Can you imagine having an instructor who peers over your shoulder all the time while you practice, say, cooking or coding? Awkwaaard. But if that's the only way you can force yourself to learn something, then this device called Grasp was made for you. It was designed to perch on your shoulder like a parrot, so an instructor can monitor and guide your every move from anywhere in the world. It has a mic, a camera and a laser pointer, all powered by an Arduino Yún board, to make real-time remote teaching more hands-on.
According to its creator, Copenhagen designer Akarsch Sanghi, he developed the tool, because "learning new skills which are more physical and instructional in nature has always been limited by the constraint of a mentor and the learner being present in the same physical space." This looks like it might have worked well with Google Helpouts, but the Hangouts-based consult-an-expert service will no longer exist after April 20th. Unfortunately, Sanghi isn't mass producing Grasp, so you'll have to check out his in-progress pics for clues if you want one of your own.
