PROJECT COVER2026
“How might an invisible bodily change become a quiet, legible pause?”
Overview
CloudSense explores how people can notice emotional change before it becomes noise. A cloud-shaped device gathers heart rate, electrodermal activity and fingertip temperature through touch, then pairs the signals with a reflective interface. The project was deliberately narrowed from ‘judging emotion’ to supporting personal recording and reflection.
My contribution
Built the Arduino Nano and Python acquisition flow, connected three sensor types, designed the web interface, modelled the enclosure and iterated the 3D-printed physical prototype.

PROJECT COVER2026
“Can the body warn the skier before excitement hides fatigue?”
Overview
VIGIL is a thigh-worn fatigue-awareness system for recreational skiers. It combines surface electromyography, a short personal baseline and RMS / MDF / MNF features with three levels of visual and haptic feedback, helping a skier decide when to slow down or rest without interrupting the experience.
My contribution
Interviewed two skiers, narrowed the problem from posture coaching to fatigue awareness, then completed wiring and soldering, live signal capture and filtering, electronics enclosure modelling, wearable prototyping and the end-to-end web display flow.

PROJECT COVER2026
“How can a boundary remain legible to herders and become permeable to wildlife?”
Overview
Common Ground responds to the conflict between pasture fencing and Przewalski’s gazelle movement around Qinghai Lake. Instead of removing the fence, the proposal embeds two or three linked gate modules into the existing boundary and connects passage configuration, inspection, operation and maintenance compensation into one accountable system.
My contribution
Mapped stakeholder needs and maintenance responsibility, developed the conditional passage logic, and joined the construction of a near full-scale functional fence prototype, iterating timber dimensions, joints and locking positions.

Co-creation
CO-CREATION · BUILDING WITH AI
Starting with a personal need
Two local prototypes shaped by everyday needs and developed with AI. Small tools to use, question and keep improving.
Co-creation / AI image canvas · Local prototype2026 · DEMO
01 / GROWTH
Growth
Keep images and their iterations together on one canvas.
After rounds of generating, downloading and editing, I often lost track of where an image began. This canvas keeps the evolving process visible alongside its results.

Device presentation · AI composite; actual interface below
01 / INTERFACE & KEY PATH
Let an image grow through iteration
Image selection, prompts and version management sit together, reducing the need to search across folders and conversations.
01
Keep it in view
Images become nodes you can move, zoom and rearrange.
02
Continue from this image
Select an image and describe a change alongside it.
03
Keep the lineage
Connect subsequent versions as branches so each choice has a traceable origin.

02 / NOW & NEXT

Working with AI
I defined the need to preserve visual iterations, shaped the canvas workflow and provided feedback through use, working with AI on the interface, integration and iteration.
Current scope
A local tool for organizing images and exploring branching workflows. The example shown here demonstrates importing and editing, rather than claiming a generated result.
Next iterations
Next: make large image collections easier to find and review, then explore use across devices. Public release follows sustained personal use.
Open-source foundation: adapted from infinite-canvas ↗ (AGPL-3.0). Logo and device presentation created with AI.

Posture Atlas
Connect understanding, everyday action and long-term records.
Personal posture management asks for ongoing observation. I wanted one place for learning, everyday action and records that could evolve with my own habits.

Relationship map · A focused thread
01 / INTERFACE & KEY PATH
From seeing relationships to keeping a record
The map organizes questions; actions and records support everyday use. Start with a focus, then expand the context.

Enter the relationship map through a topic of personal interest.
02
Reduce the noise
Focus on related nodes and explore the map step by step.

Continue with an exercise library, check-ins and a record over time.

Working with AI
I began with my own posture-management needs, chose what to record and revisit, then worked with AI to connect the map, exercise library and daily journal.
Current scope
A personal posture-journaling prototype. Relationships and exercise content still require professional review; corrective outcomes have not been validated, and it does not provide diagnosis.
Next iterations
Improve long-term records and personalization first, then explore independent user profiles, cross-device use and an app. These remain future directions.

“Can a toaster explain what it is doing before the bread is already burnt?”
Design intent
Conventional pop-up toasters hide the cooking state inside a narrow slot and force different bread forms into one interaction. This concept reworks the appliance around an observable conveyor, a transparent cover and a small set of legible controls.
My contribution
Identified usability issues, translated design-psychology principles into the operating sequence, explored the form through sketches, and completed the product model and renders.

Let the process be seen
The transparent cover turns browning from a hidden state into continuous feedback. Bread enters from one side and leaves from the other, so direction, progress and result share one natural spatial mapping.

Reduce the cost of a small mistake
An open feed path accepts slices, thicker bread and small pastries without a fixed slot. A single control reduces decision load, while the pull-out tray makes crumbs visible and cleaning direct.

“How can regional character feel specific without becoming heavy or nostalgic?”
Design intent
The project reframes a regional health product for younger daily use. Instead of relying on dense claims or familiar gift-box conventions, it uses a flower-like folding structure, botanical linework and a restrained cream–olive palette.
My contribution
Completed product research, positioning, visual language, information hierarchy and the structural dieline, then produced a printed packaging sample.

Page Twentyfour
An independent bookstore for urban young adults, bringing books, coffee and exhibitions into one cultural space.
The name begins with a reading-inspired idea: page 24 is where a story starts to unfold. The bookstore is imagined as an unexpected entry into a plot, where visitors discover new interests through books, coffee and exhibitions. In response to online reading and increasingly similar physical bookstores, the project brings brand philosophy, visual identity and visitor experience into a shared identity.
The design ambition centres on space and environment, supported by wayfinding, communications, stationery, staff uniforms and everyday objects. The following identity, application and interface work presents the available parts of this system.
My contribution
Co-developed cup and wrapping-paper applications, and independently completed the tote bag, membership card and 28-page website interface. Selected identity assets, objects and screens show how the visual system works across different touchpoints.
Reading, coffee, exhibitions, events and about form the website’s five entrances. A desktop navigation becomes a mobile menu. Paper tones, the bear mark and shared components carry the bookstore identity through every path.

Visual identity
A bear, a number, an identity
The number 24 and a bear form one recognisable, approachable mark. Ochre, brown and paper tones carry the reading-room palette, with reading-lamp yellow as an accent. The mark appears on its own or becomes a repeating pattern for different applications.

An identity to carry
The tote leaves space around the mark while keeping its sides and opening simple. Capacity, handling and identity come together in an everyday object. The membership card follows the same graphic language, with the mark on the front and membership details on the reverse.
