Abstract
An information communication method selectively obtains a location of a terminal device. Determining the location of the terminal device by wireless communication with a wireless access point includes receiving a radio signal including a first identification information to identify a location of the wireless access point, and calculating the location of the terminal device using the identified location of the wireless access point, which is identified by the first identification information. Determining the location of the terminal device by visible light communication with a subject provides higher accuracy and includes setting an exposure time of an image sensor having a plurality to exposure lines so that a bright line corresponding to each of the plurality of exposure lines included in the image sensor appears according to a change in luminance of the subject, obtaining a bright line image by capturing the subject, and demodulating data from the bright line image.
