我们提出了一种动态 C-D 增益自适应的新颖方法，可以改善运动障碍用户的目标获取能力。我们的方法称为角度鼠标，根据移动过程中采样的角度偏差来调整鼠标 C-D 增益。当角度偏差较低时，增益保持较高。当角度偏差较高时，增益会下降，使目标在运动空间中变大。角度鼠标的一个关键特征是，与大多数指向促进技术不同，它与目标无关，不需要了解目标位置或尺寸。这意味着可以避免干扰目标的问题，因为适应完全基于用户的行为。在一项针对 16 人（其中 8 人有运动障碍）的研究中，我们发现角度鼠标将运动障碍的指向吞吐量比 Windows 默认鼠标提高了 10.3%，比粘性图标提高了 11.0%。对于身体健全的用户来说，三种技术之间没有显着差异，因为 Angle Mouse 吞吐量在默认值的 1.2% 以内。因此，Angle Mouse 提高了有运动障碍的用户的指向性能，同时对身体健全的用户来说保持不显眼。
We present a novel method of dynamic C-D gain adaptation that improves target acquisition for users with motor impairments. Our method, called the Angle Mouse, adjusts the mouse C-D gain based on the deviation of angles sampled during movement. When angular deviation is low, the gain is kept high. When angular deviation is high, the gain is dropped, making the target bigger in motor-space. A key feature of the Angle Mouse is that, unlike most pointing facilitation techniques, it is target-agnostic, requiring no knowledge of target locations or dimensions. This means that the problem of distractor targets is avoided because adaptation is based solely on the user's behavior. In a study of 16 people, 8 of which had motor impairments, we found that the Angle Mouse improved motor-impaired pointing throughput by 10.3% over the Windows default mouse and 11.0% over sticky icons. For able-bodied users, there was no significant difference among the three techniques, as Angle Mouse throughput was within 1.2% of the default. Thus, the Angle Mouse improved pointing performance for users with motor impairments while remaining unobtrusive for able-bodied users.
