A Technical Preview of Mirror Worlds

admin — Thu, 29 Oct 2009 00:00:04 +0000

In this demo visitors will see mobile augmented reality software overlaying virtual information such as social networking data, user generated content, and advertising with the world around them. This demo illustrates how knowledge of the location and surroundings of a mobile user can be leveraged to create virtual augmentations that are integrated with the physical …

Watercolor Inspired Non-Photorealistic Rendering for AR

admin — Wed, 29 Oct 2008 16:36:23 +0000

Abstract Non-photorealistic rendering (NPR) is an attractive approach for seamlessly blending virtual and physical content in Augmented Reality (AR) applications. Simple NRP techniques, that use information from a single rendered image, have been demonstrated in real-time AR systems. More complex NRP techniques require visual coherence across multiple frames of video, and typical offline algorithms are …

Uncertainty Boundary for Complex Objects in AR

admin — Sat, 08 Mar 2008 16:38:53 +0000

Abstract Registration errors between the physical world and computer-generated objects are a central problem in Augmented Reality (AR) systems. Some existing AR systems have demonstrated how to dynamically estimate registration errors based on estimates of spatial errors in the system. Using these error estimates, these systems also demonstrated a number of ways of ameliorating the …

Prototyping the “Pit Experiment” in ARSecondLife

admin — Thu, 27 Sep 2007 17:09:15 +0000

This AR Stage is used to prototype an ongoing research project to study Presence in Augmented Reality application. A virtual pit, superimposed on a live video feed, is presented to participants, which perceive the scene through a Head Mounted Display. Chromatic keying allows perfect blending, as physical objects above the pit block virtual objects (Quicktime …

AR Stages

admin — Sun, 23 Sep 2007 16:55:42 +0000

In Augmented Reality authoring based on Massive Multiplayer Online Worlds, AR experiences are less like “applications” that are designed, loaded and executed, and more like an “installation” that is created, evolved and performed in a defined area in the virtual world. We call these areas AR stages, in similarity to a theatrical stages were performances …
