The Best among Six Strategies for Selecting a Minute Target and the Determination of the Minute Maximum Size of the Targets on a Pen-Based Computer
Xiangshi Ren, Shinji Moriya · 1997
This study concentrates on finding the relationship between target-pointing strategies and target sizes. Concretely, an evaluation experiment was performed in which the experimental system used five kinds of targets (1, 3, 5, 7 and 9 dot diameter circles in respectively, 0.36 mm per dot), eight pen-movement-directions and six strategies of systematic election on a pen-based computer. The results showed that the “Land-on2” strategy was the best strategy for selecting a minute target, in terms of error rates, selection time and subjective preferences. “The minute maximum size” of 5 dots was also determined to be the largest size among the targets which had a significant main effect on the six strategies in terms of error rates.
