PROTOTYPING THE “MEMO” MOBILE APPLICATION USING INTERFACE HEURISTICS FOR OLDER ADULTS

ABSTRACT Objective: to build a mobile app prototype for the Canadian cognitive training program Méthode d’Entrainement pour une Mémoire Optimale, with an interface and design specifically for older adults. Method: a methodological study of technological production incorporating interface heuristics for small touchscreens for older adults, combined with the Prototyping Paradigm, systematized into: (1) communication; (2) rapid design and modeling; (3) prototype construction; and (4) deployment, delivery, and feedback. The prototyping process took place between February 2022 and August 2023. Results: the prototype included 216 screens divided into six sections, each containing cognitive training activities and information on aging and cognition. A concept map was created covering all content, followed by wireframing of the screens, enabling application of interface heuristics, including cognitive, visual, data entry, touch, and generational aspects. Conclusion: the adopted approach, combined with interface heuristics for the older adult population, resulted in creating a unique prototype whose aspects were meticulously planned and refined to ensure a fluid and seamless user experience, helping to reduce the accessibility gap of technological resources for these individuals.
