Adding sound

The concept of WalLust like the name suggest is Lust. Besides a graphic approach, adding sound to the context will help solidify the idea. I did some research on flash demo that cater both sound and interaction. Bloom adapted from Iphone app by Seth Sandler is the perfect example.

Demo


I search for the source code and come across this. I am yet to try this on another flash file.

Webcam Problem

At first we use Microsoft webcam but since we are having the installation in a low light condition, we soon discover that an IR webcam would boost the detection in dark. We then switched to PS3-Eye and it works.






Importing Flash Demos

The problem with Touchlib is the limited amount of demos available on the internet. To create a demo from scratch requires complex skills in C++. So I did another thorough research and come across CCV (Community Core Vision). An open source software dedicated for multitouch technology. It has multiple demos that can be tested. And it support flash demos.

However, the while trying out the software, I find that it is difficult to import flash demos into CCV. I try following the steps by steps guide but fail.I look into the problem on the internet, browsing into forum and discover TUIO mouse driver that will incoperate into CVV for better mouse control. Most flash demos mention TUIO and maybe that would solve the problem.

Below are examples of flash for multi-touch.








Installing CCV

Before installing CCV, user need to follow the step by step guide to ensure smooth installation. Link. I follow the guide but still fail to run CVV. This message keep popping up.
“The application failed to initialize properly (0xc0150002)”

So I browse into Multi-touch forum and discover that Microsoft Visual C++ 2008 Redistributable Package (x64) that I install does not work with CCV.I then have to switch to Microsoft Visual C++ 2008 Redistributable Package (x86)). It works and I was able to run CCV without any glitch.
