论文摘要
我们提出了一种新的鼠标光标，旨在促进外周视力丧失的人使用小鼠。指针由覆盖整个屏幕并遵循鼠标光标的位置的收敛直线的集合组成。我们在一组参与者中测量了其积极的效果，这些参与者具有不同种类的外围视力丧失，我们发现它可以减少使用鼠标完成目标任务所需的时间7倍。使用眼睛跟踪，我们表明该系统可以使朝目标运动启动，而无需精确找到鼠标指针。使用FITTS定律，我们将这些性能与完整视野用户的性能进行比较，以了解估计的鼠标光标位置的准确性与使用我们的工具获得的性能索引之间的关系。
We present 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 with a group of participants with peripheral vision loss of different kinds and we found that it can reduce by a factor of 7 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 towards 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.
