Abstract

With the transition to fully autonomous vehicles, non-driving related tasks (NDRTs) become increasingly important. In-car AR gives passengers the possibility to engage with their surroundings via world-fixed POIs. We conducted a field study (N=38) examining six visualization parameters: positioning, scaling, rotation, render distance, information density, and appearance. Our findings reveal user preferences and general acceptance of AR functionality, and we derived UX guidelines for POI visualization in in-car AR.
