摘要
本研究探讨GUI环境中目标的方向、大小和距离对鼠标指点定位和拖动操作的影响。实验结果表明 ,鼠标指点定位和拖动操作的MT随着目标距离的增加而增加 ,随着目标的增大而减小 ,但下降率呈递减趋势。对于指点定位任务 ,目标方向对鼠标操作的MT有影响 ,而对于拖动操作任务 ,这一影响不明显。总体上 ,以上 3个因素交互地影响鼠标操作的MT。根据本实验数据 ,我们为上述两种常规鼠标操作任务建立了 8个方向的费茨模型。这些结果有助于GUI的工效学设计。
The study examined the effect of the target direction,size and distance on the mouse operation of pointing and dragging in a GUI environment.The result of the experiment showed that the Movement Time(MT)of the pointing and dragging was decreased as the result of increased distance between targets,and decreased size of the target.Target direction seemed to have significant influence on the MT of the pointing.The interaction effect of the target direction,size and distance was also found on the MT of mouse operation.Base on our experiment data,a Fitts' mode for mouse pointing and dragging in eight directions was developed.The implication of the result to the ergonomic design of GUI was also discussed.
