mma766ofc加速度傳感器的手機

　　加速度計在手機市場上迅速擴散，使得智能創新能夠繼續幫助開發者區分產品和競爭對手。

　　根據iSuppli，加速度計，迅速滲透手機市場，而且似乎在不久的將來不會。正如他們預測的，大約2010的移動電話中有三分之一是MEMS加速度計。這一比例從2008的五上升到2009的11。加速度計允許用戶使用手指敲擊和三維運動來執行特定命令，通常取代了多擊鍵的需要。

　　例如，手機用戶要求復雜的用戶界面，允許快速、精確的通信，而不需要復雜的數據輸入。他們還希望這些功能在預算價格的手機以及高端機型。飛思卡爾MMA7660FC低g，三軸數字加速度計是該公司的第一個是專為移動電話和其他小的手持設備。低成本，低功耗智能感應在一個緊湊的包可以添加巨大的功能，以便攜式電池供電的設備，沒有空余的余地。

　　Essentially， MEMS combine silicon-based microelectronics with micromachining technology. A three-axis accelerometer can detect motion on three different planes， or axes. This allows developers to implement a single accelerometer to incorporate tap， shake， and orientation detection in a mobile device. For instance， a back-and-forth shake and an up-and-down shake can be used to execute two different commands. Although accelerometers can be used in a number of hand-held applications， mobile phones have dominated the market. Accelerometers not only enable developers to incorporate clever innovations that differentiate their products from the competition， but also to extend revenue opportunities to ISVs （independent software vendors）， interface providers， and wireless service carriers.

　　The MMA7660FC accelerometer can be employed to detect natural user interactions， including：

　　Orientation detection that goes beyond automatically adjusting to a portrait or landscape configuration

　　Single-tap detection， which can be configured at user-selectable thresholds and time duration on the X， Y， and Z-axes

　　Shake， which can be used to represent specific keystrokes or a series of keystrokes

　　Gesturing and gaming moves， such as three-dimensional tilt， turn， and twist

　　However， portable devices such as mobile phones demand more than improved functionality alone if they want to carve out a profitable piece of the market. The inherent limitations of size and battery life， among others， must also be addressed.
