Abstract
An operation apparatus includes a detector that detects contact of a plurality of operating fingers on an operating surface, an area calculator that calculates an area of a detection region in the operating surface where the operating fingers have been detected, and a determiner that, after a state in which two operating fingers are detected has changed to a state in which one operating finger is detected, obtains a sum of areas of two detection regions where the two operating fingers are detected and an area of one detection region where the one operating finger is detected from the surface area calculator, and determines that an operation made by the two operating fingers is continuing when a continuation condition, in which the area of the one detection region is greater than or equal to the sum of the areas of the two detection regions, is established.
