CLEANABLE TOUCH AND TAP-SENSITIVE KEYBOARD
First Claim
1. A method of detecting user input on a solid planar touch-sensitive surface to determine the location of a user'"'"'s input, the method comprising:
- recording user touches of the touch-sensitive surface based on a plurality of touch sensors included in the touch-sensitive surface;
receiving a tap event signal from one or more vibration sensors coupled to the touch-sensitive surface based on a tap event sensed by the one or more vibration sensors; and
asserting a selection after the tap event signal is received based on the recorded user touches.

Abstract
A touch sensitive surface having touch-capacitive and vibration sensors. This surface allows the user to rest their fingers on the keys and type as they would on a regular keyboard. As the user places their fingers on the keys, the touch capacitive sensors (one per key) report the signal strength level of each key touched to a processor, but no keystroke is issued by the processor until a corresponding “tap” (ie. vibration) is detected. When a tap is detected, the processor references the status of the touch capacitance sensors before, during, and/or immediately after the moment in time the tap occurred.

37. A method of detecting user input on a solid planar touch-sensitive surface wherein touch sensors only are included to determine the location of the users input, the method comprising:
-
recording user touches of the touch-sensitive surface based on a plurality of touch sensors included in the touch-sensitive surface; determining if a recorded user touch changes according to a predefined change threshold; and asserting a selection if user touches are determined to change according to the predefined change threshold.
