Aimulet: Stoic Information Terminal for Location-Based User Supporting Systems

We have been developing specific guest guiding system based on compact battery-less information terminals, Aimulet. Implemented conventional Aimulet has features of location and direction sensitive information service device without batteries. On the other hand, the Annulet has two subjects, one is multi-lingual service and another is interactivity. These subjects are solved by using wavelength division multiplex technique and active RFID or/and reflectivity modulation. These techniques are applied to the EXPO 2005, Aichi Japan and other demonstrations.
