http://teavuihuang.com/mocap
Mocap Phone is a mobile application that enables a suitable Accelerometer-equipped mobile phone to be a limited 2-axis / 3-axis motion capture device that records human / object movements for applications such as 3D animation, movies and games. The data is exported to the de facto Hollywood special effects mocap standard - Vicon C3D, as well as Autodesk FBX, Acclaim AMC & ASF and a direct Maya MEL format.
