1. An information processing apparatus, comprising: circuitry configured to detect an interaction area of a position detection surface specified by a single static point of contact on the detection surface by a manipulation object; calculate a predetermined shape as a region corresponding to the interaction area based on the single static point of contact, determine a plurality of focused targets that overlap the predetermined shape; display a subset of the plurality of focused targets determined based on a distance between each of the plurality of focused targets and a center of the predetermined shape, in a window that overlaps an input field and that has a same number of rows above and below boundaries of the input field, the window not overlapping the interaction area, the input field being separated from the interaction area, the subset of the plurality of focused targets being fewer than all of the plurality of focused targets; determine a selection candidate from the plurality of focused targets; and emphasize the selection candidate relative to others of the plurality of focused targets, wherein the plurality of focused targets include alphanumeric characters, said circuitry displays the selection candidate as an alphanumeric character emphasized, as compared to others of the plurality of focused targets, by at least one of an insertion-point cursor and bold text, and the window in which the plurality of focused targets are displayed moves when the selection candidate is selected.
