Abstract

Many tasks may be performed with greater efficiency and speed with hapticas sistance. Using the Penbased Haptic Display, a low-power, low-friction, and high-precision device, we performed two separate experiments to measure two properties of human/haptic interactions. In the first ex-periment, we measured the level of force at which a subject may detect the presence of haptic feedback at a 71 accuracy level using a converging adaptive threshold algorithm. The average haptic threshold of eleven subjects was 20.8 milliNewtons. The second experiment quantifies changes in task performance using Fitts Law. We measured improve-ments at three force levels compared to no force.
