This paper describes the development of an indoor vibrotactile navigation system for the visually impaired people. We aimed at realizing a wearable, low-cost, and effective system able to help blind users in unknown indoor environments that they might visit occasionally, such as hospitals, airports, museums, etc. The designed system implements a Bluetooth (BT) localization service, and provides wayfinding cues to the user by means of a wearable device equipped with five motors. The last part of our work describes early results obtained by the use of electroencephalographic (EEG) analysis to evaluate the vibrotactile feedback.

Abstract
This paper describes the development of an indoor vibrotactile navigation system for the visually impaired people. We aimed at realizing a wearable, low-cost, and effective system able to help blind users in unknown indoor environments that they might visit occasionally, such as hospitals, airports, museums, etc. The designed system implements a Bluetooth (BT) localization service, and provides wayfinding cues to the user by means of a wearable device equipped with five motors. The last part of our work describes early results obtained by the use of electroencephalographic (EEG) analysis to evaluate the vibrotactile feedback.File in questo prodotto:
