A preliminary investigation of the information carrying potential of voluntary eye movements

This paper reports the preliminary findings of a study on the information carrying potential of voluntary eye movements. An ocular communication device, originally developed at the Denver Research Institute, was used to determine how fast information can be transmitted by voluntary eye movements. The tentative findings are that: a maximum information throughput of roughly 10 bits/s is possible and the DRI device merits further development. The primary relevance of this study is to the development of communication aids for the severely handicapped.
