[143] Citation: 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.
Index terms: Anthropocentric mechanism design, ergonomics, stochasitic
reachable workspace.
