Institute of Machine Tools and ManufacturingOpen OpportunitiesWalking has been proven to create the best sense of presence while exploring
virtual environments. However, walking in virtual environments comes with the
constraint that the virtual and the physical space must have the same
dimensions. This limitation restricts the size of the virtual spaces. Various techniques have been developed to overcome this issue, such as RDW and impossible spaces. Although significant progress has been made with these methods, exploring large virtual environments can still lead the user to reach the boundaries of the physical space. Therefore, a safety mechanism is needed to prevent the user from colliding with the walls. The most popular safety mechanism is having resets, which are messages displayed to the user asking them to stop and perform a certain action that turns them away from the wall before continuing the exploration. However, resets reduce immersion and thus should be avoided as much as possible. - Computer-Human Interaction

| The process forces during machining with abrasives is critical for efficiency of the process and quality of the final product. The forces arise from different mechanisms like sliding, plowing and cutting. Although material removal occurs mostly by chip formation, a considerable portion of grinding energy goes to sliding between workpiece and dulled abrasive particles. This project aims to create a sliding force model to accurately predict forces with changing contact conditions in an abrasive process simulation. - Manufacturing Engineering, Mechanical Engineering
