Abstract
This study contributes to effective risk communication for mobile devices by evaluating an intermediate-level display containing three major risk categories (personal privacy, device stability, and monetary loss). Participants performed an app-selection task, with risk scores for each category provided. Increased risk score in each category led to lower app-selection percentage, and this effect was influenced by self-reported risk concerns. The vertical and horizontal displays did not show differences in either task.
