Abstract
The Keybowl keyboard is the first known keyboard alternative to totally eliminate finger movement and drastically reduce wrist motion. With the significant reduction of finger and wrist motion comes concern over where the repetitive forces are being transferred. In typing with the Keybowl, biomechanical requirements are somewhat different than those in using a QWERTY keyboard. One way to help determine how well typists perform biomechanically is through keystroke error analysis. Typing performances were therefore analyzed via keystroke errors to determine if Keybowl “key” activation was different from QWERTY key activation. An error analysis for each character, hand, and gender was performed. This analysis has built a foundation for comparing two very different types of upper extremity motions and how they might affect a proficient QWERTY typist's performance in typing with the Keybowl.
