Timed trigger with chops

Beginners

Hello, Brains Trust!

I’m working on a project where I want to trigger an event (activate a TOP network) when a person’s eyes are closed for a continuous 3-second duration. I already have a data stream where 1 represents eyes closed and 0 represents eyes open.

I’m having a bit of trouble figuring out how to set this up using Timer or Trigger CHOPs, or if these are even the right approach for this?

I’ve attached a screenshot showing how I’m selecting the data—I’m using the Mediapipe plugin for this.

What would be the best approach following the logic operator?

Thanks in advance for any help!

Hi @h2ho,

welcome to the forum.
in theory you already have everything you need. Question now is what do you mean by activating a TOP network? Can you describe a bit what you want to do and if possible share a network that shows your progress and illustrates your question?

A good general starting point to understand how channels can be used to control parameters and more, can be found in our curriculum at learn.derivative.ca - especially check out the videos on working with signals:
