在資訊突破性、更新速率與廣泛應用的時代，穿戴式裝置、智慧型手機、智慧型家電系統已漸漸成為未來趨勢，除此之外也漸漸創造起許多品牌，推翻舊有的傳統手機系統大廠Nokia，而Android系統的頂尖研發廠Samsung、HTC與iOS系統的領導廠Apple角逐勢力，未來幾年智慧型手機系統也會與家電、穿戴式裝置結合，程為未來產品主流與趨勢，手勢判別操作更有可能融入各穿戴式裝置中，所以本論文以常見的g-sensor為重點分析。

本論文使用friendlyARM的Tiny4412搭載Samsung Exynos4412四核心處理器來做為開發平台，使用Android版本為4.2.2(Jelly Bean)，核心版本為Linux-3.5.0。

本論文的目標是將三軸加速感應器mma7660fc驅動移植至Linux-3.5.0上並編寫及修改Sensor HAL架構，讓其實現加速感應器資料傳輸並在Android畫面顯示實現依照使用者操作模式做適當的螢幕翻轉。再者，本論文嘗試以App應用程式在使用者空間下可驗證加速度數值是否傳輸正確。本論文最後以撰寫小型App遊戲讓整體系統做實質體驗。Sensor Driver、IIC、Sensor HAL、Application做整個架構分析修改及實現。

Breakthrough in the information update rate and age of widespread application of wearable devices , smart phones , smart appliances system has gradually become the future trend , in addition to gradually create from many brands , to overthrow the old large traditional phone system factory Nokia, and Apple competing forces leading factory Android system 's top research and development plant in Samsung, HTC and iOS system , the next few years will be the smart phone system appliances, wearable device combination products for the future mainstream processes and trends , gesture discrimination operations are more likely to integrate various wearable devices, so common in this thesis focus on g-sensor analysis .

In this paper, the use of Tiny4412 friendlyARM equipped Samsung Exynos4412 quad-core processor to do as a development platform , using Android version 4.2.2 (Jelly Bean), core version of Linux-3.5.0.

The objective of this paper is to triaxial accelerometer mma7660fc driver ported to Linux-3.5.0 and write and modify Sensor HAL architecture , allowed to achieve data transfer acceleration sensor and the screen display Android achieved in accordance with the user to make the appropriate operating mode flip the screen . Furthermore , this paper attempts to App in user space application to verify whether the correct transmission of acceleration values . Finally, this paper to write a small App game allows the overall system to make substantive experience. Sensor Driver, IIC, Sensor HAL, Application made to modify the whole structure analysis and implementation .
