Artificial intelligence drives next-generation street sign

Smartphones and GPS have made paper maps virtually obsolete and put the power of navigation in our pockets. But now, engineers are working on a high-tech update for another directional tool that could revolutionize how we find our way around. The first street signs date back hundreds of years. They help you figure out where you are and where you're going. But what if they could be updated throughout the day, hour by hour to keep you informed about what's happening around you? "This is a fully-functioning street sign that allows you to essentially market, advertise and communicate out to the public," Michael Ottoman said, showing off a hi-tech version of the old street sign.
