The expected quality on manufactured components in the automotive industry is high, often with an accuracy of tenths of a millimeter. The conventional methods used to ensure the manufactured components are very accurate, but they are both time consuming and insufficient and only a small part of the produced series are analyzed today. The measurement is performed manually in so-called measurement fixtures. Where each component is fixed and predetermined points of investigation are controlled with a dial indicator. These fixtures are very expensive to manufacture and they are only compatible with one specific kind of component. Nowadays, great volumes of material are scrapped from these procedures in the automotive industry. Hence, there is a great need to increase the amount of controlled components without affecting the production rate negatively. This project was carried out for the relatively new company Viospatia, which is a spin-off company based on research from Luleå University of Technology. They have developed a system that automatically measures each component directly at the production line with the use of photogrammetry technology. This makes it possible to discover erroneous components almost immediately and the manufacturer gets a more distinct view of their production and its capability. The aim of this thesis has been to investigate how a user interface should be developed to be as user-friendly as possible without limiting the system’s functions. The objective has been to design a proposal of a user interface adapted for the intended user, creating value and is easy to use. The progression has been structured around a human-centered approach expedient for interaction design, where the developing phase, containing analyze, design and validate, is performed through iterations with continuous feedback from users and the project’s employer. The context, where the intended solution is supposed to be used, was investigated through interviews and observations at the involved companies. In the project ...
