For this app, you are using a 3D ball to make into a basketball hoop with just your finger. We used sensors like ambient light sensors, so it can detect changes in the environment and send it to the CPU allowing you to still play the basketball game. Sound sensors are used so you can be hearing the basketball being dribbled and the sound of the basketball hitting the rim and backboard. Orientation is also used to determine the relative position of something or someone. Also a touch sensor is used to allow you to drag the ball and flick it into the basket when you are shooting. Finally a gravity sensor is also used for the basketball to actually go in the hoop and eventually go down when it is shot. The camera plays a very big role when playing the app. When you are using the app, the camera will detect your environment and place the basketball hoop wherever, in the area you are in. The camera is also what makes the game AR so it will allow us to play anywhere in 3D.
