4.3 Interactive prototypes
6 min read•august 20, 2024
Interactive prototypes are powerful tools for designers to test and refine user experiences before development. They enable early of user flows, facilitate better communication among team members, and allow for user testing and feedback collection.
Designers can create interactive prototypes using no-code or code-based tools, depending on their skills and project needs. The process involves planning interactions, wireframing, adding interactivity, and iterating based on user feedback to create a more user-centered final product.
Benefits of interactive prototypes
- Interactive prototypes enable designers to test and validate user flows and interactions before investing time and resources into development, reducing the risk of building the wrong thing
- By simulating the functionality and behavior of the final product, interactive prototypes facilitate better communication between designers, developers, and stakeholders, ensuring everyone is on the same page
- Interactive prototypes allow for early user testing and feedback, enabling designers to iterate and refine the design based on real user insights, resulting in a more user-centered final product
Fidelity vs interactivity
- Fidelity refers to how closely a prototype resembles the final product in terms of visual design, content, and functionality, while interactivity refers to the level of user interaction and dynamic behavior a prototype supports
- Low-fidelity prototypes (sketches, wireframes) are quick to create and focus on basic layout and structure, while high-fidelity prototypes (detailed designs, functional prototypes) are more time-consuming but provide a more realistic representation of the final product
- The choice between fidelity and interactivity depends on the stage of the design process and the specific goals of the prototype, with lower fidelity being suitable for early-stage exploration and higher fidelity being better for user testing and stakeholder buy-in

Planning interactive prototypes
Defining interactions and flows
- Before creating an interactive prototype, it's essential to define the key interactions and user flows that need to be simulated, focusing on the core functionality and user goals
- This involves mapping out the different screens, states, and transitions that make up the user journey, considering edge cases and error scenarios
- Defining interactions and flows helps ensure the prototype covers all the necessary aspects of the user experience and provides a clear roadmap for the prototyping process
Wireframing before prototyping
- Creating wireframes before diving into interactive prototyping helps establish the basic layout, information architecture, and content hierarchy of the product
- Wireframes serve as a foundation for the prototype, providing a clear structure and allowing designers to focus on the interactions and behaviors without getting distracted by visual design details
- By wireframing first, designers can iterate quickly on the overall structure and flow of the product before investing time in creating a more detailed interactive prototype
Creating interactive prototypes
Adding interactivity to wireframes
- Once the wireframes are created, designers can start adding interactivity to simulate user interactions and flows, such as button clicks, form submissions, and navigation between screens
- This involves defining hotspots, linking screens, and specifying the desired behavior for each interaction, using the prototyping tools' built-in features or custom code
- Adding interactivity to wireframes brings the prototype to life, allowing users to experience the product's functionality and flow in a more realistic way
Prototyping user flows
- Interactive prototypes should simulate the key user flows and scenarios that are critical to the product's success, such as onboarding, core tasks, and error handling
- This involves creating a series of screens and interactions that guide the user through the flow, considering different paths and decision points along the way
- By prototyping user flows, designers can test and validate the overall user experience, identifying potential issues and opportunities for improvement
Animations and transitions
- Incorporating animations and transitions into interactive prototypes can enhance the user experience and provide visual feedback on interactions and state changes
- This can include micro-interactions (button hover states, loading indicators), transition animations between screens, and more complex animations that convey relationships or hierarchy
- When adding animations and transitions, it's important to consider performance, accessibility, and user expectations, ensuring they enhance the experience without causing confusion or distraction
Simulating dynamic content
- Interactive prototypes can simulate dynamic content, such as personalized recommendations, real-time updates, or user-generated content, to provide a more realistic representation of the final product
- This can be achieved through data-driven prototyping, using real or dummy data to populate the prototype's content and interactions
- Simulating dynamic content helps test how the design adapts to different scenarios and edge cases, ensuring a more robust and flexible user experience
Testing interactive prototypes
Usability testing with prototypes
- Interactive prototypes are invaluable for conducting , allowing designers to observe how users interact with the product and identify potential usability issues
- Usability testing with prototypes can be done remotely or in-person, using a variety of methods such as task-based testing, think-aloud protocol, or unmoderated testing
- By testing with interactive prototypes, designers can gather valuable insights into user behavior, preferences, and pain points, informing design decisions and improvements
Gathering user feedback
- Interactive prototypes provide an opportunity to gather feedback from users, stakeholders, and team members throughout the design process
- This can be done through formal usability testing sessions, informal feedback sessions, or asynchronous feedback tools built into the prototyping platform
- Gathering user feedback helps identify areas for improvement, validate design decisions, and build consensus among team members and stakeholders
Iterating based on feedback
- The insights and feedback gathered from testing interactive prototypes should be used to iterate and refine the design, addressing usability issues and incorporating user suggestions
- This involves prioritizing feedback based on impact and feasibility, making necessary changes to the prototype, and re-testing to validate the improvements
- Iterating based on feedback ensures the final product meets user needs and expectations, reducing the risk of costly changes later in the development process
Best practices for interactive prototypes
Balancing fidelity and speed
- When creating interactive prototypes, it's important to strike a balance between fidelity and speed, depending on the stage of the design process and the goals of the prototype
- Low-fidelity prototypes are better suited for early-stage exploration and rapid , while high-fidelity prototypes are more appropriate for user testing and stakeholder buy-in
- Designers should choose the appropriate level of fidelity based on the time and resources available, the complexity of the interactions, and the intended audience for the prototype
Focusing on core interactions
- Interactive prototypes should focus on the core interactions and user flows that are critical to the product's success, rather than trying to simulate every possible interaction and edge case
- By prioritizing the most important interactions, designers can create prototypes that are more focused, easier to create and maintain, and more effective at communicating the key aspects of the user experience
- Focusing on core interactions also helps keep the prototype's scope manageable, allowing for faster iteration and testing cycles
Documenting interactions for developers
- When creating interactive prototypes, it's important to document the interactions, behaviors, and edge cases for developers who will be responsible for implementing the final product
- This can include annotations, user flow diagrams, state transition maps, and other forms of documentation that clearly communicate the intended functionality and behavior
- By documenting interactions for developers, designers can ensure a smooth handoff and reduce the risk of misinterpretation or miscommunication during the development process
Accessibility in interactive prototypes
- Interactive prototypes should consider accessibility from the outset, ensuring that the product is usable by people with diverse abilities and needs
- This involves following accessibility guidelines, such as providing alternative text for images, ensuring sufficient color contrast, and supporting keyboard navigation
- By incorporating accessibility into interactive prototypes, designers can identify and address potential barriers early in the design process, creating a more inclusive and user-friendly final product
