TOUCHPREDICTIONPARAMETERS structure (winuser.h)

Contains hardware input details that can be used to predict touch targets and help compensate for hardware latency when processing touch and gesture input that contains distance and velocity data.

Syntax

typedef struct tagTouchPredictionParameters {
  UINT cbSize;
  UINT dwLatency;
  UINT dwSampleTime;
  UINT bUseHWTimeStamp;
} TOUCHPREDICTIONPARAMETERS, *PTOUCHPREDICTIONPARAMETERS;

Members

cbSize

The size of this structure, in bytes.

dwLatency

Latency in milliseconds.

dwSampleTime

Sample time in milliseconds (used to calculate velocity).

bUseHWTimeStamp

Use timestamps provided by the hardware.

Remarks

By default, touch prediction is activated. For information on getting pointer data without deactivating touch prediction, see GetUnpredictedMessagePos.
