Användarcentrerad Gruvmaskinstyrning 2030 : Design av Extended Reality gränssnitt för ökad effektivitet och säkerhet i underjordsgruvor
Sammanfattning: The history of Swedish mining industry goes far back in time and is today one of Sweden's largest exports. Epiroc Industrial Design Competence Center in Örebro is constantly working to develop solutions for safer and more efficient mines. Automation and remote control are two innovations that are currently in the spotlight for development in the mining industry. Another innovation that, according to future forecasts, will increase in the upcoming years is the use of Extended Reality (XR). XR includes the concepts of Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR) and provides the opportunity to create virtual objects that can be used in conjunction with reality to enhance information. Based on these innovations and challenges a task has been developed that can be summarized in the following mission statement: "develop a remote-controlled concept that, with the help of reinforced information, enables safer work for mining operators in 2030". Thus, the purpose of this assignment is to show how future control of mining machines can be done 10 years in the future. As this project focuses on a future concept, a new competence of operators will be needed. XR technology creates new conditions for the interaction and experience of the machines. Therefore, the target group is not limited to today's miners, but mainly focuses on tomorrow's miners, where technology enthusiasts are seen as the primary target group. To support the work process and the design choices that have been made, a literary study of the areas of cognition, Human Machine Interaction (HMI), user interface and user experience has been conducted. The area of cognition intends to describe how people uses their senses in decision making. HMI deals with autonomous processes and how they are used in the mine today. In the case of user interfaces, the design guidelines that apply to the graphic design of interfaces are explored. While usability describes the theory for good usability and user experience for human interaction withdigital systems. The work process used in the assignment is an iterative process and is based on IDEO's user-centered three-phase model consisting of the phases of inspiration, ideation and implementation. In the initial phase of inspiration, different methods have been used to support the work of exploring the context, the user and its needs. Interviews with today's miners and a survey have been used to gather information about the target groups. This resulted in two different personas as well as a user journey. During the second phase of ideation, the aim was to implement methods that generate a wide variety of ideas, which are then examined, narrowed down and then concretized into early prototypes. During this phase, three design sprints were performed according to an iterative scrum form. These were information, feedback and interaction. From the first sprint, inform, a concept was developed that described how different kinds of information should be visualized. During the second sprint, feedback, a scenario was developed that described how the solution should be visualized and what kind of feedback the system should provide. The third and final sprint, interaction, resulted in different sequences where interaction with the machine took place and how these interactions should be illustrated using AR. Based on the different results from the design prints, this was combined into a final prototype consisting of an animated mining machine with visual information and an animated contextual environment. The final concept has been developed to assist the operators with a semi-automated system where the operator can control mining machines remotely. This is done through a touch-based interface where the operator can see a camera view from the machine in real time with reinforced information applied using AR technology. The information helps the operator to work safely remotely and creates a more efficient mining process that is adapted for the operators in 2030.
