Abstract (en)
[origin: WO2019171013A1] A method for transmitting a coded light message, comprising: a step of emitting the coded message by a light emitter device (9), the coded message being emitted in the form of a series of colours emitted during regular consecutive time intervals, said message being coded by transitions between colours; a step of receiving the coded message by a light sensor (8) controlled in order to capture the colours emitted by the light emitter during consecutive time intervals and in order to thus determine the colour transitions between consecutive time intervals, representative of the coded message.
