About Carnival Hub
Carnival HUB is Carnival Cruise Line's onboard mobile app, helping guests discover activities, manage plans, make reservations, and access key ship info throughout their trip.
Carnival Cruise Line holds 21% market share, operates 27 ships across 60 destinations, and serves 3,000+ passengers per excursion.
Project Context
Carnival HUB buried guests in information overload — with so many onboard activities on offer, guests struggled to find what mattered to them and lost confidence in how to spend their limited time onboard.
Over 10 weeks with Carnival's Digital Experience Team, I led research and discovery, information architecture, and end-to-end UI/UX design to identified two complementary directions: short-term UX improvements to reduce friction, and a long-term Treasure Hunt system to turn planning into guided, playful exploration — together raising task completion from 52% to 85% in usability testing.

Part II Long-term Opportunities

Treasure hunt engagement system
Onborading
Set Context in Seconds
Quickly explains what the game is, how it works, and what you’ll get—so first-time guests feel confident, start playing immediately, and keep coming back.




Personalized Storylines
Package routine actions into Game missions
Tailoring missions, routes, messaging, and rewards (e.g., families, couples, first-time cruisers, foodies)—so the game feels relevant, reduces choice overload, and drives participation and onboard spend.

Clarity Before Commitment
Game Detail Screen
Combines story, filters, rewards, and time limits so guests instantly know what to do, where to go, and whether it’s worth joining.



Before & after
As an academic–industry collaboration, the project moved beyond deliverables to demonstrate measurable impact — validating how research-driven design can shape future digital experiences. From delivery to impact, this project turned research-driven design recommendations into meaningful improvements in clarity, engagement, and brand experience.

Design System
The challenge was balancing joyful brand energy with a clear UI. Too much fun distracts. Too much clarity feels bland.
I tested directions with Experience Boards. I used fluid gradients and rounded motion for energy, while keeping key actions high-contrast and in fixed spots for fast, confident use.
Components

Reflection
In complex, real-world contexts, UX isn’t about adding more features—it’s about reducing mental load so users can quickly understand where they are, what they can do, and what to do next. Small friction gets amplified, so the best UX decision is to keep the experience predictable: consistent key actions, clear hierarchy, and task-based guidance. Delight should support the flow, not compete with it.
Reduce confusion first. Delight comes next.
Lesson Learned
Design Within Constraints
Even without on-site testing, scenario-based simulations can reveal real user behaviors.
Design as a Strategic Lever
Aligning with KPIs and measurable outcomes connects design to business impact.
Balance Playfulness and Clarity
Emotion and usability can work together. Clear hierarchy and thoughtful motion make both possible.
