“…HE vehicle head-up display (HUD) system can display driving information such as vehicle speed, fuel consumption, warning signals and navigation arrows to the driver through the windshield or combiner [1]- [4]. With HUD, the driver always looks straight ahead on the road without frequently moving the sight to see the dashboard, thus improving driving safety [5].…”

The traditional head-up display (HUD) system has the disadvantages of a small area and a single display plane, here we propose and design an augmented reality (AR) HUD system with multi-plane, large area, high diffraction efficiency and a single picture generation unit (PGU) based on holographic optical elements (HOEs). Since volume HOEs have excellent angle selectivity and wavelength selectivity, HOEs of different wavelengths can be designed to display images in different planes. Experimental and simulated results verify the feasibility of this method. Experimental results show that the diffraction efficiencies of the red, green and blue HOEs are 75.2%, 73.1% and 67.5%. And the size of HOEs is 20cm×15cm. Moreover, the three HOEs of red, green and blue display images at different depths of 150cm, 500cm and 1000cm, respectively. In addition, the field of view (FOV) and eye-box (EB) of the system are 12°×10°a nd 9.5cm×11.2cm. Furthermore, the light transmittance of the system has reached 60%. It is believed that this technique can be applied to the augmented reality navigation display of vehicles and aviation.

“…Therefore, we have developed a monocular HUD and accurate depth perception control method for navigation and pointing at obstacles. We called the method the dynamic perspective method [7], [8]. The monocular HUD does not have the drawback of the binocular parallax because optical systems of the monocular HUD enable a user to observe images with only one eye, as shown in Fig.…”

SUMMARYA novel depth perception control method for a monocular head-up display (HUD) in a car has been developed, which is called the dynamic perspective method. The method changes a size and a position of the HUD image such as arrow for depth perception and achieves a depth perception position of 120 [m] within an error of 30% in a simulation. However, it is difficult to achieve an accurate depth perception in the real world because of car vibration. To solve this problem, we focus on a property, namely, that people complement hidden images by previous continuously observed images. We hide the image on the HUD when the car is vibrated very much. We aim to point at the accurate depth position by using see-through HUD images while having users complement the hidden image positions based on the continuous images before car vibration. We developed a car that detects big vibration by an acceleration sensor and is equipped with our monocular HUD. Our new method pointed at the depth position more accurately than the previous method, which was confirmed by t-test.

“…The foreground object looks bigger and the background object looks smaller. We investigated whether these parameters were effective both under the indoor simulator condition and the outdoor real space condition with the static perspective condition [6]. On the other hand, dynamic cues exist for the monocular depth cues.…”
