Utilization of a force sensor to signal intent to undock a device

A tablet computer system comprising:

• a dock;
• a tablet computer which can be removably docked from the dock, the tablet computer comprising an electronic display;
• one or more force sensors formed on the dock and/or the tablet computer for detection of a force or pressure distribution associated with docking and/or undocking of the tablet computer from the dock;
• and
• one or more processors configured to:
• determine a change from a first position of the tablet computer by detecting a change in the force or pressure distribution with the one or more force sensors;
• and
• determine a second position of the tablet computer based at least in part on the change.

A method of tracking docking and undocking of a tablet computer from a dock, the method comprising:

• determining a force or pressure distribution from one or more force sensors interfaced, directly or indirectly, with the tablet computer;
• determining a change from an initial position of the tablet computer by detecting a change in the force or pressure distribution detected by the one or more force sensors;
• and
• based on the determination of the change, releasing the tablet computer from the dock by modifying a state of electropermanent magnets located on the dock.
