>> SMART - THE DANCING RED LIGHT
It is always welcoming to have a great way to introduce IoT to the common folk.
manufacturer) pulled of a very interesting
campaign in Lisbon, Portugal to
provide a fun and safe way to prevent people from crossing the road on a
red signal - which has been identified as a main source of road related
accidents. The catch? random pedestrians were invited into a box to dance
and their actions were displayed on a few traffic lights in real time.
The outline of the dancer was captured using a video camera and then
digitized into what seems to be a 32x32 LED matrix showing the respective
outline - complete with a video feed from the cameras to see the reactions
of the public in real time. It was obvious the reactions from the audience
caused some dancers to be a little creative in their moves.
It would be interesting to know exactly how the team integrated such
modifications; my guess would be the use of a series of high powered
micro-controllers like the
Raspberry Pi, networked together and connected to a LED matrix component to
transmit the digital bitmap - they did post a
making of video however didn't release details on the hardware.
The net result?
81% more people stopped and waited for the green signal - at least until
it gets boring.
