Visual Light Communication

( visible light between 400 and 800 THz(780–375 nm)

Light -- message

light in different frequency -- provide different function -- the “content” of any medium is always another medium?

low frequency to high frequency -- visible to invisible

light bulb (lighting)
lighthouse, sos light (three times short, three time long)
Flicker/Dreamachine/(Stroboscope: initially be used to measure motors)
detection: Optical mouse
VLC(Visible light communication): ByteLight / Lifi (works by switching bulbs on and off within nanoseconds)

"The electric light is pure information. It is a medium without a message, as it were, unless it is used to spell out some verbal ad or name. This fact, characteristic of all media, means that the “content” of any medium is always another medium." -- McLuhan
