This fusion of digital and physical design is a key differentiator for Granstudio. It allows their team to explore the full potential of HMI design, blending the best of both worlds to create seamless, context-aware experiences for drivers and passengers alike.

Granstudio's HMI workflow is built on three main components: physical prototypes, interactive VR, and digital prototypes. ProtoPie plays a significant role in the digital prototyping stage, allowing the team to refine user interactions and test behaviors in a real-time environment.

Physical prototypes are used to simulate and verify ergonomics, ensuring that every interaction feels natural. ProtoPie aids in this by supporting real-time interactions, so Granstudio can create prototypes that closely mimic the final experience. This allows them to assess key user interface sections, including material configurations, embedded lighting, and overall feel, ensuring that digital design aligns with physical elements.

2. Interactive VR for context-aware design

Interactive VR is essential for evaluating the user experience in various contexts. With ProtoPie, Granstudio can simulate how users interact with HMI systems in different scenarios, such as traffic conditions, weather changes, or different times of the day. This context-aware design approach ensures that Granstudio’s prototypes are robust, flexible, and tested in various environments.

3. Digital prototyping and dynamic interactions

ProtoPie truly shines when it comes to digital prototyping. Granstudio uses ProtoPie to build adaptive, responsive interfaces that adjust to various user inputs and settings. For instance, ProtoPie allows them to design interactions that adjust based on the active user profile, making the experience more personalized and reducing potential distractions for drivers.

Q: Can you talk about the challenges of linking all these prototype environments and technologies together?

Yes, that was the biggest challenges—merging everything together. In our studio, we gathered together designers and software developers to tackle this. It’s about overlaps and how different disciplines work together. The major challenge was how to combine these elements and create a unified environment.

ProtoPie made this process much easier with its connectivity, which helped us to integrate it with VR environments. We had already developed digital simulations within our team, but what was missing was the interface integration—how everything could communicate and influence each other. ProtoPie helped us solve that issue, enabling seamless interaction between different elements.

Now, we use this system for demos and user testing, and it's efficient enough to provide valuable insights throughout the design process. So, ProtoPie's connectivity was crucial in making this integration possible.

Q: What are the major trends you're seeing in the future of HMI and XR prototyping for the automotive industry?

From a design perspective, one of the main trends we see in XR prototyping for HMI design is integrating various tools into a single environment. This enables designers to experience their designs as close to reality as possible, recreating a full in-cabin experience and truly immersing themselves in the design process.

This approach helps reduce costs and time to market by allowing multiple iterative design loops, testing, and prototyping. Designers are moving beyond testing on just two screens; the future involves integrating virtual and physical environments. This allows designers to experience their work firsthand, which is a major shift we’re working on here at Granstudio.

Q: Have you ever tried to use real signals from a car with a native Android automotive system?

Actually, no, we haven’t done that yet, but we know it’s possible. For our prototyping, we don’t use real vehicle signals because we have our own platform that simulates everything. Our approach focuses on simulation, which also allows us to compare different cars during benchmarking.

We’re aware of the capability, and we aren’t ruling out the possibility of using real signals in the future. For now, we primarily use ProtoPie for simulations.

Q: Do you see the web technology becoming stronger and more important for in-car HMI development?

Yes, web technologies are becoming more important in in-car HMI development due to their cross-platform compatibility, ease of updates, cloud integration, and faster development time. They also offer a more familiar user experience for drivers, making them increasingly relevant for future systems. Additionally, web-based HMIs allow for seamless over-the-air updates, which can enhance safety and keep interfaces current without needing hardware changes. As vehicles become more connected, leveraging these technologies will be key to providing personalized, real-time services.

Q: Do you see the possibility to bridge the gap between prototyping to development in the next years? There are tools that are code-free and already compile to the target.

Of course, we are exploring the possibilities of integrating development solutions as well. We are fully aware of the tools available on the design and development market, including those that can compile directly to the target platform. However, for greater flexibility and fewer creative constraints, we prefer to first prototype original and unique designs, which we then hand over to our developers to transform into the final product. Depending on the specific needs, we choose the best tools for development, although we find code-free solutions for final HMI to be more limited and constrained in many aspects.

Q: In the context of transitioning to automotive HMI design, is it necessary to learn about the engineering aspects and ergonomic science?

