Toward Vibrotactile Rendering for Irregular 2D Tactor Arrays

We motivate further study of vibrotactile rendering schemes for the sensation of arbitrary points in irregular grids or meshes, outline a conceptual approach, and propose a study for assessing and comparing approaches. A conceptual model presents the combination of vibrations from multiple elements (tactors) as a two-stage pairing of tactors into virtual tactors, considering the 2D dimensionality. To support irregular triangle meshes, we suggest parameters to characterize triangle shape and a future study to measure sensations for varying shape. Gathered data will be used to assess and compare perceptual combination models and to develop precise rendering functions for irregular triangle meshes.
