Interactive stereoscopic display and interactive sensing method for the same

An interactive stereoscopic display, comprising:

• a stereoscopic image display, which has a flat display panel, used to display a floating stereoscopic image that is projected to a space at a distance from the flat display panel through a lens array according to stereoscopic image data, wherein the flat display panel displays multiple unit images that construct the floating stereoscopic image through the lens array and each of the unit images displayed on the flat display panel is imaged through a corresponding lens;
• and
• a gesture sensor, sensing a gesture which is performed by a user's hand for performing an interaction upon the projected floating stereoscopic image so as to form stereo coordinate variations in response to the gesture, wherein, after continuously acquiring stereo coordinates of the gesture, the stereo coordinate variations are obtained;
• wherein, in the stereoscopic image display, the stereo coordinate variations are obtained, an interactive instruction is determined according to the stereo coordinate variations in order to generate new stereoscopic image data by comparing a previous state of image coordinate data with image coordinate data of the floating stereoscopic image, and display a new floating stereoscopic image using the new stereoscopic image data which is obtained by querying an image database or being calculated instantly according to the interactive instruction;
• wherein the interactive instruction indicative of moving, rotating and/or zooming actions is calculated by an image processor when receiving the stereo coordinate variations corresponding to the gesture.
