Specifically, for the current column item of the current list a, a1, whose center point is a-C1, then for the downward neighboring list, i.e. list B, the distances between the center points B-C1, B-C2, B-C3, … of each item in list B and the center point a-C1 of the item where the current focus is located are calculated, the item with the shortest distance to the center point a-C1 in list B is found, and this item is taken as the downward focus item nextFocusDown of the current column item a1, and assuming that the item with the shortest distance to the center point a-C1 in list B is B1, the nextFocusDown Id of the current column item, e.g. a1, is set as Id of B1. Likewise, for the adjacent list in the up/left/right shift direction, the calculation obtains the up focus item nextfocusUp/left focus item nextfocusLeft/right focus item nextfocusRight of the current list item.
In step S2, when the focus movement control command is received, the current list where the current focus is located and the list item location of the current focus in the current list are determined, and the movement focus item is determined.
