ARKit can provide plausible pose even with fake isTracked. See how to avoid unsafe decisions and maintain stable gestures.
Direct answer
The visionOS 26 notes explain that a hand joint can receive a plausible transformation even when isTracked is false, for example in low light or temporary occlusion. For tasks that require precision, the application must check isTracked before trusting the pose. In custom gestures, however, stopping everything at the first loss can create instability; the design needs to combine confidence, time window, confirmation and safe fallback.
Estimated pose and tracked pose are distinct states
A continuous transformation can improve appearance, but should not be confused with reliable measurement.
Critical accuracy requires explicit gate
Dangerous selection, measurement or machine command must block when the required linkage is not tracked.
Gestures tolerate small gaps
Filters and short windows can preserve continuity as long as they do not invent intent or hide prolonged loss.
Environment is part of the product
Lighting, object occlusion and hand position must be included in the test script, not just in the documentation.
Nexus Reading
Model trust states and associate each action with the minimum level required. The interface should show when it is waiting for recapture.
FAQ
isTracked false means no transformation?
No. ARKit can return a plausible transformation anyway.
Can I use this pose for critical action?
Not without additional validation; Apple recommends checking isTracked when high accuracy is required.
Should I cancel every gesture at the first loss?
Not necessarily. Personalized gestures may need to continue through brief occlusions, with clear boundaries.
