Multi-touch applications with Flash

I’ve written in a previous post that there is the idea of a standardised technique to connect multi-touch hardware to multi-touch software via TUIO. As we want to concentrate on Flash as visualisation and interaction layer for our digital volvelles I will present a Flash AS3 API for multi-touch with TUIO in this and further posts.

The touchlib project from the NUI Group is a collection of software tools for the realisation of a multi-touch table. It provides tools like digital image processing for the tracking of fingers on a multi-touch screen, a TUIO server and so on. It additionally provides a Flash AS3 library in order to process TUIO messages inside of Flash and to provide standard interface elements e.g. sliders.

All Flash applications that are being built with touchlib’s AS3 library can not only be used with a TUIO enabled multi-touch device but also with a mouse. This offers advantages in the development process as you do not (necessarily) need a multi-touch device in order to use your application. This will be very useful if more than one person are involved in the development process (as in our case a designer, a Flash developer and a hardware developer are involved) because everyone can get a feeling for the interaction with the application without the need for a colocated multi-touch device.

The touchlib project including the mentioned AS3 library can be downloaded here. The AS3 library with demo applications can be found in the following folder within the zip file: touchlib -> AS3 -> src.

    We’ve created a wm_touch to tuio interface to allow windows 7 devices to run the flash touch applications. Check out this video. http://youtube/computable78

  6. […] I have used it to develop the multi-touch parts of a TUIO-driven Flash multi-touch application. The SMK-15.4 comes with drivers for Windows and for the Macintosh. Additionally, for Windows there is a small application available that tranlates Stantum multi-touch events into TUIO events that can be (more or less easily) processed by a Flash Actionscript application.
