Vicon Reveals Comprehensive Inertial Tracking System to Advance Training and Research in Sports and Academia
High-G Sensor Designed for Use With Three Separate software platforms for Multiple Applications; Blue Trident, Mobile App and IMU Step to debut at NATA, Available for purchase late August 2019
OXFORD, UK – June 24, 2019 – Today, Vicon announces Blue Trident, a lightweight wearable sensor capable of capturing the highest g data possible, and the focal point of a new inertial ecosystem to drive the future of sports, biomechanics and research. Using the new sensor, anyone from athletes in the field to researchers in the lab can record performance data and process it through one of three software platforms: Vicon Capture.U, the free iOS mobile app to deliver real-time data review and analysis, overlaid on video; IMU Step, the lower limb load monitoring tool to aid return-to-running and reduce reinjury risk; and Vicon’s Nexus 2.10 software, to integrate inertial data into optical mocap.
“June 27 is the two year anniversary of the acquisition of IMeasureU, and Blue Trident — together with Capture.U, Nexus 2.10 and IMU Step — is the outcome of that collaboration, combining everything we’ve learnt through our research and listening to our customers,” said Imogen Moorhouse, Vicon CEO. “Through our shared experience we are in a unique position to offer the best possible ecosystem to track, analyse and optimise human movement for athletes and teams — from grassroots to elite — and the sports scientists, practitioners, clinicians and biomechanists that support them.”
Fusing Vicon’s 35 years of industry-leading motion capture R&D with IMeasureU’s expertise in inertial tracking, Blue Trident excels when it comes to the data it records with the dual-g IMU, capable of capturing up to 200g, easily handling even the highest peaks of elite athlete movement. The low g sensor tracks lower intensity movements at 16g and both sensors measure movement simultaneously, ensuring high-fidelity data capture while eliminating sensor saturation. Blue Trident contains a gyroscope to record angular velocity and a magnetometer to determine direction as well.
Blue Trident is also IP68 rated, for use in water, adverse weather or underwater treadmills. As a user walks, runs, jumps or swims, the sensor records the impact of each movement, storing that data in the sensor’s 1GB of onboard memory, or streamed via Bluetooth 5 to a mobile device for review and analysis. The information can help assess an athlete’s performance in order to increase output or chart recovery, making it ideal for use with running-based sports, including basketball, rugby and football, along with cricket, swimming and more.
“Motion capture is fast becoming an essential tool not only for biomechanics research but for sports injury rehabilitation and training at all levels,” said Dr Kim Duffy, Vicon life sciences product manager. “Blue Trident builds on the success of its predecessor. Data download speed is five times faster, it’s 25% smaller and lighter, and battery life is extended to up to 12 hours.”
As part of the Blue Trident ecosystem, Vicon is releasing Capture.U, a free mobile app compatible with iOS 10x and up. Users can connect multiple sensors to provide real-time overlay of data on video, or use one of the built-in “capture modes” to provide precise human movement insights faster in the field. Data can be recorded in free capture mode with personalized benchmarks set by the user. Specialized activity widgets to monitor jumping, sprinting, counter rotation, swimming and a power meter will be released in the near future. The capture can be reviewed in the app, and the video saved and exported with the data overlay or in PDF and CSV format through multiple means, including Apple AirDrop. Using the Capture.U Desktop companion app, data can also be exported via CSV for further analysis.
For athletes and trainers looking to optimize their training regimens or rehabilitate from injuries in running-based sports, Blue Trident will work with IMeasureU’s updated IMU Step software. IMU Step measures the musculoskeletal impact of each limb through every step taken and calculates cumulative bone loading and stride symmetry. Using these metrics — and the faster workflow in the updated software — athletes and trainers can better monitor and manage lower limb load in the field, reduce return-to-running risk, increase athlete availability and ultimately improve performance.
“Most wearable tracking technology is designed to address general use cases and is typically a single unit worn on the centre of mass or wrist,” said Matt Clarke, director of business development, IMeasureU. “Our approach with IMU Step is precise and specific. Subjects wear a high-fidelity, synchronized sensor on each ankle, the source of the running load, to accurately quantify the intensity of every step they take, on both limbs – whether they’re a professional player in rehab from an injury or a school track team looking to improve their times.”
For biomechanists and researchers looking to expand their work within a lab setting, Blue Trident is the only motion capture ecosystem with hard synchronization. Vicon IMUs are natively integrated, enabling plug-and-play use of the sensors in Vicon Nexus, the world’s most clinically-validated life sciences mocap software. With hard sync, Nexus 2.10 accesses the full sensor capability for highly accurate synchronization of inertial data with the precise tracking data from Vicon’s optical cameras. Within Nexus 2.10, Blue Trident will offer quaternions: global angles that calculate orientation and rotation of a joint in three dimensions, allowing biomechanics researchers to add inertial data on joint impacts and limb movement, to further develop the scope of their research.
“What we have seen so far with Vicon’s new technology is very exciting, especially the integration of video with the live IMU data feed,” said Jacqueline Alderson, assistant professor, University of Western Australia. This is a game changer for those working with athletes in the field. [As researchers] We want the numbers but for the athlete and coach the vision is everything.”
Availability/Compatibility
The Blue Trident sensor will make its official debut on June 24 at the National Athletic Trainers Association’s 70th Annual Clinical Symposia & AT Expo in Las Vegas, Nevada. Blue Trident will then be available late August directly from Vicon and through distributors around the world. The Capture.U app will be released at the same time through the Apple App Store at no cost, and is compatible with devices running iOS 10x and up, equipped with Bluetooth 4.2 or better.
Nexus 2.10 will be available free of charge to all current Nexus 2 license holders this autumn. The IMU Step update is available now at no cost to active license holders.
