This next prototype isn’t so much about not getting in the way, but it is about making sure you don’t overfill a single screen. I use the example of the Snellen Eye Chart. In my experience, about five percent of folks trying on Glass for the first time have trouble seeing the display. First there is the question of which eye may be dominant. Then there is whether they wear glasses or not.

If you need glasses to see a 25 inch diagonal display 8 feet away, then you need to look through your eye glass to see the smaller fonts, down to 26 pixels in font size. So I created this mockup of Glass Eye Chart. When someone puts on Glass I ask if all the text is legible, or if not, what is the smallest font that is legible. This is useful for “seeing” if Glass is for you. I can imagine it might be useful for developer. Or, swiping from this card to the next card might lead to a map of nearby optometrists and eyeglass shops catering to glass.
