Isn't it much easier to just look into your refrigerator/pantry and keep a mental track of things? There are a few pitfalls to your suggested method: * It takes a good amount of time scanning and cataloging everything and we are taking about a world where people don't find enough time to scribble down these things on a piece of paper. * What if you pulled out cereal box A and cereal box B but switched places when putting them back? * Since its scanning the boundary of objects, it won't be able to tell you if your Milk is empty, half empty or full. The one thing I could think of where this is useful is in scanning rooms/objects which are for sale. Like 3d scanning the bike you are going to sell, or a realtor using it to provide a virtual 3d tour of a house. However, Microsoft already did it with their Photosynth program and regular photos you take [1], so I am not sure how this is going to fair if it turns out to be expensive.
