Viewpoint control of a display of a virtual product in a virtual environment

摘要

A method, system, and apparatus for visually presenting a virtual environment relative to a physical workspace. An output device visually presents a view of the virtual environment to guide a human operator in performing a number of operations within the physical workspace. A mounting structure holds the output device and is movable with at least one degree of freedom relative to the physical workspace. A sensor system measures movement of the output device relative to the physical workspace to generate sensor data. A controller computes a transformation matrix and the set of scale factors to align the virtual environment and the physical workspace. The controller changes the view of virtual environment based on the sensor data to thereby change the view of the virtual environment in correspondence with the movement of the output device relative to the physical workspace.

1. An apparatus for visually presenting a virtual environment relative to a physical workspace, the apparatus comprising:
an output device that visually presents a view of the virtual environment to guide a human operator in performing a number of operations within the physical workspace; a mounting structure that holds the output device and that is movable with at least one degree of freedom relative to the physical workspace; a sensor system associated with at least one of the mounting structure or the output device, wherein the sensor system measures movement of the output device relative to the physical workspace to generate sensor data; and a controller that computes a transformation matrix and a set of scale factors to align the virtual environment and the physical workspace, wherein the controller changes the view of the virtual environment based on the sensor data, the transformation matrix, and the set of scale factors;
whereby the controller changes the view of the virtual environment in correspondence with the movement of the output device relative to the physical workspace.
