　　毫無疑問，下一代智能手機的設(shè)計者將在他們的材料清單中添加陀螺儀，以增強游戲功能和室內(nèi)基于位置的服務(wù)。

　　一些供應(yīng)商，如半導(dǎo)體，是使它更容易為設(shè)計者利用模數(shù)轉(zhuǎn)換器通道在加速度計陀螺儀和其他容易同伴芯片集成。

　　但是，最有可能的是，我們將開始看到，除了多軸陀螺儀，更多的多傳感器包結(jié)合加速度計和陀螺儀。

　　驅(qū)動這些多傳感器設(shè)備的需求，特別是對移動電話和游戲平臺的需求，將是簡化設(shè)計和簡化供應(yīng)鏈的需要。雖然許多數(shù)字羅盤已經(jīng)納入GPS手機的加速度計，陀螺儀（又名常規(guī)速率或偏航傳感器）和加速度計剛剛開始集成在同一模塊中。

　　Like any other integrated device， an important step in their widespread adoption will be competitive pricing compared to discrete solutions.

　　While the key motivations for high integration are saving space and simplifying the design work for signal processing， integration also has to be cheaper than discrete solutions， said Jérémie Bouchaud， director and principal analyst MEMS， iSuppli Corporation.

　　According to Bouchaud， multisensor packages cost about 10 to 15 percent less than the costs of individual sensors.

　　The compass for a GPS phone always needs an accelerometer for calibration， which is why it makes sense to integrate it in the same package， said Bouchaud. The same thing will happen with gyroscopes， particularly for cell phone and gaming applications， he said.
