I don't think this device alone would make this big difference. we already have phone that are able(especially with the cloud) to do augmented reality. In many use cases we don't need this immediate response. we can "take the time" and get our smartphone.

We point our phone at that product, or at our lunch, or at the home diy project we need to do, or at some hobby we're doing, or at the car repair we're doing. we don't need glass for that.
