As part of my Bachelor's thesis, I developed Loc:Scel, a digital assistant designed to optimize the work of criminal investigators during the crucial first hours of a crime scene investigation. The project aimed to modernize communication, streamline data documentation, and improve coordination among investigation teams, addressing the limitations of outdated and inefficient practices.
Loc:Scel is a digital companion designed to support police officers during crime scene investigations. It streamlines data collection, enhances situational awareness, and facilitates real-time coordination. With an interface optimized for clarity and speed, it enables officers to capture evidence efficiently and communicate effectively under pressure. The system’s adaptability allows for integration into daily procedures, reducing manual effort while improving decision-making. By focusing on actual field needs, Loc:Scel introduces a more responsive and structured approach to complex, time-sensitive operations in modern police work.
To understand the challenges faced by criminal investigators, the project began with expert interviews at the Stuttgart police department, complemented by stakeholder mapping and benchmarking digital tools already in use. A low-fidelity prototype enabled early usability testing, revealing that communication, documentation, and coordination at crime scenes were major friction points. These insights formed the basis for tailored user requirements and design guidelines. The research highlighted the importance of integrating new solutions into established workflows without disrupting critical field operations.
Deep user engagement revealed the gaps between existing workflows and digital potential. Early testing validated that simplicity and clarity outweigh feature density—especially in high-stress scenarios. Integrating with existing systems proved essential for acceptance among law enforcement professionals. Most importantly, designing with the field, not just for it, enabled solutions that feel natural, purposeful, and immediately useful in complex operational contexts.
The system consists of a mobile-first application structured around three core functions: documentation, communication, and coordination. Officers can log observations and evidence in real time, access shared data streams, and receive updates from colleagues and headquarters. A modular interface adapts to different roles and responsibilities, while intuitive navigation minimizes cognitive load. Secure data handling and offline functionality ensure reliability even in remote or unstable environments. Loc:Scel acts as a central node that connects field activity with operational oversight, transforming fragmented workflows into a coherent, digital ecosystem.
