PointerPointProperties.TouchConfidence Property
Gets a value that indicates whether the pointer device rejected the touch contact.
Syntax
public:
property bool TouchConfidence {
bool get ();
}
Property value
Type: bool
True if the touch contact was accepted; otherwise false.
Remarks
A device rejects accidental touches and reports this information through the Human Interface Device (HID) confidence usage (see note below). TouchConfidence is set through the value of this usage.
The confidence usage helps improve the accuracy and reliability of accidental touch rejection. (In addition to confidence, additional heuristics are applied to the touch input stream to improve the accuracy of accidental touch rejection.)
Touch input is most often rejected due to palm detection or through input arbitration (such as when pen/stylus proximity overrides touch input).
Note
The core of the Microsoft interactive input device architecture is based on the Universal Serial Bus (USB) standard Device Class Definition for Human Interface Devices (HIDs), which is defined by the Universal Serial Bus (USB) Implementers Forum, Inc.
The Universal Serial Bus (USB) Human Interface Device (HID) standard defines the configuration and communication protocols for Human Interface Devices (HIDs), such as keyboards, mouse devices, joysticks, and virtual reality devices, that humans use to enter data directly into a computer. (For detailed information about the USB HID standard, see the USB Implementers Forum website.)
Although the core of the Windows input architecture is based on the Universal Serial Bus (USB) Human Interface Device (HID) standard, the architecture is not limited to Universal Serial Bus (USB) devices. The input architecture also supports serial port devices, i8042 port devices, and proprietary input devices.
