PDF-(BOOK)-The Ergonomics of Computer Pointing Devices (Applied Computing)

We first began looking at pointing devices and human performance in 1990 when the senior author Sarah Douglas was asked to evaluate the human performance ofa rather novel device a fingercontrolled isometric joystick placed under a key on the keyboard Since 1990 we have been involved in the development and evaluation ofother isometric joysticks a footcontrolled mouse a trackball and a wearable computer with head173 mounted display We unabashedly believe that design and evaluation of pointing devices should evolve from a broad spectrum of values which place the human being at the center These values include performance iss173 ues such as pointingtime and errors physical issues such as comfort and health and contextual issues such as task usabilityand user acceptance This book chronicles this sixyear history of our relationship as teacher Douglas and student Mithal as we moved from more traditional evalu173 ation using Fitts law as the paradigm to understanding the basic research literature on psychomotor behavior During that process we became pro173 foundly aware that many designers of pointing devices fail to understand the constraints of human performance and often do not even consider experimental evaluation critical to usability decisions before marketing a device We also became aware ofthe fact that contraryto popularbeliefin the humancomputer interaction community the problem of predicting pointing device performance has not been solved by Fitts law Similarly our expectations were biased by the cognitive revolution of the past 15 years with the beliefpointing device research was lowlevel and uninter173 esting.
