experiment 01 : weaving pattern

this is the simple weaving pattern i made which i painted black color onto the paper ,
the AR tag is randomly from website

Exerimenting AR with projectors

Finally got a hold of 2 projectors (thanks to Belle and Ball)
and been playing with them extensively and it seems
to me that AR and projector do not mix together well. Here
are the details of the more relevant experiments I done:

1.Mixing AR with projector's image:
(single projector and computer setup)

An AR tag (paper) is pasted onto the make-shift screen. Ar program is then run and the tag was detected fine (left image).

The projector is turned on and the image projected onto the screen. Immediately, the program can no longer detect the tag (right image).

Conclusion:
Actual print out AR tag can not be mix with projector's projection. The light intensity of the projector's image is way too high for the web-cam to see through (notice image on the right, the image on the computer's screen is pure white).

2. Using projected image to display AR tag
(single computer, single projector)

The pattern displayed by the projector on to the screen, the AR program is then turn on to see whether the tag can be detected in this case.

Conclusion:
It works, but the camera distance has to be adjusted somewhat.




Notes: projecting the AR program itself onto the screen with the camera pointing to the same screen/direction is a bad idea as it produces infinite looping effect.














3. Double projector
(2 computers, 2 projectors)
Similar to experiment #2, but this time with 2 projectors and computers, one projecting the AR program, the other the AR tag.
Conclusion: The light intensity of the combined projector images is too high, the webcam cannot see anything but pure white.

4. Using computer to display AR tag #2
(1 projectors, 2 computers)

Similar to experiment #2 but this one uses a single projector and a computer dedicated to display the AR tag onto the screen. The AR program is run on the 2nd computer (no projector hooked up).

Conclusion: It works out well as expected, and the best part is there is no annoying infinite loop effect .



5. Animated Tag
(same set up as previous)










same set up as previous experiment, but this time the tags are put under some simple motion- tweening animation (flips, move, scale, and 3D rotation)

Conclusion: Though it seems to work somewhat, the AR program is only able to detect the tag while it's not under transformation (scaling, etc). Which would indicate that the detection time is pretty slow and cannot keep up with sudden movements. And just for the record, 3D rotation do not work at all. In the end I think it would work if the animation is slow and simple enough (keep it to translation and rotation)!

6. Integrating real world object
(one projector, 2 computers, an object)










Same 1 projector set up, but this time the whole screen is flooded with AE tags, then a white paper cube is integrated into the set up by placing it in front of the projected image.

Conclusion: The AR program will detect pattern as long as it's on a FLAT surface. This set up works, however the camera has to be readjust in order to take into account the protruding surface---it seems that the program will start having difficulty detecting the tag if it's smaller than 2-3 cm square (like wise, the camera shouldn't be too far from the tag; about half a meter away).



Well from my experiments, it would appear that layering projector's image is not a good idea in any case, AR's lighting condition tolerance is much more sensitive than originally perceived. Second, it would be really difficult to exactly project a pattern onto a surface as in experiment #6. I had skimmed over Max/Msp and projection mapping technology. However it might takes me a long time to learn and get it working with AR (currently, a free projection mapping tool that I can find do not support Flash files, only Quicktime clip ( http://hcgilje.wordpress.com/resources/video-projection-tools/). Projector's image is merely 2D display of what was on the computer screen, thereby, it would be extremely difficult achieve 3D, or even an illusion of 3D projection with a projector (though the image inside AR program appears to be 3D, the desktop image---what is projected by the projector---is decidedly 2D). Right now, experiment #5 and #6, imperfect and imprecise as they are, holds the most potential and are the most plausible within the time frame.

I still have the 2nd projector for the weekend, so please tell me what else you want me to try with 2 projectors. I sincerely apologize for not showing up today, and for reporting my progress so late (went out to see the doctor).

The NeoCube interaction cool design

ENVISION - Step into the sensory box

Battle of Branchage - Architectural Projection Mapping

Tangible hologram projector

AA Visiting School Paris


It's 10-days intensive design workshop
from Monday March 21 to Thursday March 31, 2011.

And quite pricey:

Workshop (£600)         30,000 THB
Air Ticket              60,000 THB
Accommodation           30,000 THB
Living Expense          30,000 THB
4-days Trip to London   30,000 THB
TOTAL                  180,000 THB

I'd say around 180,000 THB ++
for 14-days trip (10 days workshop + 4 days in London)
Let me know if you are interested...

It looks quite interesting and should be a really good
opportunity if you get a chance to participate.

Magnus Larsson: Turning dunes into architecture

For an ambitious landscape design project, Magnus Larsson, a student at the Architectural Association in London, has proposed a 6,000km-long wall of artificially solidified sandstone architecture that would span the Sahara Desert, east to west, offering a combination of refugee housing and a "green wall" against the future spread of the desert.



Larsson's project deservedly won first prize last fall at the Holcim Foundation's Awards for Sustainable Construction held in Marrakech, Morocco.
One of the most interesting aspects of the project, I think, is that this solidified dunescape is created through a particularly novel form of "sustainable construction" – that is, through a kind of infection of the earth.
In other words, Larsson has proposed using bacillus pasteurii, a "microorganism, readily available in marshes and wetlands, [that] solidifies loose sand into sandstone," he explains.





The "architectural form" of the resulting solidified sandscape is actually "derived from tafoni," Larsson writes, where tafoni is "a cavernous rock structure that formally ties the project back to notions of aggregation and erosion. On a conceptual scale, the project spans some 6,000km, putting it on a par with Superstudio's famous Continuous Monument – but with an environmental agenda."
