Speaking about augmented reality, Apple CEO Tim Cook said he believes this technology will have as big as an impact as the App Store. However, he doesn't believe the industry is ready yet for AR goggles or glasses. Cook stated the technology required to deliver a qualitative wearable AR experience simply doesn't exist yet.
In particular, Apple's boss points to the immaturity of the display technology, which doesn't have a high enough quality nor field of view, as well as the issue of putting low-power hardware with enough processing power around your face:
Cook didn't address all of these technical differences in the interview, but he did talk about the prospects for AR goggles or glasses. He believes the tech isn't ready:
The technology itself doesn't exist to do that in a quality way. The display technology required, as well as putting enough stuff around your face–there [are] huge challenges with that. The field of view, the quality of the display itself—it’s not there yet.
