There is little extistent literature that has investigated the process involved in writing Japanese two-morpheme (kanji) compound words. One reason for this scarcity has been the difficulty in devising instruments to measure latencies for writing behaviour. To asnwere this problem, we developed software that enabled us to present auditory stimuli, to measure writing latencies, to track trajectories during the writing of kanji characters, and to assist data analysis. This software runs on the Microsoft Windows 98 Operating System with a commercially available pen-tablet. Technical details of this software will be explained in this paper.
