A Low Resolution Haptic Interface for Interactive Applications.

This paper introduces a novel haptic interface for use as a general-purpose sensory substitution device called the Low Resolution Haptic Interface (LRHI). A prototype of the LRHI was developed and tested in a user study for its effectiveness in conveying information through the sense of touch as well as for use in interactive applications. Results are promising, showing that participants were able to accurately discriminate a range of both static and dynamic haptic patterns using the LRHI with a composite accuracy of 98.38%. The user study also showed that participants were able to sucessfully learn to play a completely haptic interactive cat-mouse game with the device.
