In this work we present a complete methodology for robust authoring of AR virtual characters powered from a versatile character animation framework (Smartbody), using only mobile devices. We can author, fully augment with life-size, animated, geometrically accurately registered virtual characters into any open space in less than 1 minute with only modern(More)
When referring to augmented reality characters, their actual size comparing to their physical surroundings is an important factor responsible for creating more realistic and immersive environments. By creating life-sized augmented characters we are able to present them in real time with real characters and create applications where both real and digital(More)
In the last years, Geometric Algebra with its Euclidean, Homogeneous and Conformal models attracts the research interest in many areas of Computer Science and Engineering and particularly in Computer Graphics as it is shown that they can produce more efficient and smooth results than other algebras. In this paper, we present an all-inclusive algorithm for(More)
Over the last few years, recent advances in user interface and mobile computing, introduce the ability to create new experiences that enhance the way we acquire, interact and display information within the world that surrounds us with virtual characters [1], [2]. Virtual Reality (VR) is a 3D computer simulated environment that gives the user the experience(More)
