光标控制设备和目标方向对指点绩效的影响

Impact of Cursor Control Devices and Target Orientation on Pointing Performance

【目的】探究不同光标控制设备和目标方向对指点绩效的影响,旨在提高人机交互效率。【方法】基于ISO 9241-9国际标准设计多目标方向指点任务,邀请30名被试参与实验,获取被试使用普通鼠标、拇指式轨迹球、嵌入式滚球鼠标的反应时、正确率和主观评分。【结果】使用三种光标控制设备的正确率无显著差异,反应时存在显著差异;目标方向对正确率无显著影响,对嵌入式滚球鼠标反应时有显著影响。【结论】①在进行交互界面图标位置设计时,使用拇指式轨迹球交互优先考虑水平向左方向(180°);使用嵌入式滚球鼠标时,优先考虑垂直向下方向(270°)。②在用户疲劳度方面,拇指式轨迹球的使用最为轻松。③在进行简单人机交互任务时,使用普通鼠标优于拇指式轨迹球和嵌入式滚球鼠标。

[Purposes]This paper investigates the effects of different cursor control devices and target direc⁃tions on pointing performance,aiming to improve the efficiency of human-computer interaction.[Methods]Based on ISO 9241-9,we invited 30 subjects to participate in the experiment,and obtained the reaction time,correctness rate,and subjective scores of the subjects using a normal mouse,a thumb trackball,and an embedded rolling ball mouse.[Findings]There was no significant difference in the correct rate of pointing when using the three cursor control devices,and there was a significant difference in reaction time.The target direction had no significant effect on the correct rate but a significant effect on the re⁃sponse time of the embedded ball mouse.[Conclusions]①When designing the icon position of the interac⁃tion interface,the horizontal leftward direction(180°)is prioritized when using the thumb trackball interac⁃tion;the vertical downward direction(270°)is prioritized when using the embedded rollerball mouse.②In terms of user fatigue,the thumb-based trackball is the easiest to use.③When performing simple human computer interaction tasks,the use of an ordinary mouse is superior to the thumb trackball and the em⁃bedded ball mouse.
