Multipurpose programmable adjustable keyboard (MPAK)

A mobile device comprising:

• a configurable input surface comprising:
• an IM comprising a first and second side, said first side for displaying a plurality of input indicia displayed on a first side;
• a MMS comprising first and second electrode sheets, said first electrode sheet coupled to said second side of said generally planar IM;
• and
• a piezo sheet interposed between said first and second electrode sheets;
• a memory in which is stored configuration data for said IM, said MMS, and said piezo sheet;
• and
• a processor coupled to said memory, said IM, said MMS, and said piezo sheet.

A method comprising:

• providing an IM on which is displayed a plurality of input indicia;
• detecting a force applied to said IM and a position at which said force is applied;
• determining at least one of said plurality of input indicia corresponding to said position at which said force is applied;
• and
• providing tactile feedback in response to said determination of said application of force.

A device comprising:

• means for displaying a plurality of input indicia;
• means for detecting a force applied to said means for displaying and a position at which said force is applied;
• means for determining at least one of said input indicia corresponding to said position at which said force is applied;
• and
• means for providing a tactile feedback in response to said detection of said applied force.

A program of machine-readable instructions, tangibly embodied on an information bearing medium and executable by a digital data processor, to perform actions directed toward interacting with a display, the actions comprising:

• dynamically configuring a display comprising a plurality of input indicia;
• detecting a force applied to said display and a position at which said force is applied;
• and
• providing tactile feedback in response to said determination of said application of force.
