Overview of Overcooked

Thank you for participating in this user study! You will be playing a web-based game of Overcooked, a 2-player cooking simulator. Your goal is to try to serve as many dishes of onion soup as possible within a 40 second time limit. Below is an annotated diagram of the environment:

Movement and Interactions

You can move up, down, left, and right using the arrow keys, and interact with objects using the spacebar.

You can interact with objects by facing them and pressing spacebar. Here are some examples:

• You can pick up onions by facing the onion area and pressing spacebar.
• You can pick up a plate by facing the plate area and pressing spacebar.
• If you are holding an item, are facing an empty counter, and press spacebar, you put that item on the counter.
• If you are holding an onion, are facing a pot that is not full, and press spacebar, you will put the onion in the pot.

As a reminder, you must face the object you are trying to interact with.

Note that as you and your partner are moving around the kitchen you cannot occupy the same location, so you have to coordinate the navigation with your partner.

Cooking

To make soup, place 3 onions in the pot and the timer will start counting up from 0. When the timer reaches 20, the soup is fully cooked. You must carry a plate to the pot and interact with the pot to fill the plate. Then, you can carry the plate back to the serving counter, and you will get 20 points.

Your Task

You will be playing the Overcooked game in two different layouts: Cramped Room and Coordination Ring.

For each environment, you will first be given the chance to understand the layout by playing 2 games with no active AI partner. After this, you will play each of 4 trained AI's in the "Algo" dropdown twice (playing both games for a single Algo back-to-back) in the order of the dropdown. Each time you finish 2 games with an AI, you should fill out this Google form to provide feedback on the AI partner.

After you have played with each agent twice on the Cramped Room layout, you will do the same process for the Coordination Ring layout.

Here is an example interface:

The text below the gameplay reminds you to fill out the Google form and what configurations you have already finished playing. The bold line tells you what configuration to play. There are 2 layouts, 5 algos to choose from (including the "NO AI"), and you will play in each configuration twice, so in total you will play 20 rounds of Overcooked, each of which are 40 seconds long.

For all configurations, your goal will be to get as high of a score as possible by serving the most soup in the 40 second time limit.

Unfortunately there will be lag due to network latency. That is to be expected.

Good luck and have fun!
