Abstract
Today, persons with a visual impairment use a cane to explore their surroundings and sense objects in their vicinity. While electronic aids have been proposed to aid them, they communicate limited information or require a fixed position. We propose VibroVision, a vest that projects information about the area in front of the wearer onto her abdomen in the form of a two-dimensional tactile image rendered by an array of vibration motors. This vest enables the user to sense features such as shape, position, and distance of objects in front of her.
