The number of public equipment by which users and operators can communicate through video connection over long distances has increased along with the development of Internet technology. However, this remote communication function was not easy to use and required personnel near the machine to assist the user. Since inexperienced users will use the equipment, usability becomes an important design factor. For this, designers often rely on design framework of usability, which consists of general principles and detailed guidelines and is based on international standards and de facto standards. However, there was no design framework of usability for remote communications. Based on principles and guidelines for remote communications which the authors constructed, this paper proposes a design matrix and examines its practicality.
