A sensor data acquisition unit 214 acquires sensor data indicating an acceleration and/or an angular speed of the device. An estimation processing unit 230 estimates a position of the device on the basis of the image obtained by photographing the device. A contact determination unit 232 determines whether or not a user is touching the device.

Abstract: A sensor data acquisition unit 214 acquires sensor data indicating an acceleration of a device including a vibrator. A second estimation processing unit 250 estimates a speed of the device on the basis of the sensor data. A vibration determination unit 262 determines whether or not the vibrator is vibrating on the basis of the sensor data. A stationary determination unit 264 determines whether or not the device is stationary on the basis of the sensor data. A second estimation processing unit 250 reduces the estimated speed of the device in a case where it is determined that the vibrator is vibrating and the device is stationary.

Abstract: Two light-emitting units are to be prevented from overlapping each other in an image obtained through a camera. A tracked unit (30) has a first outer surface (A1) provided with a first light-emitting unit (H1), a second outer surface (A2) provided with a second light-emitting unit (H2), and a light shield portion (B). The second outer surface (A2) faces a second direction different from that of the first outer surface (A1). The light shield portion (B) is located further outside than the first light-emitting unit (H1) and the second light-emitting unit (H2).

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 information processing apparatus acquires, using an image obtained by capturing a device including a light-emitting marker with exposure times shorter than a time corresponding to one frame, information regarding a position and a posture of the device. The light-emitting marker is caused to emit light for light emission times equal to or shorter than the exposure times. The information processing apparatus causes the light-emitting marker to emit light in a predetermined flashing pattern, and identifies the exposure times on a time axis of the device on the basis of whether or not the image appears in the captured image, to thereby synchronize the exposure and the light emission.
