%A Rabbi, Ihsan %A Ullah, Sehat %D 2016 %T A Survey on Augmented Reality Challenges and Tracking %K %X 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. %U https://actagraphica.hr/index.php/actagraphica/article/view/44 %J Acta Graphica %0 Journal Article %P 29-46 %V 24 %N 1-2 %@ 1848-3828 %8 2016-12-21
