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.

21. An instruction input device which calculates a display position of a pointer to be displayed on a screen, based on a pointing operation of movement of a hand of a user, the instruction input device comprising:
-
a user position detection unit configured to detect a position of the user; an input coordinate detection unit configured to detect, as an input coordinate, a coordinate indicating a position of the hand of the user; a first direction detection unit configured to detect, based on a body posture of the user, a first direction which is determined with respect to a screen vertical direction and is a direction in which the user is looking; a second direction detection unit configured to detect, based on the body posture of the user, a second direction which is determined with respect to a screen horizontal direction and is a direction in which the user is performing the pointing operation; a gaze position calculation unit configured to calculate a gaze position of the user on the screen, based on the position of the user and the first direction; a reference line calculation unit configured to calculate a reference line in space between the user and the screen, based on the position of the user and the first direction, the reference line being a line corresponding to the gaze position; an offset amount calculation unit configured to calculate a distance in the second direction between the reference line and the input coordinate as an offset amount with respect to the gaze position in a first screen predetermined direction along the screen; and a pointer display position calculation unit configured to calculate, as the display position of the pointer to be displayed on the screen, 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. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)

37. An instruction input method for calculating a display position of a pointer to be displayed on a screen, based on a pointing operation of movement of a hand of a user, the instruction input method comprising:
-
detecting a position of the user; detecting, as an input coordinate, a coordinate indicating a position of the hand of the user; detecting, based on a body posture of the user, a first direction which is determined with respect to a screen vertical direction and is a direction in which the user is looking; detecting, based on the body posture of the user, a second direction which is determined with respect to a screen horizontal direction and is a direction in which the user is performing the pointing operation; calculating a gaze position of the user on the screen, based on the position of the user and the first direction; calculating a reference line in space between the user and the screen, based on the position of the user and the first position, the reference line being a line corresponding to the gaze position; calculating a distance in the second direction between the reference line and the input coordinate as an offset amount with respect to the gaze position in a first screen predetermined direction along the screen; and calculating, as a display position of the pointer to be displayed on the screen, a position in which a distance in the first screen predetermined direction between the position and the gaze position is the offset amount on the screen.

38. A program recorded on a non-transitory recording medium for calculating a display position of a pointer to be displayed on a screen, based on a pointing operation of movement of a hand of a user, the program causing a computer to execute:
-
detecting a position of the user; detecting, as an input coordinate, a coordinate indicating a position of the hand of the user; detecting, based on a body posture of the user, a first direction which is determined with respect to a screen vertical direction and is a direction in which the user is looking; detecting, based on the body posture of the user, a second direction which is determined with respect to a screen horizontal direction and is a direction in which the user is performing the pointing operation; calculating a gaze position of the user on the screen, based on the position of the user and the first direction; calculating a reference line in space between the user and the screen, based on the position of the user and the first position, the reference line being a line corresponding to the gaze position; calculating a distance in the second direction between the reference line and the input coordinate as an offset amount with respect to the gaze position in a first screen predetermined direction along the screen; and calculating, as a display position of the pointer to be displayed on the screen, a position in which a distance in the first screen predetermined direction between the position and the gaze position is the offset amount on the screen. - View Dependent Claims (39)
