1. A method of discerning user input on a solid planar touch-sensitive surface, the method comprising:
- at a processor,recording two or more concurrent user touches of the solid planar touch-sensitive surface based on two or more signals generated by a plurality of touch sensors included in the touch-sensitive surface;
receiving vibration signals from one or more vibration sensors coupled to the touch-sensitive surface; and
determining whether the vibration signals constitute a user tap event, based on pre-defined criteria; and
correlating the two or more concurrent user touches with the determined user tap event to disambiguate between the user resting on the touch surface and asserting a selection on the touch surface, thereby outputting an action associated with the asserted selection,wherein the touch sensors are physically and operationally different than the vibration sensors.

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 system comprising:
-
a means for recording two or more concurrent user touches of the solid planar touch-sensitive surface based on two or more signals generated by a plurality of touch sensors included in the touch-sensitive surface; a means for receiving vibration signals from one or more vibration sensors coupled to the touch-sensitive surface; and a means for determining whether the vibration signals constitute a user tap event, based on pre-defined criteria; and a means for correlating the two or more concurrent user touches with the determined user tap event to disambiguate between the user resting on the touch surface and asserting a selection on the touch surface, thereby outputting an action associated with the asserted selection, wherein the touch sensors are physically and operationally different than the vibration sensors.
