INFORMATION INPUT DEVICE AND INFORMATION DISPLAY METHOD
First Claim
1. An information input device for obtaining, from a user, an instruction for an image displayed on a display screen, the information input device comprising:
- an indicator detection unit configured to detect at least one of a position and an orientation of an indicator in a three-dimensional space;
a pointer position setting unit configured to set a position on the display screen of a pointer to be displayed on the display screen, in correspondence with the at least one of the position and the orientation of the indicator in the three-dimensional space detected by the indicator detection unit;
a storage unit configured to obtain and store time-sequenced positional information which indicates the position set by the pointer position setting unit;
a first passage detection unit configured to detect that the pointer has passed through a first specific region which is a predetermined region on the display screen, using the time-sequenced positional information stored in the storage unit;
a direction obtainment unit configured to obtain a direction in which the pointer has passed through the first specific region, if the first passage detection unit detects that the pointer has passed through the first specific region; and
a first image modifying unit configured to modify the image displayed on the display screen, depending on the direction obtained by the direction obtainment unit.

Abstract
An information input device including: an indicator detection unit (42); a pointer position setting unit (44) which sets a position of a pointer to be displayed on a display screen (52); a storage unit (46) which obtains and stores time-sequenced positional information which indicates the set position; a first passage detection unit (48) which detects that the pointer has passed through a first specific region which is a predetermined region on the display screen, using the time-sequenced positional information; and a direction obtainment unit (50) which obtains a direction in which the pointer has passed through the first specific region if it is detected that the pointer has passed through the first specific region; and a first image modifying unit (62) which modifies a displayed image, depending on the obtained direction.

19. An information input method executed by a device for obtaining, from a user, an instruction for an image displayed on a display screen, the information input method comprising:
-
(a) detecting at least one of a position and an orientation of an indicator in a three-dimensional space; (b) setting a position on the display screen of a pointer to be displayed on the display screen, in correspondence with the at least one of the position and the orientation detected in step (a); (c) obtaining and storing time-sequenced positional information which indicates the position set in step (b); (d) detecting that the pointer has passed through a first specific region which is a predetermined region on the display screen, using the time-sequenced positional information stored in step (c); (e) obtaining a direction in which the pointer has passed through the first specific region, if it is detected in step (d) that the pointer has passed through the first specific region; and (f) modifying an image displayed on the display screen, depending on the direction obtained in step (e). - View Dependent Claims (20)

21. An information display method executed by a computer, the information display method comprising:
-
(a) displaying one or more items on a display screen; and (b) obtaining an instruction from a user by detecting at least one of a position and an orientation of an indicator in a three-dimensional space, step (a) having; a first mode in which at least one item is selected from among the one or more items in accordance with the instruction from the user obtained in step (b); and a second mode in which a process involving modification of display of the at least one item selected in the first mode is performed, wherein if the instruction from the user obtained in step (b) is to cause movement from one of two or more regions set on the display screen to any of remaining regions, the first mode is switched to the second mode or the second mode is switched to the first mode. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29)

30. An information display device comprising a computer and a display screen, the computer executing:
-
(a) displaying one or more items on the display screen; and (b) obtaining an instruction from a user by detecting at least one of a position and an orientation of an indicator in a three-dimensional space, step (a) having; a first mode in which at least one item is selected from among the one or more items in accordance with the instruction from the user obtained in step (b); and a second mode in which a process involving modification of display of the at least one item selected in the first mode is performed, wherein if the instruction from the user obtained in step (b) is to cause movement from one of two or more regions set on the display screen to any of remaining regions, the first mode is switched to the second mode or the second mode is switched to the first mode.
