MOCHA: MObile phone based Context sHAring

It is a recent trend to integrate advanced sensors, such as accelerometer and digital compass, into smartphones. This makes the smartphone an ideal platform for activity recognition. We expect in the near future, social networking services will go from location sharing to activity sharing, with the rapid development of smartphones. We are working on building a context sharing platform using smartphones, including thinking robust context detection algorithms and designing HCI for context sharing.
