TUIO and Touchlib weak robustness
Nov 29th, 2008, 6:46pm  
Hi there,
I'm doing a project with processing, the tuio library and Touchlib right now in order to track bright blobs. The program will be used for a theater performance and must run around 70 minutes.

In general it works fine, but now and then processing just stops handling the tuio events, even without showing errors. When I then restart processing and keep Touchlib running it works again. That's why I don't think the problem is not at the Touchlib side.

For the performance it is really desirable that the program is stable. Has anyone experiences with this, has observed the same problems, or has found a solution to make it more robust?

I am using Touchlib tbeta and Processing 0157 by the way. (Don't want to switch to Processing 1 right now, since the first night will be pretty soon...)

Regards,
Grit.

Hey guys,

I found out, what my problem was and think it can be interesting for some others:

I have a quite complex application and during the performance I trigger some "chapter"-setups, where variables are set. Since the tuio handlers run all the time it happened now and then, that they tried to access some data that where not "ready to use, yet", which coursed conflicts.

I solved this problem by disconnecting the port with:

tuioClient.dispose();

before I do a chapter-setup. After the chapter is ready to run I create a new TuioClient:

tuioClient = new TuioClient(this);

This seems to work very well.
However I would like to know, if this way is recommended or if there is a more appropriate approach.

Thanks,
Grit.
