Operating method for computing devices

摘要

A method for the easy input and operation of computing devices and electronic devices with limited space for input components. The method allows for a plurality of input functions using only two buttons in a method of contextual navigation. The two buttons provide numerous input functions which are continually graphically displayed such that the user can always discern the action which will occur when one or both buttons are depressed. Different functions occur with the pressing of each one of the buttons yielding two functions whereas pressing both buttons for a short period yields a third function. Additional utility is provided through the use of voice commands which may be associated data upon voice communication. A third button facilitates the entering and retrieval of voice data. Text may be entered using the method and is enhanced by prediction of input characters from a grid of characters selectable using the buttons.
