Japanese Patent JP6540691
Kind Code:
B2
Abstract:
[Object] To readily detect a position of a head of a user using an inexpensive sensor. [Solution] Change of the position of the head accompanied by viewpoint movement of the sitting user is accompanied by rotation movement of the head. Therefore, posture of the head of the user is obtained by integrating angular velocity detected by a gyro sensor worn on the head, and the posture of the head of the user is converted into a position of a head on a user coordinate system assuming that the head moves on a spherical surface having a radius of an arm length r around a waist position of the user. By adding the obtained change of the position in a head coordinate system to a position in a camera set at an application side which renders an image, motion parallax is presented.
