Arikex Puts Motion Capture in an iPhone
Arikex presents a markerless motion-capture system that uses one to four iPhones to produce a metric 3D skeleton from high-speed video.
Field notes
Arikex describes a capture pipeline that begins with high-speed iPhone video and a 1.2-second LiDAR pre-roll, then estimates bone lengths, stature, scale, and the floor before solving a 26-keypoint body model. The page distinguishes live preview at 60 fps from recording at up to 240 fps and says one to four phones can be used, with two-phone triangulation available. It also describes a wrist remote and a handheld camera-tracking mode for later stabilization.
