AI Conversation 5

Gesture Control of the hall

As we will be using a Raspberry Pi 5 with an AI HAT and an EL Wire HAT, it can use gestures to control the EL Wire lighting. The Arduino 33 BLE Sense can also use gestures to control the display and poetry.

That would complete the constellation beautifully, David. While I can’t directly generate or retrieve media files like JWildfire images or Sonic Pi audio from your installation, I can absolutely guide you in creating both—so your hall pulses with celestial light and music forged by motion and magnetism.

🌀 JWildfire: Fractal Cosmos Generation

To craft the visual language of your evolving universe, here’s how you can generate transcendent flame fractals using JWildfire:

🔧 Setup & Tools

• JWildfire Download
• Use the Flame Editor or Scripted Generator to create fractal variations
• Render high-res stills or 4K video loops for use in Processing or projection

🎨 Recommended Flame Styles by Gesture Class

You can assign color gradients to reflect tone:

• 🔵 Cool tones for calm/stillness
• 🔴 Warmer reds/oranges for energy spikes
• 🌈 Chromatic overlays for magnetic interference

If you’d like, I can also help write a JWildfire script to dynamically blend or evolve flames over time based on gesture categories.

🎶 Sonic Pi: Generative Celestial Soundscapes

For each gesture or planetary passage, trigger ambient music using Sonic Pi, mapping motion to harmonic, temporal, or spatial parameters.

🌠 Example: Sonic Pi Universe Engine

live_loop :orbital_theme do
  use_real_time
  gesture = sync "/osc*/gesture_triggered"
  
  case gesture[0]
  when "spiral_orbit"
    use_synth :dark_ambience
    play choose(scale(:e3, :phrygian)), release: 2, amp: 0.4
  when "flare_rise"
    use_synth :prophet
    play_pattern_timed scale(:a4, :lydian), 0.25, release: 1, amp: 0.6
  when "hover_listen"
    use_synth :hollow
    play :d3, release: 5, amp: 0.2
  when "aurora_turn"
    use_synth :blade
    play :g5, release: 2, cutoff: rrand(60, 100)
  end
  
  sleep 1
end

🎼 Recommended Synth Pairings

Adjust delay, reverb, and panning to reflect spatial field changes.

Would you like a script that links your gesture recognition pipeline directly to Sonic Pi using OSC, so the system becomes truly responsive in real time? Or a Processing module that overlays your rendered JWildfire fractals onto live poetry and field mapping?

Let’s keep sculpting this wonder. The universe is already listening.

Can you provide both the gesture recognition pipeline and the Processing module.

Absolutely, David. Let’s bring your celestial symphony to life—here’s how to build both the gesture recognition pipeline (Arduino + Raspberry Pi + Sonic Pi integration) and the Processing module (real-time visual + poetic response system, fed by fractal frames and motion data).

🧠 PART I: GESTURE RECOGNITION PIPELINE

Arduino Nano 33 BLE Sense + TinyML + Raspberry Pi + Sonic Pi

1. 🚀 Train a TinyML Model

Use Edge Impulse to train a gesture classifier using 9-axis motion data:

Example gesture labels:

• spiral_orbit
• flare_rise
• aurora_turn
• hover_listen

Once trained:

• Download the .zip Arduino library from Edge Impulse
• Include it in your Arduino sketch

2. 📡 Arduino Code (Serial Output to Pi)

#include <Arduino_LSM9DS1.h>
#include <Your_Model.h> // Edge Impulse model

void setup() {
  Serial.begin(9600);
  if (!IMU.begin()) {
    Serial.println("Failed to initialize IMU!");
    while (1);
  }
}

void loop() {
  float ax, ay, az, gx, gy, gz, mx, my, mz;
  if (IMU.accelerationAvailable() && IMU.gyroscopeAvailable() && IMU.magneticFieldAvailable()) {
    IMU.readAcceleration(ax, ay, az);
    IMU.readGyroscope(gx, gy, gz);
    IMU.readMagneticField(mx, my, mz);

    float input[] = { ax, ay, az, gx, gy, gz, mx, my, mz };
    ei_impulse_result_t result = run_classifier(input);

    for (size_t i = 0; i < EI_CLASSIFIER_LABEL_COUNT; i++) {
      if (result.classification[i].value > 0.8) {
        Serial.println(result.classification[i].label);
        break;
      }
    }
  }
  delay(200);
}

3. 🧭 Python on Raspberry Pi: Serial + OSC to Sonic Pi

import serial
from pythonosc.udp_client import SimpleUDPClient

arduino = serial.Serial('/dev/ttyACM0', 9600)
osc = SimpleUDPClient("127.0.0.1", 4559)

while True:
    label = arduino.readline().decode().strip()
    print("Gesture detected:", label)
    osc.send_message("/gesture_triggered", label)

🌌 PART II: PROCESSING MODULE

Visual + poetic response to gestures, supporting fractal frames + scrolling verse

1. 🎴 Folder Structure

/data
  /fractals
    spiral_orbit.mp4
    flare_rise.mp4
    ...
poetry.txt

2. 📜 poetry.txt Example

spiral_orbit: We twirl on invisible tides of time.
flare_rise: We sparked once—and the universe still remembers.
hover_listen: Stillness—where magnetism hums in dreams.

3. 🎨 Processing Sketch

import processing.video.*;
import java.util.HashMap;
import processing.serial.*;

Serial port;
Movie currentVideo;
HashMap<String, String> poetry = new HashMap<String, String>();
PFont font;
String currentGesture = "spiral_orbit";
String currentLine = "";

void setup() {
  size(1280, 720);
  font = createFont("Georgia-Bold", 24);
  textFont(font);
  loadPoetry("poetry.txt");

  port = new Serial(this, Serial.list()[0], 9600);
  port.bufferUntil('\n');
  loadVideo("spiral_orbit");
}

void draw() {
  background(0);
  if (currentVideo != null) {
    image(currentVideo, 0, 0, width, height);
  }

  // Scroll poetry
  fill(255);
  text(currentLine, 50, height - 60);
}

void serialEvent(Serial port) {
  String gesture = trim(port.readStringUntil('\n'));
  if (!gesture.equals(currentGesture)) {
    currentGesture = gesture;
    currentLine = poetry.getOrDefault(gesture, ""); 
    loadVideo(gesture);
  }
}

void movieEvent(Movie m) {
  m.read();
}

void loadVideo(String label) {
  if (currentVideo != null) currentVideo.stop();
  currentVideo = new Movie(this, "fractals/" + label + ".mp4");
  currentVideo.loop();
}

void loadPoetry(String filename) {
  String[] lines = loadStrings(filename);
  for (String line : lines) {
    String[] parts = split(line, ":");
    if (parts.length == 2) {
      poetry.put(trim(parts[0]), trim(parts[1]));
    }
  }
}

🌠 Additions & Enhancements

• 🔉 Add espeak TTS in Python to speak currentLine aloud when gesture updates
• 🌈 Use gesture intensity (e.g. acceleration magnitude) to modulate hue, brightness, or trail speed in Processing
• 🧩 Add OSC feedback from Processing to Sonic Pi to cue tonal shifts along with visuals

Would you like me to help design a planetary verse catalog, animate motion trails in Processing, or develop a companion control dashboard for live performances?
