2/8 In this paper, we give ideas for how pose estimation algorithms should change to best serve movement science -- by quantifying different variables, better ground truth, tracking in time, and more...

4/8 Exciting progress in pose estimation in-the-wild promises to take movement science outside the lab: study real-world non-contrived movements, increase number of subjects, realize low-cost science and medicine & do science on existing videos i.e. not run experiments ourselves.

5/8 But, existing algorithms don’t serve the needs of movement science yet. Main reason for this is: they largely ignore underlying dynamics and treat each video frame as independent from its neighbors. In reality, each frame imposes a strong prior for poses in nearby frames.

6/8 Secondly, because they ignore the physical range of motion constraints imposed by our body. These oversights (among others) result is weird errors when tracking videos of interest to movement science:pic.twitter.com/2B5HGJzcM5
