Mobile search: how to present search results for older users

With thirty-one older participants, this study is conducted to investigate how to present search results on mobile device with aim to improve older users´ mobile search performance and satisfaction, and to alleviate perceived disorientation and task workload. The focus groups section is to consider the issue of how many total number of search results should be provided for small- screen search. And then with a 2 (with or without presentation of search results) times 3 (how many results should be displayed when total search results determined) factor experiment is designed to look at the users´ mobile search behavior. Based on the results, some guidelines were excluded for those involved in designing approaches that are more appropriate for older users´ using small screen contexts.
