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.

A detection system for monitoring a subject remains outside the normal field of view of the subject by using a wavelength selective optical member. In one application, an eye of a driver is repeatedly or continuously illuminated and imaged without effect on the field of view of the driver. A dichroic mirror may be used to provide the wavelength selectivity. For the application in which the system is used for a motor vehicle, such as an automobile, the dichroic mirror may be achieved by coating a portion or all of the windshield so as to pass visible light, while reflecting detection light. Other applications of the detection system include monitoring a subject engaged in a person-to-person interaction, wherein a dichroic mirror is defined by a divider between the two persons.
