A Comparison of Health Visualization Evaluation Techniques with Older Adults

Aging-associated changes in visual acuity, cognition, and motor control in addition to attitudinal and affective perceptions of technology impact the design of information systems for older adults. Although design guidelines and cognitive theories on information visualization exist, they are often understudied for use with older adults. In an effort to evaluate interactive health visualizations with older adults, the authors applied and compared a benchmark evaluation, an insight-based evaluation, and a subjective usability questionnaire. They were unable to identify statistically significant differences between visualizations using the benchmark evaluation, but found moderate differences with the perceived usability scale and more granular differences through the insight evaluation.
