In this project, we investigated different methods to reproduce real surfaces on friction modulation displays. We modulated the friction force between a fingertip and the display using electrostatic forces. We investigated both data-based (record and play) and model-based (generate groove and ridges) techniques. We also tested the realism of the generated virtual textures via psychophysical experiments.
Keywords: texture, electrovibration, electrostatic friction modulation displays, realistic
