1. A method for providing an alternative representation of virtual content in a virtual universe, comprising the computer implemented steps of:
displaying a set of virtual universe alternative representations to a user of a virtual universe, the virtual universe including a computer-based virtual environment that a plurality of users access and interact with using avatars; receiving input from the user corresponding to a set of desired virtual universe alternative representation characteristics; defining all virtual content of the virtual universe in terms of a virtual reality modeling language, wherein the virtual content definitions comprise programming data necessary for executing objects, texts, and scripts within the virtual universe; accessing, in response to the user entering a region of the virtual universe, visual capacity information stored in a user profile associated with the user within a user database; determining a visual capacity of a user of the virtual universe based on the input from the user and the visual capacity information; providing, by a server array, an alternative representation of a virtual content of the virtual universe renderable to the user by modifying the definition of the virtual content renderable in the virtual universe with metadata that identifies how to modify the virtual content renderable in the virtual universe based on the visual capacity of the user of the virtual universe, wherein non-interactive objects are altered to appear less visually prominent relative to interactive objects, the interactive objects capable of providing a response to an interaction from the user, and wherein the modifying further includes:
annotating the definition of the scripts associated with the virtual content with metadata that identifies how to eliminate visual lighting effects from objects;annotating the definition of the scripts associated with the virtual content with metadata that identifies how to modify the color of objects; andannotating the definition of the objects associated with the virtual content with metadata that identifies how to provide simplified geometric representations of the objects; determining a second visual capacity of a second user of the virtual universe based on the input and the visual capacity information from the second user; and providing, by the server array, a second alternative representation of the virtual content of the virtual universe renderable to the second user by modifying the definition of the virtual content renderable in the virtual universe with metadata that identifies how to modify the virtual content renderable in the virtual universe based on the visual capacity of the second user, wherein an image in the second alternative representation of the virtual universe viewed by the second user is altered to appear different to the second user than the image in the virtual universe viewed than an identical viewpoint by the user appears to the user according to the alternative representation. |
