Control method and electronic device

An electronic device, comprising:

• a housing comprising a first surface and a side surface;
• a display screen fixed in the housing and a display output area of the display screen is visible through the first surface, wherein the side surface is a whole circumferential surface surrounding the display output area;
• K Inputting apparatuses fixed in the housing, wherein the K inputting apparatuses are touch sensing units, an operation surface of each of the K Inputting apparatuses is exposed through the side surface, and the operation surfaces of the K Inputting apparatuses form a whole circle of the side surface of the housing;
• and
• a processor adapted to:
• control the display screen to display M Indicating icons on a periphery of the display screen, wherein M is a positive Integer equal to or greater than 1;
• acquire an Input operation Inputted via an Inputting apparatus of the K Inputting apparatuses, wherein K is a positive Integer greater than 1;
• determine a first Indicating icon of the M Indicating icons corresponding to the input operation;
• and
• perform a first function on the first Indicating icon, wherein the first function relates to the first Indicating icon;
• wherein when the processor determines the first Indicating icon of the M Indicating icons corresponding to the input operation, the processor is further adapted to:
• divide the whole circle of the side surface of the housing into M sub-surfaces equally;
• record a one-to-one correspondence between the M sub-surfaces and the M indicating icons;
• determine a reference point of the whole circle of the side surface;
• calculate a distance between the reference point and an operation position where the input operation is inputted along the side surface in a predetermined direction;
• determine a sub-surface corresponding to the distance;
• and
• determine an indicating icon corresponding to the sub-surface as the first indicating icon according to the one-to-one correspondence between the M sub-surfaces and the M indicating icons.
