Abstract:
The embodiments herein provide a passive keyboard system that allows a user to enter a text into a mobile device by tapping the passive keyboard surface. The system comprises a passive keyboard, a microphone array, and a processor. The microphone array detects the audio levels of keystrokes created by the user while tapping the passive keyboard surface and sends the detected audio levels to the processor. The processor maps the detected audio levels to a standard keyboard audio typing pattern to determine the keys pressed by the user. The processor generates key-events corresponding to the keys pressed and sends the key-events to an operating system of the mobile device. The OS forwards the key-events to an internal keyboard system which displays text on the mobile screen.

Claim (Index 7):
A computer implemented method comprising instructions stored on a non-transitory computer readable storage medium and run on a computing device provided with a hardware processor and memory for detecting the keystrokes in a passive keyboard using the audio levels of the keystrokes, the method comprising the steps of:\n entering a text in a mobile device by tapping on a passive keyboard surface which is provided external to the mobile device; detecting the audio levels of the keystrokes created by the user while tapping on the surface of the passive keyboard using an array of microphones; receiving the detected audio levels of the keystrokes from the array of microphones and mapping the received audio levels of the keystroke to the standard keyboard audio typing patterns for determining the keys being pressed by the user using a processor; and generating the key-events corresponding to the keys being pressed and sending the key-events to an Operating System (OS) of the mobile device.
