Patent ID: 8712685

Claim:
An information processing apparatus comprising: a processor adapted to control: a position detector, wherein the position detector detects a position of the information processing apparatus; an explanation information storage device, wherein the explanation information storage device stores explanation position information which is information of a position to be explained and explanation information to correspond to each other; a generator, wherein the generator extracts the explanation information corresponding to a first explanation position from the explanation information storage device and reproduces the extracted explanation information with a sound when the first explanation position which is a position to be explained is detected within a first distance which is a predetermined distance from the position detected by the position detector; and a group determinator, wherein the group determinator determines whether or not the first explanation position belongs to the same group as a second explanation position when the second explanation position which is a position to be explained and which is a position different from the first explanation position is detected within the first distance from the position detected by the position detector after the generator starts the generating of the explanation information corresponding to the first explanation position with a sound, wherein the generator continues to reproduce the explanation information with a sound when the group determinator determines that both explanation positions belong to the same group.
