Human Factors Criteria for the Design and Acquisition of Non-keyboard Interaction Devices: A Revision to Chapter 9 of the Human Factors Design Standard

This document summarizes the process followed by the research team in the development of an updated and revised set of non-keyboard interaction device design criteria. The research and revision process used for creating this set of design criteria is explained in this document, followed by an appendix containing the design criteria itself. The material in the appendix is intended to replace the current material on non-keyboard interaction devices in the Human Factors Design Standard (HFDS).
