- For
- Judo learners practicing belt tying and basic grips
- Worth noticing
- The webcam drill scores visible hand, wrist, and elbow positions, but explicitly does not assess grip depth, pressure, or technique effectiveness.
Field notes
For belt practice, the page offers a seven-step demonstration and a camera guide that follows two differently colored markers taped to the belt ends. Grip missions compare visible hand, wrist, and elbow positions with a virtual partner, with a 1.2-second hold completing a task. The page distinguishes this pose check from assessing real grip depth or pressure, and says video is processed on the device.
