    AmI-VR: An Accessible Building Information System as Case Study Towards the Applicability of Ambient Intelligence in Virtual Reality
    (Mensch und Computer 2021 - Tagungsband, 2021) Götzelmann, Timo; Kreimeier, Julian; Schwabl, Johannes; Karg, Pascal; Oumard, Christina; Büttner, Florian
    Ambient intelligence represents a paradigm in which the user does not react to the environment, but vice versa. Accordingly, smart environments can react to the presence and activities of users and support them unobtrusively from the background. Especially in the context of accessibility, this offers great potential that has so far only been demonstrated for individual user groups. To overcome this limitation, we propose the automated, user- and context-related adaptation of the modality as well as locality of the representation of building information in the form of both an adjustable table as well as two displays on the basis of a prototype for a library information center. For being independent from material and regulatory restrictions and for better planability (especially with the ongoing COVID-19 pandemic) we used in addition to the hardware components also a Virtual Reality simulation, which proved to be very useful. Further optimization and evaluation will be needed for a more in depth understanding and dissemination in the long run, yet our prototype aims to help fostering further activities in the field of ambient intelligence, accessibility and virtual reality as a planning tool.

    BikeVR: a virtual reality bicycle simulator towards sustainable urban space and traffic planning
    (Mensch und Computer 2020 - Tagungsband, 2020) Ullmann, Daniela; Kreimeier, Julian; Götzelmann, Timo; Kipke, Harald
    While becoming more and more aware of the ongoing climate change, eco-friendly means of transport for all citizens are moving further into focus. In order to be able to implement specific measures, it is necessary to better understand and emphasize sustainable transportation like walking and cycling through focused research. When developing novel traffic concepts and urban spaces for non-motorized traffic participants like bicycles and pedestrians, traffic and urban planning must be focused on their needs. To provide rare qualitative factors (such as stress, the perception of time and attractiveness of the environment) in this context, we present an audiovisual VR bicycle simulator which allows the user to cycle through a virtual urban environment by physically pedaling and also steering. Virtual Reality (VR) is a suitable tool in this context, as study participants find identical and almost freely definable (virtual) urban spaces with adjustable traffic scenarios. Our preliminary prototype proved to be promising and will be further optimized and evaluated.

    Real World VR Proxies to Support Blind People in Mobility Training
    (Mensch und Computer 2018 - Workshopband, 2018) Kreimeier, Julian; Götzelmann, Timo
    Mobility training is an essential part of blind people’s education in order to move in public spaces. In order to safely learn new routes in public space, however, a seeing trainer must assist the blind person. With the increasing availability of VR hardware, it is possible to transfer real spatial environments to virtual representations. The digitized environments can be used as a basis for this training without safety problems by real world hazards. This allows to cope with the limited resources of sighted assistants and enables blind people to become more independent. We propose to capture real public spaces (such as sidewalks, train stations etc.) and make them in this way ascertainable. Orientation and mobility can be trained in this digital model via multimodal sensory feedback while involving intuitive locomotion and white cane exploration. This paper sketches the related work and proposes our novel approach. Furthermore, we suggest additional improvements on our ongoing research.
