A few months ago, NYC Mayor
Just last night, the city announced the six winning prototypes. Some of the submissions imagined payphone kiosks with air pollution sensors, solar-powered cell phone chargers, and screens controlled by hand gestures and voice commands.
The city judged the prototypes based on connectivity, creativity, visual design, functionality, and community impact.
New York City's contracts for its payphones expire in October 2014. The winners of the Reinvent Payphone Design Challenge aren't guaranteed contracts, but the city will take those designs into consideration when determining what to do with New York's payphones.
Already, the city has converted some payphones into Wi-Fi hotspots. And in November 2012, it replaced 10 booths in Union Square with touchscreens for maps, public service announcements, and entertainment listings.
