I haven't watched any of the parodies on Youtube to be able to equate to what they are showing. My views are based on my research on +Project Glass
as well as research on prior technologies that some people have all but forgotten, such as virtual reality. For some reason all our attention has gone from virtual reality to augmented reality and it's been progressing.
In any case, let me focus on your comments. Being able to apply Google Glass to real world law and social context is quite simple if you look back on the patterns in technology and many of the debates going on today. We won't know how distracting Glass will be to us and how much of our visual field might be effected, but we know that it's going to be an augmented reality and will "add" to what we already see. We also don't know how new messages and data might come to our attention. If it's something that jumps out of nowhere, it can and will cause some people to be spooked and might cause problems, such as them jumping back or swerving, if worn in vehicles. Take a look at how some places have banned cell phone use of any sort while driving, some have banned texting only, and others have no laws against either. These will either be so wonderfully made that there can be no arguments as to the danger of using them while driving or we'll see lots of legal battles surrounding it. Big thing is that these would be harder to spot than somebody with a cell phone, meaning it would either call for the technology to be banned or for nothing to be able to be done. Definitely a lot to wonder about and something Google has to think ahead for. As for the social aspect...here's how it usually works:
People will buy these thinking they're going to be the best thing in the world. They'll like some of the features but they will then be highly disappointed because it's not capable of the million things they thought it could do. It will either take a while to load information, will freeze on them, might feel warm/hot where worn, won't provide apps they think should exist on it, etc. Then, given enough time, newer generations will be given and interest will keep increasing until they finally either switch to another type of technology or find a way to fully master this one.
As for legal, people are always wanting to blame something else other than themselves for something they do wrong. It's because of that sentimentality that I'm saying it wouldn't take too long before somebody blames Glass for something and then somebody tries to make them illegal to use while driving, in schools, or in lots of other places where they might be concerned about safety, privacy laws, and much more.
What I can tell you is a smaller screen has been something that has been needed for many years in order to provide the best resolution that could be worn. If they have picked up where others have failed, then +Project Glass
might have really good video resolution and could surprise me. What I'm most concerned about is the battery life. Even our best smartphones with big batteries can't last us an entire day of recording, tracking gps, making phone calls, or whatever we try doing with it. How will Glass last throughout a day?
As for your last question(s)/comment(s)...to this point most people still see Google as nothing but a search engine. Google is working hard to change that and they are making progress. We'll have to see how long until Google can expand and how quickly they can do it. Google Glass, as you already mentioned, has left everybody waiting for something spectacular. I hate to say it, but I think many people are going to be disappointed with the first few pairs in contrast to their expectations. If Google wants people to invest in this for the long haul, they better start announcing some of the flaws AND show what developers are saying positively about them. Otherwise I'm afraid that it's possible that it will be a one trick pony, where people will buy them like crazy at first and then will lose interest and lose faith in Google because it wasn't as "awesome" as they thought it would be based on videos shown and what people have imagined them to be.
That last little bit is, of course, speculation but can quickly become fact. We're just seeing good marketing right now by Google while they hide in their labs and try to correct all the flaws. I'm also going to be interested to see if Google actually releases their best version(s) right away, so it can last a person several years, or if they are going to give us a mediocre version that will "go extinct" within a year and will keep rotating as such.
Most importantly...I'm not saying people won't use them or they won't be good. What I'm saying is that Google has a lot of obstacles to overcome and that might be part of the reason as to why they are waiting so long to release them to the public. As good a company as they are, they're having to test and cover themselves when it comes to any possible damage medically, legally, and to be sure that whatever they release won't be suicide for the company.
