SELF-ADAPTIVE DISPLAY ASPECT RATIO ADJUSTER AND GESTURE ON ROLLING DEVICES

摘要

A device and method for intuitively optimizing the size of a displayed visual content (9) on a rollable display device (1), wherein either the visual content (9) is optimally scaled to current dimensions of a front screen (5), or a touch-sensitive display (4) is rolled to a required extent that optimally displays a best possible aspect ratio for the visual content (9) after obtaining a permission using an input gesture (10), such as a multi-touch "spread" or "pinch" gesture. The touch- sensitive display (4) can further be rolled manually between a rolled-in (18) and rolled-out (19) state using "shake-to-roll" movement gestures.
