According to Microsoft’s description of the apps and how they might work in augmented reality, “With Outlook Mail on HoloLens, you can now place your inbox on your office wall to stay on top of emails while simultaneously interacting with other digital content in your real world. You can also quickly see what’s coming up next in your day with your new wall calendar.”
Naturally this is just a small step towards a world in which we interact with our computers through a different reality. Just recently Microsoft announced their plans to open up WIndows Holographic to their partners, thus allowing them to build devices and software that would allow users to interact with their PCs using virtual or augmented reality technology.
Unfortunately since the HoloLens has yet to be released as a commercial product, its availability is in the form of the Development Edition which will cost you $3,000.
