We’re not quite at the stage of all being cyborgs, but the wearable computing market is growing, and the number and type of devices is also increasing.
One form in particular that has a great deal of potential for many hands-free uses is the HUD (Heads Up Display) mounted in the form of goggles or glasses.
These types of wearables already come in a variety of shapes and sizes, from as light as the Google Glass to the more bulky Oculus Rift (which was acquired by Facebook in Mar 2014 for $2B). The Rift isn’t exactly something you can use in everyday activities, given its form factor and that it covers half your face. However, the Google Glass is lightweight and seems almost unobtrusive. It also has a lot of uses for education — be it for grade school, high school, college, or beyond.
