Photorealistic Rendering for AR

/in , , , , /by

Probably the most impressive examples of AR I have seen in a while. Finnish VTT Team has done some impressive work in the past and this example is nothing sort of spectacular in my book. The video was recorded a Dell laptop with a Quadro FX 3700M video card, a Core Duo processor and a basic Logitech webcam. The graphics itself is drawn using OpenGL and GLSL.

VTT’s description of the above video is:

Photorealistic rendering for Augmented reality. Uses soft shadows, indirect lighting and image quality matching. Various materials like glass, chrome or plastic are possible. Lighting is automatically determined from a ping pong ball.

For us it is a demonstration how realistic things can appear with modern hardware – albeit not of the ‘handheld’ type – and GFX APIs, hinting that the more we push the envelop and exploit technological advancement, the more immersive things will appear.

Storytelling and AR

/in , , /by

Kat Austen in New Scientist’s Culture lab presents a very interesting post on AR books. By AR books we – currently – refer to books that have some added information in the form of extra visuals which are projected through a a web-cam-equipped computer, tracking the book’s features, such as pictures, QR Codes etc. The post mentions  some of the books that appeared this year, such as Fairyland Magic from Carlton Books and Tyrone the Clean’o’saurus from Salariya Publishing and presents the author’s experience with them. Kat also mentions Camille Sherrer’s Souvenirs du Monde des Montagnes along with a video bellow.

We cannot help but agree with the author’s overall assessment that, overall, the current AR books have an element that makes them impressive initially but they eventually lose their grip on the reader – particularly the young ones. Moreover, the set-up required usually to achieve those augmentations is not exactly convenient, especially when you simply want to ‘dazzle’ your kid with an elaborate story.

It so happens that this is our view on many matters of current AR. Things are impressive on first sight but when you pass the ‘wow, what’s this!’  point, they often fall short. We are planning  to investigate in the future, the sense of immersion of various AR book paradigms through user assessments.

Total Immersion CEO on AR

Bruno Uzzan, CEO and Co-Founder of Total Immersion, speaks about the past, present and future of Total Immersion during his keynote at AR Immersion 2010, November 9, Los Angeles, CA. (Source – T.Immersion blog here)

Interesting points in our humble opinion are:

  1. The ‘cuckoo’ talk looks cool and dare I say kinda funny (Video1- 3:12)
  2. Mentioning crudely the impact CPUs (and dare we say GPUs) and 3D GFX APIs have on modern AR
  3. The need for camera vision for modern mobile AR
  4. That the quality of graphics affects immersion (ok, it is kind of implied)
  5. Wireless baud rates
  6. Smartphone worldwide usage and projections

We feel points 2,3 and 4 are of paramount importance of the current shape of handheld AR. In fact the quality of graphics and the effect this has on the sense of presence of the users has been a key part of our past research.
