Abstract

Eye-tracking is a valuable tool for usability research. Studies into the effect of age on eye-movement behavior tend to indicate a propensity for slower viewing and longer times spent examining information. This pattern is usually attributed to the general physiological and cognitive slow-down associated with normal aging. In this paper, however, across three different tasks based on computer and internet use (free-viewing, visual search, and browser interaction), we show that among older adults (n=18, age range: 70-93) computer experience appears to be a highly important factor in eye-movement behavior. We argue that as a consequence of the experimental environment used in modern eye-tracking studies, characteristics such as familiarity and experience with computers should be taken into account before conclusions are drawn about the raw effects of age.
