Snapshots of players making correct tetrominos are tweeted, and this feed is used by a mobile and web-based Tetris game, which can be played from anywhere in real-time.

ShadowGuides provides on-demand assistance to the user by combining visualizations of the user"s current hand posture as interpreted by the system (feedback) and available postures and completion paths necessary to finish the gesture (feedforward). Our experiment compared participants learning gestures with ShadowGuides to those learning with video-based instruction. We found that participants learning with ShadowGuides remembered more gestures and expressed significantly higher preference for the help system.

A) user points Kinect at coffee table scene. B) Phong shaded reconstructed 3D model (the wireframe frustum shows current tracked 3D pose of Kinect). C) 3D model texture mapped using Kinect RGB data with real-time particles simulated on the 3D model as reconstruction occurs. D) Multi-touch interactions performed on any reconstructed surface. E) Real-time segmentation and 3D tracking of a physical object. ABSTRACT KinectFusion enables a user holding and moving a standard Kinect camera to rapidly create detailed 3D reconstructions of an indoor scene. Only the depth data from Kinect is used to track the 3D pose of the sensor and reconstruct, geometrically precise, 3D models of the physical scene in real-time.

But how is interaction altered by the absence of a physical input device? What is the impact on game performance, on a player's expectation of their ability to control the game, and on their game experience? In this study, we investigate these issues in the context of a table tennis video game. The results show that the impact of holding a physical controller, or indeed of the fidelity of that controller, does not appear in simple measures of performance. Rather, the difference between controllers is a function of the responsiveness of the game being controlled, as well as other factors to do with expectations, real world game experience and social context.
