Display device displays on display surface email composing screen SC1 that includes selectable objects. When a proximity operation that indicates object b1 is detected, display device sets a selection of object b1 to valid and sets a selection of surrounding objects b2 to b5 (objects represented by diagonal hatching in FIG. 6B) to invalid.
