Abstract: According to various embodiments, a position capture input system uses a camera to capture an image of a displayed graphical user interface that may be partially obstructed by an object, such as a user's hand or other body part. The position capture input system also includes a software component that causes a computing device to compare the captured image with a displayed image to determine which portion, if any, of the graphical user interface is obstructed. The computing device can then identify any user interface elements with which the user is attempting to interact. The position capture input system may also include an accelerometer or accelerometers for detecting gestures performed by the user to, for example, select or otherwise interact with a user interface element. The position capture input system may also include a haptic feedback module to provide confirmation, for example, that a user interface element has been selected.
