this project does not have a name *yet*

and here is the description:

it’s basically the .net framework, but allows for multitouch interaction.
it uses touchlib and CsTI
it’s written entirely in C#
it’s WPF(Windows Presentation Foundation) or .NET 3 based - so it won’t work on .NET 2 btw

it’s a framework of custom controls. ie. image/button/video/etc. for .net
so i aim to enable people to write code, like they would in c#, like

but allows for touch interaction, like

That means the second code example will allow you to press the button WITHOUT simulating the mouse, also write your own code for what to happen when one/two/three/etc fingers are on one image. WPF allows for animation/layers/ and a bunch of other cool stuff.

i will have a working prototype of a multitouch image app (like white’s flash app) within the week.

i’ll appreciate if anyone could give some feedback on the idea.

I’ve just posted version 4.1 of the Bespoke Multi-Touch Framework. This release includes improved calibration, a mouse emulator, and a network gateway. The network gateway uses Open Sound Control (OSC) and supports a simple set of OSC methods very similar to TUIO. I have a detailed post describing the gateway at http://www.bespokesoftware.org/wordpress/

I’ve tested the gateway with FLOSC and it appears to work, though it seems like there might be byte order issues. This might be from my implementation of OSC, or I might simply be interpreting the output from the FLOSC test client incorrectly. My C# client implementation works like a champ, but that’s to be expected as I’m using the same serialization code on both ends of the connection. I’m looking for some feedback from someone who uses Flash/FLOSC. Anyone interested?

We would like to invite you to download this easy to use framework, try some things and share your
experience with us.

We have included a quick start guide and a demonstration application.

It is nessacary to use Visual Studio 2008 and the .Net Framework 3.5.
We also used Microsoft Expression Blend, but that isn’t specially needed.

Soon we will add a quickstart video on youtube so you can see how everything works.

This is a beta version so not al code is already optimized, and some writelines have to be deleted.

Good luck with the framework and we hope to hear from you soon!

Edit:
We have made a google code project: http://code.google.com/p/multitouchframework/
At this page a SVN checkout is available and you can see an introduction video about our framework.

Edit 2 (06-06-2008):
We have made an real time demonstration of our framework!

First we show you the “scatterview” , then a short demo of some multitouch controls and at the end
we demonstrate an example of a control room

Edit 3 (11-6-2008)
New version online with improved scale and rotate, the possibility to show the position of your fingers and some bug fixes!

3D User Interfaces in Video Games with the Bespoke 3DUI XNA Framework
Joseph LaViola and Paul Varcholik of the University of Central Florida demonstrate a series of simple video games that utilize concepts from 3D user interfaces and virtual reality. The demos let users play music with virtual instruments, battle Boba Fett, dance, and play 3D Pacman. These demonstrations have been built using the Bespoke 3DUI XNA Framework, an open-source software library based on the Microsoft XNA Game Studio, for developing games and simulations using 3D user interfaces. The framework’s goal is to make it easier for game developers and hobbyists to create mainstream games that give users rich, interactive experiences that can mimic the real world or provide magical, larger-than-life experiences. The key feature of the framework is that it provides a set of software components that are essential to supporting spatial 3D interaction, such as stereoscopic rendering, 6DOF optical head tracking, Wiimote 3D motion controller support, and an extensible 3D gesture recognizer.

Single point
--------------
Press and hold - Mouse move
Press briefly - Left click

Two points
-------------
Two brief touches next to each other—Move the mouse and double click
Press and hold right point and tap to the left—Left click
Press and hold left point and tap to the right—Right click
Press and hold left point and drag right point vertically-- Mouse wheel
Press and hold bottom point and drag top point horizontally - Alt-tab (not actually a mouse command, but seemed useful)

I’ve posted a couple of YouTube videos demonstrating the emulator. The first is just on the Windows desktop, and the second video is a brief game of Starcraft.

Which one is the best one to use? Because I don’t have VS2008 or .NET3.5 (WPF), nor a multi-touch display (:/) I am unable to try all of these out and decide for myself which has the best features, control set, etc.  Are all these just derivatives of TouchLib?

Would all of these work with any multi-touch capable device? I’m looking at the TouchKit (http://nortd.com/touchkit/).

I would like to begin looking into creating multi-touch apps, but trying to pick a starting point seems to confuse me! Especially with the emergence of frameworks like Lux (http://nuiman.com/log/view/lux/) which appear to be cross platform.

Your thoughts would be appreciated.

thanks,

I guess we’ve pretty much been awed by the recent apps built for the MS Surface using their Surface SDK but too bad its only released to their partners but I’ve recently been exploring using WPF for MultiTouch and here are some projects I found that has their source codes from codeplex:

http://www.codeplex.com/Tangibilis - TUIO
http://www.codeplex.com/MultiTouchVista - This one has already been showcased
http://www.codeplex.com/wpfmt - WPF Multitouch Demo
http://www.codeplex.com/irtaktiks - WPF + XNA

FYI, I have yet to try any of the codes above so no gurantees but just give it a try!

APPLICATION SUMMARY:;

Audio Fingers is an multitouch app that plays multiple music files and allows effects modules to be inserted into the audio chain.
The screen will have a browser window to select wave files from and you’ll simply drag & drop a wave files into the play area and each one turns into a “wavepod”.
From another part of the screen you’ll be able to grab an effect module and dock it to the wavepod.
How close the effect module is the the wavepod determines the effect send level.

The wavepod has 6 controls:
Play
Pause
Stop
Volume
Mute
Loop

The effects modules are:
Bass
Treble
Phaser
Reverb

I just got a start on graphics elements in Illustrator/Photoshop.
Here’s a rough idea of what the interface will look like.
When it’s done it will be available for download as freeware on audiofingers.net
