NeuroEmo is an interactive installation that transforms human emotion into a physical, multisensory experience. Using real-time camera input and AI emotion recognition, the system maps a person’s current emotional state—such as joy, sadness, or anger—onto a 3D brain-shaped model, where neural pathways and emotional circuits are visualized through dynamic lights, colors, and animated behaviors. Grounded in neuroscience, NeuroEmo narrates how different emotions are processed in the brain, from dopamine–driven “roller coasters of happiness” to hippocampal “storms of sadness” and amygdala “volcanic anger.” These internal neural processes are made visible, tangible, and playful through storytelling and sensory feedback, including mechanical gestures (such as dispensing candy for comfort or releasing bubbles in celebration) that reinforce brain–emotion interactions in a whimsical way. By externalizing the “invisible storms” of our inner emotional world, NeuroEmo helps audiences better understand their feelings, giving children and adults a novel way to see, feel, and learn how the brain constructs emotion—making neuroscience approachable, relatable, and delightfully human.
