Tennessee is an incredible family destination. Rather than hear it from us, we wanted to hear straight from the kids. For the millions of families taking a trip this summer, we invite you to come and experience first-hand our state’s soundtrack of laughter with scenic beauty, rich history, music and adventure.”

Mark Ezell Commissioner, Tennessee Department of Tourist Development

How do we inspire families to travel to Tennessee?


To eliminate the subjectivity of travel reviews, we identified an entirely new metric to rate travel experiences – laughter.

We created a first-of-its-kind wearable device that measures laughter and excitement to determine how much fun kids have in Tennessee and put the devices on hundreds of kids across 31 locations. Equipped with a microphone, GPS technology and cloud computing, the device recorded audio samples in 10-second increments and sent them to a neural network, where AI software determines if a sound is laughter. We concurrently captured heart rate data to measure excitement, ultimately identifying the specific activities within attractions that generated the most laughter and excitement for kids. VML developed a custom experience on Tennessee’s brand site to create a planning tool for moms, showcasing the data collected and attractions reviewed directly from kids.