The ergonomic aspects are important because HMI design is about the relation between human and interfaces. Designers must prioritize driver safety and minimize distrractions. Ergonomic principles guides the placement of controls, and the overall layout of the visuals elements to ensure that drivers can interact with the system safetly. Besides, engineering knowledge can be useful, because HMI designers need to be aware of the contraints imposed by hardware and software. This knowledge ensures that designs are feasible.

Q: Are there any starting points to start learning HMI design? from other disciplines?

HMI is a transdisciplinary field and there are several important starting points to build a solid competence in this field, like for example principles of UX Design, Graphic Design (e.g. composition, typography and color theory), Human Factors and Cognitive Psychology.

Q: How do you transition from being a UI/UX designer to an HMI designer?

I don’t think it’s that far of a transition. First, it's important to note that you don’t necessarily need to be a UI or UX designer to move into HMI design. You could come from various design backgrounds. However, what’s crucial is your approach. HMI design still focuses on the human user and interaction, and you’ll work a lot with hierarchies and interconnections between different elements.

In our studio, we don’t view HMI as just content on a screen. It’s a broader, more immersive interface that surrounds the user and even extends beyond the car in automotive HMI design. While UX and UI are good foundations, you also need an understanding of ergonomics, visual hierarchy, and readability, much like in other design disciplines.

However, automotive HMI introduces a more dynamic context. The main design principles shift to focus on safety and minimizing driver distraction, which are different from designing for personal devices. So, transitioning requires learning the specific context in which HMI interfaces operate, but overall, the shift isn’t too drastic, just different in some aspects.

ProtoPie is pivotal in Granstudio’s design process, offering a powerful and flexible platform for creating dynamic, responsive HMI prototypes. By enabling real-time interaction testing, integrating with external devices, and supporting advanced features like voice commands, ProtoPie fits seamlessly into Granstudio’s workflow.

With ProtoPie, Granstudio can push the boundaries of automotive HMI design, creating the seamless car experiences of the future.

The benefits of interactive design systems

ProtoPie benefits for design system management

Darren started his presentation by giving an overview of the history of design systems, tracing their roots back to corporate identity guidelines used in print design in the 1960s. As the web emerged, designers had to adapt these guidelines to the digital world, which introduced its constraints and opportunities. The introduction of CSS allowed for more control over styling, layout, and consistency, laying the groundwork for the structured design systems we use today.

However, the real shift toward interactive design systems came with the advent of mobile devices in 2007. With the 

, designers were suddenly dealing with new interaction models, such as touch gestures and sensors, in addition to the traditional web and desktop environments. This evolution pushed designers to think more at the component level, focusing on building systems that could scale across multiple platforms and devices.

When Google released Android, it expanded the mobile design landscape, followed by tablets, wearables, and VR headsets.

At the same time, design tools were evolving. Most designers, including Darren, initially used Photoshop, while some worked with Fireworks for web design. In 2012, Sketch emerged as the first dedicated UI tool, introducing "symbols" — reusable components that transformed the design process. These symbols were stored in libraries and led to the trend of "sticker sheets," where UI elements were laid out like Lego pieces for easy use.

"There are many ways to define a design system,"

 says Darren. Some see it as a collection of reusable components, while others view it as a set of patterns and shared practices that serve the purpose of building cohesive digital products.

He defined a design system as a tool that encapsulates all the decisions about how a product looks and behaves. The goal of a design system is to provide a unified framework that enables teams to work more efficiently and consistently.

, design systems fall into six categories: Brand, Tool, Product, Process, Service, and Practice. Darren's presentation focused on two key types: design systems as tools and products.

 include UI kits and code libraries like Bootstrap or React, which help designers and developers create digital interfaces.

 include governance, rules, and a backlog to ensure they evolve with the product.

He emphasized the critical need for aligning design and development within a system, showcasing how ProtoPie can bridge that gap. In the following sections, we’ll explore this in depth—keep reading to discover more.

The importance of interaction in design systems

While traditional design systems focus primarily on static UI components, interactive design systems incorporate motion and interaction design, which Darren identified as critical in modern product design.

