ProMove-mini represents a new class of highly-scalable, ultra-synchronized wireless networked inertial and orientation sensors. Using the latest MEMS sensor technology available, ProMove-mini is specifically designed for fine-grained, high-throughput motion capture.
ProMove-mini features a complete set of 3-D digital sensors, offering 10 DOF sensor data: acceleration, turn rate (gyroscope), magnetic field intensity (compass), high-g acceleration and barometric pressure. Full 3-D orientation information, expressed as quaternions, is also made available to the user.
A network comprises tens of devices that sample and transmit motion and orientation information at high data rates in a fully synchronized manner. The synchronization accuracy is less than 100 ns. The number of nodes in the network scales with the sampling rates, e.g. a network can have 39 nodes that sample at 200 Hz, or 19 nodes that sample at 500 Hz, or 9 nodes that sample at 1 kHz.
The sensor data is transmitted using the low-power 2.4 GHz wireless radio to a central node, Inertia Gateway, which connects to the computer through USB. Alternatively, ProMove-mini can be equipped with a Dual-Mode Bluetooth module for direct communication to PCs, smartphones and tablets. The sensor data can be stored on the on-board microSD card and retrieved later over USB or wirelessly.
ProMove-mini is carefully designed for good ergonomics. The curved design makes mounting and wearing on body parts comfortable, without affecting stability in case of surface mounting.
The Inertia Studio software enables real-time visualization of sensor data, as well as over-the-air reconfiguration of the sensors and wireless parameters. All data retrieved by the Inertia Studio software is logged for post-analysis.
For integrating the motion capture data coming from ProMove-mini with custom software, C++ and Java SDK packages are available on our download page.
