Interactive KIOSK




UX/UI design


Stemmed from an Adobe XD/Behance challenge, Kozy is an interactive prototype for a candle purchasing kiosk. 



Adobe XD


Think about a consumer experience and redesign it in a digitally interactive and innovative manner.

At the time of the challenge, I was home for a family and friends dinner before Valentine's day. I shared the guidelines of this challenge with the guests; after some  people shared some irks they had with typical consumer experiences such as using a vending machine, one person mentioned recently buying a gift for his significant other for Valentine's day. He talked about buying her a set of candles and his experience in the candle store and how the overbearing candle smells prevented him from distinguishing different aromas.

Context & Research

01 - 

Users Research

To find out more about troubles with the candle purchasing experience I interviewed friends and family members. I asked non-leading and some general questions to ensure conversation flowed and to get interviewees in the context of purchasing candles. Once I felt the interviewee was comfortable, I proceeded to ask more in-depth question, yet still open-ended, so as to collect honest and more valid feedback.

  • Have you ever been in or near a candle store before?

  • What was that experience like? 

  • For stores that sell candles or scented things like perfumes, what has been your experience with them?

  • Do you like how these stores smell?

  • Where do you buy candles? 

  • Why do you buy candles?

  • When do you buy candles?

  • How do you decide what candles to buy?

  • How is your experience with buying candles? Would you change anything about that experience if you had the chance to?

Overall Trends & Insights
  • The overwhelming smells in candle stores mask the different smells of candles and complicates the purchasing process.

  • Having a break in between smelling candles is an important step for customers because otherwise, they can't distinguish smells. 

  • 63% of interviewees buy candles for other people.

  • 75% of interviewees mentioned having trouble browsing candles when walking into storefronts.

Intended Users

Given these findings, I came up with two users representative of what I believed the main customers of my redesigned experience would be.


Jenny Zhang, is a Candle Enthusiast


  • To have a relaxing atmosphere at home

  • To be able to accurately identify a candle scent

  • To spend less time searching for and testing candles and more time enjoying them


Bob Ness, has Smell Sensitivities


  • Not feel nauseated or sick whenever he goes candle shopping

  • Smell the candle before purchasing

  • Easily buy candles for whatever occasion

To mediate the overbearing smell in candle stores, I envisioned an interactive candle vending machine, where a user would smell a scented strip (much like one tests a perfume at Sephora) before deciding to purchase a candle

​Given browsing issues, candles should be displayed under specific categories such as occasions and smells so that users can logically access and view available candles. It seems like adding a “gift”/wrapping feature would make the interface desirable to a wider range of users, such as users looking to get a gift for someone.

Designing a Solution

Initial Sketches & Wireframes

The screen component was to feature the main interactive component that would satisfy the challenge guidelines. I began with a paper mockup to get a general sense of what the customer experience would feel like. Full wireflow of sketches can be found here: 

(Note: at this point my Adobe trial expired so I used Figma which is a similar tool to create wireframes)

Testing my Concept

To put my concept to the test I asked people to perform a specific task: 


Click through the paper prototype; purchase a candle you like, test its smell, add it to your cart, gift wrap it, and checkout.

From the user testing, I gathered this data:

  • Average task time: 30s

  • Task success rate: 94% of participants were able to get to the checkout screen

  • Participants took longer to find the test  smell button than the add cart button

  • Only 65% clicked on the gift wrap button

  • Satisfaction Questionnaire: 90% of users reported that the interface was intuitive and the process was engaging.

Note: Participants' ages ranged from (21-57) and consisted of 4 males and 6 females. 

With these results, I decided to make small changes to the interface:

  • Outline the scent button in a bright color.

  • Make gift wrapping button as important (in size) as other buttons on the checkout screen
