Abstract

In designing kinematic mechanisms such as haptics devices for human usability, we must carefully consider human motion range. However, size variation across the human population significantly complicates anthropocentric design analysis. In this paper we develop a probabilistic representation for mechanism reachable workspace which is based on a kinematic model containing stochastically defined parameters. Using anthropometric data, we show how this "stochastic reachable workspace" may be derived, and present a case study for the human finger. This representation of human reachable workspace may then be used to more accurately design human interface mechanisms which accomodate a wide variety of users. The results of our case study on the reachable workspace of the human finger wer used in the design of a fingertip haptic display. <p> Index terms: Anthropocentric mechanism design, ergonomics, stochasitic reachable workspace.
