I wish this would have explained what Time of Flight means
Sorry, we were still updating the article. It has the info now. ToF is basically a laser based system that calculates the time that it takes for a laser to bounce off of objects. It should be more accurate than dot projection (aka True Depth) and it has a better range. Basically it'll make mapping indoor areas and objects better so you're going to get much better AR capabilities. Probably also some nice depth-based features for photography too.
