A method for user interaction when gaming. The method including rendering a normal view of a virtual environment of a video game for display in an HMD of a user. The method including detecting a pose of a user holding a first controller and a second controller indicating that a virtual weapon is being held. The method including detecting that the pose of the user is raised to a firing position. The method including detecting that the pose of the user is in alignment with a face of the user. The method including detecting that a first eye of the user is closed. The method including detecting an object in the virtual environment being targeted by the pose that is in alignment with the face of the user. The method including rendering a magnified view of the object being targeted in the virtual environment for display in the HMD.

Provided are a skeleton model updating apparatus, a skeleton model updating method, and a program by which time and effort for changing the pose of a skeleton model to a known standard pose can be reduced. A target node identifying section (80) identifies a plurality of target nodes from among a plurality of nodes included in a skeleton model that is in a pose other than a known standard pose. A reference node identifying section (82) identifies a reference node that is positioned closest to the side of the plurality of target nodes, from among nodes that are connected to all of the target nodes via one or more bones. A position deciding section (84) decides positions of the plurality of target nodes such that relative positions of the plurality of target nodes with respect to the position of the reference node are adjusted to predetermined positions. A pose updating section (56) updates the pose of the skeleton model to the known standard pose on the basis of the decided positions of the target nodes.

Methods and apparatus provide for acquiring, from a plurality of sensors attached to a plurality of body parts of a target person, at least information regarding movement acceleration and posture angular velocity of each of body parts to which the sensors are attached, and estimating, on the basis of the acquired information regarding the movement acceleration and posture angular velocity, the movement velocity in a predetermined coordinate system of each of the body parts to which the sensors are attached. Subsequently, on the basis of the information regarding the estimated movement velocity of each of the body parts, the methods and apparatus provide for estimating the positions of predetermined body parts of the target person.

The present invention is configured so that a player and a third party other than the player can enjoy a game. A server 4 comprises a game execution unit 51, a behavior information acquisition unit 53, and a reflection unit 54. The game execution unit 51 executes a game in which an object is caused to act in accordance with the movements of a player P. The behavior information acquisition unit 53 acquires behavior information pertaining to the behavior of a third party related to the game other than the player P. The reflection unit 54 generates changes that affect the game, including the object, on the basis of the behavior information.

A light field (LF) display system implements a holographic video game. The LF display system includes an LF display assembly that displays holographic game content. The LF display system can also include a sensory feedback assembly that provides tactile feedback to users by projecting an ultrasonic wave, a tracking system that can track one or more body parts of a user, and a controller that executes a game application and generates display instructions for the LF display assembly. The LF display system can implement an interactive video game that tracks a body part of a player and provides both visual and haptic feedback to the player to depict an in-game interaction, such as an explosion or impact. The video game may be implemented as part of an LF gaming network.

A virtual reality training system according to an aspect of the invention may include a floor system having a base of a particular length and width, an object member configured to be detachably installed on the floor system, an input unit configured to assign a first position, which corresponds to the position of an object within a virtual reality space having a length and width smaller than or equal to the length and width of the base of the floor system, and a mapping unit configured to compute and output a second position, for installing the object member on the floor system, computed as a position on the floor system corresponding to the first position within the virtual reality space.

A board game system comprises a game board, having a surface adapted to receive a board game overlay, a detector array adapted to detect the respective positions of a plurality of game pieces placed on top of the board game overlay, and a transmitter adapted to transmit data indicating the respective positions to an entertainment device; and an entertainment device, having a receiver adapted to receive from the game board data indicating the respective positions of the plurality of game pieces, a game state analyser operable to update the state of a game in dependence upon the indicated respective positions of the plurality of game pieces, and an image generator operable to generate an image for output to a display, the content of the image being responsive to the detected state of the game.

Disclosed is a system (100, 200) for giving feedback based on motion before or during medical imaging, comprising: —an optical camera device (110, 210) that is configured to generate image data of at least two images of a subject (408) or of a part of a subject (408) which can be arranged or is arranged at a subject placing location (194) of a medical imaging device (192), and—a feedback signaling unit (120, 124) that is configured to generate based on movement data obtainable from the image data a feedback signal (Si1, Si2) that is perceptible by the subject (408) and/or by an operator of a medical imaging device or by MRI technician (192).
