	Head-mounted display - Wikipedia, the free encyclopedia
		Head-mounted displays may also be coupled with head-movement tracking devices to allow the user to "look around" a virtual reality environment naturally by moving the head without the need for a separate controller.
		A head-mounted display (HMD) is a display device that a person wears on the head to have video information directly displayed in front of the eyes.
		An HMD has either one or two small LCD or OLED displays with magnifying lenses embedded in a helmet, glasses or visor.

	Head-Up Display - Wikipedia, the free encyclopedia
		Head-Up displays were pioneered for fighter jets and later for low-flying military helicopter pilots, for whom information overload was a significant issue, and for whom changing their view to look at the aircraft's instruments could prove to be a fatal distraction.
		A Head-Up Display, also known as a Heads-Up Display or simply HUD, is any type of display that presents data without blocking the user's view.
		Helmet-mounted, or head-mounted, in which the display element moves with the user's head.

	Re: how does a Head-Up Display (HUD) works on the aircraft?
		Several types of HUD displays for aircraft are presented on the Kaiser Aerospace Company web pages at: http:// www.kaiseraerospace.com/products.htm More recently helmet integrated displays (HID) have been developed so that the users can read instruments while turning their heads to view the world.
		These displays are mounted on an instrument panel below the level of the wind screen (wind shield) and pilots have to take their eyes off the outside environment and lower and refocus their vision to read the meters, dials and indicators.
		Two CRT or liquid crystal display (LCD) systems (one for each eye) are being developed to provide 3D stereoscopic display of information to the pilot.

	EYEGLASS HEADS UP DISPLAY
		The application of the display for a helicopter-pilot heads-up-display (HUD) and as an aid for the deaf is also presented.
		Since the display for the pilot HUD application has relatively few "on" pixels, the display refresh time is improved by simply erasing (loading 0's to the display RAM) only for the previously illuminated pixels instead of the entire display.
		The image is generated by a miniature display generator, in the bow of the glasses, which uses a vibrating fiber-optic ribbon attached to a linear light emitting diode (LED) array.

		Cockpit design is leaning more and more toward multifunction displays, or MFDs, capable of providing the same HUD display in an alternate, head-down manner when necessary or desired.
		Summing up, the F-16 provides you with sufficient reliability, redundancy, and failure monitoring to use the HUD in any weather with the confidence that you know and understand the state of your airplane and the status of its equipment.
		Although a degree is always a degree, it appears that the angles displayed on the HUD are much larger than you’re accustomed to on the normal ADI.

	Head up display system - Patent 4669810
		In conventional holographic head up displays, a "relay lens" system is used to project the desired symbology toward the holographic combiner at an angle relative to the combiner, with the relay lens system being provided with aberration correction features compensating for the aberrations resulting from the off-axis projection angle.
		1 illustrating a head up display 10 in accordance with the present invention, a first holographic optical element or combiner 12 is positioned between the pilot's eye position 14 and the aircraft windscreen 16 so that the pilot's line of sight 18 extends to the outside scene through the combiner.
		The present invention relates to head up display systems and in particular to a head up display system wherein flare or multiple images are minimized and a substantially aberration-free display is presented.

	ABC Radio National: The Buzz 15 December 2003 - Safer Driving - Head Up Display
		The Head Up Display is just a medium but we have to think about the contents of the information that we want to convey so we want to make sure that the information that we push from the laptop is appropriate to a particular situation.
		There was some study that compared the use of Head Up Display with display next to the radio and they figure out that that the driver acquire those information in a quicker manner.
		And the second potential problem is that when you use the Head Up Display you tend to look at it, meaning that it will have an effect on visual attention to outside object.

	Head Up Display
		The new head up display (HUD) projects information off of the windshield in a way that it appears to be floating in front of the driver.
		Now, new virtual technology is putting driver information in front of the windshield of a car, so that drivers can keep their eyes on the road while they flip the radio dial or find out how much gas they have left.
		And not only do HUDs make driving safer, they also help drivers manage the growing amount of information they receive.
