Global Food Waste Challenge (SDG 12): A VR Cooking and Food Management Application
This paper presents "Global Food Waste Challenge," an immersive VR application developed with Android Studio and Kotlin that utilizes motion-based controls, gaze interaction, and storytelling to educate users on Sustainable Development Goal 12 by simulating realistic food management scenarios and donation processes with high accuracy and engagement.

Every year, the world produces enough food to feed everyone, yet a staggering amount of it is thrown away. This waste is not just a missed meal; it represents a massive drain on the planet's resources, consuming vast quantities of water and energy while releasing greenhouse gases that warm the atmosphere. Addressing this problem is a central goal for global leaders, who recognize that changing how people think about food is essential for a sustainable future. For decades, educators have tried to solve this with brochures, posters, and videos, hoping that simply knowing the facts would change behavior. However, these traditional methods often fail to create a lasting impact, particularly among younger generations who are accustomed to interactive digital experiences. The challenge lies in moving beyond passive information to create an experience that feels real enough to shift how people make decisions in their own kitchens.
To bridge this gap, a researcher at the Ballari Institute of Technology and Management in India has developed a new kind of educational tool: a virtual reality application designed to simulate the daily choices of cooking and food management. Unlike standard educational software that relies on static text or simple images, this application places the user inside a digital kitchen where they must actively plan meals, manage ingredients, and confront the consequences of their choices. The system, titled the "Global Food Waste Challenge," uses the sensors already built into modern smartphones to create an immersive environment. Instead of requiring expensive headsets, the application relies on the phone's gyroscope—a sensor that detects how the device is tilted and turned—to move the user's view around the virtual space. By looking at different parts of the screen, the user can open virtual refrigerators and cabinets, select ingredients, and calculate how much food is needed for a specific number of people.
The core of the experience is a cycle of action and immediate feedback. As users navigate the virtual kitchen, they input data about how many people they are feeding and what ingredients they plan to use. The application then performs an instant calculation to determine if the planned meal will result in a shortage, a perfect amount, or an excess that will go to waste. If the user plans for too much food, the system does not just display a number; it triggers a simulation where the user must virtually donate the surplus to a non-governmental organization. This step is designed to create an emotional connection, showing the user that their decisions have real-world consequences beyond their own pantry. The application also includes a storytelling layer, featuring humanitarian visuals and structured lessons that reinforce the importance of responsible consumption, aiming to turn abstract statistics into a personal narrative.
The results of testing this application suggest that this interactive approach is highly effective. When researchers evaluated the system, they found that the underlying calculations were perfectly accurate, correctly identifying waste, shortages, or optimal usage in every test case. More importantly, the interactive elements worked reliably; the system successfully recognized when a user was looking at a virtual object, such as a fridge or a cabinet, with a high degree of precision. The response time was also swift, with the virtual camera moving in less than a tenth of a second after the user tilted their phone, creating a seamless feeling of control. Compared to the static systems used in previous studies, this application generated a much higher level of user engagement, suggesting that the combination of movement, immediate feedback, and emotional storytelling creates a more powerful learning environment.
While the current version runs on standard smartphones without the need for specialized headgear, the researchers see this as a stepping stone toward even more immersive experiences. The project demonstrates that it is possible to use existing technology to teach complex global issues through direct, hands-on simulation. By allowing individuals to practice food management in a safe, virtual space and see the immediate results of their choices, the application offers a new path toward the behavioral changes needed to meet global sustainability goals. The work confirms that when people are given the chance to actively participate in solving a problem rather than just reading about it, they are more likely to understand the stakes and remember the lessons.
