These last weeks I’ve worked on a prototype to get a multitouch version of Google Earth with Flex/AS3. Now I’m looking for “alpha testers” :D

In order to use this Flex MTGoogleEarth , you need :
- Touchlib + Flosc or Tbeta
- Flash player 9
- Web browser (compatible with GE plugin)
- Last version of Google Earth Plugin (r5.0)
- Application files embedded in zip file,
- Internet…

How to :
- You need to install last release of GE plugin (r5.0) which can be downloaded on this page.
If a previous release of GE plugin is already installed on your computer, you must uninstall it before.
- Unzip content of zip file on your disk and launch “GoogleEarthTouchable.html” file with your web browser.

Gestures :
- One finger : drag the earth
- Two fingers : rotate the earth or change distance from camera to “look at” point.
- Three fingers (two static and one moving up or down) : change tilt angle.
Demo here

What you need to know :
- This application doesn’t work with simulators, MT Tables only (because of focus problem).
- This application must be launched in a web browser.
- This application was tested with IE6 and IE7. No guaranty for others browsers (IE8 is not supported by GE plugin).

If you test this app, please let me know :
- OS used,
- Web browser used,
- problems (if you have problems),
- enhancements

I’ve been working on an application called CHALKmt which is a multi-touch chalk board application that I made using AS3.

CHALKmt allows multi-user/multi-touch interaction of Chalk Boards that can be scaled/rotated/moved and even wiped clean!
See the video below for an introduction to CHALKmt....

There are 2 versions available for download (Wall & Table).
The difference between the 2 is the number and position of the ‘+’ buttons that add the Chalk Boards to the screen.
The Wall version (ChalkMTWall_Beta 1.0.rar) has 2 top left & top right, while the table version (ChalkMT_Beta 1.0.rar) has 4 on each corner.

This just makes the layout easier for the different Multi-touch setups people are using.
I hope you like it, and as always your feedback is welcome

I’m a Bachelors student working on my final year project, which is concerned with creating a number of AS3 classes which can be used to create MT interfaces. However, the framework will come bundled with a C++ server I’ve written which can be embedded into programs to allow the (essentially dumb) UI to communicate bi-directionally with C++ backend programs (or theoretically any other language) running in the background, driving the UI via position messages sent over TCP. Functionality will be included to define interfaces by an XML config file which contains the locations of (presently local only) source media (images, movies, audio, data), with (limited) formatting via XML attributes, and menus may be defined here, with buttons that relay messages provided in the config file to the backend app.

Bit of a mouthful to explain, hope I got the point across. Its going pretty well and expect to get it in a good working state within a month. Anyway, just wanted to check if there was anything similar to this that exists already, and to gauge if there is any interest in seeing this as an open-source project - though I am completely unsure of university policy on this, I’d have to check that out first.

Cheers!

I’ve worked, for the past two months, on a small app in order to learn AS3 and to test a few multitouch concepts like rotate/scale objects, scaled desktops, multiple layers displaying augmented information and interaction between components.
I’ve built it upon many works and ideas, like NUI AS3 framework, LagerKoller’s googlemap app or Jeff Han’s multilayers map system.

I’ve uploaded 2 videos for a short demo. Functionalities and interactions are still really simple but i have to say i don’t have a lot of time to work on this and there is still a lot of bugs. I’ve also made some quick tests with features like gesture recognition or flickr search from a place selected in google map.

PS: how can I embed youtube videos in this post ? i don’t understand what is the “youtube string” :(

I am writing an AS2 client that is reading messages from the socket. Problem is since, CCV sends messages at a fixed rate to nnotify that it is alive ( ALIVE messages ), I wish to know the Message format for a touch interaction. Or basically, the message that is sent when the user touches the screen( single finger touch). I have read the documentation, and yet find it hard to understand. I would glad if someone pasted the message format here.

Thanks

But the flv videos in the app works fine, they could be move, scaled or rotated by simulator.

This problems confused me for several days and cannnot get it work right. So, any suggestions?

Thanks very much!

UPDATED 2009/12/15:
Problem solved.
The ImageObject.as codes had some thing wrong. Here I uploaded a new file to replace it and everthing will work fine.

Then I tried doing exactly the same but replacing the touch drag by mouse drag. Still there is lag, but less (I guess this is because there r a lot more mouse events than the tuio event rate). Anyhow, there’s still a big difference when i take the children out opposed to children in. So this seems to be a Flash issue rather than a touch event rate issue (as the multitouch drawing app went fine). Increasing the framerate from 30 to 60 shows an even bigger difference in dragging movieclips with and without child movieclips.

I can’t be the first one facing this problem?
