The article presents the results of a quantitative-qualitative study that examined the experiences of children and early childhood education teachers with multi-layered interactive materials in which augmented reality technology was implemented. The article also addresses issues related to support (MIEM) for selected cognitive processes of early childhood education students. The research was conducted within the framework of the Ministry of Education and Science's program titled: Pupil circles create innovation. The study involved 1153 early childhood education students between the ages of 7 and 10, as well as their teachers, who constituted a group of 41 early childhood education teachers. A triangulation of research methods was used in the study. For the group of students, a diagnostic survey method was used, for which a survey questionnaire was developed on the Kahoot platform and an in-depth interview using an interview questionnaire. For the group of teachers, a diagnostic survey method was used, for which a survey questionnaire was developed. The survey was implemented using the Computer Assisted Personal Interview technique on the Google Forms platform. On the basis of the conducted research, conclusions were developed in terms of the main objective of the research, which was: preliminary identification of the potential for using MIEM in the context of cognitive processes in early childhood education. The results of the research indicate that early childhood education students received the introduced innovation into the teaching process to a very positive degree. First of all, MIEM resulted in high motivation for learning. The result of which was a significant number of memorized messages contained in MIEM. It should also be added that this fact can have an impact on students' memory and perceptiveness. It can also be tentatively concluded that MIEM can have an impact on cognitive processes in particular on thinking and imagination. This conclusion follows directly from the type of technology that allows generating things previously difficult to visualize. In addition, the experiences of teachers who participated in the study indicate that MIEMs provide new opportunities for experimentation and interactive learning. According to the teachers, MIEMs make it possible to support the teaching and learning of nature, mathematics, as well as other subjects. Early childhood education teachers enthusiastically welcomed the use of AR, as well as seeing this technology as a solution to the problems of implementing the principle of viewability in early childhood education.

: The authors of the current study aimed to propose a calibration method for accurate augmented reality visualisation using an optical see-through head-mounted display, and to qualitatively evaluate visualisation accuracy for the application in computer assisted surgery. Methods: An adaptation of stereo single-point active alignment method was proposed as the calibration procedure together with verification. Three tests were performed: display of points in 3D space, on the plane and on the surface of a skull phantom on inexperience users (5 participants) and experienced users (17 participants). Results: The highest accuracy of visualization was obtained for skull phantom visualisation for an inexperienced user (3.00 mm, std 0.75 mm), while the lowest accuracy was obtained in a 3D visualisation test for an inexperienced user (22.95 mm, std 18.04 mm). The largest error was related to the depth component and amounted to 18.49 mm, std 18.10 mm for an inexperienced user. Conclusions: It is possible to achieve relatively high visualisation accuracy (less than 5 mm for visualisation in space) for selected users but providing it for the group of inexperienced users seems to remain a major challenge. The accuracy of point indication can be substantially and statistically significantly increased by visualising objects on surfaces. The proposed methods and obtained results can serve as a basis for further implementation of augmented reality visualisation on an optical see-through head-mounted display in applications requiring high-quality augmented reality guidance of manual tasks.

This paper considers the problem of QR codes detection in digital images. In particular, the approach for detection of QR codes is proposed. The approach is based on histogram correlation between the reference image of QR code and the input image. In particular the input image is firstly divided into blocks. These are next used to build binary map of regions similar and dissimilar in terms of histogram to the image of QR code. On the binary map the morphological operations are next applied in order to remove outliers and identify the QR code. The results of applying the introduced approach to various images are presented and discussed. Different lighting conditions, image resolutions and orientations of QR codes are considered.

Assisted Living systems aim to improve life quality of their users giving context relevant guidance accordingly with their location and hour of the day. Most of commercial systems depend on complex/expensive infrastructure and still their positional information is not sufficient to take advantage of modern interfacing devices such as head-up displays or pico-projectors. We describe in this paper the design of an Assisted Living system capable to offer such guidance with on-site Augmented Reality, without introducing changes in the environment and using off-the-shelf equipment. The system can take advantage of wearable computing devices with embedded camera by determining the user position and orientation by using Visual Odometry and SLAM techniques. With this data, advices can be exhibited automatically by merging it seamlessly to the environment using augmented reality. In order to assess the efficacy of our system, we performed pilot tests in health care centres and residences using a prototype of a low-cost wearable device which displays the information through an embedded pico-projector.

