To recap, Google Lens works by having the company’s machine learning algorithm see the world through a phone’s camera in real time. Integrating this with Google Maps allow for augmented reality (AR) additions like floating arrows pointing you to the direction you need to head to.
That said, it looks like it won’t be taking over as the standard method of using Google Maps. You can’t use the AR view consistently; the app will ask you to put the phone down after awhile. In all honesty, Google could have capitalised on this with the Google Glass, had it not been relegated to industrial use. For now, it looks like only Local Guides, or community reviewers, have access to the feature. Google says that it still needs more testing before it can be rolled out to everyone else.
