“…The results show that the modified interface increases cognitive efficiency, which is consistent with the findings in the literature (i.e., left placement increases cognitive efficiency), 32 but because Task I does not require involve changes in position and color, follow‐up studies should also expand the experimental parameters to include position and color and discuss their influence on cognitive load. The results of Task II show that a larger font is cognitively less demanding, which is consistent with the findings in Dobres et al 36 In future work, more detailed differentiation of the font size should be done to explore the effects of different font sizes on cognitive load.…”

Optimizing a display interface design for rollers is the focus of this study, in which the effects of cognitive load of the operator are taken into consideration, which greatly contribute to acquiring interface information accurately and enhancing cognitive efficiency. To reduce the cognitive demand of the operator, a commonly used generic display interface is modified in this study. Three methods are used to measure the cognitive load, including subjective (NASA Task Load Index) and physiological (eye movement) measurements and through task performance. These three measurements are used with two groups of subjects: those who view the original and those who are given the modified version during four given tasks. The findings show that the modified interface has a significant impact on eye movement and completion time of the four tasks. After a comprehensive analysis of the results from the three types of measurement, it is found that the modified interface is less cognitively demanding than the original interface and allows a higher cognitive performance, which accordingly demonstrates that the modifications made are effective in reducing cognitive load. This study therefore provides the scientific basis for advancing interface designs and evaluating the display interface designs for engineering equipment.

“…Furthermore, many older women face concurrent issues, like visual impairment, hearing di culties, or dual sensory loss [69,70]. The majority of existing technology-based health solutions fail to address these challenges given that they are primarily delivered or hosted on websites and mobile applications [71][72][73].…”

Background One of the most vulnerable populations to COVID-19 is women. Multiple factors associated with violence against women (i.e. sexual assault, domestic violence, homelessness) create an increased vulnerability for women during the COVID pandemic. Women also constitute the majority of older nursing home residents and healthcare workers (e.g., nurses), who have the most pronounced exposure to COVID-19. These factors combined with resource restraints like rationing and lack of access to healthcare can further exacerbate women’s physical and psychological health issues. While literature has well-documented challenges that women face during COVID-19, there is a lack of evidence-based solutions that have the potential to mitigate these difficulties. Therefore, to address this issue, we aim to conduct a systematic review of the literature to: (1) identify interventions designed for women in the context of pandemics, (2) describe the characteristics and effects of these interventions concerning the distinctive traits of women and pandemics, and (3) present evidence-based health solutions for women to mitigate challenges they face amid and beyond COVID-19. Methods A systematic review of literature will be conducted on databases including PubMed, PsycINFO on the EBSCO platform, CINAHL on the EBSCO platform, and Scopus, based on a search strategy developed in consultation with an experienced medical librarian. Titles, abstracts, and full-text articles will be screened against eligibility criteria developed a priori. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses procedures will be adopted as the reporting framework, and data extracted (e.g., intervention details) will be evaluated by a multidisciplinary research team. Results NA for now—This is a protocol study. Conclusions Findings of this study will fill an important void in the literature. Considering that, in times of pandemic, women are especially subject to grim health disparities, like pronounced exposure to COVID-19, reproductive health issues, elevated domestic violence, increased mental health challenges, and lack of access to healthcare services, the need for evidence-based health solutions that could address these unique challenges is of paramount importance. A comprehensive understanding of the characteristics and effects of health solutions available to women in the context of pandemics can also help researchers identify areas of improvement regarding intervention design and development. This may further safeguard women’s health and wellbeing amid pandemics like COVID-19 and beyond. Study Protocol Registration: PROSPERO CRD42020194003

“…Screen density and pixel arrangement are large factors for text readability, but many font attributes also have a strong impact. These font attributes can include the typeface, weight, contrast, and color . These problems are well understood in conventional text rendering on a 2D display, in which the text is aligned to the pixels.…”

Aligning content rendering resolution and feature size with display capability in near‐eye display systems

In order to create a satisfying experience with near‐eye displays, the content must be adapted to be legible on the display used. New displays are using subpixel arrangements that can limit the minimum resolvable feature size to something greater than with the conventional RGB stripe arrangement. We conducted an experiment to measure the minimum and preferred size of text in two virtual reality (VR) displays systems and find that the text size is display limited. We then measure several displays with different pixel arrangements to determine whether the subpixel arrangement could impact legibility. We propose several Fourier metrics that can be computed from the measured data to categorize the capability of the display and describe a framework for selecting the appropriate content from a set of discrete tiers.
