2. Screen Coverage Input requirements apply equally to all areas, including edges and corners. Input requirements apply equally to all areas, including edges and corners.

3. HID (Human Interface Device) Class Multi-touch digitizers must appear to the OS as HID designers, and not as a mouse or other proprietary device. Multi-touch digitizers must appear to the OS as HID designers, and not as a mouse or other proprietary device.

4. Battery Operation For battery operated devices, the requirements must be met whether the device is running on AC or battery power. For battery operated devices, the requirements must be met whether the device is running on AC or battery power.

5. Sampling rate At least 50hz per finger At least 50hz per finger –USB supports up to 133hz

6. Resolution At least 100ppi and at least display resolution At least 100ppi and at least display resolution

7. Jitter For all finger, if a contact is stationary, the reported position data must not change. For all finger, if a contact is stationary, the reported position data must not change.

8. Contact Accuracy Tracing a line, circle, or other pattern should produce data that is within 0.5mm of the expected data pattern Tracing a line, circle, or other pattern should produce data that is within 0.5mm of the expected data pattern And without interruption to the pattern And without interruption to the pattern –Incorrect up/down data destroys integrity of linear movements.

9. Contact Offset The physical contact with the device and the position which the device reports must be with 2mm of each other for all fingers. The physical contact with the device and the position which the device reports must be with 2mm of each other for all fingers. –Reduce offset is crucial to accuracy Applies whether each contact is stationary or in motion, and when multiple fingers make contact simultaneously or separately Applies whether each contact is stationary or in motion, and when multiple fingers make contact simultaneously or separately

10. Ghost Points No data must be reported for locations where contact is not made. No data must be reported for locations where contact is not made.

11. Beyond Windows 7 Logo Contact width / height Contact width / height Pressure Pressure Valid touch confidence (and do it fast) Valid touch confidence (and do it fast) –OS won ’ t do palm rejection otherwise Double-tappings Double-tappings –Many users life the fingers only a small distance off the screen to double-tap

12. Beyond Windows 7 Logo Performance Performance –Device side gesture detection strongly discouraged –Palm rejection should be especially fast Set the `touch valid` sooner rather than later Set the `touch valid` sooner rather than later Pen use on touch screen Pen use on touch screen Input should not be triggered by dust or small insects Input should not be triggered by dust or small insects
