A good example of a use case on reading, whether it’s the autoscroll in a web page or autoscroll in a book, is on a train. Lots of people in this world commute, and they read with one hand while they’re coming into the office. With traditional sensors, a phone does not know the difference between the movement of the train and the movement of your hand. You hit a bump, it’s going to think your hand moved. But what we can do is we can track the phone relative to your head. And so all of the externalities that might happening—it might be your car moving or a train moving–we can then isolate out of that so the autoscroll can be a smooth and seamless reading experience with one hand while you’re hanging onto the rung of your subway car.
