Wearable Haptics for Human Guidance in Structured and Unstructured Environments

In real world scenarios, visual and auditory channels may be overloaded with a huge quantity of stimuli resulting in some cases inefficacious or unusable. A possible solution is to provide information exploiting an underutilized sense, i.e., the sense of touch. As the sound, a tactile stimulus consist in a signal with varying frequency and amplitude. Differently from the auditory feedback, tactile sensation directly engages our motor learning system with extraordinary sensitivity and speed. Moreover, tactile communication can be used in situations where visual or auditory stimuli are distracting, impractical or unsafe. In this abstract, we report our main results showing the capability of wearable haptics interfaces to guide human in structured and unstructured environments.
