Johannes Luderschmidt’s Blog

It has been a while since I gave a presentation about Natural User Interfaces at the webandwine event by the company mediaman on 7 May 2009. However, I found those two quite nice pictures of my presentation on the blog of Frank Hamm that I wanted to show here:

fiducialtuioas3 now supports pure TUIO messages via TCP.

The bridge TUIO → Flosc → Flash is now being replaced by the bridge TUIO → udp-tcp-bridge → Flash. The latter method renders the transformation of TUIO messages to a proprietary XML dialect obsolete. That speeds up the connection of the TUIO producer (e.g. Touchlib, CCV or Touché) to the Flash application itself (e.g. Vispol, Volvelles) and thus reduces lag.

Hopefully, TUIO producers will support the output of TUIO via TCP natively soon (as far as I know at least Touché does). However, you are on the safe side if you use memo’s cross platform, open source, C++ UDP TCP bridge.

The TCP tuio AS3 classes have been downloaded and adapted for the additional support of fiducials from Touchgateway.

So you can download fiducialtuioas3 in both flavors (via Flosc and via pure TCP TUIO) from the fiducialtuioas3 google code repoitory (on the right).

In the nuigroup there are a threads about fiducialtuioas3 here and here.

I recently wanted to use a FireWire camera (a Pointgrey Firefly MV to be precise) with a white MacBook that ran with Windows XP SP3 in Bootcamp. That actually is no problem but I got into problems when I wanted to achieve higher framerates than 15 Hz. Then I realized that the only Async/Isoch mode that the MacBook offered was S100 (which as far as I know) means a downstream of 100 MBit/s. This is four times slower than the 400 MBit/s that FireWire 400 is capable of.

Recently, i came across a few videos of video projections on buildings and have been very intrigued. However, they seem to be studies made with After Effects. This is my favorite video:
