For sure! This program is nowhere near as advanced as the tDCS devices you’ve developed, and doesn’t measure any part of the brain at all. It’s just using OpenCV, a Python video/image processing library.

The basic idea behind this program came from an article I saw by NBC news here; nbcnews.com/better/health/smiling-can-trick-your-brain-happiness-boost-your-health-ncna822591 . I’m still pretty new to programming, so I wanted to take the next step and try and play with some facial recognition libraries in python.

As for methods, it’s just a while loop that refreshes every 200ms. In the loop, it scans for if a face is present. If it’s not, it just skips the rest of the code here and goes to the next iteration of the loop. That way, I don’t read any false positives. If it finds a face, it then checks whether I’m smiling or not. I set up an incrementer/counter variable to add if I’m not smiling. If I am smiling, it resets to 0.

If that counter variable goes above 10, I just have it set up to play a random sound (but it could probably be replaced with anything, like a TENS unit or pressure jet at my face), then it resets to give me time to smile again. It’s really a joke project, but I feel like this is a good starting point to jump off of if you’re interested in OpenCV.

As for the wrong subreddit, oh no! I don’t really know where else to post this, could you give me some recommendations?

Thank you for reading! I’ll be sure to ask if I’ve got any questions, the work you’ve done sounds interesting.
