Inspiration

"Hey, hey, hey Just think, while you've been gettin' down and out about the liars And the dirty, dirty cheats of the world You could've been gettin' down to this sick beat"

Taylor Swift

What it does

Implements Lens Studio's hand tracking capabilities to create a gesture-based DJ beat-making AR Snapchat lens

How we built it

Uses Lens Studio’s Hand Tracking module to detect and follow finger positions in real time
JavaScript scripts map gestures (swipes, flicks, pinches) to DJ actions like triggering beats, adjusting volume, and activating scratch mode
AudioComponent is programmatically started and modulated based on detected gestures
Rave-inspired visual effects (VFX) are created using shaders and particle systems
Core interactions use event-driven logic for responsive performance and a seamless AR experience

Challenges we ran into

Iterating on an MVP while avoiding scope creep
Not getting carried away with Lens Studio's host of features

Accomplishments that we're proud of

Implementing the "scratch mode" feature, allowing you to seamlessly control audio level with the flick of a finger
Scripting VFX that perfectly balance out audio to create a full immersive experience
