Hololens. Assembling the engine
slider-arrow
slider-arrow

This project involved the development of an AR prototype aimed at training workers on an assembly line in the assembly and disassembly of an internal combustion engine. The client provided a 3D engine model along with disassembly instructions. The interface was developed in German, tailored to the needs of the client’s workforce.

Project Overview

The core objective of the project was to create a proof of concept that could be used for immersive training. Users interact with the virtual engine using Microsoft Hololens. By using a central ray for targeting engine components, users tap to remove parts. Before starting, the engine can be placed in a comfortable virtual position for the user. Next to the engine, an instructional panel is available with visual renderings and step-by-step disassembly instructions.

Each removed component is added to a UI list, and parts highlight in color when selected for easier identification. The virtual engine is designed with simplified materials and color highlights, making it intuitive to follow the disassembly process. While this prototype was not integrated into actual training due to the absence of fault-finding scenarios, the client was pleased with the project’s outcome and the quick turnaround.

Solution

This concept demonstrated several key mechanics suitable for AR-based training simulations:

  • The ability to visualize high-value virtual objects in a practical context.
  • Intuitive controls using Microsoft Hololens for seamless interaction.
  • Clear visualization of combined 3D objects.
  • Instructional guidance with both image-based and text-based content, ensuring user comprehension.

This prototype serves as a strong foundation for further development, such as incorporating additional engine models, voice-activated assistants, fault detection scenarios, and user performance evaluation modules. These enhancements would make the training solution even more comprehensive for real-world applications.

Technical Details

Platform: Microsoft Hololens
Technologies: Unity, Visual Studio
Features: Ray-based component selection, interactive UI, part highlighting for enhanced focus, instructional panel with image and text guidance.

This AR prototype provided the client with a vision of how augmented reality could streamline workforce training, enhancing both engagement and comprehension. With further development, this solution has the potential to revolutionize on-the-job training in manufacturing environments.
