Ergonomic Design of a Computer Mouse for Clients With Wrist Splints

Abstract

Both dorsal wrist splints and rear-hump mice are recommended. Length of index finger positively correlated with task performance.

An artificial immune algorithm for ergonomic product classification using anthropometric measurements

“…When hand tools are bigger or smaller than the hand size, long-term use can cause wrist pain. Liu and Fan (2014) considered four anthropometric measurements of the hand (width and length, palm, and index) in their study to examine the effects of cutaneous feedback and hump position on effective use of the computer mouse with a splint. Furthermore, Kwon et al (2009) selected three pivotal hand dimensions (length, circumferences, and breadth) to design gloves for candidates.…”

“…It is reported that mouse users adopt working postures of wrist extension, pronation, and ulnar deviation (Karlqvist et al, 1994;Fernström and Ericson, 1997;Cook and Kothiyal, 1998;Burgess-Limerick et al, 1999). Liu and Fan (2014) carried out a computer task by thirty participants utilizing two forms of computer mouses (front hump and rear hump) and two types of wrist splints (dorsal and volar) and measured the movement times and satisfaction scores.…”

“…Hsiao et al (2015) proposed an improved sizing scheme for fire-fighting gloves that appropriately fits the US firemen population. In another study, Liu and Fan (2014) considered four anthropometric measurements of the hand (width and length of hand, palm, and index) in their study to design an ergonomic computer mouse for clients with wrist splints.…”
