We explore the generation of interactive computer graphics at digital set-top boxes in place of the fixed graphics that were embedded to the television video before the broadcast. This direction raises new requirements for user interface development, since the graphics are merged with video at each set-top box dynamically, without the traditional quality control from the television producers. B...

Q1. What do you mean by computer graphics? Ans. The branch of science and technology concerned with methods and techniques for converting data to or from visual presentation using computers. Q3.What do you mean by interactive computer Graphics? Ans. Interactive computer Graphics like a website, it is only useful if it is browsed by a visitor and no two visitors are exactly alike. It means the w...

This is a report of some applications of human-machine systems and humancomputer interaction about experimental multimedia performing arts. The human performer and the computer systems perform computer graphics and computer music interactively in real-time. As the technical point of view, this paper is intended as an investigation of some special approaches: (1) real-time processing and communi...

Many applications, such as realistic rendering, virtual and augmented reality, and virtual studios, require an accurate simulation of real lens and camera systems at interactive rates, including depth of eld and geometric aberrations, in particular distortions. Unfortunately, camera models used in Computer Graphics are either too simple to describe these eeects or too expensive to simulate for ...

Currently, most of multi-touch surface tables do not provide any tactile feedback to the users. In this paper, a multi-touch surface table with tactile feedback is proposed. The proposed surface table provides the users with the ability of multi-point tactile feedback with variant patterns and levels of vibrations. A webcam is used to capture all finger-touch images as system inputs using compu...

The 18th International Conference on Computer Graphics and Interactive Techniques, SIGGRAPH'91, featured a juried selection of virtual reality and hypermedia demonstrations entitled Tomorrow's Realities. Conference participants were treated to twenty-six exhibits which represented the state of the art in virtual world techniques. The SIGGRAPH'91 Conference Proceedings (Computer Graphics, July 1...
