The Effects on Driving Behavior When Using a Head-mounted Display in a Dynamic Driving Simulator

Driving simulators are established tools used during automotive development and research. Most simulators use either monitors or projectors as their primary display system. However, the emergence of a new generation of head-mounted displays has triggered interest in using these as the primary display type. The general benefits and drawbacks of head-mounted displays are well researched, but their effect on driving behavior in a simulator has not been sufficiently quantified. This article presents a study of driving behavior differences between projector-based graphics and head-mounted display in a large dynamic driving simulator. This study has selected five specific driving maneuvers suspected of affecting driving behavior differently depending on the choice of display technology. Some of these maneuvers were chosen to reveal changes in lateral and longitudinal driving behavior. Others were picked for their ability to highlight the benefits and drawbacks of head-mounted displays in a driving context. The results show minor changes in lateral and longitudinal driver behavior changes when comparing projectors and a head-mounted display. The most noticeable difference in favor of projectors was seen when the display resolution is critical to the driving task. The choice of display type did not affect simulator sickness nor the realism rated by the subjects.

EVALUASI EYE TRACKING TERHADAP PERSEPSI WARNA DAN GAMBAR PADA PRIMARY DISPLAY PANEL KEMASAN

Home industry food packaging displayed on shelves in stores will compete with products from other brands that areplaced close together. In order to attract consumers’ attention and assist them in the purchasing decision-making process, packaging that has a competitive advantage is needed. This research is limited to the Primary Display Panel (PDP) packaging of home industry banana chips. In previous studies, the research used was quantitative, but this does not reveal the whole story. The data recording process can support “what” the participant looks at but does not reveal “why” they look at it. For this reason, this research is aimed to establish a broader understanding of what participants perceive of the packaging design seen using eye tracking methods and why it happened. This study uses qualitative approach. Thestudy consists of three phases: literature study, eye tracking data recording, and data processing and interviews analyzedusing content analysis. The result is colors and images are perceived to be the same by teenagers and young adults. There is no connection between likes and dislikes for colors/images with colors preference in choosing snack products. The results can be used by producers and packaging designers to create packages that generate consumer purchase interest.

Beyond colour gamuts: Novel metrics for the reproduction of photoreceptor signals

Colour gamuts describe the chromaticity reproduction capabilities of a display, i.e. its ability to reproduce the relative cone excitations from real-world radiance spectra. While the cones dominate “canonical” visual function (i.e. perception of colour, space, and motion) under photopic light levels, they are not the only photoreceptors in the human retina. Rods and melanopsin-containing intrinsically photosensitive retinal ganglion cells (ipRGCs) also respond to light and contribute to both visual and non-visual light responses, including circadian rhythms, sleep-wake control, mood, pupil size, and alertness. Three-primary display technologies, with their focus on reproducing colour, are not designed to reproduce the rod and melanopsin excitations. Moreover, conventional display metrics used to characterize three-primary displays fail to describe the display’s ability (or inability) to reproduce rod and melanopsin excitations, and thus do not capture the display’s ability to reproduce the full human physiological response to light. In this paper, three novel physiologically relevant metrics are proposed for quantifying the reproduction and distortion of the photoreceptor signals by visual displays. A novel equal-luminance photoreceptor excitation diagram is proposed, extending the well-known MacLeod-Boynton chromaticity diagram, to allow visualizations of the five-dimensional photoreceptor signal space in a three-dimensional projection.

VISUAL PERCEPTION OF PRIMARY DISPLAY PANEL OF COFFEE PACKAGING

Previous research only discussed the perception of color combinations for the primary display panel. This study is not only focused on color; but also on other visual elements. This research aims to know the primary display panel that is more desirable to consumers and uncover the linkage between product perception and preference by using quantitative approach. As for the method used is the case study of brand Puntang Coffee. Data collection was done by conducting literature study, redesign experiment and questionnaires, whereas data analyze by using the ANOVA test. From data, it was revealed that the highest valuation of respondents of all three designs displayed is design C; which proposed by the designer team, that are perceived better by respondents.

Analysis of Novel OLED Based Four-Primary Displays

Novel four-primary displays utilizing organic light-emitting devices (OLEDs) was analyzed theoretically and experimentally. Using the fitting curves of the OLEDs electroluminescent (EL) characteristics, RGBW four-primary display is clearly shown to be more energy efficient than traditional RGB three-primary display, especially as the efficiency of the OLEDs is getting higher.
