unit uses an enlarged display of the object as the predetermined display manner.

18. The user interface device according to claim 11, wherein the display control unit uses a change of a display position of the object as the predetermined display manner.

19. A user interface method comprising:

an operation detecting step of detecting a first operation in which a pointer is brought close to a display surface, on which an image is displayed, without making contact with the display surface, and a second operation in which the pointer is brought closer to the display surface than in the first operation;

a reference-position-specifying step of specifying a reference position of the pointer based on the first operation detected in the operation detecting step;

a display control step of controlling a display of an image including a selectable object on the display surface, and upon a specification of the reference position in the reference-position-specifying step, controls a display of an object according to the specified reference position in a predetermined display manner for supporting an indication by the second operation; and

a selected-object-specifying step of specifying, upon a detection in the operation detecting step of a second operation indicating an object displayed on the display surface, the object as a selected object by a user.

20. A program for causing a computer of a display device that displays an image on a display surface, to execute:

an operation detecting step of detecting a first operation in which a pointer is brought close to the display surface without making contact with the display surface, and a second operation in which the pointer is brought closer to the display surface than in the first operation;

a reference-position-specifying step of specifying a reference position of the pointer based on the first operation detected in the operation detecting step;

a display control step of controlling a display of an image including a selectable object on the display surface, and upon a specification of the reference position in the reference-position-specifying step, controls a display of an object according to the specified reference position in a predetermined display manner for supporting an indication by the second operation; and

a selected-object-specifying step of specifying, upon a detection in the operation detecting step of a second operation indicating an object displayed on the display surface, the object as a selected object by a user.
