Generating stereoscopic 3D (S3D) content is expensive, so industry producers sometimes attempt to save money by including brief sections of 2D content displayed with a uniform disparity, i.e. the 2D image is geometrically shifted behind the screen plane. This manipulation is believed to produce an illusion of depth which, while not as powerful as true S3D, is nevertheless more compelling than simple...
Displays with low pixel densities that were common in the 1980s and 1990s were shown to impair visual performance. Display technology, especially pixel density, has tremendously improved in recent years and new technologies allow densities of 264 ppi and beyond. Two experiments were conducted to test whether there are any measurable benefits of high pixel density displays (264 ppi) over moderate pixel...
The Optical Bonding (OB) technology has become a critical aspect of the performance of displays, and an essential requisite of their supply chain. This paper presents the development and the implementation of a technological solution to the OB of automotive instrument panel displays. The goal is to select and develop the adequate materials and bonding techniques that can meet the rigorous performance,...
Augmented reality (AR) has received increasing attention in minimally invasive surgery (MIS) applications. The goal of applying AR techniques to MIS is to enhance a surgeon's perception of the spatial relationship by overlaying invisible structures (e.g. tumor or vessels) onto the in vivo endoscopic video acquired during the surgery. One of primary issues of AR visualization is to provide correct...
Phosphate glasses with chemical compositions of 74.5NaH2PO4–20ZnO–5Li2O–0.5Sm2O3 and 74NaH2PO4–20ZnO–5Li2O–0.5Sm2O3–0.5Eu2O3 were synthetized by melt quenching method. We investigated the influence of Sm3+/Eu3+ doping on the optical properties of phosphate glasses. X-ray Diffraction indicates that the samples have an amorphous structure. DSC measurements show a good thermal stability of phosphate...
Gamut mapping is necessary to achieve color consistency between cross-media devices. In gamut mapping, accurate estimation of the gamut in each device is an important task because it directly influences on the quality of color consistency. However, depending on the samples or estimation method, a false gamut can be calculated, resulting in color distortion in the reproduced image. Accordingly, to...
Ce3+–Mn2+–Tb3+ cooperative barium–yttrium-orthosilicate phosphors composed of Ba9-3m/2-n-3p/2CemMnnTbpY2Si6O24 (m=0.005–0.4, n=0–0.5, p=0–0.5) were prepared using a solid-state reaction. The X-ray diffraction patterns of the resultant phosphors were examined to index the peak positions. The photoluminescence (PL) excitation and emission spectra of the Ce3+–Mn2+–Tb3+ activated phosphors were clearly...
We provoked cybersickness in participants by immersing them in one of two virtual roller coaster rides using a head-mounted display. As simulation technology is often used in training, our main intention was to examine the effect of the experience on their cognitive function. Participant reaction times before and after the experience were measured by averaging their response time to a visual stimulus...
