Abstract

A virtual computer monitor is described which enables instantaneous and intuitive visual access to large amounts of visual data by providing the user with a large display projected virtually in front of the user. The user wears a head-mounted display containing a head-tracker, which together allow the user to position an instantaneous viewport provided by the head-mounted display at any position within the large virtual display by turning to look in the desired direction. The instantaneous viewport further includes a mouse pointer, which may be positioned by turning the user'"'"'s head, and which may be further positioned using a mouse or analogous control device. A particular advantage of the virtual computer monitor is intuitive access to enlarged computer output for visually-impaired individuals.
