Wearable devices such as Google Glass, Fitbit, and iWatch are becoming more and more popular. These devices are equipped with sensors to measure movement and the world around us, with communications tools that put us in touch with work, home, family, friends, service providers and strangers. Such device is poised to teach itself how to work better, based upon how you use it, which applications you run, and how you use it to communicate with others. In this project, we will investigate machine learning methods and potential application on wearable devices.
