Increasing efficiency in assembly work with Augmented Reality

Customer specific and individualized products, small batch sizes, as well as increasing product complexity set higher demands for assembly work. Augmented Assembly is a research project at VTT, where AR technology is applied to increase assembly efficiency. In augmenting assembly work, the assembly worker is guided by virtual objects of components and assembly tools, and visual assembly instructions. The worker sees the augmented view through light weight head mounted devices (e.g. data glasses), and sensors provide feedback from the performed operations.

Rapid model acquisition

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.

Shake Menus research

November 3rd, 2009

Rating: +3 (from 3 votes)

Shake Menus were developed by Sean White, David Feng, and Steve Feiner at Columbia University’s Computer Graphics and User Interfaces Lab ( http://www.cs.columbia.edu/graphics/t… ). The video accompanied a paper presented at IEEE ISMAR 2009 ( http://www.ismar09.org ).

Menus play an important role in both information presentation and system control. They explore the design space of shake menus, which are intended for use in tangible augmented reality. Shake menus are radial menus displayed centered on a physical object and activated by shaking that object. One important aspect of their design space is the coordinate system used to present menu options. They conducted a within-subjects user study to compare the speed and efficacy of several alternative methods for presenting shake menus in augmented reality (world-referenced, display- referenced, and object-referenced), along with a baseline technique (a linear menu on a clipboard). Their findings suggest trade-offs amongst speed, efficacy, and flexibility of interaction, and point towards the possible advantages of hybrid approaches that compose together transformations in different coordinate systems. In our ISMAR 2009 paper, they also describe qualitative feedback from use and present several illustrative applications of the technique including game authoring ( http://www.cs.columbia.edu/~swhite/pu… ).

Augmented Reality via smartphones will rule the game

ABI Research Anticipates “Dramatic Growth” for Augmented Reality via Smartphones

According the ABI Research study “Augmented Reality: Adding Information to Our View of the World”, handheld platforms will transform the Augmented Reality ecosystem, with revenue associated with Augmented Reality growing from about $6 million in 2008 to more than $350 million in 2014. As advertisers learn to insert tags into navigation displays, mobile arvertising revenue will grow slowly, representing a large portion of sectoral revenues in the 2013-2014 timeframe.

“The new capabilities of handset platforms create an explosive opportunity for Augmented Reality technology,” explains study author Joe Madden. “Existing technology suppliers will have to adapt, as rapid growth will transform the Augmented Reality ecosystem. Today’s customized, direct business-to-business AR supply chain will continue to see incremental growth in military, automotive, and entertainment applications, but those businesses will be overshadowed by the mass-market dynamics of mobile handset application sales and arvertising revenue streams.”

The study envisions the development of global databases to store a wide variety of geo-tag information. Governments, businesses, and individuals all will contribute information into such databases, so end-users will be able to view information on notable buildings, retail sales, or special events, or simply to mark locations of interest.

Mr. Madden notes that technology advances are still required for Augmented Reality applications to proliferate. “GPS location accuracy is not adequate currently for many applications, requiring additional techniques to refine location precision for shopping applications, or for game applications in which virtual objects must be placed precisely on the display near corresponding real objects.”

This report is published under the Human-Machine Technology Research Service, which is a part of NextGen, the ABI Research emerging technologies research incubator.

Markerless Augmented Reality

This research project at the University of California, Santa Barbara presents markerless camera tracking and user interface methodology for readily inspecting augmented reality (AR) objects using a user’s outstretched hand.

Just use a webcam and your bare hand and you’re good to go.

About ISMAR

The International Symposium on Mixed and Augmented Reality (ISMAR) is the premiere international research conference for the advancement of the Art and Science of Mixed and Augmented Reality. Mixed Reality melts the boundaries between the real and virtual world to bring the power computer generated simulation into our daily lives and enhance human performance. Held in the western hemisphere only once every three years, Orlando will be the host of the most comprehensive ISMAR conference yet. The programs will covering diverse application domains, technological achievements scientific discoveries as well as creative expression and innovative design.

ISMAR 2009

ISMAR 2009 has expanded its program to present the breadth and depth of the Mixed and Augmented Reality research and application and will include research presentations, hands-on demonstrations, comprehensive tutorials and participatory workshops as well as stimulating receptions and an award banquet. Innovation workshops will be held to present the latest application domains using Mixed and Augmented Reality. The Science & Technology Program presents the latest cutting edge research of enabling technology. The Arts, Media and Humanities Program covers the creative advancements in the application of Mixed and Augmented Reality. Through comprehsive tutorials, ISMAR is inspiring the next generation student and practitioner with a cross-disciplinary view of the state-of-the-art. Receptions, banquets and special events will bring a diverse array of disciplines, cultures and sectors together for stimulating collaboration and discourse.

Attend ISMAR 2009

Ismar will be Orlando, Florida from October 19th-22nd,2009. We have new options this year to provide a more comprehensive Symposium and Expo to the diverse ISMAR community. Please carefully observe these options:

-Monday, we are offering several special academic and commercial workshops. You may sign up for just one. Registration includes admittance to the

ISMAR Expo reception on Monday evening where you will be able to mix with diverse disciplines and sectors of the ISMAR community.

-Tuesday, is the start of the 3 day ISMAR conference where you can choose one of three options.

1) the traditional Science and Technology research program,
2) the new Arts, Media and Humanities program or
3) Pioneer Tutorials, taught by ISMAR pioneers. Conference registration also includes the conference reception Tuesday night, Keynote presentations and the Wednesday night awards banquet.
