Inspiration
Some of the challenges given to us by Wakefern Food Corp at HackRU are to optimize operations and harness AI in grocery. With social skills falling after the pandemic, we came up with an idea to train cashiers with AI!
What it does
The cashier simulator game shows how it is like to be a cashier. You have to multitask and manage two tasks, scanning items, and responding to customers. Your goal is to earn as many points as possible before running out of time.
How we used AI
We used Gemini to simulate random customer behaviors and to respond to the user in a realistic way. After all their items are scanned, Gemini is asked to rate the user's customer service performance, and that determines how many points they receive for that portion of the game.
Accomplishments that we're proud of
Our team has never used an AI API before, and we learned to sent prompts very quickly for this project!
