Building Aerospace UIs from Video Demonstrations

TL;DR: Forget static prototypes; Replay lets you build functional aerospace UIs directly from video demos, capturing user behavior and converting it into clean, working code.

The aerospace industry thrives on precision and rapid iteration. Yet, UI development often lags, stuck in cycles of static mockups and hand-coded implementations. This disconnect wastes valuable time and introduces inconsistencies between design intent and final product. The problem isn't a lack of talented engineers, but a broken process that fails to leverage the rich data available in user demonstrations and testing videos.

The Problem with Traditional UI Development in Aerospace#

Aerospace UI development faces unique challenges:

• •High Stakes, High Complexity: Aerospace systems demand unparalleled reliability and usability. Errors can be catastrophic.
• •Stringent Regulations: Compliance with industry standards like DO-178C adds layers of complexity.
• •Data-Rich, User-Centric Design: Modern aerospace UIs are driven by vast amounts of real-time data and designed around specific user workflows.

Traditional methods, relying on static mockups and manual coding, struggle to address these challenges effectively. Screenshot-to-code tools offer a marginal improvement, but fundamentally miss the mark. They only capture the visual appearance, ignoring the crucial element of user behavior. What happens when the pilot taps that button? What's the sequence of actions in a critical flight maneuver? Screenshots can't tell you that.

Introducing Behavior-Driven Reconstruction#

The solution lies in Behavior-Driven Reconstruction, a paradigm shift that treats video demonstrations as the source of truth for UI development. This is where Replay shines. Unlike tools that merely convert images into code, Replay analyzes video to understand user intent and reconstruct working UI components that faithfully replicate the demonstrated behavior.

Replay leverages Gemini's powerful video analysis capabilities to:

• •Identify UI Elements: Automatically detect buttons, text fields, charts, and other UI components within the video.
• •Track User Interactions: Analyze mouse movements, clicks, and keyboard inputs to understand how users interact with the UI.
• •Infer User Intent: Determine the underlying goals and motivations behind user actions.
• •Generate Functional Code: Produce clean, well-structured code that replicates the demonstrated behavior.

This approach offers several key advantages:

• •Faster Development Cycles: Reduce development time by automating the translation of video demos into working code.
• •Improved Accuracy: Ensure that the final UI accurately reflects the intended user experience.
• •Enhanced Collaboration: Facilitate communication between designers, developers, and domain experts.
• •Reduced Errors: Minimize the risk of errors by capturing and replicating user behavior precisely.

Replay in Action: Building an Aerospace UI from Video#

Let's illustrate how Replay can be used to build an aerospace UI from a video demonstration. Imagine a pilot demonstrating a new flight planning feature in a flight simulator. The demonstration video captures the pilot's interactions with the UI, including selecting waypoints, adjusting flight parameters, and reviewing the flight plan.

Step 1: Upload the Video to Replay#

The first step is to upload the video demonstration to Replay. Replay supports various video formats and resolutions.

Step 2: Replay Analyzes the Video#

Replay analyzes the video, identifying UI elements, tracking user interactions, and inferring user intent. This process typically takes a few minutes, depending on the length and complexity of the video.

Step 3: Review and Refine the Generated Code#

Once the analysis is complete, Replay generates functional code that replicates the demonstrated behavior. You can review and refine the generated code to ensure that it meets your specific requirements.

typescript
// Example: Generated code for handling waypoint selection
const handleWaypointSelection = async (waypointId: string) => {
  try {
    const response = await fetch(`/api/waypoints/${waypointId}`, {
      method: 'GET',
      headers: {
        'Content-Type': 'application/json',
      },
    });

    if (!response.ok) {
      throw new Error(`HTTP error! status: ${response.status}`);
    }

    const waypointData = await response.json();
    // Update the UI with the waypoint data
    updateWaypointDisplay(waypointData);

  } catch (error) {
    console.error("Error fetching waypoint data:", error);
    // Display an error message to the user
  }
};

const updateWaypointDisplay = (data: any) => {
  // Logic to update the UI elements with the fetched data
  console.log("Updating waypoint display with:", data);
  // Example: Assuming you have a state variable called 'waypointDetails'
  // setWaypointDetails(data); // Assuming you're using React's useState
};

// Example usage (assuming waypointId is passed from a UI interaction)
// handleWaypointSelection("waypoint-123");

Step 4: Integrate the Code into Your Project#

Finally, you can integrate the generated code into your aerospace UI project. Replay supports integration with popular frameworks and libraries, such as React, Angular, and Vue.js.

Replay vs. Traditional Methods: A Comparison#

💡 Pro Tip: Use Replay's style injection feature to seamlessly integrate the generated UI with your existing design system.

⚠️ Warning: While Replay automates much of the UI development process, it's crucial to review and test the generated code thoroughly to ensure accuracy and reliability, especially in safety-critical aerospace applications.

Benefits of Using Replay for Aerospace UI Development#

• •Accelerated Development: Reduce development time and get your aerospace UIs to market faster.
• •Improved Usability: Ensure that your UIs are intuitive and easy to use by capturing and replicating user behavior.
• •Reduced Costs: Lower development costs by automating the UI development process.
• •Enhanced Safety: Minimize the risk of errors and improve the safety of your aerospace systems.
• •Real-World Accuracy: Generates UIs based on real-world user demonstrations, not theoretical designs.

📝 Note: Replay's product flow maps provide a visual representation of the user's journey through the UI, helping you identify potential usability issues.

Real-World Example: Reconstructing a Flight Management System (FMS) Interface#

Imagine a scenario where an aerospace company needs to update the UI of their Flight Management System (FMS). They have a series of videos showing pilots using the current FMS interface to perform various tasks, such as entering flight plans, adjusting navigation settings, and monitoring aircraft performance.

Using Replay, they can upload these videos and automatically generate code for the new FMS interface. The generated code will accurately reflect the behavior of the current FMS interface, ensuring a smooth transition for pilots. Furthermore, Replay allows the development team to easily iterate on the generated code, adding new features and improving the overall user experience.

typescript
// Example: Handling FMS data updates
const updateFMSData = async (data: any) => {
  try {
    // Validate the incoming data (important for safety-critical systems)
    if (!validateFMSData(data)) {
      console.error("Invalid FMS data received");
      return;
    }

    // Send the updated data to the backend system
    const response = await fetch('/api/fms/update', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
      },
      body: JSON.stringify(data),
    });

    if (!response.ok) {
      throw new Error(`HTTP error! status: ${response.status}`);
    }

    // Update the local state with the new FMS data
    setFMSData(data);

  } catch (error) {
    console.error("Error updating FMS data:", error);
    // Display an error message to the user
  }
};

const validateFMSData = (data: any): boolean => {
  // Implement robust validation logic here
  // Check data types, ranges, and consistency
  // Example:
  if (typeof data.altitude !== 'number' || data.altitude < 0) {
    return false;
  }
  return true;
};

// Example usage (assuming data is received from a user interaction or a sensor)
// updateFMSData({ altitude: 35000, airspeed: 450, heading: 270 });
