Abstract

There has been a steady growth in the global population of elderly people, challenging researchers in the HCI community to design technologies to help them remain independent and preserve their quality of life. One approach has been to create assistive technology solutions using Personal Digital Assistants (PDAs). However, some have questioned whether older people can use PDAs because of age related problems with dexterity, coordination, and vision. This paper presents an initial usability study that shows there are no major differences in performance between older and younger users when physically interacting with PDAs and completing conventional (e.g. pressing buttons, viewing icons, recording messages) and non-conventional tasks (e.g. scanning bar codes).
