Does Jump Strength Predict Kick Speed? The Support-Leg Secret in Soccer2026年7月8日
Does single-leg jump strength predict soccer kick speed? In 6 amateur players, the dominant leg kicked harder (99 vs 85 km/h) — but the real surprise was that a stronger non-dominant support leg went with a faster dominant-leg kick.
How Accurate Is ARKit for Motion Capture? I Measured It Across 10 Exercises2026年7月8日
Apple’s ARKit turns an iPhone into a markerless 3D motion tracker — but how accurate is it? I tested it across 10 exercises with 11 participants. Single joints at peak flexion were within ~3°, but errors near full extension and the floor reached up to 63°.
5 Apps That Put Motion Capture in Your Pocket — Do They Work?2026年7月8日
Can a smartphone app really measure how you move? Five motion-capture apps — ViMAS, KinesioCapture, Coach’s Eye, LGait, and SmartGait — have been validated against VICON and 3D systems. Here’s the accuracy each study actually found, app by app.
Can Your Phone Fix Your Form? 3D Motion Capture with ARKit2026年7月8日
Can your phone measure how you move accurately enough to fix your form? Here’s why Apple’s ARKit — 3D motion capture from ordinary 2D video, auto-calibrated and real-time — is a promising answer, and how it compares with VICON, 2D video, and Kinect.
3D Markerless Motion Capture: Which Setup? 3 Approaches Compared2026年7月6日
Three ways to capture 3D movement without markers — single-camera AI depth, a depth sensor, or multiple cameras. Here’s how they compare on accuracy, cost, and setup, and how to choose.
Which Pose-Estimation Model Is Most Accurate? 6 Models vs the Gold Standard (VICON)2026年7月5日
We benchmarked pose estimation accuracy across six models — MediaPipe, MeTRAbs, YOLO and MoveNet — against the VICON gold standard. Two clear tiers emerged; here’s which to use, and when.
