Experimental Research on Handwritten Character Written in the Air Recognition Based on Computer Vision
For the importance and complexity of handwritten character input in human-computer interaction system, a non-touch character input method has been proposed. A person holding light pen writes in the air in this method, the video of visual light spot movement in air is recorded by a camera and processed utilizing computer vision technology, then the handwritten character image is reconstructed, finally, the reconstructed character is recognized. The algorithm of light spot detection and character image recovery is given, and their effectivity has been verified experimently in this paper.
