About Vicon Capture.U

Working seamlessly with Vicon Blue Trident sensors, Vicon Capture.U is a visual application for collecting raw inertial and analytic data, which is not limited by laboratory settings. It offers real-time data overlaid on video, enabling you to analyze movement both on the field and in the lab.

With modes for collecting and analyzing raw data, Capture.U enables you to view graphical and statistics information in real time. You can also save video or export data as CSV, X1D or PDF files, for further analysis.

For a brief introduction to Capture.U, see the PDF Vicon Capture.U Quick Start Guide.

This guide provides information on using both the Capture.U app, for iOS devices; and Capture.U Desktop, for use on Windows PCs and Macs.

You can also watch Vicon Capture.U videos, covering all aspects of using Capture.U, on YouTube.
