# isTracked

A Boolean value that indicates whether ARKit tracks a hand joint.

## Declaration

```swift
var isTracked: Bool { get }
```

## Discussion

Discussion When the environment provides insufficient lighting, or if an object occludes the hand joint, isTracked may return false. Even under these circumstances, ARKit returns a plausible transform for the joint. Check for isTracked when you require high accuracy for the joint transform. Don’t check for this property in situations where you expect to occlude hand joints, such as in a custom gesture implementation.
