Vidya Setlur: Research Description Optimizing Computer Imagery for Communication

Computers are becoming faster, smaller and more interconnected, creating a shift in their primary function from computation to communication. This trend is exemplified by phenomena such as cellular phones with cameras, personal digital assistants with video, information displays in automobiles, and computer screens in elevators and refrigerators. As communication devices and viewing situations become more plentiful, we need imagery that facilitates visual communication across a wide range of display devices. In addition, producing effective and expressive visual content currently requires considerable artistic skill and can consume days. The goal of my research is to develop new techniques and user interfaces that enhance visual communication, while making it fast and easy to generate compelling content. My research combines concepts and methods from visual art, perceptual psychology, information processing, and cognitive science to facilitate users in creating, understanding and interpreting computer imagery. I am currently conducting research in the following areas:
