Many researchers study the built environment and the ways in which it can impact accessibility, engagement, and quality of life for different populations. However, not much of this research has focused on the experience of individuals with Mild Cognitive Impairment (MCI). MCI is a relatively new diagnosis and is characterized by difficulties in memory and reasoning beyond the expected effects of aging.

Through a collaborative project with Emory University, the SimTigrate Design Center is studying individuals with MCI, many of whom might go on to develop Alzheimer's disease and dementia. Many of these individuals are losing their ability to function independently at home and in the community; our goal is to develop ways to make everyday life easier and more joyful for individuals with this diagnosis.

Wayfinding Evaluation Tools

The ability to navigate and find one’s way through space is essential for independence and well-being in long-term care facilities, especially among older residents or those with dementia whose navigational skills may have been compromised by cognitive decline as well as environmental factors. Navigation in the case of assisted-living facilities does not only depend on the layout of the structure, but also on the type and quality of environmental factors, including signs, landmarks, and other visual cues. Three different methods of assessing wayfinding complexity before and after the intervention in terms of designing the physical environment were examined: space syntax analysis, Wayfinding Checklist, and the Tool to Assess Wayfinding Complexity. All three methods were used to evaluate wayfinding along the routes of varying complexity and revealed a variety of important characteristics of the environment that impact navigational skills, including its layout, decision-making process, and visibility.

Ongoing Empirical Study

The design of LTC facilities plays a critical role in supporting wayfinding, facilitating essential activities, and promoting residents’ independence. We are currently working on an empirical study that examines how spatial qualities of LTC facilities can predict residents’ wayfinding performance. Fifteen LTC facilities in the U.S. were selected, and the wayfinding performance of a total of 125 older adult residents was evaluated through predefined navigation tasks of three levels of complexity. The design typology was identified based on corridor structure (linear, branched, and courtyard). In addition to typical route characteristics (i.e., length, turns, floors visited), key spatial metrics of the floor plans were analyzed using Space Syntax methods. Stepwise regression models and the Kruskal-Wallis test were used to analyze the relationship between the spatial characteristics of the floor plans, typologies, and route features on wayfinding performance. Findings show that spatial layout impacts wayfinding performance, even when residents’ individual health and cognitive conditions are considered. The LTC facility typology has also played a role in residents’ wayfinding performance. The findings can inform the architectural design of LTC facilities, ultimately enhancing residents’ autonomy and quality of life. A manuscript is under development and will be coming soon.
