Accessibility Research on Multimodal Interaction for the Elderly

This study examines the potential and effectiveness of multimodal interaction techniques to enhance the accessibility of digital products for older adults. By integrating information from multiple sensory channels such as visual, auditory, and tactile, multimodal interaction aims to reduce older adults’ reliance on a single sense and provide a more intuitive and flexible interaction experience. The research methodology includes a literature review and an empirical study that evaluates the effectiveness of the technology in actually improving the use of smart devices by older adults. The results show that multimodal interaction significantly improves usage efficiency and reduces error rates. The study proposes optimization principles for multimodal interaction interfaces designed for the elderly, and it is expected that through in-depth research and application, the design of digital products will be more inclusive, meet the special needs of the elderly, and promote their social participation.
