近年來智慧型手機愈來愈普及，不僅運算能力強，智慧型手機上也搭載了多樣化的感應器，讓使用者能得到更多環境中的資訊，其中，磁感應器已成為智慧型手機上的標準配備。 本論文藉由分析智慧型手機上磁感應器的角度資料，計算出手機轉動的角速度、角加速度，來達到類似陀螺儀感應器的功能；我們還利用磁感應器偵測到的角度變化，推算出手機沿著同一軸向上的移動位移；最後我們將手機轉動的角度、角速度與角加速等資訊結合拉邦動作分析理論，對使用者的動作進行判斷與分類，藉此了解使用者的動作特性。 In recent years, smart phones become increasingly popular. More than having strong computing ability, smart phones are equipped with a variety of sensors. Users can get even more information by the sensors. Among the sensors, magnetic sensor has become the standard equipment on smart phones. In this thesis, we analyze the rotational angle of magnetic sensor on smart phones and calculate the angular velocity and angular acceleration of the smart phones to achieve the capability which is similar to gyro sensor. The magnetic sensor is used to detect the change of the angle and to predict the displacement of the phones moving along the same axis. Finally, the rotational angle, the angular velocity, the angular acceleration of the smart phones and the LMA theory are integrated to determine and classify the users’ motion. Through this determination and classification, the characteristics of user’s motion can be found out.
