Augmented non-visual distance sensing with the EyeCane

Abstract

How can we sense distant objects without vision? Vision is the main distal sense used by humans, thus impairing distance and spatial perception for sighted individuals in the dark or for people with visual impairments. We suggest augmenting distance perception via other senses such as using auditory or haptic cues, and have created the EyeCane for this purpose. The EyeCane is a minimal Sensory Substitution Device that enables users to perform tasks such as distance estimation, and obstacle detection and avoidance up to 5m away on-visually. In the demonstration, visitors will receive a brief training with the device, and then use it to detect objects and estimate distances while blindfolded.
