dc.description.abstract | 本論文提出了一個以三軸加速度計來取代普遍用於商業滑鼠裝置的光學感測器的新型慣性滑鼠裝置。本 論文所使用的慣性感測器為加速度計,其具有減少能量耗損、縮減整體產品大小以及減低整體產品成本的優點,另外因為此種新型的 慣性滑鼠裝置可以隔空使用,所以也增加了其可使用的範圍。 本論文以光學感應器及三軸加速度計來實現所提出的 慣性滑鼠裝置,因此能在相同環境及條件下比較兩種不同感應器﹝光學感應器及慣性感應器 ﹞的效果。本論文以不同的數學方法以及從加速度計所得到的訊號來估測滑鼠裝置的位移量。 在最初時,這些實現的演算法皆以個人電腦為核心並搭配慣性滑鼠裝置來做測試,最後最適合的演算法則以微控制器來實現,整個 裝置成為一個獨立的新型慣性滑鼠裝置。 實 驗結果顯示出,本論文所提出的以加速度計為基礎的最佳估測技術可 以做為新型的慣性滑鼠裝置,且應用在一般的電腦上可以順利完成大多數的工作。 | zh_TW |
dc.description.abstract | This work proposes and evaluates an inertial mouse device based on three-axis accelerometer to be a substitute of the optical sensor, which is commonly used in the majority of commercial mouse devices. The use of inertial sensors, such as accelerometers, will allow reducing power consumption, physical dimensions and final product cost, moreover will increase easy-of-use, since this kind of mouse could be also used in free space. For this purpose, a prototype containing an optical sensor and 3-axis accelerometer is built. In this way, it is possible to compare the two sensors under the same environment and conditions. In a first moment, different mathematical approaches are tested to estimate the displacement based on the acceleration signal. Those approaches are processed under a computer application connected to the prototype. By the end, the most suitable algorithms are ported to the microcontroller embedded in the prototype. The result of the experiments show that the best estimator techniques based on the accelerometers can be used as a mouse device to perform the majority of the tasks when interacting with a computer. | en_US |
