Touch interface having microphone to determine touch impact strength

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 command that is associated with the determined impact strength, wherein a host computing device performs an action based on the command.

An electronic apparatus, comprising:

• a position identifier to identify position coordinates corresponding to a location of a touch input region touched by a user;
• an audio analyzer to receive an audio signal generated by an audio sensor when the touch input region is touched by the user and to determine an impact strength of the user's touch based on the audio signal;
• and
• a controller to receive the position coordinates from the position identifier and the impact strength from the audio analyzer, and to generate a command that is associated with the determined impact strength, wherein a host computing device to perform an action based on the command.
