* Starred: Augmented reality applications (the rest is just 'camera')
Glasses or watch?
iWatchMeanwhile , Apple is working with 100 designers on the iWatch, list to data a smart watch. Star Trek without 'Beam me up, Scotty'. It stands to reason that the iWatch will also offer many of the functions of Google Glass: alerts, information, apps and perhaps a short meeting, without having to take your phone out of your pocket. More possibilities than the Pebble, but no augmented reality and no 'first person' video like with Glass.
The iWatch and Google Glass are both ' wearable devices ': the functions of a smartphone always and even closer to you. I expect that many people will choose the iWatch rather than Glass. The iWatch also offers information at a glance and the advantages of the video function of the glasses do not yet outweigh the (social) disadvantages. And if you go skiing or ski diving you can also put on a - much cheaper - headcam .
If Google Glass does break through, because enough people benefit from it every day, then our lives will fundamentally change. When we meet each other, with Glass, the first question we ask each other is: "Hello, are you alone?"
