- Abstract
- This master thesis focused on evaluating and designing the user interface of a camera production machine used in an industrial manufacturing environment. The project was conducted in collaboration with a global technology company and aimed to improve usability, clarity and operational support through a user-centered design approach. The work began with a comprehensive pre-study of the existing interface including heuristic evaluation, usability testing, interviews, and surveys, to identify strengths, limitations, and user needs across different roles. Based on the findings from the pre-study, an iterative design process was applied, involving ideation, low-fidelity prototyping, and high-fidelity refinement. Design decisions were grounded... (More)
- This master thesis focused on evaluating and designing the user interface of a camera production machine used in an industrial manufacturing environment. The project was conducted in collaboration with a global technology company and aimed to improve usability, clarity and operational support through a user-centered design approach. The work began with a comprehensive pre-study of the existing interface including heuristic evaluation, usability testing, interviews, and surveys, to identify strengths, limitations, and user needs across different roles. Based on the findings from the pre-study, an iterative design process was applied, involving ideation, low-fidelity prototyping, and high-fidelity refinement. Design decisions were grounded in established usability heuristics, industry standards, and user feedback. Two iterations of Lo-Fi prototypes were developed and evaluated to explore alternative layouts, interaction flows, and information structures, followed by a Hi-Fi prototype that consolidated and refined the most effective solutions. Multiple rounds of usability testing were conducted throughout the process to guide design iterations and validate improvements. The final interface introduced clearer process visualization, including a newly introduced progress overview that provides continuous insight into unit status. In addition, error and alarm handling are presented in a more structured manner, and overall visual clutter has been reduced. Quantitative results from the System Usability Scale (SUS) evaluations indicate a substantial improvement in perceived usability compared to the existing system. While the redesigned interface demonstrates significant usability gains, the study also highlights challenges related to accommodating users with varying levels of expertise and differing operational needs. The resulting proof-of-concept user interface provides a validated foundation for future development of production machine interfaces. (Less)
