Eye-gaze control of multimedia systems

It is suggested that interest and emotion sensitive media hold great potential for information systems in general—for example, information stands and interactive television.

Abstract

This chapter describes the eye-gaze control of multimedia systems. Several non-intrusive systems for recording eye movements, gaze locations, pupil size, and blink frequencies have been introduced in recent years. The application of this technology falls into two main categories: (1) active device control, and (2) passive recordings. Active device control means the voluntary use of gaze positioning to do selections. Traditionally, passive recordings of the user's ocular behavior have been made for different analyses—for example, human–computer interaction or newspaper reading. The chapter also describes a multimedia system that applies both types of recordings separately and introduces a qualitatively new interaction principle, termed “interest and emotion sensitive” media (IES), that emerges when the two types are integrated. It is suggested that interest and emotion sensitive media hold great potential for information systems in general—for example, information stands and interactive television.
