Description
This paper presents an experiment designed to investigate if redundancy in an interface has any advantage over either words-based or symbols-based interfaces for older people during early or intermittent encounters with a device. Although older people used all three interfaces more slowly and less intuitively than younger ones, interestingly there were no age differences in terms of errors made on the words-based interface. In terms of differences between interfaces, older people (65+) completed tasks on the words-based interface faster and more intuitively than on the redundant (words and symbols) interface. Younger participants completed tasks faster on the redundant interface. Overall, this research suggests that a simple words-based interface is most effective for older users and that recommendations to use redundant interfaces for greater usability for older people may need to be re-visited.
Impact and interest:
Citation counts are sourced monthly from Scopus and Web of Science® citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads:
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
