鼠标控制显示增益的绩效研究

目的研究探讨了鼠标控制显示增益对指点操作绩效的影响。方法采用实验室方法,实验一对鼠标控制显示增益与操作绩效的关系进行研究。实验二在实验一结果的基础上改进了鼠标自适应控制显示技术,对固定、自适应和自定义三种鼠标控制显示增益类型进行了比较研究。共有42名被试参与实验。结果(1)不同的鼠标控制显示增益会对操作绩效产生不同的影响,鼠标控制显示增益大小与操作绩效有着倒"U型"关系。(2)任务难度对操作绩效有着明显的影响,低难度任务操作绩效明显好于高难度任务;不同难度条件下,鼠标控制显示增益与操作绩效还是保持倒"U型"关系,但是对于不同难度的任务,用户获得最优绩效的特定的鼠标控制显示增益水平不同。(3)在不同的确定鼠标控制显示增益的方式中,考虑任务难度因素的自适应增益方式的操作绩效明显高于自定义和固定增益方式。结论在指点任务中使用自适应控制显示增益鼠标可提高操作绩效。

The Research of Performance Effect of Control-Display Gain of Mouse

Objective This study examines the effect of control - display gain on mouse pointing performance. Methods First experiment examines the relation between CD gain and performance on mouse. Second experiment ex- amines the effect of different CD gain type on performance on mouse. In total, 42 subjects participated in the experi- ments. Results （ 1 ） CD gain has significant effect on performance. There is an invert U - shaped profile for perform- ance versus CD gain. （2）Task in different index of difficulty has significant effect on performance. The performance of low - difficulty task is significantly superior to high - difficulty. There is also an invert U - shaped profile for per- formance versus CD gain and a particular CD gain on mouse to make users achieve optimal performance for task in dif- ferent index of difficulty. （3） The performance of adaptive CD gain which consider task in different index of difficulty is superior to adaptable CD gain and constant CD gain. Conclusion Researchers suggest that using an adaptive control display gain mouse could improve performance in pointing task.
