LaViola has made contributions to the development and usability of virtual and augmented reality technologies. By comparing unscented and extended Kalman filtering in enhancing human head and hand tracking for virtual reality applications, he found that extended Kalman filtering is preferable due to its lower computational overhead and better ...
For his PhD course, Billinghurst created the Magic Book, a children's book animated through augmented reality produced by a head-mounted display. [ 2 ] [ 5 ] Billinghurst describes the Magic Book as technology "that allows you to overlay computer graphics onto the real world, in real time".
Augmented reality (AR) is a type of virtual reality technology that blends what the user sees in their real surroundings with digital content generated by computer software. The additional software-generated images with the virtual scene typically enhance how the real surroundings look in some way.
Virtual reality (VR) is a computer application which allows users to experience immersive, three dimensional visual and audio simulations.According to Pinho (2004), virtual reality is characterized by immersion in the 3D world, interaction with virtual objects, and involvement in exploring the virtual environment.

Augmented learning is an on-demand learning technique where the environment adapts to the learner. By providing remediation on-demand, learners can gain greater understanding of a topic while stimulating discovery and learning. [1]

Mediated reality continuum showing four points: augmented reality, augmented virtuality, mediated reality, and mediated virtuality on the virtuality and mediality axes. This continuum has been extended into a two-dimensional plane of virtuality and mediality. [2] Taxonomy of reality, virtuality, mediality. The origin R denotes unmodified reality.
Extended reality (XR) is an umbrella term to refer to augmented reality (AR), mixed reality (MR), and virtual reality (VR). The technology is intended to combine or mirror the physical world with a "digital twin world" able to interact with it, [1] [2] giving users an immersive experience by being in a virtual or augmented environment.
