有运动障碍的计算机用户在使用传统鼠标指向时面临着重大挑战。这些挑战主要是由于目标获取最后阶段的精细指向校正造成的。为了减少校正相位指向的需要并减轻小目标尺寸对捕获难度的影响，我们引入了四个增强型区域光标，其中两个依赖于放大倍数，其中两个使用目标交叉。在一项针对运动障碍和健全用户的研究中，我们将新设计与点光标和气泡光标进行了比较，后者尚未针对运动障碍用户进行评估。视觉电机放大镜和点击十字这两种增强型区域光标是针对运动障碍用户最成功的新设计，与点光标相比，小目标的选择时间减少了 19%，校正子移动减少了 45%，错误率减少了高达 82%。尽管气泡光标也提高了性能，但有运动障碍的参与者一致更喜欢增强的区域光标。
Computer users with motor impairments face major challenges with conventional mouse pointing. These challenges are mostly due to fine pointing corrections at the final stages of target acquisition. To reduce the need for correction-phase pointing and to lessen the effects of small target size on acquisition difficulty, we introduce four enhanced area cursors, two of which rely on magnification and two of which use goal crossing. In a study with motor-impaired and able-bodied users, we compared the new designs to the point and Bubble cursors, the latter of which had not been evaluated for users with motor impairments. Two enhanced area cursors, the Visual-Motor-Magnifier and Click-and-Cross, were the most successful new designs for users with motor impairments, reducing selection time for small targets by 19%, corrective submovements by 45%, and error rate by up to 82% compared to the point cursor. Although the Bubble cursor also improved performance, participants with motor impairments unanimously preferred the enhanced area cursors.
