Virtual object movement in response to real object movement

摘要

An entertainment device (10) receives images from a video camera (756), and combines the images captured by the camera with a computer-generated image of a virtual object 3010 resting on a virtual surface 1010 so as to generate a composite image. The device comprises detecting means that detects image movement in the captured images in one or more contact point regions 3020a corresponding to image positions at which the object contacts the virtual surface, and initiating means that initiates movement of the object to a new position 3120 with respect to the virtual surface in response to detected motion in the contact point regions of the captured images. The motion in the captured image may be from the captured image of the user's hand 3100. The virtual object may be a virtual pet and it may also have interaction regions (3050, 3060) to initiate a game action when motion in the interaction regions is detected.
