The aim of this study is to implement human-harmonized information presentation technology based on the premise that it will be used in gathering places frequented by large numbers of people. This technology will be geared toward facilitating face-to-face communication while superimposing a world of information on the real world. We call this sort of technology a Harmonized Inter-Personal Display.
In places that are frequented by large numbers of people, it is desirable to be able to access information while maintaining eye contact with other people and the surrounding objects. If everyone sharing a space is not only provided with a constant and consistent flow of information but can also be sent information tailored for each user according to their location and orientation, then this space can be made more friendly. Hitherto, superposition techniques (augmented reality) have mainly been used within the information terminal displays of individual users.
In this study, we go beyond this framework by embedding information in light and sound which is presented to users while controlling the locality and directionality for the real world, thereby allowing people to freely access information that is spread out spatially rather than being held within the confines of a display screen.
