Abstract

Of many relevant issues related to HCI (Human Computer Interaction) and senior adults, the focus of this study was on the evaluation of link configurations in information websites. The main objectives were: (1) The fitness of various link configurations on the navigation efficiency of seniors (vs. younger users) (2) Recommendation of the best link configurations to use and those to avoid in suited for the elderly (and the young).

24 experienced Internet users divided by age into two groups (N=12): seniors (age: 65-85) and young (age: 25-34) participated in the experiment.

The participants were asked to navigate through four experimental tourism websites with integrated hidden tracking programs and to find answers to specific search tasks. Nine different common links prototypes (button links, text links, icons & list box with GO button) were installed in the experimental websites.

The experimental parameters were: time, number of errors, number of steps, and satisfaction. A comparison between the two age groups and within each group was performed for each parameter.

The results indicated that seniors are capable of finding information as well as younger users but at a slower pace. The variability of data among senior users was found greater than among the younger users. It is recommended to use “image” icons (with static text) or horizontal “text” links. “Image” icon (with static text) was the preferred link configuration of most of the senior and younger participants. Links to be avoided are the “button” and the “list box” with GO button links.
