For your initial post, select a more complex input device such as a touchscreen, glove sensors, eye input, audio or voice input, a joystick, or anything else. Then, answer the following:

• Where might the input device you selected be used? If possible, find an actual application where a different input device is used to control OpenGL objects or run applications that use OpenGL.
• Can you identify the libraries that would be necessary to run the input device?
• What challenges do you think you would encounter when navigating around the world using the input device? For example, if you are using a glove to move forward, your arm will only extend so far or your hand might come in contact with the view screen.
• What other considerations for the use of this input device can you identify? Think about accessibility, cost, set-up, and size as a few possibilities.
