Abstract
Embodiments of the invention may be used to enhance the presentation of a virtual environment for certain users, e.g., a visually impaired user. Because users may visit, and revisit, locations within the virtual environment, the state of elements in the virtual environment may change. Accordingly, audible descriptions of an object, person or environment, may be adjusted to prevent redundant or unnecessary descriptions. For example, when the user encounters a given element a second time, rather than describe each characteristic of the element, only changes to the characteristics of the element are described.
