PerceptionTimestamp PerceptionTimestamp PerceptionTimestamp PerceptionTimestamp Class

Definition

Represents a particular prediction of the future, or a snapshot of the past.

Passing one PerceptionTimestamp instance to multiple API calls ensures that they all return results based on the same set of predicted data, even if Windows has improved predictions available. This ensures that you can correctly correlate the data you get back from these APIs.

Value
TimeSpan TimeSpan TimeSpan TimeSpan

The prediction duration.

Remarks

When you get an improved prediction (for example, from a newer HolographicFramePrediction, TargetTime will stay the same and PredictionAmount will decrease.

For timestamps about the past, PredictionAmount is always 0, even if the data associated with this timestamp was interpolated between two readings.

TargetTime TargetTime TargetTime TargetTime

Gets the specific time that is the subject of this timestamp.
