A touch-sensitive display surface having touch-capacitive and vibration sensors. This surface allows the user to rest their fingers on the keys of an onscreen keyboard and type as they would on a regular keyboard. As the user places their fingers on the touch screen, the system relocates the onscreen keyboard to the location where the fingers are resting. The touch sensors report the signal strength level of each key touched to a processor, but no keystroke is issued by the processor until a corresponding tap (i.e., 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. The size, position, and orientation of the onscreen keyboard keys are dynamically set as determined by the user initiating a home-row definition event by resting their fingers momentarily on a virtual home-row. |
