||Communicating is an impossible mission for disables who have normal function eyes and is conscious, but can’t express normally. If there exists a new communicating interface, in a situation of users express function loss completely, it could transmit his will clear. It is utmost help for the outside communicating to disables and patients’’ condition understanding.|
Our research objective is constructing a unit of “Symbols Expression System Based On Eye Movement”, that is a system that utilize particular eye movement locus to express particular symbols. By sensing week potential around eye to be aware of the direction of eye movement and using software analysis technology to judge the users express symbols.
In my thesis, I utilize Electro-OculoGraphy (EOG) to be the method of acquiring eye movement signal. Using the eye shaking direction, the number of times and correlation as the input characteristic value of the Learning Vector Quantization (LVQ) Neural Network, depend it judging the symbols draw by user. In the system, there are fourteen kinds of symbols for use, hence, it could allow user to express different mean.
