Perceptive three dimensional interface via stereo observation

Abstract

This paper describes an intuitive approach for interacting with a computer or computer-driven applications. Interaction is achieved by observing, through a stereo camera set-up, the motion of a user's hands. This motion is then translated into 3-dimensional (3-D) coordinates to enable interaction with either a traditional 2-dimensional (2-D) desktop or a novel 3-D user interface. The aim of this work is to provide an intuitive method of interaction to computer based applications for individuals whose condition might restrict their ability to use a standard keyboard/mouse.

“…When using color thresholding, it is important to determine the optimal range of the threshold values to minimize segmentation errors [29,[31][32][33]. Narrowing the thresholds increases the probability that the accepted pixels are actually part of the object of interest, though it can also result in rejection of numerous actual pixels that represent that object.…”
