Aging in place has been proposed in response to increasing aging worldwide. Recently, many community elderly care facilities (CECFs) in China have been built to meet the desire of the elderly to age in place and help them live better in familiar environments. This study instituted a correlation evaluation system between the elderly’s quality of life (QOL) and their satisfaction with CECFs. It assessed the QOL of the elderly in urban communities in Shenzhen and identified the issues of CECFs that led to the elderly’s low QOL. Firstly, a hypothesis of the relationship between QOL and CECF satisfaction was proposed on the basis of previous studies. The QOL–CECF model was verified and tested by structural equation modeling (SEM). It was found that the functional setting, planning layout, and operational management affect the QOL of the elderly. Secondly, this study investigated the issue of CECFs in three types of communities, namely, urbanized village communities, affordable housing communities, and commercial housing communities. A factor-based analysis revealed the intrinsic linkages between and extracted the composite factors of CECF indicators in the three types of communities, revealing the CECF issues that led to low QOL using a QOL–CECF satisfaction analysis. Lastly, this study proposed differentiated strategies for CECFs in urbanized village communities and affordable and commercial housing communities. This study can provide differentiated strategies for CECFs in various types of communities to effectively improve the QOL of the elderly and promote the sustainability of CECFs.

The general environmental factors that influence fixation distribution as part of pedestrian visual behaviour under natural conditions are unclear. Relative luminance and saliency are considered the parameters for predicting image-based fixation; however, they are not confirmed by evidence from the natural walking scenario. Field experiments using mobile eye-tracking glasses device were conducted on 16 participants in four commercial streets during day and night. Fixation data along with processed images extracted from eye-tracking glass video were analysed to investigate if relative luminance or saliency correlates with fixation distribution while walking. The results show that fixations within a 10° viewing angle were distributed in bright and more salient areas in the field of vision. Statistical analyses found a stronger positive correlation in saliency than in relative luminance and at night-time rather than under daylight. The correlation found between relative luminance/saliency and fixation distribution suggests that relative luminance/saliency may attract the visual attention of pedestrians. It will be beneficial for practical applications via a better visual environment, including lighting and guiding facilities for pedestrians, especially at night.

Most people today stay in a constant artificial lighting environment for a long time. Lack of sufficient daylight exposure may lead to circadian, sleep or mental problem. Dynamic lighting is an effective countermeasure in consideration of its dynamicity. However, besides its changeability, whether the daylight simultaneousness of dynamic lighting has a beneficial effect is unclear. A lab-based study was carried out to explore the effect of Daylight-Simulcasted Dynamic Lighting (DSDL), which simulates the simultaneous information of daylight conveyed by its variation. A reversed pattern of DSDL (Re-DSDL) was also introduced as one of the test conditions for comparison. The within-subject experiment was performed by 24 participants in four conditions: two dynamic lighting patterns (DSDL and Re-DSDL) in two periods (dawn and dusk). The dependent variables were psychological states, physiological indicators and cognitive performance. The results showed that DSDL brought greater benefit to the psychological state than Re-DSDL in general. During dawn, participants experienced less anger and depression in DSDL than in Re-DSDL; during dusk, participants experienced less anger and vigour in DSDL than in Re-DSDL. DSDL also had a significant effect on some of the physical indicators compared with Re-DSDL, but no effect on cognitive performance.
