Abstract: An electronic device and an operation method of parameter selection are provided. According to the method, a first parameter adjustment interface is displayed on a touch display. The first parameter adjustment interface includes an inner circular area and a surrounding area surrounding the inner circular area. The surrounding area closest to the touched first position corresponds to a first parameter value. When the object slides from the first position to a second position of the peripheral region, the touch display is switched to a second parameter adjustment interface The selected area of the second parameter adjustment interface displays the first parameter value. When the object slides from the second position to a third position along the peripheral region, the selected area is switched to display a second parameter value corresponding to the third position.

Abstract: An electronic device and an operation method of selecting a function item are provided. The operation method is applied to an electronic device. The operation method comprises the following steps: receiving a sliding instruction of a sliding path via the touch display and displaying a first pattern on the touch display. The first pattern includes the first function item or the second function item corresponding to the sliding path. A sliding track is displayed on an outer periphery of the first pattern corresponding to a sliding distance of the sliding instruction. When the sliding track meets a predetermined path, a function corresponding to the first function item or the second function item is executed by the processing unit.

Abstract: An electronic device and an operation method of browsing notification thereof are provided. The electronic device includes a body and a touch display. The operation method of browsing notification comprises: displaying a notification image on the touch display when an instruction of sliding along a first direction is received at the touch display, the notification image includes an information display area and an operation area, and the operation area includes a plurality of notification icons; displaying a first notification corresponding to a first notification icon at the information display area when the first notification icon of the notification icons receives a touch instruction at a first position; and converting to display a second notification corresponding to the second notification icon at the information display area when the touch instruction slides from the first position to a second notification icon of the notification icons at a second position.
