An application which is mainly oriented with engineers and do it yourself type of work. The first thing is to get the maximum hand stretch of the glass user. If the glass camera has depth sensor, then we can even skip this step. Once that is set, after that any object that he holds at that distance we can use image recognition to find the different metrics of the object by giving length, breadth and height of the object(plank of wood or any hardware). If we can identify the object lets say its a small circuit board or a chip we can give all the pin information of the chip.
