Development of a Tele-Oral Test Hardware System Using Video Equipments and its Evaluation

Abstract

In an employment exam, students take the oral test. As for the oral test training, assuming that a trainee and the trainer as interviewer are separate by a long distance, here we discuss a distant training method of the oral test using a video camera and a TV monitor. We call it a tele-oral test training. In order that their eyes meet through the TV monitor, we propose a sophisticated hardware system using a half-mirror between a TV monitor and the trainer (and the trainee). We compare three kinds of the distant training hardware system: with a half-mirror, without a half-mirror, and telephones. As a result, the system with a half-mirror gets the highest utility. It was also obtained that the utility was about 90 percent of that in the direct face-to-face oral test method.
