A new multi-sensor strategy aimed to assist blind people in performing mobility tasks is proposed. The device is based on arrays of IR sensors and uses a threshold strategy to produce very reliable information on the target position. Low-cost feature is also achieved. The signal processing is performed by adopting non-linear paradigm running on a micro-controller. Experimental evidence of the device performance is given.
