| 20090073128 | CLEANABLE TOUCH AND TAP-SENSITIVE KEYBOARD - 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. | 03-19-2009 |
