Conclusion

Advances in MEMS technology have significantly improved the size, cost, and power consumption of inertial sensors, enabling the handset market to create motion-aware applications. With the combination of the gyroscope, accelerometer, and compass, a highly accurate, robust, and latency-free motion processing solution can be established to revolutionize the way people use mobile phones.

A gesture recognition-based user interface will enable users to access their phones in a very easy and intuitive way most of the time with only a single hand. The inclusion of gyroscopes has raised the accuracy of motion capture to the degree that air signature authentication is possible. It also has brought the user experience of motion-based mobile gaming to a whole new level.

Further, motion processing will play an important role in the booming mobile commerce and LBS service application market. Higher-precision position estimation can be achieved, and better augmented reality experiences will be provided.
