Дата публикации: 03-05-2012.A touchscreen device is configured to display a number of user interface elements in accordance with a menu hierarchy. Upon receipt of a predetermined touchscreen gesture (e.g., the circular motion of a manipulator) the menu hierarchy is bypassed and the user is given immediate control over a selected function, for example, a tuning function such as audio volume, screen contrast, and the like. 1. A user interface method comprising:displaying, on a touchscreen display, a plurality of user interface elements;entering a first mode, the first mode including providing a signal responsive to touch events associated with the user interface elements;determining whether a touch event corresponds to a predetermined touchscreen gesture; andswitching from the first mode to a second mode when the touch event corresponds to the predetermined touchscreen gesture, the second mode including providing, for the duration of the touch event, a signal indicative of a value of a selected function that is not associated with the displayed plurality of user interface elements.2. The user interface method of claim 1 , wherein the selected function is a tuning function associated with a user's interaction with the touchscreen display.3. The method of claim 2 , wherein the tuning function is a volume level of an audio signal configured to be provided to the user.4. The method of claim 2 , wherein the tuning function is a visual characteristic of the touchscreen display.5. The method of claim 1 , wherein the predetermined touchscreen gesture includes a circular motion.6. The method of claim 5 , wherein the circular motion starts from an initial position on the touchscreen display that is not associated with the user interface elements claim 5 , and wherein the value of the tuning function is based on the arc subtended by the circular motion with respect to the initial position.7. The method of claim 1 , further including temporarily displaying a graphical depiction of the value of the tuning ...
