計算機鼠標的位移傳感器位於不同的位置(中間、前面和後面)。然而，關於傳感器位置的影響或利用傳感器位置的工程方法的研究還很少。本文首先討論了傳感器位置影響鼠標移動的機理，並報告了一個傳感器位置系統變化的指向任務的研究結果。將傳感器放置在中心是最好的折中方案:前後的改進在11-14%的範圍內，20-23%的路徑偏差範圍內。然而，用戶的個人最佳狀態各不相同。在此基礎上，提出了一種可變傳感器定位的小鼠模型，並證明了兩個靜態光學傳感器可以實現高精度的定位。描述了一種虛擬傳感器模型，該模型允許傳感器在軟件端重新定位。與默認的中心位置相比，個別特定的校準應該會使吞吐量增加4%。

原文題目：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.
