Use Your Melon
A gesture-controlled installation challenging Georgia Aquarium guests to a game of echolocation charades

summary
The Georgia Aquarium’s Dolphin Coast opens onto a pre-show atrium where guests wait — often the better part of an hour — in front of blank walls and a small tank view. For our Georgia Tech master’s thesis, we asked how that space could be better leveraged to teach people about the animals they were about to meet.
Use Your Melon turns the wait into a game of charades. Guests strike a pose to mimic a sea creature, and a digital dolphin echolocates to identify them and explain their relationship in the wild.
The walls were pretty blank… it would’ve been nice to have a little more to do

my role
I pitched in on the guest research, sitting in on the observations and interviews and helping sort it all onto the affinity map.
Once we landed on a concept for a gesture-based installation, I designed the interactions and the general flow, then built technical spikes to test the capabilities of our hardware. From there I integrated all of the UI into a working pilot in Unity, all from the comfort of my apartment during lockdown.
how to play
step right up
Approach the screen and a dolphin companion greets you beside a bubblized version of yourself.
strike a pose
Find the hidden gesture for one of six creatures and the dolphin starts echolocating to identify you.
transform
Hold the pose, burst into bubbles, and learn how that creature lives alongside dolphins in the wild.

process
guest research
We interviewed 14 participants across guests, floor staff, and managers, then processed their feedback on an affinity map.
participatory design
Five aquarium stakeholders helped brainstorm interaction concepts in a group session.
gestural study
We asked some friends to mimic different sea creatures on camera, and six came through consistently enough to base the game on.
technical spikes
I built quick prototypes to test our core interactions against Microsoft Kinect’s gesture recognition engine.


outcomes
- — Completed the work as a Georgia Tech MS-HCI master’s thesis advised by Dr. Carrie Bruce
- — Partnered with the Georgia Aquarium to design for their Dolphin Coast pre-show atrium
- — Shipped a feature-complete Unity and Kinect demo recognizing six creature poses
- — Evaluated remotely with four aquarium stakeholders and five physical-interaction experts; 12 of 13 heuristics averaged only cosmetic or minor issues
