Effects of Optimizing the Scan-Path on Scanning Keyboards with QWERTY-Layout for English Text

Stud Health Technol Inform. 2017;242:930-938.

Abstract

Scanning keyboards can be essential tools for individuals with reduced motor function. However, most research addresses layout optimization. Learning new layouts is time-consuming. This study explores the familiar QWERTY layout with alternative scanning paths intended for English text. The results show that carefully designed scan-paths can help QWERTY nearly match optimized layouts in performance.

Keywords: Scanning input; assistive technologies; motor dysfunction and impairment; text entry.
