> Wearables, ultimately, are an expiremental product. Neither the users not the developers really know what the application is. I think we know what the killer applications are, and the problem is that the killer apps for wearables (especially glasses type devices) have deep societal/ethical concerns. The apps that would sell well are mostly "situational awareness" for law enforcement, sales (used car credit checks before rep engages), venue security (don't let people with records/bad social credit in), etc... Connecting face recognition, credit/background checks and putting that at the point of sale or entry. Unfortunately, it's coming. I'm not sure this is going to make the world better. BTW - UI, design and all of that really matters less than you would think if the application has great utility and benefit (to the wearer/wearer's employer). The problem is a lot of the apps I've seen don't really do anything that is all that remarkable or useful enough to make your "greeters" wear them.
