This paper proposes the results of a user study on vision-based depth-sensitive input system for performing typical desktop tasks through arm gestures. We have developed a vision-based HCI prototype to be used for our comprehensive usability study. Using the Kinect 3D camera and OpenNI software library we implemented our system with high stability and(More)

Visual presentation of a talking person requires the generation of image frames showing the speaker in various views while pronouncing various phonemes. The existing approaches, mo stly use either a complex 3D geometric model to reconstruct a desired image or a set of 2D images for each viewpoint, to select from. We propose a new system which utilizes(More)
—This paper proposes FML, an XML-based face modeling and animation language. FML provides a structured content description method for multimedia presentations based on face animation. The language can be used as direct input to compatible players, or be compiled within MPEG-4 XMT framework to create MPEG-4 presentations. The language allows parallel and(More)
