Information processing apparatus and image forming apparatus

摘要

An image forming apparatus 1 of the present disclosure has a display unit 162 capable of displaying a plurality of objects such as small images and a touch detection unit 164 which meets multi-touch, these units being formed on an operation panel unit 6. A touched shape determination unit 81 calculates a touched area from touch coordinates detected by the touch detection unit 164. Then, the touched shape determination unit 81 calculates a touched shape like line strip from the touched area. A selection area setting/moving unit 82 calculates an object selection area which is a closed touched shape and selects and moves all objects which overlap the object selection area.

1. An information processing apparatus comprising:
a display unit configured to display a plurality of objects; a touch detection unit configured to detect a plurality of touch coordinates on the display unit; a touched shape determination unit configured to calculate a touched shape from the touch coordinates detected by the touch detection unit; and a selection area setting/moving unit configured to: calculate an object selection area that represents a closed area for a case where the touched shape is in a hook-like shape, and have an aggregation mode which selects and moves all objects that overlap at least partly the object selection area, wherein if the touched shape includes a predetermined portion which deviates in a concave or convex direction from a line connecting two end points of the touched shape, the selection area setting/moving unit is further configured to: determine that the touched shape is in the hook-like shape; calculate the closed area in which both ends of the touched shape in the hook-like shape are connected to each other as the object selection area which is an approximation of an area touched by a user when the touch detection unit detects the user having touched the display unit with a finger in a hook-like shape; and set automatically the aggregation mode and move an entirety of a plurality of objects when the plurality of objects is selected by the selection area setting/moving unit, and wherein if the touched shape is like a dot or substantially a straight line, the selection area setting/moving unit is further configured to: determine that the touched shape is not in the hook-like shape; and select and move at least one of a plurality of objects which is displaced at a highest location on a surface the display unit when the touched shape overlaps the plurality of objects.
