Abstract: Various implementations for detection and virtualization of tangible interface object dimensions include a method that includes capturing, using a video capture device associated with a computing device, a video stream of a physical activity scene, the video stream including a first tangible interface object representing a measurement attribute, identifying, using a processor of the computing device, the measurement attribute of the first tangible interface object, determining, using the processor of the computing device, a virtual object represented by the measurement attribute of the first tangible interface object, and displaying, on a display of the computing device, a graphical user interface embodying a virtual scene, the virtual scene including the virtual object.
