    The Golden Bullet: A Comparative Study for Target Acquisition, Pointing and Shooting

    Proceedings of the 2019 11th International Conference on Virtual Worlds and Games for Serious Applications (VS-Games) [4-6 Sept. 2019; Vienna, Austria]

    Abstract anzeigen

    In this study, we evaluate an interaction sequence performed by six modalities consisting of desktop-based (DB) and virtual reality (VR) environments using different input devices. For the given study, we implemented a vertical prototype of a first person shooter (FPS) game scenario, focusing on the genre-defining point-and-shoot mechanic. We introduce measures to evaluate the success of the according interaction sequence (times for target acquisition, pointing, shooting, overall net time, and number of shots) and conduct experiments to record and compare the users' performances. We show that interacting using head-tracking for landscape-rotation is performing similarly to the input of a screen-centered mouse and also yielded shortest times in target acquisition and pointing. Although using head-tracking for target acquisition and pointing was most efficient, subjects rated the modality using head-tracking for target acquisition and a 3DOF Controller for pointing best. Eye-tracking (ET) yields promising results, but calibration issues need to be resolved to enhance reliability and overall user experience.

    Computing Quality-of-Experience Ranges for Video Quality Estimation

    Proceedings of the 2019 Eleventh International Conference on Quality of Multimedia Experience (QoMEX) [5-7 June 2019; Berlin]

    2019

    DOI: 10.1109/QoMEX.2019.8743303

    Abstract anzeigen

    Typically, the measurement of the Quality of Experience for video sequences aims at a single value, in most cases the Mean Opinion Score (MOS). Predicting this value using various algorithms has been widely studied. However, deviation from the MOS is often handled as an unpredictable error. The approach in this contribution estimates intervals of video quality instead of the single valued MOS. Well-known video quality estimators are fused together to output a lower and upper border for the expected video quality, on the basis of a model derived from a well-known subjectively annotated dataset. Results on different datasets provide insight on the suitability of the well-known estimators for this particular approach.

    Energy Modelling in Rural Areas with Spatial and Temporal Data in Germany and Czech Republic

    Proceedings of the 5th International Conference on Geographical Information Systems Theory, Applications and Management (GISTAM2019) [May 3-5, 2019; Heraklion, Crete, Greece], vol. Vol. 1

    2019

    Abstract anzeigen

    One of the major challenges for the energy transition is to reconcile variable renewable energy production with stochastically changing energy demand including the pursued changes in e.g. transport like electro mobility. This requires smart systems that should be designed to minimize balancing and transmission costs. The design and modelling of such systems requires high resolution energy generation and demand data, which usually either do not exist or is not available. Methodologies to address this lack of data populate scientific literature but its replicability is limited by an inadequate level of detail in the description of the methodologies and to a larger extent by the absence or low quality of basic data. This manuscript summarizes severalyears of research in energy modelling using Geographical Information Systems as well as spatial and temporal data of the rural areas in Bavaria (Germany) and the Czech Republic. Data requirements for energy demand and energy supply including different types of users and technologies are addressed. Irreconcilable data gaps are presented, examples to fill data gaps as well as recommendations for future necessary developments are provided

    Using spatiotemporal data to evaluate renewable electricity self-sufficiency of municipalities and states in Bavaria and the Czech Republic

    Geophysical Research Abstracts, vol. 21

    2019

    Abstract anzeigen

    Photovoltaics and wind power are the fastest growing and best established renewable energy technologies of today. Both are usually presented as the preferred option for energy systems to reach high shares of renewables but their integration is not an easy task due to their varying availability and its grid's feed-in. This work presents the likelihood of municipalities in Bavaria (Germany) and federal states in the Czech Republic to reach high penetration of photovoltaics and wind power until 2050 by taking into account demographic changes and alternative regulatory developments. To accomplish this, spatial development potential of wind power for three different sizes of turbines (10m, 50m and 137m) and free-standing photovoltaics are calculated for the whole study area using a mix of official and open data. Time series of electricity generation are constructed for every single potential area using physical models of the technologies. These models rely on solar radiation, temperature and wind speed time series from the COSMO-REA6 regional reanalysis as input data. Moreover, current total electricity demand per type of sector (residential, agricultural and industrial) is distributed in space using population and land use data from the LUISA territorial modelling platform of the European Commission. The population and land use forecast of the latter data set is utilized to estimate electricity demand per administrative unit for 2030 and 2050. The yearly values of electricity demand for each administrative unit are transformed into hourly electricity demand time series using German and Czech standard load profiles. Finally, an optimization model is employed to estimate if the local renewable potential per administrative unit together with storage systems are sufficient to cover the local demand under current and future conditions. Results are presented using maps covering the whole study area. These do not only show that massive storage systems would be required in order to supply electricity only based on photovoltaics and wind power, but also that the feasibility of achieving this could be considerably different between geographic and climatic areas with similar conditions.

    How to Better Find Historical Photographs in an Archive Geographic Driven Reverse Search for Photographs

    Digital Humanities Conference 2019 (DH2019)

    2019

    Abstract anzeigen

    Historical photographs are important sources for documenting the past of humanity. They can serve as evidence of our society’s history but are also objects of research themselves. Today, the standard format for describing the geographical origin of a photograph is to assign a geoname or point coordinate of the location of the photographer to the image. In view of historical photographs, we are dealing within this operation with spatial uncertainty. In most cases it is not possible to define the exact location of the photographer in form of coordinates in e.g. regions that afflicted strong environmental changes over time. The aspect of spatial uncertainty is also present, when describing the location of the photograph`s origin by a so-called geoname. A geoname can be comprehended to different extents. For example, it can name a region, a city or just a small part of a city. Therefore the question of the exact spatial origin cannot be answered by solely using a geoname. Such aspects of uncertainty in the localization of historical photographs complicate the retrievability in archives for spatially oriented search. Since the photographs cannot be found by entering search queries in the archive, their potential to serve as a data source for research cannot be fully exploited.

