Dimono has two parts - a "participatory museum experience" to transform distant historical facts into engaging and relatable narratives for Gen Z, and "path collector" as a tangible reminder of their journey to encourage reflection and revisit to reinforce the delivery of museum's message to their audience.
01 Embodiment
The visitors can choose a dinosaur active in Triassic period they are most resonated to and mimic their posture to start their journey. We let the visitors to become dinosaur to know about dinosaur.
02 Onboarding
The visitors receive their headsets and path collector, going through onboarding to understand the basic interaction.
03 Interact with Paintings
Approaching and lingering at a painting for over 2.5 seconds activates an informative display. Information appears in the head-up display.
04 Transition
When entering new period of time, visitors will be stopped by virtual boundary. It will introduce how the previous period end and what dinosaur they evolved into to acknowledge their progress.
05 Interact with Fossils
When interacting with the fossils, visitors can appreciate the authentic dinosaur and the information and stories spatially together by using guided hand gestures. This is the fundamental interaction for all the fossils in the exhibition.
06 Path Collector
Each fossil display is paired with an incubator. Visitors use the collector to trigger the interaction and collect unique features of their dinosaur fellows. This creates a personalized path through the exhibit.
07 Talk with Iconic Dinosaurs
In addition to the basic interaction, the iconic dinosaurs like t-rex and Dippy will be brought to life and talk to the visitor proactively. Their mood depends on the relationship between them and the dinosaur the visitor is embodying. The storytelling is designed to inspire the resilience of life with museum’s core value.
08 Talk with Iconic Dinosaurs
when visitors leave the exhibit, they can retrieve their experience by scanning unique marks on their collector.These marks represent the diverse features of the dinosaurs they encountered, creating a lasting memory of their journey.
We used laser cutter and 3D printer to create the physical path collector and incubator. We also used Unity and Meta Quest 3 to create workable MR prototypes for testing and iterating.

Our client, CMNH, is committed to deepening the understanding of our natural world, to foster a sense of collective responsibility for our future. We’re focusing on their Dinosaur in Their Times exhibition, known for its famous holotypes specimens & reconstruction of the dinosaur habitats.
Our target audience, Gen Z visitors, whom the museum is currently struggling to retain. They were observed to often just pass through the exhibit and marvel at the wonders. We also conducted one-on-one interviews to understand their needs and values.
Gen Z visitors are characterized by shorter attention span and high digital literacy supported.
It may be more challenging for them to stay focused on traditional, less interactive museum, potentially impacting their ability to retain information presented in these formats.
The Gen Z are actually very interested in dinosaurs. They grew up with Jurassic parks. The dinosaur stories often impress them a lot once explained or revealed.
However, the rich stories within the exhibition are not reaching Gen Z visitors. The static displays don’t quite capture their fleeting interests, leading them miss the chance for deeper engagement in the exhibition narratives.
We discovered that the designed route is chronological, the earliest dinosaurs are shown first and follow the path of evolution. However, the curations of the spatial narratives of evolution are often neglected due to the scattered and overwhelming information.
By incorporating XR interactions and augmented reality, we aim to spark curiosity and enhance learning through immersive storytelling. Our goal is to convert passing interests into sustained engagement ultimately envisioning CMNH as an interactive, participatory museum.

We conducted primary research on U-Haul's exiting service. Their service is comprehensive but overwhelming. Therefore, we did an interface audit on their U-Haul website & app and ecosystem analysis to learn and find insights into the current user flow. We discovered that:
The navigation is rather overwhelming. We observed chaotic information architecture, wordy & confusing description and repetitive but hard-to-find access towards instructions.
U-Haul's service is very comprehensive. However, it also makes the customers lost in the searching. What's more, the connection between customers with adding-on service like Moving Helper is very loose and unguided.
Through 8 + one-on-one user interviews and online research, we found common themes in grievances and complaints.
Qualified Interviewees
21+ Years Old Do-It-Yourself Movers
"I'm afraid of driving a big truck. There is no rear mirror!"
"We were all not familiar with trucks and the interior and accidentally broke a handle."
Anxiety about driving trucks & misuse of equipment
Design for anxiety relief and instruction
"None of the records reflect the movers I ordered, no emails or text nor the website. Does this mean they are not booked and I need to book someone else?"
Challenges in accessing information & alternation
Design for accessible information in real-time
"The way U-haul helps me choose the truck isn't effective. The customer service makes me wait for hours."
"I had to cancel my reservation and rebook just to change the moving date."
Challenges in choosing the right service

