| 发明名称 | Information communication method | ||
| 摘要 | An information communication method is provided that transmits a signal using a change in luminance. The information communication method includes determining a pattern of the change in luminance by modulating the signal to be transmitted, and transmitting the signal by a display, which is a light emitter, changing in luminance according to the determined pattern. The method also includes detecting, by a sensor, a person within a viewing angle of the display or a person near the viewing angle. Further, in the transmitting of the signal, the signal is transmitted by changing in luminance by a larger change amount in the case where the person near the viewing angle is detected than in the case where the person within the viewing angle is detected. | ||
