Method and apparatus pertaining to the interpretation of touch-based actions

摘要

A control circuit can be configured to, in a shared mode of operation, interpret a first touch-based action as a cursor-control instruction while also interpreting a second touch-based action as a multi-touch gesture. Such a device can supplement a native cursor-free user-interface approach with a cursor-based selection-and-movement capability that is also responsive to touch-based interactions. That first touch-based action can comprise simultaneously touching the touch-screen display with two fingers that are spaced only within a predetermined range of each other. In such a case a cursor can be displayed between those two fingers. The user can then move that cursor by moving at least one of those fingers. By another approach the device can effect a cursor-based selection action upon detecting a momentary touch on the touch-screen display.
