Problem:
Traditional methods of drug testing in traffic stops involve invasive procedures like blood or urine tests, which are time-consuming and often uncomfortable for individuals. These methods delay law enforcement processes and can hinder timely justice.

Solution:
The introduction of "Substance:ID" aims to revolutionize this process by using a non-invasive technique that analyzes fingerprint sweat to detect drugs. This technology provides accurate results quickly, making it an invaluable tool for traffic police.

Process:
The development of Substance:ID involved a meticulous design and prototyping phase, focused on enhancing user experience and interface. Collaborating closely with local police in Umeå, the team conducted extensive testing to ensure the device was both effective and user-friendly. This collaborative effort has led to a refined product that promises to set new standards in law enforcement procedures.

Through this innovative approach, Substance:ID is set to significantly improve the efficiency and humaneness of drug testing in policing, marking a significant step forward in the integration of technology and law enforcement.

In the Substance:ID project, haptics played a crucial role in enhancing the user interface for both police officers and subjects involved in drug testing. The device was designed with tactile feedback to assist officers in operating it accurately even in low visibility or challenging conditions. This feature ensures that the process is intuitive and minimizes the risk of errors during testing, thereby increasing the reliability and efficiency of drug detection during traffic stops.
