This document summarizes head-up display (HUD) technology used in automotive and helmet applications. It discusses the key components of an HUD system including a projector unit, combiner, and video generation computer. The projector unit produces a collimated image and the combiner reflects the monochromatic light. HUDs first appeared in cars in the late 1980s and now provide speed, navigation, and night vision information. Experimental helmet HUDs use the visor as a display and include sensors to track head movement. Components include a micro display, electronic board, battery and connectivity for augmented reality navigation aids.

2. Eye-cue
 Eye-cue is commonly called as Head-Up Display (HUD)
 It is an transparent display that presents data without
requiring users to look away from their usual viewpoints.
 The origin of the name stems from a pilot being able to
view information with the head positioned “up” and
looking forward, instead of angled down looking at lower
instruments.

3. Components in an HUD
 A projector unit,
 A combiner,
 and a video generation computer.

4. The Projector unit
 The projection unit is an optical collimator setup: a
convex lens or concave mirror with a cathode ray tube,
light emitting diode, or liquid crystal display at its focus.
 This setup produces an image where the light is
collimated, i.e. the focal point is perceived to be at
infinity.

5. The Combiner
 The combiner is typically an angled flat piece of glass (a
beam splitter) located directly in front of the viewer.
 Combiners may have special coatings that reflect the
monochromatic light projected onto it from the projector .
 In some layouts combiners may also have a curved
surface to refocus the image from the projector.

6. The Video generation computer
The computer provides the interface between the HUD (i.e.
the projection unit) and the systems/data to be displayed
and generates the imaginary and symbology to be
displayed by the projection unit.

7. Timeline
 1988: General Motors began using head-up displays. Their first HUD
units were installed on Oldsmobile Cutlass Supreme Indy Pace Cars
and replicas. Optional HUD units were subsequently offered on the
Cutlass Supreme and Pontiac Grand Prix before being more widely
available.
 1989–1994: Nissan offered a head-up display in the Nissan 240SX.[1]
 1991: Toyota, for the Japanese market only, released a HUD system
for theToyota Crown Majesta.
 1998: The first color display appeared on the Chevrolet Corvette (C5).
 2003 : Cadillac introduced a HUD system for the Cadillac XLR.
 2012: Pioneer Corporation introduced a navigation system that
projects a HUD in place of the driver's visor that presents animations
of conditions ahead, a form of augmented reality (AR).[2][3]

8.  These displays are becoming increasingly available in production
cars, and usually offer speedometer, tachometer, and navigation
system displays.
 Night vision information is also displayed via HUD .
 General Motors ,Honda , Toyota ,Lexus ,Audi ,BMW
,Citroën, Nissan, Mazda and Kia currently offer some form of
HUD system.
 Add-on HUD systems also exist, projecting the display onto a
glass combiner mounted on the windshield.
 These systems have been marketed to police agencies for use
with in-vehicle computers

9. Head up display in helmet
 This helmet will use the visor for augmented reality and
will display anything from turn-by-turn navigation,
current speed to nearby points of interest.
 It’ll support 4G LTE connectivity, too as well as a
handful of sensors including G-sensor, gyroscope, digital
compass for head movement tracking.
