Prototyping
Woodshop Prototype
A portable bag hook that improves safety and organization in shared spaces such as classrooms and cafés. Designed for users of all ages, it lifts bags off the floor and keeps them accessible beneath desks or tables. The bag’s weight anchors the hook in place, while a rubberized contact surface increases friction for added stability and reliability.
Bagugu
Extended Reality (Unity, Meta Quest 2)
A VR experience designed for long-term hospital patients, allowing them to mentally step outside their hospital room and engage with simulated public spaces. Through controller-based interaction and optional physical movement, users can experience everyday social scenarios populated by NPCs that mimic spontaneous human behavior, offering a sense of presence and social connection during extended hospital stays.
Sweet Valley
Electronics Prototype (Arduino Uno, Arduino IDE, Autodesk Maya)
An interactive system designed to help users decide what to wear before leaving home. Installed in an apartment entryway, it uses temperature and humidity data to recommend appropriate clothing or accessories. With a single button press, users receive visual guidance through LED indicators, reducing decision fatigue and helping them prepare for changing weather conditions.
FitCheck
Electronics Prototype (Arduino Uno, Arduino IDE, Autodesk Maya)
A smart spice rack designed to encourage organization and mindful kitchen resets after cooking. By detecting when spice jars are returned to their designated spots, the system provides gentle visual feedback through a green light, reinforcing order and reducing clutter. The rack helps prevent misplaced spices while making everyday kitchen organization more intuitive and satisfying.
Spice Rack
A fictional object that borrows the idea of a tooth fairy, except the surprises consist of a good night’s sleep and a pleasant dream for the user when a star is placed under a pillow. Inspired by Diptyque perfume bottles and sleep-inducing supplements.
DreamFairy
Lasercutting prototype
A key-holder that powers user’s home when a key pulls the switch down with its weight.
HangON

Instruction Set for Strangers
A speculative, participatory auction set in the year 2100 that critiques the privatization of healthcare by turning survival into a competitive marketplace. Participants embodied personas and bid on essential medical resources, exposing how access, scarcity, and narrative influence who receives care.
A research-driven UX experiment that studies how users respond to scarcity and unequal access through personas, bidding mechanics, and environmental cues.
The Great American Health Auction
How can we increase interpersonal interaction at the T-stop, where everyone is only focused on getting to their destination?
When strangers try to solve the word puzzle together, it gives them a reason to chat and share a moment. By conducting multiple rounds of user testing, our team was successful in getting a high number of interactions at a utilitarian location.
