INFORMATION INPUT DEVICE AND INFORMATION DISPLAY METHOD

摘要

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.

主权项

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.
