Blind or visually impaired persons may experience challenges forming a mental map of the world around them. Our goal, in this participatory study, was to bridge the gap found in current technologies for a blind woman by creating a model utilizing tactile feedback. To achieve this goal, we designed three prototype sensory substitution systems. These prototypes attempted to aid our participant in crafting a world around her by providing auditory or tactile feedback in accordance to her proximity to an object. Each used a different form of output for the user: audio, vibration, or pressure. All of the stimuli produced by the models was managed by a researcher in place of a computer-vision algorithm. From our participant's feedback, we hope to develop a device that will provide the user a physical sensory substitution experience of sight.
