Usability testing by older adults of a computer-mediated health communication program.
Failure to adhere to an antihypertensive regimen and interactions between antihypertensives and other medicines represent serious health threats to older adults. This study tested the usability of a touch-screen-enabled personal education program (PEP). Findings showed that older adults rated the PEP system usability, system usefulness, and system-use satisfaction at a moderately high level for prototype-1 and at an exceptionally high level for prototype-2. A 201.91% reduction in interface errors and a 31.08% decrease in interface time also were found between the two trials. This participatory usability design was highly successful in tailoring its program interface design to accommodate older users to enhance their health communication and technology use efficacy.