The authors address the problem of passive navigation in large buildings. Based on the example of several interconnected buildings housing departments of the Lublin University of Technology, as well as the conceptual navigation system, the paper presents one of the possible ways of leading the user from the entrance of the building to a particular room. An analysis of different types of users is made and different (best for them) ways of navigating the intricate corridors are proposed. Three ways of user localisation are suggested: RFID, AR and QR markers. A graph of connections between specific rooms was made and weights proposed, representing “the difficulty of covering a given distance”. In the process of navigation Dijkstra’s algorithm was used. The road is indicated as multimedia information: a voice-over or animated arrow showing the direction displayed on the smart phone screen with proprietary software installed. It is also possible to inform the user of the position of the location in which he currently is, based on the static information stored in the QR code.

In this paper, the authors discuss a methodology to enhance multibody systems simulations using Augmented Reality (AR) implementation. The AR deals with the use of live video imagery which is digitally processed and augmented by the addition of computer generated graphics. The purpose is to illustrate how recent developments in computer-aided design and augmented reality can improve the realism and interactivity when simulating the movement of digital mock-ups. The paper discusses hardware and software implementations and an overview of several illustrative examples. The basic idea is described starting from a simple simulation of a falling body subjected to gravity with the initial conditions set nteractively by the user. Then, a more complex interactive simulation of the kinematics of a robot whose end-effector can be grabbed and moved by the user is presented. Finally, the real time dynamic simulation of a slider crank mechanism is discussed. The integration between AR and multibody simulation has revealed to be very useful for didactical purposes and collaborative design.

W pracy autorzy przedyskutowali metodologię usprawnienia symulacji wielobryłowej poprzez zastosowanie tzw. Rzeczywistości Poszerzonej (Augmented Reality – AR). Metodologia ta obejmuje obróbkę cyfrową obrazu pozyskanego kamerą z rozszerzeniem polegającym na dodaniu do tego obrazu grafiki komputerowej. Celem pracy jest pokazanie, na ile najnowsze osiągnięcia komputerowo wspomaganej obróbki obrazu mogą poprawić wrażenie realizmu zapisywanych cyfrowo obrazów i polepszyć interaktywność z użytkownikiem podczas symulacji ruchu uzyskanych makiet rzeczywistych przedmiotów. Zaprezentowano kilka przykładów z omówieniem zastosowanych programów i parametrów sprzętu komputerowego. Podstawowa idea została przedstawiona na przykładzie ciała spadającego pod wpływem siły ciężkości na inny obiekt przy możliwości interakcji użytkownika, który wybiera warunki początkowe upadku. Następnie opisano bardziej złożony model, tj. kinematykę robota, w którym ruch chwytaka może być kontrolowany poprzez użytkownika. Na koniec pokazano symulację dynamiki suwakowego mechanizmu korbowego w czasie rzeczywistym. Tezą pracy jest wykazanie, że integracja symulacji wielobryłowej z możliwościami Rzeczywistości Poszerzonej (AR) posiada ogromne walory dydaktyczne i stanowi pomoc w zadaniach międzyzespołowego projektowania.

In the era of information revolution we are communicating via the web. Reflections, thoughts and information are transmitted by building up the language of augmented reality. In communication networks, while leading a chat, we are also influenced by advertisements. It is a kind of multiple contact with the network of friends, strangers, journalists and advertising agents. Symbols and patterns transmitted by tradition are given their virtual dimension, their universal archetypes adjust their character to the present. The Modern Man, a network user, tries to use the new tool – the computer – more efficiently. The Internet network is often compared to the extension of the human neural system. The computer as a medium of art was used to create an additional space - the virtual reality. It showed how interesting spaces can be created by combining art and technology. The combination of the human specificity of contact, language, and new technology creates tremendous opportunities and threats. Transhumanism is a possibility in which we would seek a symbiosis between the man and technology, so as not to create a conflict between the biological body and its electronic contact networks. The semantics of the city, despite of its changing nature, may have human-specific qualities, but its media expression may allow for incomparably richer network of contacts.

This article discusses the role that new digital technologies play on conservation-restoration of fragmentary artefacts. Above all, the use of these tools is essential in case the artefacts have lost the formal unity and reach us without documentation concerning their original position, as in the case of the Roman frescoes from Sybaris, object of this study. The creation of virtual models proves as fundamental for the material and formal recomposition of the artefacts, especially in the creation of a new support and display choices. This last aspect required an analysis on the effects that virtual reconstructions and augmented reality have on visitors.
