OPTIMIZING USER EXPERIENCE OF OLDER ADULTS ON ONLINE RECIPE SHARING PLATFORMS

抄録

Older adults have a wealth of cooking knowledge but are absent from online food recipe sharing. The existing online food recipe sharing products mainly target young people and ignore the user experience of older adults. A solution to improve the usability of the conventional online food recipe sharing applications for older adults remains to be developed. Twenty participants aged 55 to 65 (Mean = 59.5) took part in the interview and subsequently joined a Within-subjects experiment in which the two experiments were spaced a month apart. The mutual features of conventional food recipe sharing products were compared with older adults' characteristics, contradictions between the two in describing a recipe manifested in conflicts of described frameworks and narrative ways. It was found that usability problems of multi-tasking, unnatural workflow, excessive restriction, and inaccessible interface are primary impediments that kept older adults from engaging in conventional food recipe sharing products. We verified that applying the tailored usability requirements is beneficial to improve the impression of older adults concerning user experience. The present study provides an alternative and specific perspective on research related to the usability of older adults. It would be conducive to engage older adults in online knowledge sharing and further drive the inheritance of traditional cooking culture.
