Seated subjects reached to and operated 12 toggle switch controls located 31, 41, and 51 inches above the floor and 0, 25, 50, and 75 degrees to the left of the mid-sagittal plane. The effects on reaction time, reach time, and total response time of three-variables--control location, visual fixationuncertainty, and anthropometric size of subjects--were investigated. Analyses of variance indicate that control location and visual fixationuncertainty affect reaction, reach, and total response time but body size does not. Derived scores were also analyzed to permit detailed examination of the perceptual-motor components of the response scores. The linear relationships between reach rate and reach distance observed in this study are compared with the curvilinear relationships reported in micromotion literature. To aid in evaluating control arrangements, response-time isograms are presented. Author
