Speed Dating: Prototyping

This post will be a quick recap of the speed dating session at the start of the semester. The goal was to create prototypes for a possible master’s thesis topic. In class we divided into two groups and talk about each others prototypes in a small amount of time. Due to my decision on swapping majors after the first semester, this task was a challenge for me. I had no clue what to do actually and just tried to connect my previous knowledge with the goal of this task. My love for typography always played a big role in my work and I tried to develop a playground to interact with letters and their movement.

The first concept was to have some kind of object that will is suppused to be thrown against a wall. It should invite people to let out their emotions. Imagine it like a rage room but the collision of the object and the wall is interactive. Depending on the speed of the object, the wall displays a collection of words as type.

The second prototype was a more relaxing way to interact with typography. Based on movement and impact on pressure plates, the wall shows different letters being formed by the people. My idea was to show their behavious in form of typography. Letters are always expression a kind of personality. In this case I want the people to connect with letters and get to know the power of expression through typography.

Class Feedback

It was interesting to see that noone acutally understood what I actually wanted to express. This also lead to a feedback saying the second concept could be offensive to some extent. As I mentioned in the first paragraph, it was hard to create something understandable as a lofi prototype, so I understood the reactions and i tried to reflect how I could make it more understandable. So I knew I had to get more experience to learn more about prototyping and interaction.

Lo-Fi Prototyping & Speed-Dating Reflections: Designing an Elevator for a 1000-Story Building

Introduction: A Thought Experiment in UX Design

How would you design an elevator interface for a 1000-story building? While this scenario may seem surreal, it presents an exciting challenge in user experience design. Inspired by a Google interview question, I decided to explore this concept and create a lo-fi prototype. The goal was to think through the navigation experience in such an extreme case, considering how users would interact with the system efficiently and intuitively.

Defining the Context & Target Users

To make this concept work, I first established some basic assumptions:

  • The building serves both residential and office purposes, potentially housing thousands of people
  • Multiple elevators exist, but each one needs a way to direct users efficiently
  • The elevators operate using a restricted access system where only authorized individuals can reach specific floors

The target users would include:

  • Residents – People living in the building
  • Employees – People working in office spaces
  • Visitors – Guests visiting residents or businesses
  • Security Persons – Ensuring safety and restricted access where necessary

The Prototype: Navigating this big Skyscraper

My prototype focused on the elevator interface, aiming to make navigation simple despite the overwhelming number of floors. In that 20 Minute Prototype Session was included:

  1. Entry Screen – Users authenticate using an NFC card, PIN, or biometric login to verify access / Guests login via their name and the name of the host
  2. Floor Selection – A personalized interface displaying only authorized floors to reduce cognitive overload
  3. Elevator Assignment – Users are directed to a specific elevator to optimize efficiency
  4. In-Elevator Controls – A secondary screen inside the elevator allows floor changes or emergency actions, ensuring flexibility mid-ride

Speed-Dating Prototype Discussion: Key Takeaways

The Speed-Dating session provided invaluable feedback from different perspectives. Here are some key insights:

1. Initial Reactions – What Problem Am I Solving?

  • Many participants struggled to recognize the interface as an elevator control system
  • Some assumed it was a hotel check-in or a security login screen
  • The concept of restricted floor access confused some users

2. Feature Suggestions – What Would You Add?

  • Instead of buttons labeled Save and Cancel, participants suggested clearer icons like a checkmark and a [X]
  • Emergency contact options were missing and should be easily accessible
  • Accessibility concerns arose, suggesting the need for a tactile number pad and Braille support

3. If My Prototype Had a Dating Profile…

  • The elevator system would market itself as “Your fastest and most efficient ride to success” or “Seamless mobility, one floor at a time.”
  • While the system served everyday users, i think the real customers would be building developers looking to optimize user flow in high-rise buildings

4. Future Vision – What Would Make This TED-Worthy?

  • While no 1000-story buildings exist today, high-rise architecture continues to evolve
  • Future cities may require advanced wayfinding systems, making this prototype a glimpse into possible urban design challenges

5. Unexpected Feedback – What Surprised Me?

  • The first login screen was misleading, making users think they were logging into a website rather than an elevator
  • Participants felt that unauthorized users could bypass security by following someone into restricted floors
  • The experience was unusual since most people are accustomed to standard button-based elevator panels

Final Thoughts & Next Steps

Exploring this extreme scenario was a fun and thought-provoking design exercise. However, given its impracticality, I won’t continue developing this prototype. Instead, I want to shift my focus to real-world mobility and wayfinding challenges, potentially designing solutions for navigation in large public spaces like airports, malls, or grocery stores.

