Abstract

We are conducting a research project aimed at building an information secured environment for the visually impaired, especially in our campus, by combining data-carrier technology and networks. We use RFID tags and networks to keep the environmental information and to trace the changes in the environment. Our approach is the following: 1. In the mental map kept by the visually impaired person landmarks play a significant role, 2. We can turn any object (location) in the surroundings into a landmark by attaching an RFID tag to it, 3. The changes in the environment could be recognized, at least roughly, by recognizing changes of landmarks. We outline two methods to trace the changes of locations of RFID tags in the environment. The first one is to detect the moves of active RFID tags directly by analyzing the signals emitted from them. The second one is to trace the moves of passive RFID-tags by autonomous cruising robots. In both cases the changes are kept and updated in the network, and then conveyed to a visually impaired person according to his inquiry.
