The Future is Markerless 

At DARI, we wanted to take objective, whole-body biomechanical analysis out of the lab and into the real world. So, we developed a system that captures comprehensive biomechanics at the fidelity of marker-based systems, in a fraction of the time. 

The DARI Difference

Zero markers, zero setup time–the future is markerless 

Marker-based motion analysis requires up to 45 minutes of marker placement for every session. This makes it difficult for motion analysis to fit in the day-to-day work of wellness providers and trainers. DARI uses an eight-camera markerless motion capture system to acquire an accurate skeletal model instantly, so analysis begins the moment a subject steps into the capture space.

  • Easy collection. Precise data capture that fits your workflow.
  • Time efficient. Complete a full analysis in under five minutes.
  • Collect at population scale. Scan 50 to 100 people per-day, per-system, depending upon analysis type.
  • Real-time data collection. No cumbersome setup or post-processing is required.

Track Changes Over Time With Sub-millimeter Accuracy 

We engineered our markerless system to track at sub-millimeter accuracy between sessions. Our technology can reliably show changes to the movement system over time.

Most other markerless systems use a single consumer-grade depth camera originally developed for console gaming. These lack accuracy, capture a limited amount of the body, and can’t capture explosive, high-speed motions at their native 30 hz framerate. DARI uses eight high-speed cameras placed around the subject and a state-of-the-art computer-vision engine to collect whole-body data–including the fastest motions.

Traditional motion labs require manual application of reflective markers on the body, causing up to 20% marker-placement error between sessions. Marker-based systems can not accurately track biomechanical data over time.


Take A Biomechanics Lab With You–Anywhere 

DARI is completely portable using optional accessories, and works in almost any indoor environment. We track:

  • 21 bone segments, nine joints, with six-degrees of freedom
  • Kinematics and kinetics in all planes
  • Range of motion
  • Joint torques
  • Internal/external rotation at the hip
  • Shoulder ab-duction
  • Anterior/posterior coronal deviation
  • Neuromuscular engagement, center of mass sway in all planes
  • All joints in space

Capture Whole Body Kinematics And Kinetics–Without Force Plates 

Traditional motion labs use cumbersome floor-mounted pressure plates to measure the forces generated by the body. These require frequent calibration, and restrict the subject’s movement to a limited area. DARI’s patented, 3rd-party validated kinetic capture collects kinetics without force plates. That means DARI can measure joint torques, ground reaction forces, and other force measurements without restricting the subject’s natural movement.
