MEMSIC announces a wearable connected watch development kit for context awareness, health and fitness, sports, motion and orientation detection
 
MEMSIC, Inc.(www.memsic.com), a leading MEMS solutions provider, announced here at CES 2014 the first of its kind connected watch SDK (MMW-SDK) with an integrated e-Compass.

Its availability facilitates the rapid development of a wide range of wearable consumer electronic applications with connectivity to Apple and Android platforms. Contact watchsdk@memsic.com to schedule a meeting at CES.

The MMW-SDK takes advantage of the ultra low power and small size of the recently introduced MEMSIC MMC3416xPJ magnetometer, allowing developers to create innovative, always-on, wearable applications that enhance the user experience and utility of mobile handsets and tablets. While using less than 50uA of current, the MMC3416xPJ can provide fast, highly accurate heading, rotation and attitude information which, combined with MEMSIC's sensor fusion software, will enable applications to understand the context of the user, such as whether the user is standing, sitting, lying, walking or running, and can also assist in indoor navigation applications. The SDK also provides a wireless connection to another mobile device, further simplifying the development and integration process.

The MEMSIC electronic compass software provides a highly accurate fully tilt compensated electronic compass with calibration that supports MEMSIC's recently introduced MMC3416xPJ ultra low noise, low power magnetometer in a 1.6 x 1.6 x 0.6 package. High heading accuracy of the compass is enabled by the high performance and low noise of the MMC3416PJ.

Integrating sensors can be complex and time consuming. A thorough understanding of the theory of magnetics, sensor behavior, calibration and tilt compensation is required before the design can start, and the digital outputs of counts per gauss need to be filtered, translated and correlated into a tilt compensated heading.

MEMSIC simplifies this integration by providing the necessary calibration libraries and sensor fusion software as part of the MMW-SDK. This SDK leverages MEMSIC's many years of experience as an IMU developer to provide the basic sensor framework on top of which the developer can build context awareness, motion and fitness applications.
