enhancing vr-based visualization with a 2d vibrotactile array
We discuss methods to enable haptic visualization on vibrotactile arrays. Our work is motivated by the potential for a tactile array to provide an additional useful channel for information such as location cues related to dataset features or remote user behaviors. We present a framework for array rendering and several specific techniques. Novel aspects of our work include the example application of a palm-sized tactile array to visualize dataset features or remote user state in a VR system, a generalized haptic glyph mechanism for 2D tactile arrays, and the extension of graphical visualization techniques to haptics (glyphs, fisheye distortion, spatial anti-aliasing, gamma correction).
