1. A computer implemented method of responding to touch based user input, comprising:

  • determining position coordinates of a touch input region upon a user touching the touch input region;

    receiving an audio signal from a microphone upon the user touching the touch input region;

    determining an impact strength of the user'"'"'s touch based on the audio signal; and

    generating a first command that is associated with the determined impact strength if the determined impact strength exceeds a first threshold, and generating a second command, different than the first command, that is associated with the determined impact strength if the determined impact strength exceeds a second threshold, wherein a host computing device performs a first action based on the generated first command and performs a second action based on the generated second command.
