Hi folks,

I am trying to accomplish the following:

I get a constant value stream out of FaceOSC with tacking data of e.g. mouth width.

What I want to do is to measure if the mouth is being opened or closed within the process of doing so.

The output are values from 1-10 per frame at a framerate/s of 60.

I tried to take averages of the values of say half a second, put them into {pipe} and use simple > < comparison with the real time data and the pipe-data. The problem is, that the output always is compared 2 times (the moment the current value comes in and the moment, pipe gives an output).

Can somebody give me a hint on how to do that in a more beautiful way?

Thank you so much in advance! The moment of frustration is nigh

Best regards,

Janek

Hi Janek,

It would be helpful if we could see your patch, but it sounds like you have an evaluation order issue. Remember that the left inlet on objects is usually hot, meaning that it outputs a value whenever it receives an input. The right hand inlet is usually cold, which means it stores it instead of outputting.

I've attached a nice way to do integration, just set the number of points to integrate over as the first argument when instantiating it.

Cheers,
Joe
