Introduction Heads-up Displays (HUDs) initially developed for

aviation are now widely distributed and incorporated in media as well as computing technology.

Google Glasses, a novel product expected to release this year, is projected to push the boundaries of this technology.

It will combine the use of HUD with eye tracking technology in the form of user controllable glasses.

Overview Heads-up displays allow users to receive data

on a screen in front of them. Each HUD has three parts

The combiner, which is the surface the data is projected on

The projector unit, which puts out the imageA video generation computer, which creates the

images. 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.

An optic collimator can be used to replicate a target at any given distance without an apparent overlap. (See Figure 1)

the background rather on top of it. [1]

• The combiner is coated with a transparent film that allows all other light to pass through.

• It reflects or refracts the light generated by the projector unit, making it appear to float on the screen.

History The HUD we know today evolved from the

reflector sight on German planes in 1937. They allowed targeting assistance to be added

to a scope and displayed information such as air speed velocity and attack angle.

sight in 1937 [2]

The Buccaneer The Blackburn

Buccaneer developed for the British Royal Navy and Royal Air Force was the first plane with a built-in heads-up display.

• Was prototyped in 1958, but flew for the British from 1968 until 1994.

HUDs in Cars

The first heads-up display was added to the Oldsmobile Cutlass Supreme in 1988.

There were also some included on Toyotas in 1991.

• Currently, heads-up displays are offered by many different car manufacturers, and as third-party add-ons.

Design Specifications Field of View: indicates the angle(s),

vertically as well as horizontally, subtended at the observer’s eye, in which the combiner displays symbols in relation to the outside view.

Collimation: The projected image is collimated which makes the light rays parallel. This means that the observer's eyes do not need to refocus to view the outside world and the HUD display.

Eyebox: Visible area of HUDModern HUD eyeboxes are usually about 5 lateral by

3 vertical by 6 longitudinal inches.

Luminance/contrast — Displays have adjustments in luminance and contrast to account for ambient lighting.

Scaling - The displayed image are scaled to present to the observer a picture that overlays the outside world in an exact 1:1 relationship.

Applications Heads-up displays are

appearing on more consumer technology including: ski goggles tools for runners more complicated

automobile peripherals MicroVision is currently working with Pioneer to

create a large heads-up display that can work with your smartphone to add in directions.

Virtual Retina Display Shoots a beam of

light directly on the retina to display an image in front of the wearer’s eye.

Development since 1991

• It will allow for the development of head-mounted displays, which serve as a HUD for the human eye.

Gaming Industry Players use HUDs

to keep track of their health, ammunition or objective.

• A technique that evolved especially as first-person perspective games, like shooters and RPGs, became mainstream.

• They've also appeared in sci-fi movies as part of everyday technology.

Aims to create augmented reality glasses

At the simplest this means receiving text messages emails real-time directions
