Xsens MTw Awinda with NexGen HM-Analyzer-X

NexGen Ergonomics is a Xsens system integrator and can provide a total solution with our HM-Analyzer software.

HM-Analyzer-X Software

Our HM-Analyzer maps from one to 15 inertial sensors to various segments of the body (such as trunk, pelvis, arms, etc.) in order to obtain joint angles according to ISB - International Society of Biomechanics (ISB angles are also anatomical angles) or according to AAOS. The software and system are totally scalable allowing you to use any number of sensors as required. The skeleton which is used for visualization can be adjusted according to the subject's anthropometry.

The software takes care of joint definitions and conversions. The user simply needs to identify the segment that is mapped to the specified sensor.

The application synchronizes the data automatically. The user can then perform various analyses within HM-Analyzer or export data.

The calibration procedure consists of the user selecting either the T-pose or I-pose (posture) and clicking "Calibrate" or using the auto-calibration option.

Animation allows you to replay a recording or an offline imported file. You can zoom in and out on the graphs using the mouse wheel.

Recording duration time can be set manually or automatically by specifying the start and end recording time.

DATS (Data Analysis Tool Set) Module

The DATS (Data Analysis Tool Set) module is included and performs a variety of joint angle analysis, filtering and data export. The DATS module provides a graphical user interface (GUI) to perform data analysis. The analysis can be done with streaming (real-time) data or with data that was previously recorded.

The interface uses a graph layout to create various analyses. Tools are available to easily connect the graphical blocks. Data processing block layouts can be saved for reuse.

The DATS module includes various filtering options, biomechanical tools to calculate joint angles (according to the ISB or AAOS) as well as various signal processing tools.

DATS also includes a variety of data filtering options that can be applied which include Butterworth, Chebyshev (1 & 2) and Bessel.

Saved analysis can be saved for reuse or future modifications.
