Abstract:
An information processing program causes a computer to execute: encoding information to be transmitted, to determine a luminance change frequency; and outputting a signal of the determined luminance change frequency to cause a light emitter to change in luminance according to the determined luminance change frequency to transmit the information. In the encoding, each of a first frequency and a second frequency different from the first frequency is determined as the luminance change frequency. In the outputting, each of a signal of the first frequency and a signal of the second frequency is output as the signal of the determined luminance change frequency, to cause the light emitter to change in luminance according to the first frequency during a first time and change in luminance according to the second frequency during a second time different from the first time after the first time elapses.
Abstract:
An information communication method for obtaining information from a subject includes transmitting position information indicating a position of an image sensor used to capture the subject, and receiving an ID list that is associated with the position indicated by the position information. The method also includes setting an exposure time of the image sensor so that a bright line corresponding to an exposure line included in the image sensor appears according to a change in luminance of the subject. The method further includes obtaining a bright line image including the bright line by capturing the subject that changes in luminance by the image sensor with the set exposure time, obtaining the information by demodulating data specified by a pattern of the bright line included in the obtained bright line image, and searching the ID list for identification information.
Abstract:
A visible light communication method transmits a signal by visible light communication. The visible light communication method includes modulating the signal into a predetermined blinking pattern, and transmitting the signal by causing visible light to blink according to the predetermined blinking pattern and toward a wall, from a projector disposed in an indoor space surrounded by the wall. The visible light communication method also includes projecting video from the projector toward the wall, wherein the visible light is reflected by the wall to prevent the signal from being received outside of the indoor space, and the signal is used to transmit data related to the video projected to a terminal in the indoor space.

Abstract:
A lifting system includes an unmanned aerial vehicle, a thruster device, a first wire, a first reel, a second thruster device, a second wire, a second reel, and a controller. When the unmanned aerial vehicle is in a position separated from the ground, the controller detaches the first thruster device and the second thruster device from the unmanned aerial vehicle, causes the first reel to reel out the first wire, detaches the second thruster device from the first thruster device, and causes the second reel to reel out the second wire.
