Abstract: An improvement in accuracy in recognition of the position and posture of input devices is achieved. The input device has a grip extending in an up-down direction, an upper portion positioned upward of the grip and having operating members to be operated by a finger disposed therein, and a lower portion positioned downward of the grip and having a plurality of to-be-tracked points disposed therein. The width of the lower portion is greater than the width of the grip. This makes it easier to dispose a large number of to-be-tracked points in the lower portion.

Abstract: An input device includes a case body and a plurality of markers 30d, 30e, and 30p configured to emit light to the outside of the case body. When an angle difference between the normal directions of the two markers 30d and 30e is less than a predetermined threshold value, a distance between the two markers 30d and 30e is equal to or greater than a predetermined first distance. When an angle difference between the normal directions of the two markers 30d and 30p is equal to or greater than a predetermined threshold value, a distance between the two markers 30d and 30p is equal to or greater than a predetermined second distance, and the second distance is shorter than the first distance.

Abstract: An information processing apparatus includes a captured image acquisition unit configured to acquire an image captured by imaging a device that includes a plurality of markers, and an estimation processing unit configured to estimate position information and posture information of the device on the basis of a marker image coordinate in the captured image. The estimation processing unit includes an extraction unit configured to extract N marker image coordinates in the captured image, N being an integer equal to or greater than three, and a position and posture derivation unit configured to derive the position information and the posture information of the device from the extracted N marker image coordinates and three-dimensional coordinates of N markers in a three-dimensional model of the device. The extraction unit extracts, where selected N+A marker image coordinates have a predetermined positional relation, N marker image coordinates from among the N+A marker image coordinates, A being an integer equal to or greater than one.
