Method and apparatus for tool selection and operation in a computer-generated environment
Method and apparatus for facilitating virtual object selection and interaction in a computer-generated environment such as a virtual or augmented reality 3-D environment are disclosed. A physical controller allows interaction by the user with a tool displayed at a first position in the computer-generated environment where, when a first signal is received from the physical controller to initiate selection of the tool, a visual cue is created in the computer-generated environment. The visual cue includes a vector that allows targeting of the tool and is displayed with respect to a virtual controller that is a graphical representation of the physical controller in the computer-generated environment. Upon receipt of a selection signal from the physical controller when the vector and the tool intersect, the computer-generated environment is updated to display the tool at a second location that is relative to the virtual controller.
