SelectPressedValue ranges from 0.0 to 1.0, with 0.0 representing no Select press and 1.0 representing a full Select press. IsPressed will only return true once the SelectPressedValue reaches 1.0. If a given source can only detect an on/off state for Select presses, the value will always be 0.0 or 1.0.

Select represents the primary press for a spatial interaction source:

  • For hands, a Select press represents the user's index finger in the down position.
  • For motion controllers, a Select press represents the controller's index-finger trigger (or primary face button, if no trigger) being fully pressed.
  • For voice, a Select press represents the user saying the system keyword "Select".

Note that a voice "Select" causes an instant press and release, and so you cannot poll for a voice press using IsPressed, IsSelectPressed or SelectPressedValue. Instead, use a SpatialGestureRecognizer and handle the Tapped event, or handle the SourcePressed event.
