Abstract
We focuses on the trajectory of eyes and hands of the student movement for the engineering experiments, we propose an assessment method of the engineering experiments skill. Then, we constructs a simple skill assessment system using the infrared equipments and microcomputers. This system detects the movement of eyes and hands by infrared LED and an infrared sensor, and records the trajectory data in tablet PC via microcomputer. The skill assessment score obtain by using these data. We verified the validity of assessment method, and the simple skill assessment system by experiments.
