Nudging the world toward better pictures and video

on Comments (2)

An excellent article on FXPAL’s NudgeCam application recently appeared in MIT’s Technology Review. NudgeCam encapsulates standard video capture heuristics, such as how to frame a face and good brightness characteristics, in order to provide guidance to users as they are taking video, using image analysis techniques such as face recognition,  as to how to adjust the camera to improve the video capture.

For its size, FXPAL has surprising breadth and variety of expertise. The NudgeCam work resulted from a collaboration between Scott Carter, whose expertise is in mobile and ubiquitous computing,  and John Doherty, our multimedia specialist, who knows all the standard video capture heuristics and many more. John Adcock brought image analysis techniques to the team, and 2009 FXPAL summer intern Stacy Branham contributed her human-computer interaction expertise.

A different application, also developed at FXPAL, supports rephotography in an industrial setting. Rephotography is the art of taking a photograph from the same location and angle as a previous photograph. Continue Reading

pCubee: a interactive cubic display

on Comments (2)

Our friend Takashi Matsumoto, (who built the Post-Bit system with us here at FXPAL) built a cubic display called Z-agon with colleagues at the Keio Media Design Laboratory. Takashi points us at this video of a very nicely realized cubic display (well, five-sided, but still). It’s called pCubee: a Perspective-Corrected Handheld Cubic Display and it comes from the Human Communications Technology Lab at the University of British Columbia. Some of you may have seen a version of this demoed at ACM Multimedia 2009; it will also be at CHI 2010. Longer and more detailed video is here.

Generating 3D models from webcams

One highly inconvenient thing about working with virtual worlds or 3D content in general is: where do your 3D models come from (especially if you’re on a budget)? A talented but (inevitably) overworked 3D artist? An online catalog of variable quality and cost? Messing around yourself with tools like SketchUp or Blender? What if you want something very specific, very quickly? The MIR (Mixed and Immersive Realities) team here at FXPAL is very interested in these questions and has done some work in this area. Others are working on it too: here’s an elegant demo from Qi Pan at the University of Cambridge, showing the construction of a model with textures from a webcam image:

ARdevcamp: Augmented Reality unconference Dec. 5 in Mountain View, New York, Sydney…

on Comments (1)

We’re looking forward to participating in ARdevcamp the first weekend in December. It’s being organized in part by Damon Hernandez of the Web3D Consortium, Gene Becker of Lightning Labs, and Mike Liebhold of the Institute for the Future (among others – it’s an unconference, so come help organize!) So far, there are ~60 people signed up; I’m not sure what capacity will be, but I’d sign up soon if you’re interested. You can add your name on the interest list here.

From the wiki:

The first Augmented Reality Development Camp (AR DevCamp) will be held in the SF Bay Area December 5, 2009.

After nearly 20 years in the research labs, Augmented Reality is taking shape as one of the next major waves of Internet innovation, overlaying and infusing the physical world with digital media, information and experiences. We believe AR must be fundamentally open, interoperable, extensible, and accessible to all, so that it can create the kinds of opportunities for expressiveness, communication, business and social good that we enjoy on the web and Internet today. As one step toward this goal of an Open AR web, we are organizing AR DevCamp 1.0, a full day of technical sessions and hacking opportunities in an open format, unconference style.

AR DevCamp: a gathering of the mobile AR, 3D graphics and geospatial web tribes; an unconference:
# Timing: December 5th, 2009
# Location: Hacker Dojo in Mountain View, CA

Looks like there will be some simultaneous ARdevcamp events elsewhere as well – New York and Manchester events are confirmed; Sydney, Seoul, Brisbane, and New Zealand events possible but unconfirmed.
