Computer Analysis of ENG by an All-purpose Software Program System

We tested the applicability of all-purpose software to programs of analyzing ENG and found it as useful as custom-made programs in the following aspects : 1. artifact elimination ; 2. number analysis of the nystagmus ; 3. measurement of the velocity and amplitude of the slow-phase ; 4. determination of the fast-phase velocity ; 5. demonstration of eyemovements in relation to the movement of the gaze target in the ETT test. Although some problems such as on-line processing are left unsolved, this system of analysis assures cost effectiveness and adjustability for each researcher's purposes. It is a valuable resaerch tool.
