Basically how this method works is that it detects how close the user’s face is to the screen, and will zoom in and out accordingly. Obviously when our faces are closer to the screen, the text or image can be made smaller, and when we’re further away, the text/image needs to be bigger in order to be read. This is the first part of the patent that is called the “comfort mode”, whereby the content is maintained at a comfortable size regardless of how far away the user’s face is from the display.
The second part refers to zoom made, which is essentially the reverse of comfort mode where the closer the person’s face is to the screen, the more zoomed in it gets. This could be useful for gaming or while using maps. As expected this technology will rely on the front-facing camera to detect the distance of the user, but as to whether it will ultimately manifest itself in a future Apple product remains to be seen.
