78‐4: Screen Door Effect Mitigation and Its Quantitative Evaluation in VR Display

Abstract

The screen door effect (SDE) is the great challenge in the development of VR display, which obstructs immersion in the virtual reality. In this paper, we propose the quantitative investigation method for SDE, and demonstrate how the SDE can be systematically mitigated without degrading image quality. Author KeywordsVirtual Reality; Screen Door Effect; OLED; Low-pass filter Objective and BackgroundVirtual Reality (VR) devices have attracted huge interest from industries in anticipation of numerous applications for entertainment, education, medical uses and so on [1]. As VR hardware becomes more affordable, it has come into wide use. By wearing a VR headset, we are immediately surrounded by realistic scenery projected by head-mounted display. Many technologies are required for making the immersive experience in VR headsets; however, display technology is critical because it is directly related to our vision. Figure 2. Microscopic images (X50) is shown (a) without and (b) with the SDE reduction film.

“…Two further participants were excluded from the analysis as they experienced the screen door effect (SDE), a visual artifact letting the viewer see distinct pixels or lines. The SDE limits immersion, as it reduces visual quality (Cho et al, 2017). Thus, a sample size of n = 19 remained per group (3D/360°group: Mage = 21.26, SDage = 2.54, 15 female, 17 right-handed; 2D group: Mage = 23.26, SDage = 2.60, 15 female, 14 right-handed).…”

Do I Smell Coffee? The Tale of a 360° Mulsemedia Experience

“…The decrease in user-perceived quality between the 2.5K and 4K video encoding rates as illustrated in Figure 4 highlights the fact that the use of 4K resolution in 360º mulsemedia might be excessive considering our setup, and therefore, this can be explored as proposed in the second interpretation. Whilst this might have been influenced by hardware limitations of the HMD device, such as the field of view and screen-door effect 18 , it nonetheless reinforces (but in the mulsemedia arena) issues with which the community has been aware of.…”

Recognition of Customers’ Impulsivity from Behavioral Patterns in Virtual Reality

“…In those methods, the person may be unable or unwilling to respond correctly. Besides, there are some technological limitations of the current performance of HMDs, such as vergence-accommodation conflict, which happens when the brain identifies a discrepancy between the distance of a virtual 3D object and the focusing distance needed for the eye to perceive the object [75], and the screen-door effect, which consists of observing the mesh between pixels in the near digital screens [76].…”
