System Integration
Integration with the MTw is very straightforward with the Xsens MT Software Suite. The MT Software Suite is an easy-to-use API which can be interfaced with via a COM, C and C++ interface with support for Windows and Linux. The components of the MT Software Suite are:
| Xsens Device API | Easy to use Xsens Device API to communicate with the MTw Awinda interfaces for common programming languages. |
| Example code | Example code To make starting with the MTw even easier, example code is provided for various platforms, amongst others Matlab and Linux. |
| MT Manager | An intuitive GUI for Windows, including configuration and recording tools, graphs and a wireless configuration setup to help understand the Xsens Awinda System. |
| Magnetic Field Mapper | Magnetic Field Mapper An algorithm and tool to calibrate the MTw for hard and soft iron effects. The calibration can be done during normal operation; there are no restrictions on the trajectories or rotations. |
| Documentation | Documentation Full (HTML)-documentation on the MTw, API, SDK and application notes. |
| Synchronization | Tried and tested synchronization of data acquisition systems with Xsens: Synchronization with EMG Systems
Synchronization with Optical Systems
Synchronization with Pressure Mats
Synchronization with EEG systems
