Older adults’ navigation performance when using small-screen devices:does tutor help?

摘要

Nowadays ICT-technologies saturate the market and nearly everybody encounters them to a greater or lesser extent. This especially applies to mobile devices, which are increasingly used by diverse groups of end users. However, a bunch of mobile technical devices does not cater to older users and their demands. This paper reports the findings of a study that examined performance of older and younger adults using personal data management applications on a PDA in terms of effectiveness, efficiency, and acceptance.
