Letter Scent Kiosk
A concept kiosk that finds a matching scent to add onto your letter and send as a gift.
Objectives 1
Design an embedded system of a kiosk that sits in public places. The customer will be able to select a gift from appropriate information architecture, complete the transaction, and receive the physical gift.
Ideation & User Scenarios
An unexpected and different gifting experience on a kiosk.
I stayed emotionally close to the potential audience, listening to their stories, gifting experiences, and expectations. I learned how to engage with customers and received a lot of valuable feedback that helped me shape a focused, simple, and meaningful idea as the basis for my design.
Bob is a romantic person who likes expressing himself.

His crush’s birthday is coming and he wrote a love poem. He wants to make the emotion of the letter stronger.
Task Flows
Provide a letter.Discover a scent.
I separated the ideal user experience into three steps and researched the categorization of the fragrance library. The result provided me with a solid basis for understanding the information architecture.
Initially, discovering scents is designed similarly to the typical online shopping experience. Although it offers shortcuts to the best scent in the customer’s mind, I realized that it’s not the best solution to a product with such subtlety and subjectivity.
Content-based Recommendation System
The new system allows people to be subjective by offering a variety of moods to choose from. By asking people to try possible matching scents, it learns about people’s preferences and curates the results based on their feedback. This constructs a personal and intimate experience that brings joys and surprise to the exploration of scents.
Usability Testing
A sheet of test criteria for six participants.
Three friends and three strangers that I interviewed in public.
In this stage, I learned how to interact with strangers, collaborate with peers, conduct a brief interview, make notes when listening, and organize notes quickly. The concrete and informative feedback I received from a diverse group of participants greatly helped me to find design problems and iterate in the next step.
Major Iteration
New Information Hierarchy
Being able to let people change their mind is extremely important. But people shouldn’t be confused about the complexity of choices.
The new tab structure reveals itself as people go through three steps. They are able to go back to any specific step at any time before the purchase.
Physical Prototype
Building the low-fidelity physical prototype with foam core and cardboard helped me learn how the software and hardware work together to deliver a smooth and unified experience.
Objectives 2
Apply the Hallmark brand to the embedded system.
Competitive Visual Audit
Since there are no directly competing products on the market, I selected three brands that I predicted are most likely to develop similar products.
Inspiration Boards
Three distinctively different directions. I eventually chose the most unexpected and experimental one.
Style Tiles
Try a scent.
Give feedback.
Save for later.
Pick a scent.
