In this paper, we propose an air-touch interaction system for the tabletop type integral imaging 3D display. This system consists of the real 3D image generation system based on integral imaging technique and the interaction device using a real-time finger detection interface. In this system, we used multi-layer B-spline surface approximation to detect the fingertip and gesture easily in less than 10cm height from the screen via input the hand image. The proposed system can be used in effective human computer interaction method for the tabletop type 3D display.
We propose the fusion between two concepts that are very successful in the area of 3D imaging and sensing. Kinect technology permits the registration, in real time, but with low resolution, of accurate depth maps of big, opaque, diffusing 3D scenes. Our proposal consists on transforming the sampled depth map, provided by the Kinect technology, into an array of microimages whose position; pitch and resolution are in good accordance with the characteristics of an integral- imaging monitor. By projecting this information onto such monitor we are able to produce 3D images with continuous perspective and full parallax.
