The use of a joy-stick in making settings on a simulated scope face

Abstract

To determine the significance of certain variables in the use of a joy-stick to make settings in two dimensions on a simulated scope face to a relatively coarse tolerance, 20 Ss each operated a joy-stick apparatus to bring a cursor in line with a marker on a disk face. When S thought they lined up, he pressed a switch. Time and errors were recorded. The most significant factor was the ratio of joy-stick-tip movement to cursor movement: the lowest optional ratio was two-and-a-half. Variations in joy-stick length or starting position, reversed operation, or location of S's switch were relatively unimportant. (PsycInfo Database Record (c) 2025 APA, all rights reserved)
