POSITIONING SUPPORT APPARATUS, POSITIONING SUPPORT METHOD, AND PROGRAM

A positioning assistance device that assists positioning between a content displayed on a display and an object transparently observed through the display is as follows. The positioning assistance device includes: a state calculation unit configured to calculate a supported state of the display relative to the object; an adjustment amount calculation unit configured to calculate, for the supported state, an adjustment amount related to a positioning operation for setting an appropriate positional relation between the content and the object; and a presentation information generation unit configured to generate and output presentation information including the adjustment amount. The adjustment amount calculation unit calculates the adjustment amount by using record data of a positioning operation performed by a user of the display in response to the presentation information output in advance.
