One measure of HCI research activities is publication in the annual Human Factors in Computing Systems Conference (CHI). Table 2.2 lists all the publications of researchers from Japan since 1990. The majority of these papers are systems-oriented, most notably in the area of graphics and video, and almost 80% of the work is from industrial research labs. CHI publication statistics for Japan, Europe and North America are summarized in Figure 2.1.
