Toward an immersion platform for the world wide web using autostereoscopic displays and tracking devices

Abstract

Figure 1: Autostereoscopic technology allows 3D images popping out of the screen while natural interaction provides a seamless manipulation of 3D contents. AbstractA few years ago, the introduction of the WebGL API has allowed displaying 3D content in web browsers very efficiently by using the power of 3D accelerators. Nowadays, 3D web applications, from games to medical imaging, tend to compete with their desktop counterparts. Among the main factors that can improve the feeling of presence in terms of impressiveness, immersion and natural interaction play a prominent role in enhancing the quality of the user experience. Both immersion and natural interaction rely on dedicated hardware like 3D displays and tracking devices. Unfortunately, browser makers do not supply JavaScript mechanisms for accessing hardware for security reasons. In this paper, we propose a plugin-free solution using the new features of HTML5 (WebGL and WebSockets) in order to handle autostereoscopic displays and widespread tracking devices like IR depth sensors for providing immersion and natural interaction within the web browser.

Abdominal morphometric data acquisition using depth sensors

“…The perspectives of this work are multiple. In order to provide medical practitioners the ability to make a diagnosis, we started to combine this tool with the web framework that we developed [21]. It already supports RGB-D cameras and can transmit the skeletons of users to a distant browser.…”

NCL+Depth

“…A proposta deste artigo reflete a própria arquitetura de NCL como linguagem de cola, que agora além de sincronizar objetos de mídia no tempo e relacioná-los nas dimensões vertical e horizontal, também o faz na dimensão da profundidade.Um exemplo de integração de páginas Web com displays autoestereoscópicos é discutido por Nocent et. al em[19]. Nocent, entretanto, não integra nenhuma funcionalidade de profundidade à linguagem multimídia declarativa original (HTML), utilizando-se basicamente da API imperativa WebGL 7 para a geração das duas ou mais views necessárias.…”

Supporting Multimedia Applications in Stereoscopic and Depth-Based 3d Video Systems

“…An example of the integration of webpages with multi-view displays is presented by Nocent et al (NOCENT et al, 2012 In comparison with Le Feuvre's work, the extensions to multimedia languages and the graphics composition solution presented in the second part of this thesis are based on the LDI/LDV concept, which allow us to reach better rendering results. That is mainly explained by the fact that our proposal keeps as much occlusion information as possible while graphically compositing the different media objects.…”
