Usage ID Usage Name Usage Types 説明 51 Contact identifier DV The ID of the current contact. 0E Configuration CA The Collection Application for the top-level collection that houses the configuration feature report. 52 Device mode DV A read/write value feature to get and set the current input configuration of a device. 23 Device settings CL The logical collection that contains the device configuration usages (Device identifier and Device mode). 53 Device Identifier SV/DV This is a static value (SV) when it is part of a digitizer or mouse top-level collection. 54 Contact count DV The usage that is specifically for devices that report all current contact information by using the parallel or hybrid mode 55 Contact count maximum DV A read-only feature for getting the total number of contacts that a multitouch device supports.
Reporting Modes
- Windows supports three ways of reporting multitouch data to the system:
- Serial mode: Each packet contains a single contact update.
- Parallel mode: Each packet is “wide” enough to support reporting the maximum number of contacts that the device can detect.
- Hybrid mode: Each packet contains a fixed number of contacts (less than the total number that the device can detect), and multiple packets are sent to convey all the contact data.
