When you need to pee and you enter a public restroom, which urinal do you choose? The urinal simulator is used to simulate men's choice of standing when they go to the toilet to urinate. The system will give you 6 sets of scenes to choose which urinal you want to use, and the system will display the user's choice and how many people are the same after the user has made a choice, and give a final score by combining the 6 sets of tests.
