Nice. May I ask you how you did the project shown at your blog? In the
blog post Touchscreen Jukebox you are talking about touchscreens. Only
how is this working exactly. Really touch screen? Sounds like, a nice
way to do gesture-based interaction.
hello Weyert,
The screen is not really touch screen. It is an acrylic surface, with a
camera behind it. This camera sees the fingers, and this image is processed
by flash, using the code I published in the blog. Of course, the light must
be carefully done, so you can get the fingers with a good
I have figured out how to make flash work as a multi-touch system... I
am coding it now...
it is so darn simple...
it just came to me after watching a video on how to make your own
multi-touch input device using a webcam a piece of white paper and a box
to block most of the light so the cam
Hi,
Mario Klingemann demo'd something like this at FlashOnTheBeach 2007
- have a look at quasimondo.com to see the 2D or not 2D lecture - not
sure if he released any code though?

I was actually thinking of Mario's lecture at FoTB 2008 where he used
very similar algorithms to read square barcodes (whatever those things
are called) from a webcam. Not multitouch, but there's a lot of
similar code (spotting areas of colour, eliminating noise).
Worth a look, Anthony.
Funnily
To my knowledge all flash integration for multi-touch has been made
possible by using flosc by ben chun, or with OpenCV and touchLib;
however, what I am proposing is that it is possible directly through the
use of the flash player and a simple cam rig. I think that it should be
possible, and
Yeah, I absolutely get the idea (as I said, we were discussing it
yesterday - with reference to an infra-red camera, but same
principle). Check out Mario's stuff, there are areas-of-colour
recognition algorithms there which will be of help, I think.
Cheers,

That's a great tip. :-)
Pocket change? Definitely not... we're not made of money either!

hello,
I've ported a blob detection Processing library, blobDetection, to AS3. It
is slow, but maybe you can optimise it.

Using BitmapData.getBoundsRect(), I started BitmapBlobDetection. It works
faster:

great info...
Before I peruse through your library, I have a few questions. Do you
test for the largest circle or rectangle that can fit in the blob? Or
for the centre point of the blob? or do you look for a circle or
rectangle that encapsulates the blob, and then possibly locate an
hello Anthony,
you can set some parameters when using the library, to get what you want.
For example:
- you can set what will be the maximum size of a blob. If the blob is
greater than the maximum size, the algorithm checks if there is really a
large blob, or several small blobs. If the blob is
Thank you very much for the zip... I look forward to nosing through it.
