Tactile Language for a Head-Mounted Sensory Augmentation Device

Sensory augmentation is one of the most exciting domains for research in human-machine biohybridicity. The current paper presents the design of a 2nd generation vibrotactile helmet as a sensory augmentation prototype that is being developed to help users to navigate in low visibility environments. The paper outlines a study in which the user navigates along a virtual wall whilst the position and orientation of the user's head is tracked by a motion capture system. Vibrotactile feedback is presented according to the user's distance from the virtual wall and their head orientation. The research builds on our previous work by developing a simplified "tactile language" for communicating navigation commands. A key goal is to identify language tokens suitable to a head-mounted tactile interface that are maximally informative, minimize information overload, intuitive, and that have the potential to become 'experientially transparent'
