Spinal

Spinal helps you to “hear” your spine condition. This wearable technology serves as an amplifying interface for the spine. Your spine allows you to move and feel due to its major role in the nervous system. This project aims to raise awareness about your spine by creating a shape-shifting interface of communication which can adapt to any spine. In order to prevent an ongoing deterioration, Spinal will help your spine to manifest its condition using a real-time 3D OpenGL visualisation. This wearable wireless piece can serve both medical and artistic purposes.

Roadmap

• Visualization
• Serial communication
• Real-time eulier angles
• Bluetooth integration
• Calibrations
• Spine reconstruction
  • Artificial using Catmull-Rom Spline
  • Real based on mathematical model
• User interactions

Real-time OpenGL visualization

Controls

scroll      z-zoom
arrows      rotate

w           move forward
s           move backward
a           move left
d           move right

l           display lines
p           display points

g           generate spine

Setup

Tested on Arch Linux.

Dependencies: glew glm glfw-x11 mesa-demos

Compile: cd src/dots/; make arch

Run it: ./run.sh <serial-port>

USB

Logic: Spinal Serial over USB <-> Dots

./run /dev/ttyUSB0

Bluetooth

Note: quickly test Spinal over bluetooth with an Android using S2 Terminal for Bluetooth application.

Dots:

Logic: Spinal Serial over Bluetooth Mate <-> Laptop Bluetooth adapter <-> Dots

Install the dependencies:

pacman -S bluez

In recent bluez-utils versions rfcomm is missing so we downgrade it:

pacman -S libs/bluez-utils-5.31-1-x86_64.pkg.tar.xz

Activate the module:

modprobe btusb

Add user to group and logout for changes to take effect:

sudo gpasswd --add <user> lp

Start the service:

systemctl start bluetooth

Pair the device using bluetoothctl where ````` its mac address:

power on
agent on
scan on
... wait ...
scan off
pair <dev>

We are expecting serial so we can't simply connect to it. We have to emulate serial over bluetooth by binding the paired device to a serial port:

rfcomm bind 0 <dev>

Finally, run the visualization:

./run /dev/rfcomm0

To reset everything:

# bash
rfcomm release 0

# bluetoothctl
remove <dev>
power off
