Abstract: A three-dimensional space is defined and displayed in a main window of a computer display. Navigation through the three-dimensional space occurs by user inputs correlated to the three-dimensional display of the space from the user's point of view within the space. Navigation also occurs from user inputs correlated to a secondary two-dimensional display of the user's position relative to two dimensions of the three-dimensional space. A three-dimensional environment defined by the space displays computer resource icons. Activation of a computer resource is achieved by navigation through the three-dimensional environment and selection of a displayed resource icon through manipulation of an input device. Resource icons may be displayed in the environment in various predetermined three-dimensional configurations to signify hierarchical relationships between the associated computer resources.
