You’re at a very busy restaurant, and your drink cup is empty while eating the spiciest dish of your life. You haven’t seen your waiter in a long time, as they are scrambling all over the place with new customers. You’re getting angry, and have no way to get the waiter’s attention. You end up leaving the restaurant and giving them a bad review.

The goal of our project was to design a system of wirelessly communicating electronic drink coasters. Each coaster keeps track of whether the customer's cup is empty or full, and sends that data back to the server's display. We believe this automatic clever coaster system will make restaurant staff more efficient and overall improve the customer experience.
