Multimodal vision glove for touchscreens

This paper presents the development of an inexpensive haptic glove enabling people with visual impairments to picture and interact with basic algebra graphs through multiple points of interaction on touchscreens. The glove sends vibrations to each finger representing a direction which the user must follow to reach a graph on a grid. Through repeated movement, a person will reach, trace, and visualize the graph. Evaluations by thirteen students with visual impairments indicated that visualizing a graph, using multiple points of interaction with haptic feedback, is much faster than single-point-interaction with audio feedback.
