Abstract

An experiment of comparing presentation tools for a computer laboratory using a usability test is shown. We compared the cognitive effects of presentation tools, a video projector, and an inter-PC screen broadcasting system, in a computer laboratory. We have quantitative results of the presentation tools' cognitive effects on users. The results of the experimental measurements were that the projector was better if there was a small amount of data on one screen and the screen broadcasting system was better if there was a large amount of data on one screen.
