Harnessing the Visual Salience Effect With Augmented Reality to Enhance Relevant Information and to Impair Distracting Information

This study investigated several visualizations, including enhancing relevant information and impairing distracting information, that harnessed the visual salience effect with augmented reality (AR) to assist people in searching for targets. The experiment used a scenario of shopping for food products where participants searched for the target product wearing an AR head-mounted display that presented the visualizations. In addition, the field-dependent (FD) and field-independent (FI) cognitive styles of users were investigated. First, FI participants completed the product selection tasks more quickly than FD participants when using the visualizations of enhancing relevant information but not the visualizations of impairing distracting information. Second, the visualizations of impairing irrelevant information improved the search speed but not the accuracy of FD participants compared to the visualizations of enhancing relevant information. Third, participants perceived a higher clarity of the highlighted items when they were highlighted with a frame rather than an overlay.
