Performance of Rolling Ball and Isometric Joystick on a 2-D Target Alignment Task

Abstract

A Rolling Ball and a Rate Controlled Isometric Joystick were employed in a target alignment task with dimensions comparable with those of many ATC tasks. In addition to amplitude and target width, variables included three levels of control-display relationship (gain), and direction of movement. The two devices were compared on a number of dimensions including overall performance time, the rate of incorrect responses, adherence to Fitts' Law and directional biases. This last factor proved significant only in the case of the joystick. The study concluded that; a) the rolling ball was still the preferred device for the ATC environment and should be retained; b) control-display relationship had no effect on the performance measures employed. Keywords include: Rolling Balls, Isometric Joysticks, Input devices, Fitts' Law, and Gain
