眼动控制的交互式地图设计

An Interactive Map Based on Gaze Control

  • 摘要: 传统的地图交互方式主要包括鼠标键盘控制和触摸设备控制,对根据人类视觉通道、利用眼动控制进行地图交互的研究还很少。眼动数据可以透露出人的心理状态和兴趣,因此将其作为地图交互的输入信息可以增加应用的可靠性和便利性。首先利用Tobii EyeX眼动仪获取眼动数据,将该数据作为地图交互的输入信息,提出了注视点过滤算法和注视多边形定位算法;然后设计了眼控控件及其交互响应方式,解决了地图眼控交互中存在的注视点冗余、交互反馈延迟问题,并开发了一套眼动控制的交互式地图原型系统;最后通过比较用户分别使用眼动控制和鼠标控制完成相同地图浏览任务的耗时及表现,对地图眼控交互算法和原型系统进行了评价。

     

    Abstract: Common interactive maps are usually controlled by mouse, keyboard and touch, but there are few studies which directly use eye gaze to control map interaction. Since gaze implies humans' psychological state and area of interest, its application, as the input of map interaction, is not only helpful to the disabled but may make interactive maps easier to use.We employ TobiiEyeX eye tracker as the input device. Firstly, for fixation point redundancy and feedback delay in the gaze-controlled interactive map, we introduce the method of acquiring gaze data, fixation point filtering algorithm and gazed polygon localization algorithm. Furthermore, we design controls controlled by gaze and develop a prototype system of the gaze-controlled interactive map. Finally, we design an experiment to evaluate the algorithms and the prototype system. In the experiment, we compare the time taken by users to complete the same map-browsing task with gaze control and mouse control. The result shows that the proposed methods are effective and the prototype system can be used well.
