Movement wearables / fictional development range
Start with how
it is worn.
Watch, ring or clip: define the wearing task, then agree the sample, firmware and app boundaries. Movement concepts without medical claims.

One movement brief. Three wearing forms.
The form factor changes the fit review, charging approach and data responsibility.
Wear → Review → Revise
A sample plan before a performance promise.
Choose the form
Wrist, finger or clip changes the sample-size set, attachment and charging approach.
Review the wearing task
Use a buyer-managed fit protocol. Review edges, adjustment and material documentation on physical samples.
Name the data owners
Device firmware, application and movement interpretation need distinct responsibility boundaries.
Application boundary
Movement concepts. Clear responsibilities.
Agree the sample form, firmware owner and synthetic output review. There is no health dashboard, personal telemetry or clinical claim hidden behind the render.
