In recent years, increasing productivity has become an urgent task for Japanese businesses as the labor force contracts due to the low birth rate and aging population. Japan has now directed its focus on the introduction of IT in businesses as a solution, as well as the effects of its introduction. Therefore, this study conducted an experiment in which tablet terminals—a form of IT—were used for sorting work— an intellectual task—and trends in work times and variations therein were examined using the achievement rate method, a method for evaluating work learning. The results indicated that the use of tablet terminals enables consistent sorting of work with little variation in work times, regardless of differences in workers or the number of days worked. It was also found that the tool produces temporary visual fatigue; although it leads to increased productivity, it also has a physical effect on workers.
