Inertial measurement units (IMU) combine an accelerometer and a gyroscope in a compact 6-axis system. The integration of

multiple sensor outputs bring motion sensing systems to the level of accuracy required for the most demanding applications,

such as enhanced gesture recognition, gaming, augmented reality, indoor navigation, and localization-based services. In its

latest generation of IMUs particularly suited to mobile applications, ST is embedding machine learning cores (MLC) for context

awareness. This enables accurate low-power edge processing that, together with the finite state machine (FSM), allows the

precise analysis and reconstruction of user activities and gestures.
