Abstract
Wearable devices like smart glasses and head-mounted displays are be-coming popular. Information display systems can show information requiring immediate viewing by users daily. When these systems are applied to health care services, users can receive suggestions on appropriate healthy behaviors to take at a given time. When displaying information, the annoyance that users feel should be a low, and the certainty that the information is viewed should be high; however, both are in a trade-off relationship. Thus, we propose a display method that reduces annoyance and increases the certainty that information will be viewed. We focus on the actions users perform to view information and hypothesize that actions prompted by some form of stimulation can decrease the annoyance felt in viewing information. Thus, we propose an information display method that uses visual attention guidance, in which the area of a small circle changes in brightness within the user’s peripheral vision. In an experiment with 10 participants, the method demonstrated reduced annoyance and increased certainty, indicating that it is effective and that prompting users to focus on information with this method can decrease annoyance and increase the certainty that information will be immediately focused on.
