Evaluating the cross-platform usability of multiple interactive systems has become increasingly essential. Despite eye tracking being used to supplement traditional usability assessment, there is little research on its use for cross-platform usability evaluation. Our exploratory study seeks relationship between eye-tracking metrics and cross-platform usability problems. We user-tested three cross-platform services and identified a set of usability problems. We separated the identified problems into traditional and cross-platform usability problems. Some of the cross-platform usability problems were associated with users’ eye-tracking patterns. We found that consistency on many levels is a major problem cross-platform and we recommend some considerations for evaluators to use as indicators to predict possible cross-platform usability problems.
