Smart Glasses for Older Adults with Cognitive Impairment: An Explanatory Mixed Methods Study (Preprint)

BACKGROUND Smart glasses might present a promising solution to support older adults with cognitive impairment in maintaining independence. However, there exists a critical gap in smart glasses research that incorporates recently developed models or directly engages older adults with cognitive impairment. OBJECTIVE This study aimed to use survey and interview techniques to explore the acceptability and usability of smart glasses among older adults with cognitive impairment. METHODS This explanatory mixed-methods descriptive study was conducted at an independent living senior apartment building among residents with memory complaint and/or cognitive impairment. This study consisted of a quantitative survey (n=26), followed by smart glasses beta testing with qualitative interview (n=14). RESULTS Overall, older participants with cognitive impairment conveyed a generally positive perception of smart glasses and their potential to support memory in daily life. Results suggest that participants prioritized the following smart glasses functions: audio reminders, phone calls, GPS, and distress signals, with audio reminders emerging as the highest ranked feature. Additionally, participants emphasized the value of an intuitive and quick interface and a preference for audio, rather than visual, information exchange. CONCLUSIONS This study supports the development and study of smart glasses for older adults with mild cognitive impairment. Smart glasses developers should place great importance on ease of use such as intuitive command interfaces, and equip the smart glasses with functions that are relevant to this population, especially audio reminders. Additionally, future work should examine the integration of smart glasses over a longer time and among a larger sample of older adults with cognitive impairment.
