What the camera does is that it allows someone from a remote location to literally peer over your shoulder and guide you on what to do. This can help with all sorts of tasks that you might not be familiar with, such as cooking, fixing an engine, plugging a leaky pipe, maybe even help with homework, and more.
Grasp has a built-in camera, microphone, and a laser point which will help the instructor from the other end to point the wearer to certain things, and all of which will be powered by an Arduino Yun board. Grasp was cooked by by designer Akarsch Sanghi who felt that “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.”
The bad news is that Sanghi has no plans of mass producing Grasp, which means that if you wanted to create something similar for yourself, you’d have to head on over to Sanghi’s website where hopefully the rough sketches and idea should be enough for you to build one yourself.
