Google recommends wearing your Pixel 3 on a lanyard around your neck or keeping it in your front shirt pocket. From there, Lookout can tell you about people, read text, identify objects and more as you go about your day.

Patrick Clary, product manager in Google Accessibility Engineering, published a blog on Tuesday that detailed when people might need to use Lookout. The most common situations, according to Clary, would be in situations where you'd need to ask for help -- visiting a new space, reading a document or completing daily tasks.
