Abstract: A photographed image acquisition unit 212 acquires an image obtained by photographing a device. 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. A stationary determination unit 234 determines whether or not the device is stationary on the basis of the sensor data. When it is determined that the user is not touching the device and the device is stationary, the estimation processing unit 230 fixes the estimated position of the device.

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: 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: Disclosed herein is an information processing apparatus including a first device information acquisition section that acquires position and posture information relating to a first device worn on a user, a second device information acquisition section that acquires position information relating to a second device worn on a portion different from the first device on the basis of the position and posture information relating to the first device and a skeleton model of a human, and a sensor data acquisition section that acquires sensor data from a sensor that measures motions of the first device and the second device. The second device information acquisition section changes a degree of following of the skeleton model to the first device on a basis of the sensor data.

Abstract: An information processing apparatus includes a captured image acquisition unit that acquires an image captured by imaging a device including plural markers. A marker image coordinate specification unit specifies a representative coordinate of each marker image from the captured image, and a position and posture derivation unit derives position information and posture information of the device using the representative coordinates of the marker images. The marker image coordinate specification unit specifies a first boundary box surrounding a region within which pixels having a first luminance or more continuously appear, specifies a second boundary box surrounding a region within which pixels having a second luminance or more continuously appear in the first boundary box, the second luminance being higher than the first luminance, and derives a representative coordinate of each marker image based on pixels in the first or second boundary box in response to the number of specified second boundary boxes.

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 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.
