Abstract
A method for human-machine interaction includes monitoring a movement of an object by a sensor that detects positions of the object over time, generating a time-dependent velocity of the object based on the movement of the object, detecting a tapping event of the object tapping on a surface by detecting a sudden change of the time-dependent velocity, and determining a position of the object at a time when the tapping event occurs as a tapping position of the object.
