Procedure report:

1 - To use motion detection in Pd from our webcam, we need to use the "gem" library.

2- "Pd vainilla" doesn't install "Gem" by default. We need to download it and drag the folder in Users>Library>Pd (if there isn't, we create one)

3- Specify the "path" to this folder on Pd preferences.

4- Oops, the webcam is still not detected! :@

5- Apparently, Gem doesn't work with newer versions of Mac OS in "Pd Vainilla"

6- Let's try downloading "Pd - Extended", checking the path, etc.

7- Now it works! webcam is detected in Pd, success.

8- However, the log sends me errors of files that couldn't be loaded. Weird.

9- I keep on experimenting with the patch also using different tools from the gem library; pix_color/grey and other filters, rectangle shapes and positioning, pix_blob 4 using Osc to create sounds out of motion detection, etc.

10- I try to import audio to "Pd-extended" using different methods: "openpanel" by uploading everytime the audio file and "open" from path. ...but Pd cannot open the audio file! :@

11 - I need to Download XQuarz so my system's library will be automatically updated.

12- Now we can import and listen to audio files! :)

13- Another Issue; the audio file plays far too fast

14- Check out audio file: - in preview: (16 bits per sample) - in Audacity: Sample Rate Format (32-bit float) - Default setting in Pd: Sample Rate: 41000

Which settings do work: 24000 Sample Rate

- How can a body be represented into a score?

- "Biovision Hierarchy" = file format - motion detection.

- Femke Snelting reads the Biovision Hierarchy Standard

- Systems of notations and coreography - Johanna's thesis in the wiki

- There are blocks of different technical properties that doesn't really connect to each other, which it seems arbitrary. In order to clarify and strengthen the concept, they need to run sepparately;

1 - on one side there is * motion capture * using different tools/software like "Kinect", "Synapse" app, "Max MSP", "Ableton", etc...

* This one could be more interestingly explored separately

2 - on the other hand, there is data / information reading (e.g. countries, number of refugees arrived / dead / ... )

* This can be further developed and simplified. * However, motion capture using Pd and an ordinary webcam to make audio effects could be efficiently linked.
