The shortage of skilled professionals is a growing problem all over the world and has a serious impact on the industry. Thus, companies are willing to train their own professionals for the company-related tasks. They are even willing to provide continuing education for their long-term employees. Especially in the area of machine engineering, it is a standard procedure to perform the training in form of on-site instructions on the corresponding machinery. Often, experienced instructors perform the training and share their knowledge with the students during a live-demonstration. The transfer of knowledge can be complicated by the fact that multiple resources in terms of people and hardware have to be brought together: Some devices may only exist in a very limited number and need to be used for daily production, which makes it difficult to schedule a training session; trainees may also be required to travel to the place of operation because the company is located at multiple sites; the experienced professionals who are serving as instructors are often integrated into various critical operations regarding the companies daily business and thus are only available for limited periods of time. The incentive of the project is to find out how innovative approaches and methods from the fields of Augmented Reality and Virtual Reality (AR/VR) can be used to enhance training procedures for companies to ease the above mentioned burdens. A multicamera system consisting of various hardware and software components is being developed, which enables remote training by recording and streaming a live training situation from multiple view points. By integrating modern interaction concepts as well as AR/VR visualisation techniques, we seek to improve the user experience for the remote training. The project developments are iteratively being examined and evaluated with relevant test scenarios resulting in an ongoing project evaluation. This project is a part of Campus to World.

eTa - efficient transportation alternatives

The development of sustainable electromobility is one of the social challenges our time, which is considered in the research project eTa. The energy efficiency of vehicles is addressed in aerodynamic projects and optimized operating strategies. In particular, non-classic vehicle concepts are in focus. Alternative mobility concepts based on non-fossil fuels need new supply structures. The optimized expansion of the loading infrastructure is therefore another issue. But even the best mobility concept is useless if it is not accepted by society and implemented by politics and business. Therefore, acceptance questions are a central element of eTa, which will be further developed. The following areas are addressed primarily by the need to reduce energy consumption: Efficiency of the vehicles Alternative mobility concepts Efficiency of mobility concepts Technical acceptance In particular, these are questions which arise only from the combined consideration of these subject areas and are usually not fully answered in classical manner. Examples of this are optimization of hybrid controls for muscle-electric hybrid light vehicles and study of the aerodynamics of ultralight vehicles where results of the classic wind tunnel tests often do not correspond to the results of the practice. Other topics that we are dealing with are predictive operational strategies for electric combustion hybrid vehicles and loss optimization, optimization of multi-stage placement of charging stations, acceptance of alternative mobility concepts.

Multisensory View Management for Augmented Reality

Augmented reality (AR) is a field of research that has seen a steep incline in attention over the last years. Recently, it has been driven by simple cell phone applications as well as the appearance of low-cost head-worn display devices such as Google Glass, and will likely see further uptake through Microsoft Hololens. Nonetheless, the field of research itself has steadily been growing for well over a decade, driven primarily by research systems, but also by increasing industry interest. The basic premise of AR is the overlay of digital imagery over real-world footage. However, how we present information in an effective way, reflecting the potential and limitations of the human perceptual system, is still an open issue. To improve the usability and performance of AR systems and applications, perceptual issues must be approached systematically: there is a need to understand the mechanisms behind these problems, to derive requirements and subsequently find solutions to mitigate effects. To focus our scope, in the proposed work we will predominantly look into advancing view management techniques, while mainly dealing with labels as main information visualization technique. Labels are the predominant mode of information communication in most AR applications and highly intertwined with view management. Labels generally hold text, numerical data or small graphical representations in a flag-like form that point towards the real-world object it refers to. The management thereof can be very challenging: for example, it may be required to order a larger number of labels that likely cause clutter and occlusion, which results in difficulties processing the provided information. Hence, without adequate view management techniques we will not be able to design effective interfaces especially when complexity rises. This is especially true once a narrow field-of-view (FOV) head-worn display device is used. These display devices are increasingly popular as high quality and affordable commercial versions become available and a higher uptake is expected. Yet, adequate view management methods specifically designed for narrow FOV are not available.   Aims and Objectives In the project, we will advance the state of the art in the following areas: Create a benchmark system that supports the research effort – it is specifically intended to create a platform for performing validations und comparative conditions, both within the frame of the research program as well as by other researchers. Create a better understanding of perceptual and interrelated cognitive issues arising when using narrow FOV AR displays for exploring increasingly complex information, and comparing these findings to medium and wide FOV displays. Develop innovative view management techniques specifically tuned towards narrow FOV displays, hereby encompassing both (a) improvements to visual management of information represented through labels as well as (b) exploring the potential and developing view management methods based on auditory and tactile cues. Create guidelines to guide the design of novel interfaces.

DoVE

The goal of the Development of Vehicle Exteriors (DoVE) project is to explore new techniques in the automated engineering of three dimensional objects. We take the crafting of the aerodynamic shells which surround velomobiles as a test case, using evolutionary methods to develop stable, aerodynamic, light-weight designs.
