Among the hassles you deal with at sports events, waiting in line is one of the most annoying. What if you miss the start of play because you had to satisfy a hot dog craving? The Indiana Pacers want to alleviate that headache. They're partnering with tech startup WaitTime to shorten waits through artificial intelligence. The newly-launched system takes photos of arena lines at a rate of 10 times per second, and interprets that data to gauge not just queuing times, but also order completion times and the number of people who've given up. The Pacers display the wait times on screens and a mobile app to show you where wait times are short -- you'll know that a given washroom is empty, or whether it'd be quicker to grab nachos instead of a burger.
