Biography

Llogari Casas is a computer scientist and entrepreneur in the field of Augmented Reality (AR). He holds a degree in Multimedia from Universitat Politècnica de Catalunya and a master's degree in Computer Animation from Kingston University London. He obtained his Ph.D. from Edinburgh Napier University as part of a Horizon 2020 Marie Curie Fellowship, a highly regarded research fellowship established by the European Commission.

One of Casas' notable achievements is the development of Intermediated Reality, a groundbreaking tool that brings real-world objects to life using Augmented Reality. This tool enables objects such as statues in museums, characters and consumer products to interact with users through mobile devices. Unlike traditional Augmented Reality, which overlays virtual objects onto reality, Casas' innovation focuses on animating real objects and creating believable animations. The animations even include the deformation of an object's shadow as it moves. In recognition of his achievements, Casas was awarded the Young Computer Researcher award by the Spanish Scientific Society of Informatics in 2021.
