User interface based interaction method and related apparatus

An electronic device, comprising:

• a display unit, configured to display a user interface;
• and
• a focal point moving unit, configured to:
• when a level i focal point stays in a level i area X of the user interface, if an instruction for moving a level i focal point is received, in response to the instruction for moving a level i focal point, move the level i focal point from the level i area X of the user interface to a level i area Y of the user interface, wherein the level i area Y comprises an interface element a and an interface element b, and
• when the level i focal point stays in the level i area Y of the user interface, if an instruction for moving a level i+1 focal point is received, in response to the instruction for moving a level i+1 focal point, move a level i+1 focal point from the interface element a in the level i area Y to the interface element b in the level i area Y.
