SurfaceToTuio is available as source code only (there is no executable). However, you can just upload the SurfaceToTuio folder to your Surface, doubleclick the Visual Studio project and compile it in the Surface’s Visual Studio right away.
Figure 1: The Virttable’s display with (right) and without (left) the chosen IR blocking foil.
Some time back, I’ve bought some infrared blocking foil for the Virttable from the German foil store Ifoha. Infrared blocking foil is an approach for the blocking of ambient infrared light (e.g. from a light bulb or daylight) ONLY in a FTIR multi-touch setup as it blocks light that comes from above the table. I.e. in DI your hands reflect light that would be blocked by an IR blocking foil. Read the rest of this entry »
BumpTop is a Windows Explorer-like application that offers intuitive gestural multi-touch interaction paradigms with piles of files and folders. Additionally, it has a 3D space in which you can navigate and decorate your workspace. You can copy files to and from your usb stick, to Facebook or you can send them via mail. It seems to be integrated well in Windows 7.
I am going to present a few projects on my blog in which I collaborated in one or the other way. The project UNFOCUS – FOCUS is a multi-touch and TUI project that makes use of our fiducialtuioas3 classes.
Important: I discontinued the work for fiducialtuioas3. If you are starting a new project, consider using our new AS3 Tuio library Tuio AS3. As you most certainly came here because you want to use fiducials in AS3 find the according Tuio AS3 fiducial howto here.
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.
Sound design has been an issue that I have disregarded so far in my multi-touch applications. However, a good sound design should be very beneficial for user experience in a multi-touch installation.
Actually, I have not configured the compilation of the Touchlib on my own, yet. But I have heard that it should be a hell of complicated. As I came upon the website of the original author of the Touchlib in which he gives a lot of hints, I wanted to post his page here: How to Compile the Touchlib.
Important: I discontinued the work for fiducialtuioas3. If you are starting a new project, consider using our new AS3 Tuio library Tuio AS3. As you most certainly came here because you want to use fiducials in AS3 find the according Tuio AS3 fiducial howto here.
In his Bachelor thesis Frederic Frieß enhanced the original Touchlib TUIO AS3 classes with support for fiducials (or to speak in TUIO terms with support for /tuio/2dobj messages).
Thus, the Touchlib’s TUIO classes can simply be replaced with Frederic’s classes and everything should still work as before. However, there is one slight change in the package structure: the TUIO classes are now lying inside the package tuio and not in the package flash.events.
I have made Frederic’s Tuio Fiducial AS3 classes available on Google code in a project called fiducialtuioas3.
If you want to use reacTIVision fiducials in Flash, Flex or Adobe Air you are heartily invited to use these classes in your private and professional project.
