+I was not so happy with the pixel manipulation. Online, I found an effect that I really like. It’s used for motion tracking. If the object is still, you don't see it. If it moves, you can hardly see the outline. If it moves faster, you can see more and more.

-What I am imagining right now, but don’t know where to start is the following: The visitor is coming closer to the screen, seeing itself inside the webcam.

The pixels of the human stretches to the rhythm of the pulse.

			'''04.06.2021''' manipulate webcam image by pixels

			Please find here the patch: [[:File:210604_Project.maxpat]]

			I can't figure out how to create a new image / video from the edited cellblock (the edited pixels).
			Do you have a tutorial or references for that? I am wondering if a command which manipulates the whole image - not individual pixels - would be interesting. Probably that's why you recommended jit.gl.pix, but I can't make it work.

'''03.06.2021''' sensor arrived / try and error

I connected the pulse sensor to Max and had some troubles on my way there.

[[File:Screenshot 2021-06-03 at 11.16.31.png|400px]]

As the sensor is sensitive to light, I came up with the idea to put it inside a box. I seems to make a difference, but I am not sure.

I used similar objects from the "sensing physical parameters" patch and an Arduino code I found online.

[[File:Pulse Sensor to Max_2.jpg|400px]]

I have no clue how to connect the input from the sensor to the webcam image. I am searching online, but I haven’t found good references / tutorial how to distort a live image with specific data input. I would be very happy for any hint.
During the research, I found the method of using the webcam as the tool to measure your heart rate. I think this would be way more interesting!! [https://hackaday.com/2020/12/25/webcam-heart-rate-monitor-brings-photoplethysmography-to-your-pc/] Using the webcam as the sensor and for creating the visuals as well.

What I am imagining right now, but don’t know where to start is the following: The visitor is coming closer to the screen, seeing itself inside the webcam. The pulse gets identified by the webcam and the human is recognized as well, (ideally turns red-ish; opacitiy 50%; maybe by using the cellblock object?) The pixels of the human stretches to the rhythm of the pulse.
