Next-Gen Train Maintenance Through AR Technology
Background & Challenge
The Mumbai Metro AR app development project is a collaboration between a leading rail simulation company and Tata Elxsi Ltd. to enhance training for technicians through an immersive Augmented Reality (AR) experience. The client specializes in rail simulation for driving and maintenance training, but traditional methods lack interactivity and detailed visualization. The AR app aims to improve learning efficiency by allowing trainees to explore and interact with virtual models of train components.
The client faced technical complexity in aligning digital models with physical objects without using QR codes or images while ensuring smooth functionality and multilingual support. Environmental factors, such as indoor lighting and minimum distance for effective use, had to be considered. Performance optimization was critical to prevent lag and motion sickness on Android tablets. The solution needed to reinforce the client’s brand message and demonstrate its commitment to advanced training methods.
Scope of work
The project involves developing an AR app to train technicians on complex train components using interactive 3D models. It includes free exploration, AR-based alignment, and real-time component details to enhance learning efficiency and user engagement. Key deliverables include:
- Develop an AR app for Android tablets with interactive 3D models.
- Enable free exploration of HVAC, Bogie, Suspension, and Gangway components.
- Provide detailed component information with text-to-speech support.
- Model alignment without QR codes.
- Optimize performance for indoor use and prevent lag.
- Deliver the final app with Unity project source code.
Solution
The solution involved developing an AR app using Unity to create an engaging and immersive learning experience for technicians. It integrated 3D scanning, dynamic content, and interactive models to improve training efficiency and engagement. Key highlights include:
- Developed an AR app using Unity for Android tablets.
- Integrated Excel files for dynamic content updates.
- Added text-to-speech for component descriptions in multiple languages.
- Conducted 3D scanning for accurate digital modeling.
- Designed an intuitive GUI for easy navigation and interaction.
- Ensured smooth performance without lag or motion sickness.
- Enabled accurate model alignment using Vuforia without QR codes.
Impact
The AR app developed by Tata Elxsi has significantly enhanced the client’s training process by providing an immersive and interactive learning experience. Trainees can explore complex train components in detail, improving understanding and skill development. The app has reduced the need for physical models, lowering costs and increasing training efficiency. The client reported higher trainee engagement and improved knowledge retention, reinforcing their position as a leader in rail simulation training. This innovative approach has strengthened the client’s brand message and resulted in a more skilled workforce capable of maintaining and operating trains with greater efficiency and precision.
