Method for determining when a force sensor signal baseline in a force-based input device can be updated
Disclosed is a method for determining a force sensor signal baseline in a force-based input device. The method includes accepting a signal associated with touch activity and determining a signal range, wherein the signal range decays with time and is reset when the signal exceeds the current range....

| Zusammenfassung: | Disclosed is a method for determining a force sensor signal baseline in a force-based input device. The method includes accepting a signal associated with touch activity and determining a signal range, wherein the signal range decays with time and is reset when the signal exceeds the current range. A touch event is declared when the signal range exceeds a predetermined activity threshold. A previously determined baseline is held when a touch event is declared, and updated when a touch event is not declared. |