Figma and ProtoPie are powerful tools that complement each other when building and managing design systems. Figma is excellent for creating static UI components, while ProtoPie brings those designs to life with advanced interaction and motion design. Here’s how they work together to streamline both design and development.

Figma: building the foundation of your design system

Figma is often the starting point for designers creating the visual foundation of a design system. In Figma, designers use UI kits to assemble static versions of interfaces. These designs serve as blueprints for developers, providing them with the visual structure they need to recreate the design in code. Figma is great at delivering these static designs, helping teams quickly iterate and collaborate on the visual aspects of their products.

However, Figma’s prototyping capabilities are basic, and while it can show simple transitions and interactions, it doesn’t cover the full scope of how a product will behave. This is where ProtoPie steps in.

ProtoPie: bringing interaction and motion to your design system

ProtoPie fills the gap between static design and real-world product behavior. It allows designers to add complex interactions, animations, and logic to the components they create in Figma. Once you export components from Figma to ProtoPie, you can simulate how users will interact with them, showcasing everything from motion effects to conditional logic.

This is especially useful for developers who need to understand how the design should behave, not just how it looks. By providing realistic, interactive prototypes, ProtoPie eliminates much of the guesswork and back-and-forth communication between design and development teams, ensuring that both teams are aligned.

Here’s a simple, step-by-step guide on how to build an interactive design system with ProtoPie and Figma.

First, you’ll begin in Figma by creating your static UI components. Once your components are ready, you can use the 

 to export them directly into ProtoPie. This is where you’ll start adding interaction and bringing the design to life.

Step 2: Create the interactive components

After importing the components into ProtoPie, the next step is to convert them into ProtoPie components. Each component in ProtoPie comes with its own set of variables, layers, and interactions, making it self-contained and easy to manage.

Keeping your components organized is key to maintaining consistency across your design system. ProtoPie, like Figma, lets you create 

 to store and manage your components. This is especially helpful if you’re designing for multiple platforms—mobile, tablet, desktop—since you can quickly switch between libraries as needed.

One of the standout features of ProtoPie is the ability to create interactive documentation. You can embed your interactive components into tools like Notion, allowing your team to not only see the design patterns but also interact with them directly in the documentation. This makes it much easier for developers and stakeholders to understand how each component behaves in the real world.

Darren highlighted several key benefits of using interactive design systems, mainly when using ProtoPie:

Interactive prototypes leave little room for misinterpretation. Developers have a clear blueprint to follow, reducing the likelihood of errors and miscommunication.

By providing a complete, interactive design system, teams can reduce the time it takes to build and launch new features. The interactive prototypes serve as a roadmap for developers, speeding up the development process.

ProtoPie helps ensure that interactions are consistent across platforms and devices. This consistency leads to a unified user experience, regardless of whether users interact with the product on a desktop, mobile, or wearable device.

Interactive design systems foster better collaboration between designers and developers. ProtoPie enables both teams to work from the same interactive blueprint, reducing the need for repeated meetings and clarifications.

ProtoPie offers a range of features that streamline design system management, making it easier for teams to work efficiently and deliver high-quality products. Here are some key benefits:

ProtoPie allows designers to create interactive prototypes without writing code, enabling faster workflows and saving time across teams. This results in a quicker path to testing and refining designs, reducing the overall time to market.

Before ProtoPie: fragmented workflow, lengthy render & preview times

Before adopting ProtoPie, Riot Games' prototyping process involved a workflow common to many companies, starting with designs in Figma, transferred via a program like AEUX, and finalized in After Effects. This workflow resulted in lengthy render and preview times, presenting several challenges:

 Using multiple applications made the process slow and hindered real-time collaboration and iteration.

 The fragmented workflow prevented the reuse of components, which complicated the development handoff and often led to misunderstandings and extended quality assurance processes.

 Static prototypes prevented stakeholders from fully experiencing designs, reducing the impact of presentations.

 The final outputs were bulky MP4 files organized in a grid-like format reminiscent of Google Sheets, which lacked interactivity and did not allow for immediate feedback. This setup made it challenging for developers to understand and execute the design intentions correctly.

Recognizing these challenges, Riot Games began searching for a tool that would better meet their needs by fitting seamlessly into their existing workflow, supporting collaboration, and allowing for high-fidelity prototypes that could easily be shared and understood across teams.
