Abstract: An information input device including: an indicator detection unit; a pointer position setting unit which sets a position of a pointer to be displayed on a display screen; a storage unit which obtains and stores time-sequenced positional information which indicates the set position; a first passage detection unit 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 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 which modifies a displayed image, depending on the obtained direction.

Abstract: An information processing method is performed by an information processing apparatus, for executing predetermined processing in relation to an object displayed on a screen. The information processing method includes: obtaining position information indicating positions detected for two or more parts of an operating body; calculating a control amount on a basis of the positions of the two or more parts, the positions being indicated in the position information; and controlling including displaying, on the screen, a control symbol including a first symbol which represents the control amount calculated in the calculating and a second symbol which represents a threshold to be a criterion for determining whether or not the control amount satisfies a predetermined condition, and executing the predetermined processing in a case where the control amount is determined to satisfy the predetermined condition.

Abstract: An instruction input device includes: a first direction detection unit detecting the first direction in which the user is looking; a second direction detection unit detecting a second direction in which the user is performing a pointing operation; a gaze position calculation unit calculating a gaze position of the user on the screen; a reference coordinate group calculation unit calculating a reference line in space corresponding to the gaze position and connecting the user and the screen; an offset amount calculation unit calculating a distance of the second direction between the reference line and the input coordinate indicating the user's hand as an offset amount with respect to the gaze position; and a pointer display position calculation unit calculating a position in which a distance of the first screen predetermined direction between the position and the gaze position is the offset amount on the screen.

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.

Abstract: A user interface device (1) includes: a detection unit (3) which detects a position of a user; a display unit (2) which displays a work space; and a control unit (4) which controls display of an independent object which belongs to no user. The control unit (4) moves the independent object in a mode which varies between when the independent object is in a face-to-face space of the display unit (2) which is face to face with the position of the user and when the independent object is outside the face-to-face space. The control unit (4) also stops the moving independent object in a workspace assigned to the user when the user obtains the independent object.
