Indoor navigation based on RFID tags: orientation possibilities for visually impaired

Visually impaired people still have difficulties to independent movement in indoor and outdoor environments. In outdoor environments, GPS capability can be used to support orientation. However, the mobility of these users indoors is still a challenge. Advances in technology, emphasizing the contribution of research in Human-Computer Interaction, allow the development of accessible solutions that provide greater independence, security and improvement of life for the visually impaired. In this context, this paper presents the development of a solution to help guiding blind people indoors. This solution makes use of embedded systems low cost, RFID technologies, and mobile devices.
