Pedestrian-mounted Brake Lights and Turn Signals??
At first glace, the upcoming Augmented Human International Conference ’13 in Stuttgart looks to be an attempt of Japanese researchers to troll the science community with a Chindogu–Japanese “unuseless” invention: Brake lights for your butt.

The Journal of Improbable Research today offered links to a great story: Pedestrian-mounted brake lights: March 8 in Stuttgart (Improbable Research–blog | 2013/02/27).
At the “Augmented Human ’13” conference, Japanese researchers, Hiroaki Sasaki, Tsutomu Terada and Masahiko Tsukamoto will present: A System for Visualizing Human Behavior based on Car Metaphors (link). The researchers will,
propose a system for visualizing the user context by using information presentation methods based on those found in cars, such as wearing LEDs as brake lights, which can be seen by surrounding people.
Ri-i-i-ight.

As fat as your ass is Taro, you need, “Brake lights for your butt.”
I’ve already got that covered.
Besides the butt brake lights, check out the other fun Japanese presentations at the AUGMENTED HUMAN ’13 conference.

the more days goes by…
the more i think brake lights should be forbidden at least during the day and replaced by always on rear drls…
Stop lights allow people to pay as little attenshion as possible to the traffic since they can catch them lighting up with their peripheral vision while doing pretty much anything except driving…
Automatic gearbox should follow them to the grave… ever tried putting on makeup with a stick shift ?
I prefer just mowing over the idiots who randomly stop in the middle of a brisk walk through a crowd. Same as I elbow all the assholes that crowd in front of the doors when I’m trying to exit the train.
Ouch, that fornicating hurts…
The droll Japanese news graphic reads:
Mo’ betta butt signals…