To address our research question in our design, we followed these four design principles:
This system blends various technologies such as digital projection mapping, Mixed Reality (MR) interactions, and natural language processing.
Digital Projections Mapping
XR Interactions
Nature Language Processing(NLP)
To seamlessly guide our visitors, we created an integrated visual system.
01 Information Panel
Visitors initiate interaction with gaze control which will trigger the info to appear within 2.5 seconds.
Eye Control
To interact with the fossil, hover over to reveal the info panel, pinch for more information, and grab to examine fossils closely. We designed the hierarchy to avoid info overload.
Hover

When design the sound space in MR experience, we used the following principles:
Bring the users back to the dinosaurs’ time and environment with 3D spatial audio; Aural feedback to user’s interactions; Enhance the emotional and non-intrusive narrative events; Maintain immersion and consistency across platform.
In a market dominated by CT injectors with control room displays and limited on-machine controls, our challenge was to innovate a user experience with advanced on-machine touchscreens to meet and exceed current clinical procedures.
Even with few direct examples, market research showed growth potential for syringeless injectors. It also showed the need for intuitive on-machine controls to streamline workflows for better user interaction and efficiency.
Insight 1: Look Into the Future
We should focus on design UX for the new syringeless injectors, which are poised for growth due to their efficiency, safety, and waste reduction.
Insight 2: User Habits
Preserving conventions, such as color coding (blue for saline, green for contrast medium), enhances usability and eases transitions.
Insight 3: Workflow Integration
Recent injector systems allow customized patient protocols and usage tracking to improve operational efficiency. Visibility on the machine can further enhance accessibility.
Insight 4: Screen-Driven Clarity
On-machine touch screens should be designed to offer intuitive controls and simulation capabilities, simplifying training and reduce dependency on remote systems.
I led discussions across teams to improve the input information architecture and wireframes by asking straightforward and critical questions about feedback and requests. We also utilized paper prototypes for quick, remote cross-team evaluations, enabling efficient design enhancements.
Collaboration Adjustment
Fast Prototyping
Refined Information Architecture & Wireframes
We decided to focus the design to create an experience that prioritizes task optimization, customer-helper synergy, and immediate information access, ensuring a seamless and stress-free experience for all users.
We identify our core customer as the do-it-yourselfers who feel anxious and overwhelmed by the moving process. The Moving Helpers as the U-Haul contractors are our secondary users, providing professional accessibility service to those in need and getting extra income.
Based on our immersive research, we identified 3 main roles that Sammy acts as, which are guide, reminder, and cheerleader. The percentage of the 3 roles and personalities that Sammy exhibits when interacting with customers and moving helpers varies depending on the current scenario.
More detailed storyboard & user journey map are created to refine the narrative, incorporating feedback, and enhancing visual storytelling to align better with the design focus.

Being in charge of company's open-source project is both rewarding and challenging, sharpening my ability to navigate limited research resources and deliver a practical, impactful and compelling proposal aligned with real-world needs.
There was limited research resource dedicated to open-source project. Researching problem required me to use all resources I have including experienced designers in other teams, my professors and even cold-messaging related startups on LinkedIn to refine the project.
Designing systems for underserved communities is challenging. It requires constant reflection to avoid biases and a commitment to staying open-minded and continuously learning.
As we learnt that incorporating digital simulations into the CT injector enhances the intuitiveness of the injection process. The challenge was to achieve this without overloading system resources, ensuring high reliability crucial in a medical context.
I collaborated closely with clients and engineers to determine the optimal amount of essential animated simulation through technical testing and iterative feedback.
After determining the key animated simulations, I started to explore desirable ways to both communicate impactful message and efficiently utilize resources, especially for injection and fluid simulation.

