WPF Multitouch Framework

2008-05-19T09:53:57-05:00

The past view months we have worked on a WPF Multitouch Framework based on the TUIO protocol.

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!

CsTI - CSharp Touchlib Interface

2007-05-14T06:25:49-05:00

I’m working on something i call CsTI. It is a C# Touchlib Interface.

It will - once completed - allow you to write C# code to create an interface for your multitouch application. The basic template for the application is that you override the fingerDown, fingerUpdate and fingerUp methods that is received from touchlib. This might lower CPU usage as not so much data has to be passed around - because touchlib is semi-part of the application.

Also it would make it very easy to write a windows application that utilizes these touch events. Looking at WPF - the vista interface model (windows presentation foundation) that allows direct3d to be run in a normal windows app, makes it possible to create some nice 3d interfaces.

the project is still in a proof of concept phase...my c# is a bit rusty...but i know it can be done. this will probably be used in my 3rd year computer science project, something in the direction of my previous post here.

another aim of the project is to attract the not-so-hardcore programmers to get into writing multitouch applications.

.NET multitouch framework

2007-07-01T17:12:57-05:00

so i’m on to my next project...CsTI was just a small step into this project. i also decided to start this project to find out if my implementation of CsTI is correct..

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

Button but = new Button();
etc...

but allows for touch interaction, like

TouchButton but = new TouchButton();
etc...

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.

MTV multiplemice for other frameworks

2008-09-08T13:18:43-05:00

Well, I think that the title says a lot, but here is the question:

Is it posible to use in any way the multiple mice input used by Multitouch Vista in another TUIO based WPF framework?

For “any way” I mean that someone could write a wrapper after adding a reference to the MultipleMice.dll into any project, or better, write a library that takes this input and sends it through TUIO. I really think this library is very usefull, specially for someone (like me) who hasn’t a MT Table, and wants to star writing MT Apps.

Multitouch Vista Shell Videos (updated)

2008-02-22T17:52:45-05:00

Finaly I made a video of multitouch shell I’m working on.
On this video you can see a normal windows applications that can be rotated and moved in “multitouch"-style.

Silverlight + Multitouch = Surface?

2007-07-12T06:35:48-05:00

Hey guys, I just wanted to make a small demo available to the community… it is a Visual Studio 2005 Solution, which shows that Silverlight will be a great platform to develop MT apps on. I am planning on implementing TUIO support which will give us real-time input, but could really use some help since I am new to Silverlight.

Here is the source in VS2005 format

Note: You can find the solution in the clientbin folder, you must have VS 2005 to compile (Orcas not required)

Bespoke Multi-Touch Network Gateway

2008-08-18T16:43:21-05:00

Hello all,

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?
