More Information
Summary:A system includes an image capturing device, a user input device, and a processor coupled to the image capturing device and user input device. The processor includes instructions for capturing a data image with the image capturing device. The data image includes a signal from the user input device. The processor further includes instructions for deactivating the signal from the user input device and, after deactivating the signal from the user input device, capturing an ambient image. The processor further includes instructions for subtracting the ambient image from the data image and determining a position of the user input device in a three-dimensional space using a result of the subtracting.
