Claim 0:
1. A method for performing interactive operation upon a stereoscopic image, comprising:
displaying, based on stereoscopic image data, the stereoscopic image by a stereoscopic image display; wherein the stereoscopic image is a floating stereoscopic image that is formed by projecting an integrated image displayed on a flat display panel to a space at a distance from the flat display panel through a lens array, and the integrated image is rendered by multiple unit images which are one-by-one imaged through corresponding lenses of the lens array;
sensing a gesture that is performed on the floating stereoscopic image by a gesture sensor so as to obtain a current gesture state, wherein the gesture sensor is used to obtain an image and a depth map of a body part or a pointing device that performs the gesture;
calculating stereo coordinates of multiple critical positions of the gesture according to the image and the depth map;
obtaining a previous state of the stereoscopic image;
obtaining a previous gesture state;
calculating, according to the current gesture state and the previous gesture state, stereo coordinate variations corresponding to the gesture;
obtaining, according to the previous state of the stereoscopic image and the stereo coordinate variations corresponding to the gesture, new stereoscopic image data; and
displaying, by the stereoscopic image display, a new stereoscopic image rendered from the new stereoscopic image data;
wherein the gesture sensor obtains depth information of the gesture by a time of a flight detection technology, an acoustic detection technology, a binocular parallax detection technology, or a structured light detection technology, so as to form the depth map.
