ABSTRACT:
Systems and methods are disclosed for displaying data on a head's-up display screen. Multiple forms of data can be selectively displayed on a semi-transparent screen mounted in the user's normal field of view. The screen can either be mounted on the user's head, or mounted on a moveable implement and positioned in front of the user. A user interface is displayed on the screen including a moveable cursor and a menu of computer control icons. An eye-tracking system is mounted proximate the user and is employed to control movement of the cursor. By moving and focusing his or her eyes on a specific icon, the user controls the cursor to move to select the icon. When an icon is selected, a command computer is controlled to acquire and display data on the screen. The data is typically superimposed over the user's normal field of view.
