>All of us failed to do anything useful with it. We had to be told how to activate it. We had to be told what we could do with it.

If I'm going to wear something on my head like a nutcase, I would hope that it has been designed for _usability_ not _Discoverability_. Making everything idiot-proof or at least "didn't bother to read the manual proof" leaves us with only devices suited for idiots and people too lazy to read the manual.

EDIT: That said....I'm not going to wear something on my head like a nutcase, because no matter how cool it is, I'm too shy/vain/self conscious to do so. The only people willing to wear glass I would bet are people who are wiling to learn to use something to get the most benefit out of it (I would bet a huge overlap with emacs and vim users).

Devices "suited for idiots and people too lazy to read the manual" have, in the past decade, driven massive growths in computing, made it more accessible to more people, changed the landscape of the entire world, and even fueled a few revolutions.

But by all means, when people need to read a book just to use a device, we'll consider it a badge of honor instead of a failure of design.

The touch devices I assume you're referring to are intuitive because as a human you're naturally good at using your hands to make things move around.

Push a button and it acts like a button, push a thing that looks like a sheet of paper and it moves in a way that you would expect a paper on your "real" desk in front of you to move.

They're "idiot proof" because we've been trained to use them most of our lives.

Glass is something we interact with through an entirely alien interface and potentially an extremely powerful tool. I'm not talking about a podcast app, but a head mounted computer you might potentially be using for hours at a time.

Unless you eat a lot of acid, you're probably not familiar with how to interact with imaginary things that float in space before you.

To me, "they had to tell me how to use it" is a much weaker complaint than "it was easy but tedious to use" for something that sits on the side of your head.

This blog post, and the ones it links to, do a much better job of exploring this than I could here:
