Models of guidance in augmented reality

Sammanfattning: Augmented Reality (AR) is a new and exciting technology with wide potential implementation areas, from medical to industry. One of the fields from which AR is gaining attention is the manned security industry. Unfortunately, this is also one of the areas in which formal studies on AR is lacking. Ais study aims to bridge the gap in knowledge by evaluating an AR-application designed for the Microsoft HoloLens to support working security guards with navigation and a list of current tasks without negatively affecting their situation awareness. Ae study is based on a pilot project in which the application was designed. Results from the pilot project suggested that participants’ situation awareness was enhanced when using a round model of guidance in AR-navigation compared to when using an arrow, even though a majority of participants subjectively preferred the arrows. In the current study, a third model of guidance was added, and potential confounding variables were controlled for. A majority of participants still preferred the arrows, however, results suggests no significant difference in participants’ situation awareness between the three models of guidance. Ae study did not replicate results from the pilot project, this might be due to limitations pertaining to the AR-technology used in the study.
