However, some of the handicapped, like severe amyotrophic lateral sclerosis (ALS) are difficult to communicate or control outside devices as healthy people, especially under the situations that the caretaker is not available. In this thesis, we measured the eye movements by electro-oculography (EOG). We used electrodes to measure the electrical potential difference between the skins above and below the eyes to know the eye movement. The signals are preliminary processed by outside circuit and then transmitted to the computer to be analyzed and recognized by Labview. After that, users can communicate with others by human-interface or the signals are transmitted to control circuits for outside devices control. This thesis proposes a set of eye-controlled system with low price and hope that this system could help the disabled whose eyes still function well, to do some simple and daily work by themselves and reduce the burden of their families.
