Abstract
The instrument is developped for the measurement of the speed and the accuracy in a target pointing motion. It consists of LED matrix board, a digitizer and a microcomputer.
It works as follows. By illuminating LED, LED matrix board indicates the target position to the subject. The subject is to point the position by a pen, an fast and correct as possible. The digitizer measures the pointed position. And the timer in the microcomputer calculates period of time between the moment LED illuminates and the moment the subject points the position. If the distance between the assigned position and pointed position is within the given allowance, the measuring process goes on. Otherwise the subject must repeat the same positioning.
This instrument is expected to determine the proper size and position of the Kanji-characters on the Kanji-input device.
