Multi-sensory Environmental Stimulation for Users with Multiple Disabilities

Multi-sensory environments can improve and maximize the well-being of individuals with multiple disabilities, that is, individuals who have more than one significant disability (one of which is a cognitive impairment). In this chapter we present a multi-sensory environmental stimulation system that combines different technologies such as computer vision and tactile cues in the form of vibrations. The system offers users control over the environmental stimulation by responding to their body movements. A vision-based interface detects the user’s hand position and activates meaningful and motivational outcomes when the hand is positioned over specific regions. Further, we extended the system by including a wearable vibrotactile interface that encourages users to move their arms by using vibrations that exploit the saltation perceptual illusion known for inducing movement.
