A Survey on Augmented Reality Challenges and Tracking

Abstract

This survey paper presents a classification of different challenges and tracking techniques
in the field of augmented reality. The challenges in augmented reality are
categorized into performance challenges, alignment challenges, interaction challenges,
mobility/portability challenges and visualization challenges. Augmented
reality tracking techniques are mainly divided into sensor-based tracking, visionbased
tracking and hybrid tracking. The sensor-based tracking is further divided
into optical tracking, magnetic tracking, acoustic tracking, inertial tracking or any
combination of these to form hybrid sensors tracking. Similarly, the vision-based
tracking is divided into marker-based tracking and markerless tracking. Each
tracking technique has its advantages and limitations. Hybrid tracking provides a
robust and accurate tracking but it involves financial and tehnical difficulties.
