DeviceMotion transforms an iPhone into a Bluetooth motion tracking sensor. By leveraging the devices inbuilt inertial sensors, the app generates and transmits motion data comprising orientation (expressed as a quaternion) and acceleration, using a specified Bluetooth protocol.
The application also includes a data logging feature, enabling users to record, store, and share inertial data in a structured log file via the standard iOS sharing features.
DeviceMotions codebase are readily available on GitHub (https://github.com/Proavatar/BleMotionTracker.git). The documentation is available at https://www.proavatar.io/devicemotion and details its design, functionality, and the necessary Bluetooth protocols.
DeviceMotion is a practical tool for developers interested in Bluetooth and motion tracking applications, providing an accessible and efficient method of generating, recording, and transmitting inertial data.
