Age-friendly design framework for information animations: a mixed-method research validation

With the rapid aging of the global population, challenges in dynamic visual information processing among older adults have gained increasing attention. Drawing on cognitive aging theory and multimedia cognitive load theory, this study investigated a strategic framework for age-friendly animated information, highlighting the multidimensional nature of dynamic visual cognition in older adults. Using a mixed-methods approach-including literature reviews, interviews, case analyses, and questionnaire surveys-the study examined the effects of perceptual experience (PE), information complexity (IC), and degree of audiovisual integration (AVID) on perceived ease of use (PEOU). The results revealed that PE and AVID significantly and positively influenced PEOU, whereas IC had a significant negative effect. Furthermore, the interaction of multiple independent variables introduces potential interference and complex relationships. Based on these findings, the study proposes a strategic framework for age-friendly animated information, emphasizing the reduction of IC, enhancement of PE, and optimization of AVID to improve information reception among older adults. This framework offers both theoretical guidance and practical support for the development of age-friendly dynamic visual media.
