摘要： Improved means and methods to sense rotation using magnetic field sensors, inductance sensing and capacitive sensing employ a user interface comprising a knob and an integrated circuit containing a magnetic field sensor and inductance measuring circuitry. A permanent magnet and a metal member are attached to the knob, allowing detection of rotation of the knob and when the knob is depressed. A first press is interpreted as an activation command, a subsequent rotation is detected, indicated and stored, a second press is interpreted as a deactivation command and a third press is interpreted as a command to reactivate and automatically select a specific rotational position.

摘要： A method for a smart phone app is provided wherein entry to a secure data storage area is facilitated on a file or object level, and not on an app level, wherein the secure data storage area is hidden from the normal application display or view. To obtain an interface which allows entry into the secure data storage area, a user may perform one or other input action, gesture or other step, wherein these are linked with a specific file or object.
