Motor and perceptual optimization of user interfaces

点击翻译按钮获取中文摘要

A program of research is proposed that will focus on "motor and perceptual optimization of user interfaces". User interfaces are broadly interpreted as any computing device used by humans, for example, conventional desktop or tabletop systems, notebook or laptop systems, tablet systems, mobile devices, or PDAs, The motor and perceptual aspects of the research pertain to the human output (motor) and input (perceptual) channels that are engaged as humans interact with computing technology. Optimization is a reference to the use of empirical research methods to test alternative interfaces. Design options are tested and compared in user studies, with better performing options advancing for further optimizing and testing, and poorer performing options discarded.
