Several knowledge gaps as well as commonalities in the pertinent research literature were identified. Perhaps the overriding finding is that occupants' meaningful exposure to views of nature from within hospital circulation zones can potentially enhance wayfinding and spatial navigation. Future research priories on this subject are discussed.

The results showed that transparent waiting areas were significantly preferred. A significant positive relationship existed between the level of transparency and people's preference scores. The factor analysis indicated additional supportive features that may affect people's preferences, including daylight, perceived warmth, noninstitutional furniture arrangement, visual orientation, and the use of natural materials for interior design. However, these tentative results need to be furthered tested with the real patient population as the next step of this study.

Purpose: We propose a methodological framework to use immersive virtual environments (IVEs) in head-mounted displays for environmental design research. Background: IVEs offer researchers with experimental control and realistic representations of environments with high levels of ecological validity. IVEs are also increasingly being used to visualize proposed designs. Despite these tremendous benefits, IVEs are underutilized in environmental design research. We are unaware of preexisting frameworks that synthesize the methodological decisions related to the use of IVEs to conduct environmental design research. Methods/Results: We define the concepts necessary to conduct IVE research (virtual reality [VR], IVEs, ecological validity, visual realism, behavioral realism, and contextual realism). We also summarize the available study designs (correlational studies, experimental studies, and performance evaluations) and software systems used to create IVEs. We conclude with a conceptual framework that describes how research questions and study designs inform IVE selection and ecological validity. This framework is accompanied by a workflow that operationalizes the creation and use of IVEs in research. Conclusions: VR provides a robust and innovative research strategy for environmental design research because of its high degree of experimental control, rich data collection options, and opportunities for systematic evaluation of alternative design configurations.

Background: A positive distraction is a significant environmental feature that introduces positive feelings by diverting attention from stress or anxious thoughts. Existing research has deemed the application of positive distractions in pediatric environments to be significant. This study investigated the essential positive distractions and the associated health benefits. Aims: The aims of this study were to validate and extend evidence on positive distractions and play opportunities in the design of the public spaces in pediatric healthcare environments, translate existing evidence into design suggestions, and identify research gaps in this realm. Methods: A four-phased literature review method was employed in the study, including literature search, literature screening and selection, literature appraisal, and thematic analysis and in-depth discussion. Eventually, 27 peer-reviewed publications were reviewed and discussed in detail. Results/Conclusions: The gathered materials were grouped into six themes of positive distractions: (1) art and environmental aesthetics, (2) spatial arrangement and atrium, (3) considerations of socialization patterns, (4) play and interactive technologies, (5) sound and lighting interventions, and (6) access to nature. The research indicated that positive distractions in the pediatric healthcare environment provide a series of health benefits for patients, including improved behavioral and emotional well-being, reduced stress and anxiety, enhanced healthcare experience and satisfaction, and facilitated medical procedures and recovery. Yet significant research gaps emerged between positive distractions and play in garden spaces and spatial design to accommodate interactive technology and socialization in the public areas of pediatric healthcare environments. This study organized the understanding on the components of supportive environments and its outcomes for pediatric healthcare design.
