An example of a design item which uses top-down visual processing is a faucet. This fixture requires the user to decide how to use it in a quick fashion. When a user operates the faucet, he/she must devote attention to object, and there must be priming of the plan of use. One must look whether he/she wants hot or cold water (which is present in the left and right handles, respectively), and they must point the spout in the direction they want the water to go. This object is fairly self-explanatory, and performs a simple function with little attention given. This is an example of competent industrial design with respect to top-down visualization, due to the fact that it is simple to use and performs its function well, while also being aesthetically pleasing.
