We live in very exciting times. Technology is changing at a pace so rapid that it is becoming near impossible to keep up with these new frontiers as they arrive; they seem to arrive on a daily basis now. Moore's Law continues to stand, meaning that technology is getting smaller and more powerful at a constant rate. As I said, very exciting.
One of these new emerging technologies that finally is reaching a place more material than science fiction stories is Augmented or Mixed Reality. Imagine a world where our communication and entertainment devices are worn, and the digital tools we use, as well as the games we play, are holographic projections in the world around us. These holograms know how to interact with our world and change themselves to fit our needs. Microsoft has led the charge by releasing such a device: the HoloLens.
The Microsoft HoloLens changes the paradigm of what we know as personal computing--we can now have our Word window up on the wall (this is how I am typing right now), we can have research material floating around it, and we can have our communication tools, such as Gmail and Skype, in the area as well. We are finally no longer trapped by a virtual desktop, on a screen, sitting at a physical desktop; we aren't even trapped in the confines of a room anymore.
