KETI Develops AR HUD Technology Using Holographic Technology
Implementing a driver-centered HUD by reducing field of view distortion while driving


On the 8th, the Korea Electronics Technology Institute (KETI) developed augmented reality (AR) HUD technology that enhances the realism of vehicle HUD (Head Up Display) technology using hologram technology.

Existing vehicle HUDs display graphic images through the windshield or a separate screen, which provides excellent driving stability but has limitations in expressing realistic information for next-generation in-vehicle infotainment (IVI) services.

AR HUD technology using holographic technology can display image information on the road or surrounding terrain through the vehicle's windshield using HOE film, thereby implementing a highly realistic wide-angle HUD image.

The technology developed by KETI is an AR HUD technology that implements holographic technology by utilizing HOE attached to the front transparent windshield of a car, which can reduce distortion of the field of vision while driving and implement driver-centered HUD services.

10,000 knits Through the development of the above HUD laser printer, the HUD image is clear even in bright places, and the distance at which the reflected image is formed is created visually 6m ahead of the HOE film, thereby increasing the consistency with the driver's forward gaze and enhancing driving safety.

Hong Ji-soo, a senior researcher at KETI's Hologram Research Center who led the development, said, "Although the development of the fusion technology of holograms and AR is somewhat delayed, we have secured our own technological prowess to the point where it can be installed in vehicles if we improve the commercialization of this technology a little." He added, "With future expanded research, we will be able to expand the fields of application to include defense, aerospace, and other fields."

Meanwhile, this technology was developed as part of the 'Development of Convergence New Service Technology Based on Large-Screen Expandable AR HUD for Vehicles' project supported by the Ministry of Science and ICT, and was jointly conducted by KETI, Future Technology Research Institute, Epic Optics, and Hololab.
