We introduce here a new mouse cursor designed to facilitate the use of the mouse by people with peripheral vision loss. The pointer consists of a collection of converging straight lines covering the whole screen and following the position of the mouse cursor. We measured its positive effects in a group of participants with peripheral vision loss of different kinds and found that it can reduce by a factor of seven the time required to complete a targeting task using the mouse. Using eye tracking, we show that this system makes it possible to initiate the movement toward the target without having to precisely locate the mouse pointer. Using Fitts' Law, we compare these performances with those of full visual field users in order to understand the relation between the accuracy of the estimated mouse cursor position and the index of performance obtained with our tool.
我们在这里介绍一种新的鼠标光标，旨在方便周边视觉丧失的人使用鼠标。该指针由一组汇聚的直线组成，覆盖整个屏幕并跟随鼠标光标位置。我们在一组具有不同类型周边视觉丧失的参与者中测量了它的积极效果，发现它可以将使用鼠标完成目标定位任务所需的时间缩短到原来的七分之一。通过眼动追踪，我们表明，该系统使得可以在不必精确定位鼠标指针的情况下就开始向目标移动。使用 Fitts 定律，我们将这些性能与具有完整视野的用户进行比较，以了解估计的鼠标光标位置的准确性与我们工具的性能指标之间的关系。
