Position Capture Input Apparatus, System and Method Therefor

摘要

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.

主权项

1. A position capture input system comprising:
a first camera configured to capture an image of a graphical user interface from a perspective of a user, the graphical user interface comprising a plurality of user interface elements; and a computing device in communication with the first camera and configured to
receive the captured image;compare the captured image to a displayed image generated by the computing device;based on the comparison between the captured image and the displayed image, determine a position of an obstruction relative to the graphical user interface; andbased on the position of the obstruction relative to the graphical user interface, determine whether a user is interacting with a user interface element of the graphical user interface.
