Design exercise: Pose & Motion Tracking
Landmarks, skeletons, optical flow, temporal smoothing, identity tracking, calibration, occlusion, and latency. Implement designOutline() returning non-empty values for: landmarks, temporalTracking, occlusionHandling. Each value must name a concrete mechanism or decision.
The mechanism
Pose tracking is temporal estimation under ambiguity. Combine per-frame evidence with identity, motion priors, smoothing, and explicit confidence through occlusion.
Expected evidence
A design outline with landmarks, temporalTracking, occlusionHandling plus an explicit failure mode or trade-off.

Hints when you need them
- Name the failure mode before selecting the mechanism.
