Overview

During my first design hackathon, my partner and I designed a speculative tool that tracks something invisible in the human experience.

The Bloom — a wearable biosensor patch and companion app that detects and visualizes joy in real time, turning fleeting moments of happiness into something you can feel and record.

The Prompt

Design a speculative tool that tracks, measures or visualizes an aspect of human sensory experience..

The goal: not to remix what already exists, but to create something rooted in real human needs and meaningful wellness outcomes.

The Solution


A wearable biosensor patch and companion app that detects and visualizes joy in real time, turning fleeting moments of happiness into something you can feel and record.

Phase 1: Ideate

The idea should be fun & simple

With only 72 hours, the biggest risk was committing too early, or too late, and falling in love with the first idea.

I led rapid ideation across 6–7 distinct concepts, narrowed to 2 strong directions, and stress-tested each against the brief.

Our guiding principle: the idea had to be simple, intuitive, and emotionally engaging.


Brainstorming board, narrowing from 6 speculative concepts to 2 final directions!


The Concept

Inspired by bioluminescent organisms such as jellyfish and fireflies, that make internal chemical processes visible on their surface.

We asked: what if human emotional states worked the same way?


Science Grounding

Happiness is not abstract—it is biochemical.

Neurochemicals such as dopamine, oxytocin, serotonin, and endorphins (D.O.S.E.) signal moments of joy, often without conscious awareness.

We reframed happiness as → detectable, measurable, worth capturing


Phase 2: Research

Sensing System Design

I translated the concept into a feasible sensing pipeline:


INPUT: Biosensing

Continuously captures biochemical signals related to D.O.S.E.
(e.g., carbon-based microelectrodes, nano-biosensors)

PROCESSING: Signal Interpretation

· Amplifies & reads signal
· Compares to personal baseline
· Maps chemical profile

PROCESSING: Signal Interpretation

Joy is externalized through:
· Color & pattern shift on skin
· Peak moment crystallizes
· Haptic pulse to app

Phase 3: Define

Target Audience


General Public

Everyone, regardless of age, background, or health status, deserves to understand their own emotional chemistry.

Medical Professionals

Clinical reference — Monitor patient emotional baselines, detect depletion early, and supplement therapy with biological data.


Revisiting user flows

I mapped the end-to-end experience from sensing → visualization → reflection.

Three constraints guided every decision: low cognitive load, seamless passive tracking, meaningful moments surfaced without interruption.


Function & flow

Phase 4: Design

Introducing the Happiness Experience

Post-hackathon: I continued iterating using Claude as a prototyping partner.


Capture Happy Moments

When The Bloom detects a joy signal, the patch lights up and sends a gentle prompt. No logging, no interruption. Just a quiet acknowledgment that something good just happened.


Peak Moments Gallery

Every captured moment lives in the Archive, displayed as bubbles across day, week, month, and year views, each storing an image, audio clip, and the D.O.S.E. breakdown behind the feeling. Your happiest moments, organized by your own biology.


Depletion Check-In

The Bloom isn't only there for your highs. When your D.O.S.E. signals dip, it notices, and the patch softly checks in. The suggestions aren't generic. They're pulled directly from the moments your own body already told us made you happy.


Reflect & Analyze

The Reflection tab shows your emotional record building over time. As blooms collect, patterns begin to surface — which places, which people, which moments light you up most. It becomes a living map of your joy, growing more personal the longer you wear it.

Reflecting back on the process,

What did I learn?

Working within a 72-hour constraint taught me how to balance creativity with execution.

As a two-person team, we had to align quickly, navigate different instincts, and make fast, intentional decisions—knowing when to push an idea forward and when to let it go.

Next steps

After the hackathon, I refined the sensing mechanism to be more visually intuitive for first-time users and continued iterating on the prototype using Claude to accelerate design exploration.
