Abstract

A finger-worn haptic device capable of rendering 2-D graphics through vibrotactile feedback is presented. The device development is presented from its initial stages of being a stylus design using a photo-interrupter optical sensor and pager-motor actuator to a small case worn on the finger using a RGB color sensor and a piezoelectric actuator. Testing of the latest prototype design shows that it has a spatial sensitivity (<2mm) comparable to natural touch (~1mm) and can be used to output a variety of vibrotactile textures. The design can be expanded for a multiple finger, independent device, while remaining affordable (<$100) and highly portable (<500g).
