In this research we propose a new motion classification method to improve operability of a 3D gesture interface that assists text input on mobile devices. A certain range of time-series finger scale data is cropped and is classified using linear discriminant analysis. To confirm possibility of linear separation, data were visualized using principle component analysis. Experimental result with changing...
In this paper, we propose an interface in which a camera detects the finger depth, and images and buttons are zoomed in/out based on the information. To stabilize images during operation, an image before zooming is translated so that the displayed image does not move in case of the same zoom ratio. The zoom ratio is kept unchanged at the ratio more than a certain level so that the image is not further...
