A staged R&D program building an open, scalable wearable measurement pathway from Movesense acquisition through OpenSense interoperability and OpenCap comparison.
Development sequence
The project progresses from one sensor to two and then staged 3-, 5-, and 10-sensor configurations before OpenSense and OpenCap comparison.
Each stage separates technical development from evidence of validity or clinical utility. A working pipeline is a prototype to evaluate, not a clinical claim.
Non-human bench evidence before any governed human feasibility.
Non-human timing and integrity before simple human feasibility.
Each sensor count passes non-human and prior human stop/go criteria.
Human activity requires a documented institutional governance determination. Feasibility does not establish validity, reliability, clinical utility, or an operational service.
Verify one-sensor acquisition on the bench before considering a governed one-sensor human feasibility session.
Complete the hardware and firmware inventory, then capture the first non-human bench recording.
Measure timing and integrity with two sensors, then stage 3-, 5-, and 10-sensor loads non-human before corresponding human feasibility.
Begin with a two-sensor non-human shared event after single-sensor acquisition is stable.
Establish calibration, fusion, coordinate, drift, magnetic, and invalid-state limits across supported sensor counts.
Start with one-sensor non-human static poses and prescribed rotations after the timing envelope is known.
Build reproducible OpenSense input, calibration, and inverse-kinematics acceptance after orientation limits are explicit.
Round-trip synthetic trajectories, then complete a non-human two- or three-sensor acceptance run.
Compare synchronized wearable and video estimates without treating agreement as accuracy or OpenCap as ground truth.
Begin only after Project 004 makes timing, orientation, placement, coordinate, and export limits explicit.
