Hot topics-eye-gaze computer interfaces: what you look at is what you get

As computers are becoming more powerful, the critical bottleneck in their use is often in the user interface, not in the computer processing. Research in human-computer interaction that seeks to increase the communication bandwidth between the user and the machine by using input from the user's eye movement is discussed. The speed potential, processing stages, interaction techniques, and problems associated with these eye-gaze interfaces are described.<
