眼动交互中对象排列方式对作业绩效的影响(英文)

Task Efficiency of Different Arrangements of Objects in an Eye-movement Based User Interface

由于人眼注视的方位能够表达用户的兴趣中心等信息,使得基于眼动的用户界面备受关注,同时眼动也成为攫取当前认知加工过程的一个窗口。本研究采用2排列方式×6目标项位置的被试内设计,主要考察了眼动人机界面中交互对象的不同空间排列方式及目标项位置对选择工效的影响,以期为设计和优化基于视线追踪的人机交互界面的布局提供心理学依据。所获得的主要结论如下:(1)在基于视线追踪的人机交互中,对象水平排列方式优于垂直排列方式;(2)不同对象排列方式影响目标项位置对作业时间的效应模式,对象水平排列时,作业时间随着目标位置右移而线性递增;垂直排列时,作业时间随目标位置下移以非线性方式递增;(3)目标项位置仅影响目标定位时间,目标激活时间不受对象空间排列方式和目标项位置的影响;(4)基于视线追踪的人机交互系统其对象排列方式以水平方式为宜。

The main reason that eye-movement based user interfaces are attractive is that the gaze direction of eyes can express the interests of the user - it is a potential window of cognitive processes and communication through the gaze direction of the eyes is faster than any other modes of human communication. In this study, a 2arrangement×6tasget position within subject factorial design was used to compare different arrangements of interactive objects for an eye-movement based interface suitable for the general GUI environments such as Microsoft Windows. We found that ： （ 1 ） In eye-movement based human computer interaction, the selective efficiency was higher for horizontal arrangements than for vertical arrangements. （2） The arrangement of objects affected the effect of target position on task time. When the objects were arranged horizontally, with the target moving right, task time increased linearly, but when the objects were arranged vertically, with the target moving down, task time increased nonlinearly. （3） Target position only affected the time of target localization in both arrangements. In addition, the time of target activation was not affected by the arrangement of objects and the target location. Therefore, objects should be arranged horizontally in interactive systems based on eye tracking technology.
