As tracking and surveillance solutions are proposed to guide us through the current crisis, we enact another control system through the passive observation of our neighbors. Are they a threat, or essential to retaining our feeling of humanness? We notice our heightened sense of interdependence. Vibe Check appropriates common surveillance tools including face recognition and expression analysis to catalog the emotional effect exhibition visitors have on one another. Some are identified as evoking expressions of happiness, disgust, sadness, surprise, or boredom. Upon entering the exhibition, visitors are playfully alerted to who these people are, and as they leave, they may find they’ve earned this distinction themselves.

Commissioned by HeK and MU for the exhibition Real Feelings.

Follow the readme.md in each folder:

1. database/
2. app/
3. face/
4. automate/

• GPUs should be busy: run nvidia-smi
• Services should be running: cd automate && ./status

• Cameras should be sending data (active) cd rpi && ./cameras status

Install XBindKeys:

sudo apt-get install xbindkeys xbindkeys-config
xbindkeys --defaults > ~/.xbindkeysrc
xbindkeys-config

Add an action for control+shift + q pointing to:

bash /home/vibecheck/Documents/vibe-check/automate/killall-chrome.sh

And for control+shift + c pointing to:

bash /home/vibecheck/Documents/vibe-check/automate/open-chrome.sh

Set the machine to automatically reboot daily at 6am:

sudo crontab -e

Add the following line:

0 6   *   *   *    /sbin/shutdown -r +5

And then using "Startup Application Preferences", add the open-chrome.sh to run on startup.

To clear the crash cache run:

sudo rm /var/crash/*

Use x0vncserver. Run x0vncserver -passwordfile ~/.vnc/passwd -display :0 remotely and ssh -N -L 5901:localhost:5900 <hostname> locally then Screen Share to localhost:5901.

Two possibilities:

1. The native Ubuntu monitor configuration in ~/.config/monitors.xml is overriding the /etc/X11/xorg.conf generated by nvidia-settings. Go into the native Ubuntu "Displays" preferences panel and rotate the screens there.
2. Make sure to run nvidia-settings from the command line using sudo. Otherwise the xorg.conf will not be saved correctly.

This might be because pip is waiting for the keyring to be unlocked. Add this to ~/.profile:

export PYTHON_KEYRING_BACKEND=keyring.backends.null.Keyring

Check the Chrome terminal with ctrl-shift-J (outside kiosk mode). Make sure there is a data.json and images/ files.
