メモ
- Up (Tip switch=0、In-range=1)とOut of Range (Tip switch=0、In-range=0)は別にレポートしなければいけない。
- Devices that do not support hovering do not need to include the In-range usage in their descriptor.
Windows 7/マルチタッチ
- If the device supports z-axis detection, it reports in-range when the transducer is within the region where digitizing is possible. If the device does not support z-axis detection, the driver should set in-range and tip switch when a finger comes in contact with the digitizer.