    Can Geoinformation Help to Better Protect Informal Settlements? - A Concept For the City of Medellín

    Gi4DM 2019 – GeoInformation for Disaster Management, vol. XLII-3/W8

    2019

    DOI: 10.5194/isprs-archives-XLII-3-W8-115-2019

    Abstract anzeigen

    New contributions to disaster research need to address the increasing vulnerability of informal settlements in a changing climate situation. Informal settlements are frequently built in hazardous areas and are often left out of traditional disaster risk management concepts. Hence, formal and informal societal structures, as well as technical systems to warn against, handle or mitigate natural hazards, need to evolve. Within the project Inform@Risk we are addressing these issues based on a case study in Medellín (Colombia). Here, as a result of civil conflicts informal dwellings were partly constructed by people displaced from rural areas. They are mainly located in the urban peripheral areas along steep and unstable slopes, where the resettlement of all inhabitants at risk of landslides is unfeasible. This contribution presents the technical infrastructure and the concept to incorporate geodata from different sources in an integrated landslide early warning system for some selected informal settlements of Medellin. Special attention is given to possibilities on how building societal institutions, supported by information systems, increases local resilience. Using geoformation as a basis, we will combine classical participatory planning methods with digitally assisted concepts. These include combining satellite and UAS based remote sensing data with terrestrial sensor networks, crowd sourcing and citizen science to collect volunteered geographic information about the settlement and its environmental parameters, as well as distribute this information and disseminate warnings to the local population.

    Assessing Middle and Low Voltage Grid Requirements in Bavaria for the Decades to Come

    Shaping a Sustainable Energy Future: 9th Colloquium of the Munich School of Engineering (August 1, 2019)

    2019

    Abstract anzeigen

    Increased urbanization and rural depopulation processes are going to produce a high impact on the future electric grid. The impact of these developments on the shape and characteristics of the electricity transmission and distribution systems is however today not discussed as much as the transition to renewable energies. Current research dedicated to electrical grids focuses on the integration of renewables and the related necessary measures to increase stability and reliability. Topics such as the changes in the shape and length of grid as well as redundant infrastructure issues due to demographic changes are barely studied in previous literature. The present work is a pioneer attempt to address these issues using a spatially explicit approach for the state of Bavaria in Germany. The main consequence emerging from depopulation is not only the increase on size and number of very low populated regions but also growing city-sizes, which up to now already have difficulties of being supplied with sufficient energy. Especially the difference in needs for the electricity grid length per person is going to be even more pronounced than already today. The resulting costs per person to provide everyone with a reliable electricity supply will diverge similarly between urbanized and rural regions. The medium and low voltage grids should be capable of delivering sufficient electricity to users and simultaneously allow the integration of distributed renewable generation installations. While data for analysing the transmission systems (high voltage grids) are widely available, spatial and attribute data of the medium and mainly the low voltage grids are scarce. The first step for the analysis of urbanization and rural depopulation effects on the future Bavarian low and medium voltage grid therefore is the estimation of todays’ electric grid. The present study proposes a method that relies on a) a data set that estimates the topology of the medium and low voltage grids of Bavaria (Germany) based on a minimum spanning tree principle, and b) data from the LUISA territorial modelling platform of the European Commission to calculate grid requirements for the years 2030 and 2050. Two alternative paths are proposed to carry out grid requirement estimations. The first is based on population data and the second on land use data. Grid length typologies are created based on population thresholds or land use types for 2010. The same typologies are afterwards used to extrapolate grid requirements for the future, which follow the population and land use changes of the LUISA data set. The future estimations are therefore in conformity with the forecasts utilized by the European Commission. As a reference base map for comparing grid estimations based on population or land use clusters, the length of the grid calculated based on a) is cumulated for each square kilometer so that the resolution and extend match the LUISA data for Bavaria (the map on the left is the reference map for the medium voltage grid). Results show that when estimating the current electricity grid based on land use clustering, it is not possible to get close to the beforehand calculated reference map. Using population density clusters on the other hand, makes it feasible to estimate the current electric grid based on mean or median grid lengths per cluster category. When comparing statistics as well as the resulting maps, the best method to produce a grid map based on clusters, is when using the median grid length per population cluster category (e.g. map on the right for the medium voltage grid). When using the mean of each category, the results seem not to be as precise. In the particular case of Bavaria, the forecast shows that total grid length requirements will decrease until 2030 and 2050. In rather urbanized regions, the grid needs to be prepared for expansions, while in rural regions existent grid infrastructure will become unnecessary. Hot-spots of such changes can be located using the results of the presented methodology.

    This paper argues that a digital infrastructure is vital to the work of cultural institutions today. In order to develop a well running system for smaller museums, which are hardly ever center of focus of donating companies and sponsors, we develop four measures, an integrated content management and digital signage system, an application for smart phones and a 3D city model, that will allow the visitors to connect with the city's history, virtually and physically.
