Overcooked Demo

This fork of Human-compatible AI's Overcooked Demo has been modified for use in experiments on importance of eye gaze in human-AI collaboration, carried out at King's College London in 2022 by P. Tisnikar and L. Wachowiak. The custom environment contains 2 levels, forced_coordination and counter_circuit, with modified graphics to hide tomatoes in a cupboard in order to confuse the players. Added functionality includes integration with eye-tracking software.

The results of this study are available and discussed here. If using this specific environment, please cite as:

The server uses a custom branch of the original overcooked-ai game environment that can be found here. This environment contains the modified layouts, player starting positions, and recipes used in the experiments, along with suspension of cooking unless all 3 ingredients are present in the pot.

It is recommended that any new adaptation of these environments originates from the source repositories which can be found below: Overcooked Demo Overcooked game logic Human-aware RL

Installation (From HCAI)

Building the server image requires Docker

Usage

The server can be deployed locally using the driver script included in the repo. To run the production server, use the command

./up.sh production

In order to build and run the development server, which includes helpful debugging logs, run

./up.sh

After running one of the above commands, navigate to http://localhost

In order to kill the production server, run

./down.sh
