Sky Deutschland Considering Using Bone Conduction To Force Ads On Train Riders
KindMind writes "Sky Deutschland is considering a proposal to use bone conduction to broadcast ads to train riders. The idea is that the riders rest their heads against a part of the train, like the train window, and then bone conduction would broadcast ads directly into their ears."
We can't really let this thread go on without mentioning São Paulo. Looks like the experiment is going well too.
