Tech-Infused Playgrounds Liven Up Public Spaces [Pics]
"Living Innovation Zones" give companies a chance to showcase their latest work in San Francisco.
The city of San Francisco has partnered with the Exploratorium, a science-education museum that’s geared toward children, to make public spaces more interesting in areas that are frequented by office workers and tourists. One of the most popular exhibits is a pair of satellite dishes that encourage people to whisper into them. The dishes are actually parabolic acoustic amplifiers, which can amplify a whisper so that it’s loud enough for someone else to hear 50 feet away.
