Perceiving Surface Roughness via a Rigid Probe: Effects of Exploration Speed and Mode of Touch
Two experiments investigated the psychophysical consequences for roughness perception of altering the speed of motion with which textured surfaces are explored using a rigid probe. Two speed ranges were used: a 10-fold change (Experiment 1) and a 4-fold change (Experiment 2). Relative motion was altered both by moving the ...
Design and Performance of a Tactile Shape Display Using RC Servomotors (Short Paper)
(Haptics-e, The electronic journal of haptics research, 2004-08-06)
Tactile displays are used to convey small-scale force and shape information to the fingertip. We describe a 6x6 tactile shape display design that is low in cost and easily constructed. It uses commercially available RC servomotors to actuate an array of mechanical pins. The pins deflect a maximum of 2mm. with a resolution of ...
