ProFORMA: Probabilistic Feature-based On-line Rapid Model Acquisition

Off-line model reconstruction relies on an image collection phase and a slow reconstruction phase, requiring a long time to verify a model obtained from an image sequence is acceptable. University of Cambridge Engineering Department proposes a new model acquisition system, called ProFORMA, which generates a 3D model on-line as the input sequence is being collected. As the user rotates the object in front of a stationary camera, a partial model is reconstructed and displayed to the user to assist view planning. The model is also used by the system to robustly track the pose of the object. Models are rapidly produced through a Delaunay tetrahedralisation of points obtained from on-line structure from motion estimation, followed by a probabilistic tetrahedron carving step to obtain a textured surface mesh of the object.

See-through Displaying Method for Markerless Augmented Reality


ARScope is a novel interface for various applications of augmented reality. A superimposed image is projected by a head-mounted projector onto a hand-held device covered with retro-reflective material. The background image is transformed into an image that is suitable for the user’s current viewpoint without the use of markers or a head-tracking device.

Digitial Airbrushing with Spatial Augmented Reality

This is the video that accompanied Michael Marner’s poster at ISMAR 2009. The system Michael developed allows a user to digitally airbrush onto physical objects, with the ‘paint’ being projected onto the objects. The user is given a stencil, which can mask areas of the paint. The stencil tool is a board, but the actual shape of the mask is virtualised, which means you can do things like allowing the user to draw their own stencil to accomplish a specific task.

The key point in this video is building the user interface from physical tools that are augmented with digital information. This idea has uses well beyond the scope of a painting application.

Augmented Reality Texture Extraction Experiment

This is an AR-based experiment that enables the user to lift textures from real-world objects in live video and apply them onto 3D objects that are overlayed on top of them. Only box primitives are supported here, but the general idea could be extended to other types of 3D primitives or potentially even more complex objects with some clever image compositing and UV mapping (a-la Photosynth, I guess).

New ways to interact with augmented reality and its functionalities.
In this scene, is possible to control the objects inside the flat by clicking them like what is happening on this demo with tv and with the nice lady that’s growing up to show us with detail the dress she’s wearing. Imagine to connect this system with your shopping online or… build it around AR.

Yep. This application could be deployed for web :)

Haptic ring touching virtual creatures in mixed reality enviroments

Tokyo Institute of Technology and the University of Electro-Communications have created the cutest AR creature to date. In the last SIGGRAPH conference they have presented the following poster, discussing a haptic ring that let you pet virtual creatures (VC) and enable virtual creatures touch you.

Abstract

“We propose a new method for Symmetrical Haptic Interaction System with Virtual Creatures (VCs) in Mixed Reality (MR). In this work, we can interact VCs directly, not only through some tools but also with our fingers. If we touch VCs, we can see and feel their reaction. On the other hand, if VC touches us, we can feel the action from an image and a counterforce. It also can be experienced by a lot of people at once. Our system enhances the sense of presence and variety of expressions of VCs. At the same time, our system does not disturb manipulations of real objects by our fingers. Therefore, you can also manipulate the real part of the Mixed Reality environment intuitively. Our system is ideal haptic interface for Mixed Reality and brings us a totally new form of entertainment.”

Augmented Collaboration in Mixed Environments

Augmented Collaboration in Mixed Environments (ACME) is a mixed reality teleconferencing application based on Second Life (SL) and the OpenSim virtual worlds. Augmented Reality techniques are used for displaying virtual avatars of remote meeting participants in real physical spaces, while Augmented Virtuality, in form of video based gesture detection, enables capturing of human expressions to control avatars and to manipulate virtual objects in virtual worlds.

Michael Bruce Sterling is an American science fiction author, best known for his novels and his seminal work on the Mirrorshades anthology, which helped define the cyberpunk genre.

Due to his curiosity about the near future, he immersed him self into the laboratories to learn more about the Augmented Reality possibilities. Now a days, he’s one of the top keynoters about this topic.
