iSen is a 3D inertial motion capture system developed by STT which analyzes the movement of the human body. It is very advantageous in certain cases: for example, when portability is strictly required, high-end inertial sensors like STT-IWS may well suit the needs of those who need a quick analysis on a specific joint or even on the entire body, but do not wish to be bound to a certain location.
An iSen system is prepared to work with various sensor configurations, from a simple, 1-sensor configuration to a 16-sensors, full-body configuration; all of them working at a sampling rate of 25 to 400Hz.
Database with management of captures by subject, ability to export and import captures (the basic 3GC file format, in which recordings are stored, is proprietary and is a container for all data sources and biomechanics.
Ready-to-use analysis protocols In iSen, each analysis protocol is made up of 5 components that help conduct the analysis very efficiently. These components are: the predefined sensor placement, a 3D scene definition with visual elements, a dashboard with real-time calculations, a graphs module and an automated report generator with templates.
3D visualization of the movement in real time, including perspective views and predefined orthogonal views: left / right side, top, front, rear.
Automatic report generation including analysis results. The templates for these reports are customizable by the user. They can include raw data, tables and / or graphs, fixed texts, information from the database, etc.
Design of new protocols. The possibility of developing new protocols on demand is offered.
Representation of biomechanical parameters through temporal graphs. These graphs are updated in real time, that is, during recording.
Assignment of temporary events or automatic detection, depending on the analysis model. Example: in gait analysis, automatic detection of initial contact and take off.
Biofeedback: Possibility of defining rules to check certain conditions in real time. The system informs the user when these conditions are met during recording. Example: Angle> certain value.
Integration and synchronization with external measurement devices. High-speed video cameras (60FPS, 100FPS, 120FPS, etc.), measurement of the electrical activity of muscles (EMG) or the reaction force of the ground using force platforms.
Export of capture data for import into other applications (for example Matlab), and biomechanical curves in CSV format for import into other applications (for example MS Excel).
Video synchronization for reference from low cost webcams to high performance cameras such as those mentioned in the previous point.
