Project Summary

A head-up display system projects an image directly onto the human retina with the help of a high-intensity imaging source. Head-up displays can give the illusion of viewing a typical screen-sized display hovering in the air several feet away. The backend technology of the project is augmented reality. Head-up displays are partially transparent displays that render information in a manner that allows the viewer to comprehend it while looking into the forward scene. It is known as a Head-up display because while using it in the operator’s head position is UP means forward instead of looking down. The technology of HUD is mainly used in the aviation industry, but now it has various applications in cars also. A head-up display is the outcome of software application and compass-based data about a vehicle position and the emergence of computer vision technology that can recognize objects on and around the road and the navigational information as transparent colored paths. HUDs are available in air crafts industries for a long time, and they are now finding their way into the automotive industry.

Project Objectives

In the future, every technology is going to shift to augmented reality. Everyone wants ease in the future. Humans now and in the future will totally be dependent on the technologies that give humans comfort.

The increase in the variety of connected features—along with safety features that offer superior convenience, comfort, and entertainment—available in passenger cars, drives the demand for connected vehicles. The increase in the time spent inside a car because of traffic congestion has increased the demand for in-car connected features. HUDs are an indispensable part of connected vehicles. Connected cars provide audio and visual entertainment from infotainment units and enhance the driving experience by providing convenience and safety features such as navigation, real-time traffic, and parking space updates.

Project Implementation Method

Our project is divided into four categories

• AR Software
• Imaging Source
• Optical Channel
• Simulated Environment

For making AR applications, several tools are used.

• Visual Studio
• Android Studio
• Unity
• VAPS XT

In our project, we are using VAPS XT. VAPS XT Offers HMI designers, systems engineers, and embedded engineers maximum control and flexibility for creating interactive real-time graphical displays. With an open architecture and integrated logic capabilities, VAPS XT provides the essential features for the design and deployment of certifiable cockpit displays. VAPS XT provides a model-based environment supporting all phases of development from initial concept to embedded deployment. Through a flexible porting structure, VAPS XT applications can be easily deployed to virtually any embedded target with excellent performance.

For Display, we are using Liquid Crystal Display. They work by using liquid crystals to produce an image. The liquid crystals are embedded into the display screen, and there's some form of backlight used to illuminate them. The actual liquid crystal display is made of several layers, including a polarizing filter and electrodes.

The liquid crystal display screen works on the principle of blocking light rather than emitting light. LCDs require a backlight as they do not emit light them. We always use devices that are made up of LCD displays that are replacing the use of cathode-ray tubes.

To display a bright and high-contrast image, an emphasis was placed on selecting the appropriate readily available optical components. This includes a proper transparent projection film and lenses for LCD focusing and image magnification. The complete optical design was then validated using custom-fabricated fixtures.

In order to produce a visibly large image on the windshield, a bi-concave lens was used as a magnification lens in the HUD’s optical assembly. This lens worked to effectively amplify the scanning angle as it traces the vector image on the display. To achieve the largest amplification possible, the selection criterion for this lens was based on a bi-concave lens with the shortest available focal length.

For the interconnection of software and simulation tools, we will use UDP interference.

Benefits of the Project

Low visibility is one of the major reasons leading to accidents in recent days. The problem of low visibility occurs mostly in the winter and rainy seasons. It can also happen in areas or countries affected by heavy icefall. The visibility of the road is very low; to overcome this problem HUDs can be used.

Driving at night is a difficult task for every driver because of limited information about the road, directions, and conditions.

Many times in actual driving conditions we get confused about where exactly to turn the car for reaching the destination we want. The HUD indicates the actual distance after which the car is to be turned. The map moves to show your progress along the route. If you move, rotate, tilt, or zoom the map, you can see your progress. When you approach an intersection or exit with multiple lanes, Navigation can help. Quickly see the estimated time remaining of your route on the bottom of your screen.

The turn-by-turn navigation features of modern HUDs are so good they’ve almost entirely replaced standalone GPS units. But in actual use, many drivers take their eyes off the road to check the map, which can be extremely unsafe. Even if you have a car mount to keep your phone in your field of vision, using it for navigation can still result in diverting your attention from the road, however briefly. The built-in navigation systems in many cars have the same problem. The distance and direction of the next turn, your current speed, and the road’s speed limit. It also shows whether you’re near any of the speed cameras in the company’s database and your estimated time of arrival.

The GPS Speed Heads Up Display projects your vehicle's speed up onto the windscreen, in your line of signs in bright, large, white numbers. These easy-to-read numbers allow you to see at a glance what speed you're traveling, without the need to look down at your dashboard. Project GPS speed onto the windscreen in the driver's line of sight, so you don’t have to take your eyes off the road to check your speed. Avoid speeding fines with audible over-speed alerts. The simple plug-and-play setup makes it quick and easy to begin using the device. Simply plug it into the cigarette lighter in your vehicle and as soon as the device has picked up satellite reception, you're good to go. Great for cars, vans, trucks, or vintage/custom vehicles that don't have a speedometer. Can also be calibrated to match your car's speedometer.

Technical Details of Final Deliverable

This review has covered a variety of ways in which a Head-up display can be used. The application of HUD in automobiles is very easy but costly. The current state of automotive HUDs suggests that we have fully characterized the benefits that might be achieved by displaying information with HUDs. The most important benefit that HUDs have demonstrated is that they keep drivers' attention directed toward the road. Because of HUD, the driver is able to give quicker reactions and fewer errors in detecting obstacles. This benefit could be applied to improving driver safety, and HUDs could be used to display information that would normally require a long glance time away from the road. HUDs can be used to display more complex sources of information that drivers normally access while driving such as navigation information, cellular phone status, or RPM of the engine. By displaying these sources of information at a head-up location, some of the long glance time away from the roadway that drivers would normally make could be eliminated. Future work should address how to display more complex information with HUDs and whether doing so will result in safety benefits to drivers The work will require an assessment of the effects of HUD complexity on environmental monitoring performance because locating complex HUDs close to roadway objects might cause drivers to be distracted from monitoring those roadway objects.
