We have developed a system that helps users acquire historical viewpoints using a wearable computer. This is accomplished by overlaying incidents from the past and live scenes from the present on a see-through display. The purpose of this system is to enable history learners to combine past and present information and obtain significant notion of the continuity of time through viewing part of the series of events which happened in that very place. In evaluating this system, we found out that users could experience and feel history as a reality. We contend that this system is effective in furthering the motivation of history learners, and we have an expectation that can become a significant new educational media.
