VZDaq™ V1.0 provides several functions that allow the user to synchronize 3rd party analog signals with real-time VZSoft™ motion capture data via a wide range of National Instruments A/D cards.
The VZDaq™ toolbox can handle up to 80 analog channels simultaneously and provide real-time graphs for each analog source during capture. Multiple VZDaq™ stations can be networked together to provide more than 80 analog channels of synchronized data. In combination with a host of VZSoft™ automation controls, the toolbox can be set up to automatically record and synchronize external analog channels for later integration with the motion capture data file. The newly combined file can be examined in VZAnalyzer™ or be ported to LabView, MatLab, etc. In addition, VZAnalyzer™ always facilitates direct real-time analysis of all analog signals during the capture process for biofeedback and various industrial applications. The user has full control over the sampling ratio of analog to motion capture frames - i.e., if 1000 analog samples correspond to 100 motion capture samples the user can set a 10/1 ratio for proper alignment.
VZDaq™ can be operated on the same PC as VZSoft™ but also collect data on a remote monitoring station -in synchronicity- and then send its information via TCP/IP to the motion capture workstation. This can reduce the analysis workload on the main computer and gives the option of maintaining previously dedicated monitoring stations for force plates, EMGs, robotic interfaces, etc., without having to heavily modify them for the motion capture process.
All features are designed to minimize the user's set-up time for 3rd party hardware integration and to provide an intuitive data synchronization interface.
