Abstract: An object is to provide an input support apparatus, a method of input support, and a computer program that can appropriately perform feedback to a user when a noncontact operation is performed without using a controller. The present invention continuously acquires space coordinates of a certain part of a user via a detector and, based on the updated space coordinates, performs display control to move a marker to a corresponding position on a display screen of a display unit, where an initial shape of the marker includes a plurality of shapes obtained by dividing any desired shape, and display control is performed that separates the shapes more widely from each other from the corresponding position on the display screen as a distance of the space coordinates to a certain plane in a coordinate system of the space coordinates is longer and brings the shapes closer to each other to the corresponding position on the display screen as the distance is shorter.