This experience has reinforced how UX design is about clarity, accessibility, and user expectations. Designing for mobility is not just about efficiency, it’s about making interactions intuitive and seamless.

In the next blog post, I will explore potential project directions that build upon the learnings from this prototype.

2.1 Documentation & Reflection: Speed-Dating My Lo-Fi Prototype

Last semester, my research focused on how UX/UI design can make mental health apps more calming and accessible, and how AI can provide personalized, empathetic support. I explored micro-interactions, color psychology, and AI-driven emotional intelligence to understand what makes digital mental health tools effective.

This time, I wanted to explore physical, tangible interactions for well-being—something that doesn’t require a screen or notifications but still guides users toward emotional regulation.

The Three Prototypes

For this exercise, I created three lo-fi prototypes:

Weekly Mood Tracker: A simple, analog way to log emotions over the week using color-coded entries for easy reflection.

Self-Reflection Cards: A deck of prompts designed to encourage mindful self-exploration and emotional processing.

Breathing Circle: A guided breathing tool made of paper, where users rotate a circular element to synchronize their breath with a visual cue.

Choosing the Breathing Circle

While all three prototypes engage users in self-awareness and well-being, I chose to bring the breathing circle to class because it best embodies my research goal: designing interfaces that guide users toward calmness in a simple, intuitive way. Unlike mood trackers or reflection tools, the breathing circle introduces a hands-on, meditative experience that requires minimal effort—ideal for moments of stress.

Speed-Dating My Prototype

In class, we shared our prototypes in a Speed-Dating/Sharing session, presenting them to different classmates in quick succession. This was an exciting way to gather feedback and refine ideas. Some of the key insights from my classmates included:

  • Great for children in schools – One student noted that the breathing circle could be useful in classrooms, similar to a fidget gadget, helping children focus while also providing a calming mechanism.
  • Ideal for bedtime – Another student said they would love to use it before bed to relax, which sparked the idea of making the prototype more tactile with textures and even usable in the dark.
  • A minimalist, portable tool – Someone pointed out that, since it’s thin and can be small, it’s perfect for carrying on public transport or while traveling. Its minimalistic design keeps the focus solely on breathing, without distractions.
  • A sensory experience – A classmate suggested adding resistance to the movement (like a soft fabric hinge) to make turning it feel more grounding.

What is My Prototype Trying to Address?

The breathing circle is designed to address a key challenge in mental health support: how to create intuitive, low-effort tools for emotional regulation. Unlike mood-tracking apps or chat-based AI support, this tool is immediate and physical—it doesn’t require users to think, analyze, or type, just breathe. This prototype is particularly suited for:

  • Commuters and travelers – Its thin, compact design makes it easy to use on the go, whether on public transport, at an airport, or in a waiting room.
  • Children and adults needing focus – It can function as a calming fidget tool, helping with concentration in schools, workplaces, or even at home.
  • People looking for a screen-free relaxation method – No notifications, no distractions—just a simple, intuitive breathing guide.

Potential Features & Future Iterations

Based on the feedback, I’d love to explore:

  • Tactile Elements – Soft materials, textured surfaces, or raised patterns to enhance sensory engagement.
  • Glow-in-the-Dark or Low-Light Adaptation – So it can be used before bed without needing external light.
  • Personalization – Adjustable speed settings, so users can customize their breathing pace.
  • Elastic Resistance – Adding a slight resistance to the movement to make it more grounding and engaging.

If My Prototype Had a Dating Profile …

“Looking for a mindful moment? I’m a simple, no-fuss tool that helps you slow down and just breathe. I work best in quiet moments, whether you’re feeling stressed, anxious, or just need to unwind. Small, discreet, and always ready to help—swipe right for relaxation!”

Final Thoughts

This session reinforced how valuable it is to test even the simplest ideas. The breathing circle started as a basic paper prototype, but through conversation and iteration, it could evolve into something more immersive and widely useful. The feedback also reminded me that not all mental health tools need to be digital—sometimes, the most powerful solutions are the simplest, most tangible ones.
