AI also can drive productivity for employees in stores. One new technology, Theatro, allows employees at large retailers to access an AI-powered virtual assistant with their voice to gain information about the store almost instantaneously. Someone working on the floor at Home Depot in Canada has the ability to connect a Theatro device to an artificially intelligent virtual assistant that talks to her through an earpiece. The assistant can help her understand things like inventory and back-of-the-house operations, so that more employees can be on the floor working with customers instead of physically searching for answers in outdated systems in the back of the house.
