Abstract
A user input system comprising a vibration motor, a sensor and a processor in communication with the sensor. The vibration motor is in contact with a surface and generates vibrations in the surface. The vibrations can be altered by a user touching the surface to create altered vibrations. The sensor is in contact with the surface and detects the altered vibrations. The processor receives and analyzes data corresponding to the altered vibrations. The processor determines, based on the analyzed data, whether a user's touch on the surface matches a stored vibration profile of the user.
