Homo sapiens are visual creatures. We receive 75% of our information through our eyes. Explaining how to do something can be tedious and inefficient. Augmented reality offers a visual medium for explanation. This quick demo on how to assemble a LEGO tower using ARToolKit illustrates how effective this technique can be. If you don’t believe me, give a friend a pile of LEGOs and then try to explain how to create the tower in the video. Time your result and compare it. I’ll guarantee the AR method will win.
