计算机鼠标的位移传感器位于不同的位置(中间、前面和后面)。然而，关于传感器位置的影响或利用传感器位置的工程方法的研究还很少。本文首先讨论了传感器位置影响鼠标移动的机理，并报告了一个传感器位置系统变化的指向任务的研究结果。将传感器放置在中心是最好的折中方案:前后的改进在11-14%的范围内，20-23%的路径偏差范围内。然而，用户的个人最佳状态各不相同。在此基础上，提出了一种可变传感器定位的小鼠模型，并证明了两个静态光学传感器可以实现高精度的定位。描述了一种虚拟传感器模型，该模型允许传感器在软件端重新定位。与默认的中心位置相比，个别特定的校准应该会使吞吐量增加4%。

原文题目：Optimal Sensor Position for a Computer Mouse

原文：Computer mice have their displacement sensors in various locations (center, front, and rear). However, there has been little research into the effects of sensor position or on engi- neering approaches to exploit it. This paper first discusses the mechanisms via which sensor position affects mouse move- ment and reports the results from a study of a pointing task in which the sensor position was systematically varied. Placing the sensor in the center turned out to be the best compromise: improvements over front and rear were in the 11–14% range for throughput and 20–23% for path deviation. However, users varied in their personal optima. Accordingly, variable-sensor- position mice are then presented, with a demonstration that high accuracy can be achieved with two static optical sensors. A virtual sensor model is described that allows software-side repositioning of the sensor. Individual-specific calibration should yield an added 4% improvement in throughput over the default center position.
