Project DeLTA

Decentralized Land Transportation Assistant

Delta is a land transportation communication system designed for safety, convenience, and accessibility.

✨ Features

🕊️ Decentralized Communication

Communication is done via a peer-to-peer network without a need for a central server. Peers can call each other, alert each other, and share their location and speed.

💥 Crash Detection

Crash detection is done by monitoring the accelerometer. When a crash is detected and confirmed by the user, an alert is sent to all peers.

🗣️ Hands-Free Operation

Say delta to activate the voice assistant, then say any of the following commands.

General Commands	Description
call [peer name]	Call a peer.
alert [sos / hazard / yielding]	Alert all peers.
find [place type]	Find and show a place.

Active Call Commands	Description
accept	Accept incoming call.
decline	Decline incoming call.
cancel	Cancel outgoing call.
end	End ongoing call.

Places View Commands	Description
previous	Show previous place.
next	Show next place.
exit	Exit places view.

📍 Nearby Places

Nearby places are shown on the map. Click on a place to show a QR code for more information.

🎨 Customization

The user can set their display icon as well as set communication preferences.

🖊️ Planned Features

🏢 V2I (Vehicle to Infrastructure) Communication

Vehicles can communicate with infrastructure like traffic lights, road signs, and toll gates.

🚨 Driver Alertness Detection

Driver alertness is monitored by sensors, such as a camera. When the driver is detected to be drowsy, a warning is shown.

🏗️ Building and Running

1. Set up a toolbox container.
   • Run, toolbox create --image quay.io/toolbx-images/debian-toolbox:12
2. Set up Rust via rustup.
   • Optionally, install rust-analyzer via rustup component add rust-analyzer.
3. Install the required dependencies.

sudo apt install libgtk-4-dev libadwaita-1-dev libshumate-dev libgstreamer1.0-dev gstreamer1.0-plugins-good libspeechd-dev speech-dispatcher cmake clang gpsd gpsd-clients

4. Set up text-to-speech (TTS).
   1. Uncomment the required locale from /etc/locale.gen.
   2. Install locales via apt and run /usr/sbin/locale-gen.
5. Set up speech-to-text (STT).

git clone https://github.com/ggerganov/whisper.cpp.git
