The purpose of this study is (1) to provide information about three-site multipoint distance learning utilizing the high-definition “HyperMirror” and (2) to determine how the video image quality of standard definition and high definition affect distance learning. We carried out distance learning projects twice in 2010, on (a) January 28th [Standard Definition] and (b) February 24th [High Definition], with middle schools in Nara and Kumamoto and the High Energy Accelerator Research Organization, Tsukuba in Japan. The three locations successfully connected using HyperMirror during the projects. Afterwards, a questionnaire survey revealed that image quality was not the sole contributing factor in the overall assessment of HyperMirror. However, it was suggested that easy-to-see figures, pictures, and remote students’ facial expressions were important for students.

We have developed a distance education system for developing skills in endoscopic paranasal sinus surgery, to enable efficient remote training of novices in manual skills such as their standing position and posture, and the insertion angle/depth and holding of surgical instruments. The system uses a precise model of human paranasal sinuses and the HyperMirror (HM) telecommunication interface. HM is a virtual mirror allowing clear visualization of differences in manual operation between the trainee and remote expert. This paper outlines the proposed system and describes remote training experiments between two locations 200 miles apart. In the experiments, two expert surgeons trained 17 novices for 40 to 60 min on probing of the nasofrontal duct and aspiration of the maxillary sinus, and subjectively evaluated their manual skills. The results showed that most of the novices improved their manual skills and were able to complete each procedure.

In counseling, non-verbal communication such as making physical contacts is an effective skill of role playing. In remote counseling via videophones, spacing and physical contacts cannot be used, and communication must be made only with expressions and words. This paper describes an embrace system for remote counseling, which consists of HyperMirror and vibrators and can provide effects similar to those by physical contacts in face-to-face counseling.
