I think personally the Jill Watson assistant the professor made is very cool and actually very useful as in the article he described that students would ask the same questions and with that many students in the class answering the same questions over and over again is hard to do and very time consuming. It also served the purpose of teaching artificial intelligence to the students which is a great thing for them to know because it's a topic that is growing all the time.
VR VS AR: VR is putting us in a new world basically, disregarding what room you are sitting in or what is around you VR immerses you into a totally new world with different objects and things everywhere where AR is putting 3d graphics of different objects into our world, how we see it with our eyes but with added features like 3D shapes and models. VR is also incorporated into glasses such as Hololens and VR goggles which are now very popular. VR is now being used by healthcare professionals to help patients. A study by Duke University tested people who were disabled wore the VR headsets and moved around in a soccer stadium and this triggered the brain function associated with moving their legs and some patients after this were able to regain control. Also another great use of VR is use by dentists and surgeons who can now practice their methods in VR, allowing them to make mistakes without hurting anybody and preparing for real life situations. AR is also being used by construction workers who can plan out and map where certain parts should be built and they can use AR to see blueprints live without having to constantly look they can see it right in front of them allowing for construction to be quicker and more efficient. Another cool use of AR is learning how to cook, AR is making this easy by showing exactly how something should be stirred or flipped over and it can also even read temperatures of the food so you don't burn anything and you can simulate cooking this way so you can really perfect it. Snapchat uses AR everyday in their filters which put different animal faces and many other things to change your appearance. Niantic introduced AR with their Pokemon Go app which is suppose to promote exercise.
