Sentiers Aveugles (Blind Paths)

Final Year Project / POC of my 2nd Year at Gobelins - Paris.
Theme : The 5 Senses and the 4 Elements.


A defined area is subdivided in a (by default 3x3) grid, each subdivision then having a random sound mapped onto it.
The user's position in that space is calculated by weighting out the number of points in each subdivision, by depth and position on the X axis. The gyroscope allows for the app to take full advantage of the Web Audio Spatialization API.

1. Building the Kinect App:

cd ./kinect
cmake .
cmake --build .

2. Building and running the Electron app:

cd ../app
npm i
npm run start

You should then see (by default) 9 spheres in a grid, along with a Sphere Mesh. The red section of the latter represents the eyes of the user.

3. Setting up and Connecting the M5StickC-Plus:

You'll need the following libs :

Keep in mind you'll need to add the M5Stack boards to your board manager, by using the following link : Boards JSON

After uploading the firmware to the board, you'll need to connect it to the same WiFi network as the computer the apps run on.
To do this, install the BlueFruit Connect app: Android / iOS.

Then, connect to the M5Stick. It should be called "SentiersAveugles-Gyro-XX". You can now send your network info in that order (Check the M5Stick's screen for any error) :

  • SSID
  • PWD
  • Local IP Address of the computer (you can scan the QRCode on the electron app to get it)
  • OSC Port (default is 9419)

4. Calibration:

  • Press E on the Kinect App to calibrate the depth. This will allow the program to detect pixels that have changed depth (thus if something moved at that specific position), compared to a reference frame.
  • After ensuring the red section on the Sphere Mesh moves when rotating the gyroscope along the Z axis, click on the A button when the red section faces the left side. Then, strap the gyroscope onto the headphones, face the kinect, and press the A button again. You're now all set !

Additionnal Information

I'm using the M5StickC-Plus solely for the fact that it packs a gyroscope/accelerometer, WiFi, Bluetooth and a battery, without the need to plug anything else in. Since it's based off a widely used chip, the ESP32, and that I'm not using any specific chip reliant functionnality, it should be fairly easy to adapt.

Shortcuts

  • Kinect App
    • E : Calibration
    • O and P: Decrease / Increase Depth Threshold
    • W and S: Zoom in/out
    • V: Reset Calibration and deactivate OSC connection

    • A(Short-Press): Toggle OSC connection
    • A(Long-Press): Reset Conections (Both OSC and WiFi, Bluetooth will remain)
    • B(Long-Press): Turn ON/OFF
