Abstract
The influence of various parameters on the design of selection strategies was investigated. Our question is, do changes in the size, distance or direction to a target affect the differences in performance between selection strategies? We performed an experiment on a pen-based system to evaluate the effect of size, distance and direction on six strategies for selecting a target. Three target sizes, three pen-movement-distances, and eight pen-movementdirections were applied to all six strategies. The results show that the differences between selection strategies are affected by target size (when target size decreases below a certain size, differences between selection strategies appear; conversely, differences between selection strategies disappear when target sizes are increased beyond a certain size). The results also show that the differences between selection strategies are not affected by pen-movement-distance and pen-movement-direction. Issues relating to the merits of individual strategies will be the focus of planned future investigations.
