Trace

Methodology in Product Design (APD1) 2025

Trace is handheld device with hyperspectral imaging and Raman spectroscopy. Thanks to our collaboration with the Swedish police, we worked to develop new tools for detecting environmental crimes and identifying areas for improvement. We also had the opportunity to collaborate with a special unit that conducted these crime investigations. The problem identified showed that one in three samples taken by the police turn out to be negative. Hence, our goal was to reduce the number of samples needed and help detect environmental crimes without direct contact with hazardous substances. This aimed to enable fast and accurate identification of contaminated areas.

Process

Our research primarily focused on identifying and comparing a range of advanced sensors capable of detecting and visualizing areas of contamination. We conducted a thorough analysis of various sensor technologies, evaluating key factors such as sensitivity, precision, range, and ease of integration with other systems. After a comprehensive assessment, we chose to move forward with Raman spectroscopy and hyperspectral imaging, as both technologies offered exceptional accuracy. When combined, they provided complementary capabilities that allowed us to create a unified tool for detecting environmental crimes.

To simulate real-world usage, we developed several weight mockups of the device. Through this iterative process, we refined the device architecture by continuously adjusting its form to ensure that it not only housed the necessary components but also facilitated ease of use during operations. By incorporating ergonomic principles, we ensured the device could be comfortably held for extended periods, even in challenging field conditions. The ergonomics of the device played a key role in shaping its overall form, making it intuitive, efficient, and practical for police officers in the field.