We tested UI components using paper prototypes to fast iterate the positions and angles of UI components. And then we built a digital demo with Unity. The design of path collector and incubator keep iterating when we updated spatial UI component.
Paper Prototypes
The rapid prototyping helped us test the spatial postion and angle of the UI components.
Unity Prototypes
Unity demo helped us test the scale and position of Egg UI in spatial space; Test the “pat” and “distance grab” gesture usability; Test the usability of interaction with skeleton and user flow.
Physical Prototypes
The path collector and the incubator are the key to enter the AR interactions. They should not only act as a working prop but also an attractive piece of designed product.
The arrangement of UX components aims to minimize visual disruption and easy and ergonomic reaching.
‘Sammy’ is the intelligent conversational assistant we design to integrate in the U-Haul app. The mechanism and system of Sammy is designed according to the design focus we generated based on our research.
U-Haul introduced it's first version of its "Sammy U" character in 1953, named after the company's founder.
Style Identification
The visual design is informed by U-Haul’s brand. It takes cues from U-Haul’s boxy, yet rounded equipment and incorporates core values like reliability and stability into its tone.
Final Form
Our final visual design began with a more abstract representation of a box and landed at a more literal design that felt more on-brand with U-Haul. The idea of an active opened box speaks to the core user experience for U-Haul service.
Motion Design
Curated visual cues and motion states, fostering more natural and engaging tech interactions. Sammy's varied motions add personality and clarify messages to users.
Our emphasis was on ensuring optimal reading legibility specifically tailored for mobile users, maintaining alignment with U-Haul's brand identity throughout the design system.
We developed a UI design system that incorporates U-Haul's branding elements, encompassing a cohesive color palette, information cards, icons, and buttons.
The app's design features two distinct user paths: one for users with upcoming orders and one for starting brand new orders.
When a user starts a conversation, a compact pop-up screen captures and exhibits the inquiry, preventing abrupt transitions to new pages. This pop-up then expands to a mid-height page, showcasing all dialogues, arranged from the bottom upward.
Here are the final interfaces for the redesigned U-Haul app. These screens cover the customers' pre-moving experience, Moving Helper collaboration & moving day (driving) experience.
Designing a unique visual interface involved navigating the client’s cautious decision-making process. The client often leaned towards familiar, traditional styles, seeking safety in what was known. Our challenge was to find the sweet spot to elevate the product and maintain competitiveness.
Conducted iterative design adjustments based on client feedback, maintaining and learning from high visual standards while introducing innovative elements.
The development team expanded the interface using initial components, but inconsistencies in screens revealed the need for standardized guidelines. I proposed a design system across all device to ensure consistency and scalability in future designs.

To transform the natural history museum journey for Gen Z visitors, empowering them with knowledge that bridges the past and present, inspiring stewardship for our collective future.
As one of the biggest projects I was in charge of, the CT injector project strengthened both my technical and interpersonal skills, making me a strong team player.
Working in medical design requires close cooperation with industrial design, human factors, and engineering teams. Maintaining tight collaboration across disciplines and open for iteration ensures that the design meets both high standard market and functional regulatory requirements.
Educating clients requires skillful communication, as they may not always realize that their requests might not be feasible. I discovered that using their language and visualizing ideas effectively can bridge understanding gaps, leading to better decision-making and outcomes.
Leading this project gave me the opportunity to work closely with developers, project managers, and top decision-makers. I learned that asking questions clearly stating requests and expectations to clarify uncertainties are essential for team efficiency and ensures everyone is aligned.
My Piles of Paper Prototypes
Our new design makes U-Haul’s services not only more efficient, but also more inclusive and accessible, which in turn supports more diverse users and aligns with the principle of social responsibility. An expanded customer base also supports the growth of the shared economy. What’s more, the feasibility of Sammy is high, leveraging existing new technology like generative AI, and GPT-4.
A smart conversational assistant designed for U-Haul, simplifies the moving process and empowers customers to move independently, ensuring accessibility and satisfaction.
