Abstract

The objective of the present deliberations was to systematise our knowledge of static visual variables used to create cartographic symbols, and also to analyse the possibility of their utilisation in the Augmented Reality (AR) applications on smartphone-type mobile devices. This was accomplished by combining the visual variables listed over the years by different researchers. Research approach was to determine the level of usefulness of particular characteristics of visual variables such as selective, associative, quantitative and order. An attempt was made to provide an overview of static visual variables and to describe the AR system which is a new paradigm of the user interface. Changing the approach to the presentation of point objects is caused by applying different perspective in the observation of objects (egocentric view) than it is done on traditional analogue maps (geocentric view). Presented topics will refer to the fast-developing field of cartography, namely mobile cartography. Particular emphasis will be put on smartphone-type mobile devices and their applicability in the process of designing cartographic symbols.

Abstract

Three-dimensional (3D) models created with computers and educational applications designed using such models are used in the medical field every day. However, there is a lack of macroscopic demonstration applications built with digital 3D models in the field of veterinary pathology. The aim is to build a fully interactive 3D educational web-based augmented reality application, to demonstrate macroscopic lesions in kidneys for educational purposes. We used open source and free software for all 3D modelling, Augmented Reality and website building. Sixteen 3D kidney pathology models were created. Kidney models modelled in 3D and published as WebAR are as follows: normal kidney, unilateral neurogenic shutdown with atrophy, hydronephrosis, hypercalcemia of malignancy tubular nephrosis, interstitial corticomedullary nephritis, renal infarct, multifocal petechial hemorrhages, polycystic kidneys, renal masses, multifocal nephritis, pigmentary nephrosis, papillary necrosis, glucose-related rapid autolysis (pulpy kidney), pyelonephritis, renomegaly and kidney stones. With the workflow shown here, it has been presented as a feasible model application for human pathology and presented to educators, researchers and developers who have 3D models and AR in their field of interest. To the best of the authors’ knowledge, this is the first study on Web-Augmented Reality application for veterinary pathology education.

Abstract

The publication reflects the current situation concerning the possibilities of using augmented reality (AR) technology in the field of production technologies with the main intention of creating a tool to increase production efficiency. It is a set of individual steps that respond in a targeted manner to the possible need for assisted service intervention on a specific device. The publication chronologically describes the procedure required for the preparation and processing of a CAD model. For this preparatory process, the PTC software package is used which meets the requirements for each of the individual operations. The first step is the routine preparation of CAD models and assemblies. These are prepared based on real models located on the device, and their shape and dimensions correlate with the dimensions of the model on the device. The second phase is the creation and timing of the disassembly sequence. This will provide the model with complete vector data, which is then paired with the CAD models in AR. This phase is one of the most important. It determines the location of the model concerning its relative position on the device, provides information on the relocation of parts of the model after the sequence is started, and essentially serves as a template for the interactive part of the sequence. The last two phases are used to connect CAD models with vector data, determine their position for the position mark, and prepare the user interface displayed on the output device. The result of this procedure is a functional disassembly sequence, used for assisted service intervention of a worker in the spindle drive of the Emco Mill 55 device.

Abstract

Presently, digitalization is causing continuous transformation of industrial processes. However, it does pose challenges like spatially contextualizing data from industrial processes. There are various methods for calculating and delivering real-time location data. Indoor positioning systems (IPS) are one such method, used to locate objects and people within buildings. They have the potential to improve digital industrial processes, but they are currently underutilized. In addition, augmented reality (AR) is a critical technology in today’s digital industrial transformation. This article aims to investigate the use of IPS and AR in manufacturing, the methodologies and technologies employed, the issues and limitations encountered, and identify future research opportunities. This study concludes that, while there have been many studies on IPS and navigation AR, there has been a dearth of research efforts in combining the two. Furthermore, because controlled environments may not expose users to the practical issues they may face, more research in a real-world manufacturing environment is required to produce more reliable and sustainable results.

Abstract

The aim of this paper is to indicate the preliminary conditions that should be met by the concept of extended knowledge. Cognitive artifacts undoubtedly affect human cognition and knowledge. Research on knowledge should therefore take into account significant technological changes. In this paper, I make use of the concept of the Extended Mind, and in epistemological research, I use the reliabilist theories of justification. The effect of this combination is the analysis of the phenomenon of extended knowledge on the examples of extended perception and extended memory. Research conducted in the field of extended epistemology and telepistemology provides a significant support.

Abstract

Hundreds or even thousands of defects can be found during the building acceptance, hence the need for solutions which will facilitate the defect management, including identification, costing and repair. The aim of the paper is to present the possible use of BIM to support the defect management process during the acceptance of apartments in multifamily residential buildings. The paper presents a concept of quality control support application called MWBIM (Map of Knowledge BIM) which will collect data about discovered construction defects, their recording and servicing with the BIM technology. MWBIM will run based on Building Information Modelling (BIM), Augmented Reality (AR), Case-Based Reasoning (CBR) and maps of knowledge. There are three phases in the operation of the application: preparatory phase (planning the order of acceptance meetings and elements to be checked), acceptance phase (data collection and assigning them to the building information model) and the reporting phase (reports generation, assigning defects to contractors, follow-up of repair status). The intended uses of the application are mainly personnel involved in the acceptance of apartments.
