AP EXCLUSIVE: at Walmart, Using AI to Watch the Store

The thousands of cameras are a key feature of the lab, which officially opens inside this 50,000-square-foot store on Thursday. Walmart envisions using them, combined with other technology like sensors on shelves, to monitor the store in real time so its workers can quickly react to replenish products or fix other problems. The technology, shown to The Associated Press, will also be able to track when shelves need to be restocked or if shopping carts are running low. It can spot spills on the floor and even detect when cash registers need to be opened up before long lines start forming.
