Some idea for a use case for this patent are:
- writing pad or keyboard
- secondary touch display or full size iPad connection
- smarter magnetic recognition
Also, hidden within the patent language is a magnetic ring that can control an iPad's Hall Effect sensor. On current Apple iPad, the Hall Effect sensor is used to determine the existence of the SmartCover. This is used to determine sleep/wake controls within the power state of the tablet. With this newly uncovered feature enabled, a user wearing a magnetic ring ould "swipe" across the sensor to activate certain functions.
This all seems pretty cool..
