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.
