Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0031] Because the button layout of the software interface with buttons is not regular, therefore, in this embodiment, for each software interface, a button scrolling order array corresponding to the interface is introduced, and the elements of the button scrolling order array store According to the index of the button, when the scroll wheel is scrolled, the interface focus switches among the buttons in the button scrolling order array in sequence.

[0032] In order to realize above inventive conception, with reference to figure 1 , is the appearance diagram of the device of the present invention...

Abstract

The invention provides an idler wheel operating device and an operating method thereof. The idler wheel operating method comprises the following steps: an input signal is received; an identifier of a button that is focused in a present interface is obtained; whether the signal is a rolling operation signal is determined; if the signal is not the rolling operation signal, the function of the focused button is executed; if the signal is the rolling operation signal, an array of rolling order information of buttons in the present interface is obtained; an index identifier of the focused button in the array of rolling order information is obtained; the index number is moved forward or backward according to the rolling direction, and a corresponding button at the position after the index movement is obtained; the obtained new button is focused. The idler wheel operating device realizes the operating of complex interfaces of application software with buttons by the idler wheel, and has simple operation and convenient use.

Description

technical field [0001] The invention belongs to the technical field of navigation, in particular to a scroll wheel operating device and method. Background technique [0002] At present, the global positioning system (Global Positioning System, GPS) for vehicles is one of the important application directions of GPS navigation. The GPS antenna of the car GPS navigation system receives the data information transmitted by at least 3 of the 24 GPS satellites around the earth, combined with the electronic map stored in the car navigation terminal, the position coordinates determined by the GPS satellite signal and this match to determine the exact position of the navigation object in the electronic map. [0003] In the existing GPS navigation system, when the user uses the non-touch mode to operate the interface, he generally uses the six keys of the up key, the down key, the left key, the right key, the confirm key, and the cancel key to input commands, that is, The arrow keys ...
