Trends in Research and Development of CAI Hardware in Japan

Abstract

This paper reviews research and development of CAI hardware in Japan since 1977. The trends in this field can be summarized into three major categories : 1. Development of practical CAI systems. 2. Improvements in man-machine interfacing and CAI functions. 3. Development of microcomputer and stand-alone CAI systems. All three trends are a result of the development of low-cost and highly functional microcomputers. Prior to 1976, the purpose of CAI research was usually to develop special-use CAI terminals for presenting the Japanese language (kanji and kana) or graphics. Since then, however, standard TSS terminals or microcomputers have been used as CAI terminals. This is primarily because these newer terminals are capable of a great variety of functions. However, not all hardware problems have been resolved. Inputting Japanese and high cost, as well as courseware compatibility, etc., are still barriers to the development of CAI. New problems resulting from the use of stand-alone classroom CAI systems in are how to quickly and efficiently distribute courseware and gather student responses. At the end of his report, the author proposes a list of functions which he considers desirable of any CAI hardware system.
