구문

‘선언
Public ReadOnly Property Confidence As RecognitionConfidence
‘사용 방법
Dim instance As Gesture
Dim value As RecognitionConfidence

속성 값

형식: Microsoft.Ink.RecognitionConfidence
인식기가 제스처 인식에 대해 갖는 신뢰 수준(높음, 중간 또는 낮음)입니다.

설명

참고

신뢰도 평가는 현재 버전의 Windows XP Tablet PC Edition에 제공되는 모든 제스처 인식기에서 수행할 수 있습니다.

반환될 수 있는 신뢰도 값 목록을 보려면 RecognitionConfidence 열거형 형식을 참조하십시오.

예제

이 예제에서는 응용 프로그램 제스처가 인식되면 이벤트 처리기가 실행됩니다. 응용 프로그램에서 SetGestureStatus 메서드를 호출하여 특별히 요청한 ApplicationGesture 형식에서만 이벤트가 발생합니다. 이벤트 처리기에 전달된 첫 번째 Gesture 개체를 조사하면서 Confidence 속성이 Check 제스처에 대한 높은 신뢰 수준으로 설정되어 있으면 HotPoint 속성이 나타내는 좌표 주위에 작은 원을 그립니다.
