Apparatus and methods of displaying messages for electronic devices

摘要

An apparatus of transmitting messages from an electronic device and display it on a mobile device, and a method of doing the same are disclosed. An exemplifying electronic device has an encoder to encode the data and a drive to modulate the signals into temporal and spatial light patterns according to the transmitted message. The light signals are then emitted from a group of LEDs on the electronic device. A video camera on a mobile device captures the light signals in the form of temporal and spatial patterns. A software application decodes the message and displays the message on the mobile device screen.
