In the past, augmented reality (AR) research focused mostly
on visual augmentation, which requires a visual rendering
device like head-mounted displays that are usually obtrusive,
expensive, and socially unaccepted. In contrast, wearable
audio headsets are already popularized and the auditory
sense also plays an important role in everyday interactions
with the environment. In this PhD project, we explore audio
augmented reality (AAR) that augments objects with 3D
sounds, which are spatialized virtually but are perceived
as originating from real locations in the space. We intend
to design, implement, and evaluate such AAR systems that
enhance people’s intuitive and immersive interactions with objects in various consumer and industrial scenarios. By
exploring AAR using pervasive and wearable devices, we
hope to contribute to the vision of ubiquitous AR.
