| Summary: | The aim of the thesis was to develop a usable mobile application prototype to be used in the underground mining environment. In order to fulfill the aim, the research question How can a mobile application be designed for usability with focus on operability for an underground mine? was researched, analysed and answered. The main methods for driving the design process were ISO 9241-210, Human-centred design for interactive systems, requirement engineering and conceptual design. The results of the thesis were based on qualitative data, collected from semi-structured interviews from five respondents. These respondents had a background as a operator in underground mines in different countries. The qualitative data was analysed and interpreted into functional and non-functional user requirements. The user requirements in parallel with design principles were used to produce a final concept that would be transformed from a low fidelity into a high fidelity prototype. The high fidelity prototype was developed using Android Studio, Java and later tested and evaluated using SUS questionnaire and usability heuristics to rate the overall usability of the application . The answer to the research question lied in the methodology used in this thesis. This was achieved by involving the stakeholders, people affected by the future design in the entire process, with different methodology during the different phases of the design process.
