An Ergonomic Computer Keyboard for Conventional,Straight Keyboard Users: Ergonomic Research in Generative Product Design

Abstract

Straight, conventional keyboards are still the most popular design among those shipped with new personal computer sales and standalone keyboard retail sales. Many keyboard users are reluctant to switch to a more ergonomic keyboard – designs that reduce awkward wrist postures. Ergonomic research led to a design of a new keyboard providing more ergonomic benefit to the masses of conventional, straight keyboard users while being equally or even more preferred. The result was a keyboard: Microsoft Comfort Curve ® Keyboard, designed with a subtle split angle of 12° (instead of 24° of traditional ergonomic keyboards), extending the keys' sizes within this split. The design goals were to reduce ulnar deviation and to maintain approachability and typing performance.
