A Comparison of Haptic Transmission Methods and Influences of Network Latency in a Remote Haptic Control System

Abstract

This paper makes a comparison between two-way transmission and one-way transmission of the sense of force in terms of easiness of work in a remote haptic control system by subjective assessment. In the system which is applied to an instruction system, a teacher teaches a student how to write characters. We have two cases about how to attach a pen and how to transmit video. In one case, a pen is attached to only the student's terminal, and video is transmitted from the student's terminal to the teacher's terminal. In the other case, a pen is attached to each of the two terminals, and video is transmitted bi-directionally between the terminals. In both cases, we also investigate the influences of network latency on the easiness of work.
