The rapid proliferation of speech-based intelligent personal assistants (sIPAs) presents transformative opportunities for enhancing older adults’ daily lives. This research seeks to address critical aspects of usability, learnability, user preferences, and adoption factors associated with sIPAs among older adults. The initial studies (1–3) investigated major usability and learnability issues, assessed the utility and effectiveness of sIPAs, and proposed design elements to improve user experience. These studies identified key challenges, such as complex interfaces and limited understanding of features, that hinder adoption.
Building upon these findings, two new studies are proposed. Study 4 focuses on developing and validating a tailored usability scale for older adults, ensuring accurate measurement of sIPA usability through robust psychometric properties. Study 5 explores how attitudes toward AI impact of UTAUT2 constructs on sIPAadoption behavior.
Together, these studies aim to bridge the gap between technological functionality and user experience optimization. The outcomes are expected to advance theoretical frameworks, inform sIPA design, and promote inclusive technology adoption among older adults, fostering empowerment and improved quality of life.
