Abstract: Multiple projection input devices may be permanently attached or temporarily attached to a display device. Each projection input device may project, using one or more projectors, a representation of an input device on a work surface, receive video data from one or more cameras, identify one or more fingers interacting with the representation of the input device, track a motion of the one or more fingers relative to the representation of the input device, predict, using a machine learning algorithm and based on tracking the motion of the one or more fingers relative to the representation of the input device, a particular input being provided, and transmit the particular input to a computing device. The representation of the particular input device may include a representation of one of: a keyboard, a mouse, a trackpad, a numeric keypad, a trackball, or a gaming controller.
