A study on natural movement of artificial eye implant

A person with one eye missing, due to various causes, may suffer psychologi cally as well as physically. The lost eye can be mechanically replaced by a n ocular implant. Significant advances have been made in this area. An ocul ar prosthesis was created to replace the lost eye. The prosthesis appears n atural physically. However, the eye is static or has small movement ability . The purpose of this paper is to develop an autonomous ocular motor system , so the artificial eye can have more natural movement. Detection of moveme nt of the natural eye is an important issue. A review of eye movement detec tion methods is included in this paper. Then fusion method is designed for eye movement detection. First the eye movement is recorded and stored as se nsed data space. Then during the experiment, the eye movement signal is obt ained through the sensor array and through the matching rule, the eye posit ion is obtained. The main part of this paper deals with the experimental sy stem, fusion technologies, and preliminary results. (C) 2000 Elsevier Scien ce B.V. All rights reserved.
