Problem & Opportunity
(01)
This project examines how non-visual inputs and outputs—such as movement, distance, and scent—can create more intuitive and emotionally resonant interactions. Instead of relying on screens, the experience responds directly to human presence in physical space.
/
Solution
(02)
I designed a circular portal that responds to a visitor’s distance and movement. As people approach, the system releases curated scents while real-time visuals evolve—turning invisible sensory input into a tangible, emotional interaction

Design Process
(03)
I designed a circular portal that responds to a visitor’s distance and movement while inviting intentional participation. Instead of automatically releasing scent, the portal encourages users to lean in and actively engage, turning proximity and presence into a deliberate, multisensory moment paired with evolving real-time visuals.
Through iterative prototyping, I explored how proximity, diffusion, and projection could visualize scent. I sketched multiple interaction flows from hand-activated triggers to ambient sensing systems to capture the moment scent enters space. Each design decision balanced technical logic (sensor response timing, projection mapping precision) with emotional rhythm (soft gradients, slow animation, ambient tone).

Making Process
(05)
Hardware: Arduino Uno R4, ultrasonic sensor, capacitive touch sensor
Software: TouchDesigner for real-time projection mapping and light diffusion
Fragrance: Custom five-note blend representing Los Angeles (Birch Tar, Benzyl Salicylate, Orris, Neroli, and an ambient base note)
Physical Form & Fabrication: Hand-shaped 20 lb foam sculpted into a circular frame, coated and painted to create a smooth, light-reflective surface. Layered translucent fabric wraps the structure, integrated with a scent-diffusion module.

Interaction Flow
(06)
Opener — The portal invites exploration through form and ambient cues.
Approach — Proximity activates responsive light and sound.
Sniff — Scent is experienced intentionally through user engagement.
Transform — Visuals shift to reflect the fluid nature of memory.
