| 摘要 |
A pen-shaped mouse device or a finger mouse device, an acceleration correction method and a position computation method are disclosed. The mouse device includes an image sensor (1), an acceleration sensor (2) and a micro-control and information transmission unit (4), wherein the micro-control and information transmission unit (4) is used for receiving optical displacement information and acceleration information. The method includes: when the positioning by the image sensor (1) is good, the computed acceleration according to the displacement information detected by the image sensor (1) and the acceleration detected by the acceleration sensor (2) are compared to obtain a correction value of the acceleration; when the positioning by the image sensor (1) is poor, the displacement is computed according to the original effective displacement information optically detected and the corrected acceleration displacement information.
