Backtracc - reminds you of forgotten valuables when you leave rideshare vehicles because forgetting items in strangers' cars isn't fun #lightning_hackathon

Search up ‘lost items’ on r/uber, and you’ll find countless stories of people losing valuable possessions to Uber rides and other similar services.

Our project helps Uber drivers and riders by notifying both parties when items are left behind after their rides.

Once a ride is completed, which we know when riders are no longer detected, we use a camera to check for any items left behind. The image will be sent to Sambanova’s API using Llama-3.2-11B-Vision-Instruct models to detect and classify the forgotten items like what is it and the color of it. If items are left behind, our system will keep a log of it and send a notification instantly to the rider and driver as soon as possible.

@duy.pham Welcome to the community and thank you for submitting.

My mother has always told me I would lose my head if it were not attached . This type of app would have saved me so much grief and money over the years.

Kudos !
