    Opis:
    Virtual reality and the digital architectural representations of buildings that exist in the cyber realm are gathering more and more users as their platforms develop spaces better suited for the virtual human. Design of sites and interiors is being carried out by both experienced creators and those completely lacking skill in spatial creativity. Research was conducted during the course of two record gathering sessions lasting two weeks each, one at the beginning of February in the year 2020, the other at the end of the year in the last two weeks of the month of November 2020. Information was gathered about the population status of the most visited worlds at those times, as well as their specificity in architectural design traits. Comparison of the data showed that humans who attend online social gatherings and interactions in virtual reality worlds shifted their favor from median traits to those representing more high-end quality at the end of the year. Demographics show a rise in the amount of users aged between 6-10, and 21-35, in comparison to that of the beginning of 2020 where the dominant age group was between 16 and 21 years old. The global lockdown due to the pandemic attracted people from the home office generation who preferred architectural spaces of higher quality, larger and more complex floor plans, and spatial representations of high-rise residential, nightlife and fictional spaces for virtual human to human socializing and interaction.

    Opis:
    As academic conferences have become an indispensable part of contemporary science, providing researchers with an opportunity to present the results of recent investigations, become familiar with the studies of other scientists, and build and expand a network for future collaborations, this paper aims at examining Algerian researchers' perceptions of virtual academic conferences with regard the scientifc requirements of postgraduate students earning the required credits for their theses' defence and associate faculty members seeking promotion in their career. To this end, a questionnaire adapted from the relevant literature was compiled and sent to various Algerian researchers in the EFL field via their professional emails, with 40 replies being received. Data was analysed using numerals and percentage for closed items of the questionnaire, and thematic analysis for open-ended questions. Results of the study showed that the majority of participants are positive about virtual conferences, despite the technical challenges mainly associated with Internet accessibility and the decline in social interaction. The study concludes with a set of recommendations to raise stakeholders' awareness of technology support and future improvements to meet participants' needs.

    Opis:
    This work addresses the problem of difficulties in classical interpretation of combination tones as non- linear distortions. One of the basic problems of such an interpretation is to point out the sources of these distortions. Besides, these kinds of distortions have numerous “anomalies” which are difficult to explain on the grounds of physics or physiology. The aim of the model presented in this paper is to show that combination tones phenomenon can be explained as an effect of central mechanisms. Most of existing theories of pitch perception focus mainly on virtual pitch perception and do not take into account com- bination tones as an element of the same mechanism. The proposed model of central auditory processing for pitch perception allows one to interpret in a coherent way both virtual pitches and combination tones phenomena. This model is of a demonstrative nature and gives an introduction to more advanced model. It belongs to the class of spectral models and it will be shown that such a model can be in a simple way extended to spectral – time model which is partially consistent with autocorrelation models.

    Opis:
    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.

    Opis:
    After decades of research, technological development as well as few discouraging setbacks, virtual reality (VR) appears to be on the cusp of its settled adoption. The incorporation of VR technology into the palette of everyday communication media is not only exciting for filmmakers and game designers, but also for every manner of storytellers: documentarians, journalists, educators, scientists – all professions involved in clarifying surrounding us reality and communicating about it. They all discovered that social change can be valuably stimulated by development of new technology – technology that serves in the same time as a classic medium to communicate and spread this news around. Considering the factors enabling us to capture and disseminate “a true story” in a highly captivating, immersive way (which previously has been preserved exclusively for entertainment and commercial productions), we should mention at least 3 crucial elements: technological innovation, psychological evolution of the viewer, application of VR beyond storytelling. The first two factors mutually interact and play off each other in terms of the changing threshold of perceptual tolerance as well as rising needs of the new spectator. The first part of this paper deals with the interdependency of these two elements. Structured conclusions will be enumerated as a practical reference for VR storytelling productions. The second part of the paper will deal with the third element enumerating the most inspiring cases from recent years – eye-openers for instigating social change, adding value and promoting wellbeing via VR technology. The engagement of VR in social change, innovation and nonfiction storytelling introduced the VR technology within the current media palette. It not only changes the nature of storytelling about reality, but fulfills the story that our reality builds.

    The dynamic development of virtual reality technics opened new possibilities of creating visual, audial and audiovisual moving pictures. VR is coming and invaiding XXIst century cinema. There is a grand challenge for filmmakers imagination: show delivering vision of reality or so-called reality made without using real physical objects. Are we really prepared for this technological revolution? Hendrykowski’s paper poses certain crucial questions connected with that change in making movies. Among them: ambigous nature of digital sign, possible regions of spectator’s new experiences, symbolic function of digital images and deep transformation of category od aesthetics in expanding world of multimedia.

    Opis:
    The head-related transfer function (HRTF) is dependent on the position of the sound source (both direction and distance) and is also affected by individual anatomical parameters. Individualized HRTFs have been shown to affect the perception of sound direction, but have not been considered in distance perception. This work aims to discover, by means of psychoacoustic experiments for a virtual reproduction system through a pair of in-ear headphones, the effect of individualized HRTF on auditory distance perception for a nearby sound source. The individualized HRTFs of six subjects and the non-individualized HRTFs of a mannequin at seven distances between 0.2 and 1.0 m and five lateral azimuths between 45° and 135° in the horizontal plane were processed with white noise to generate binaural signals. Further, the individualized and non-individualized HRTFs were used in the auditory distance perception experiments. Results of distance perception show that the variance of distance perception results among subjects is significant, the reason could be the stimuli are lack of dynamic cue and early reflections, or the audi tory difference of distance perception among subjects. However, via the analyses of mean slope of perceptual distance and correlation between the perceptual and real distance, we find that the individualized HRTF cue has insignificant influence on distance perception.

    Opis:
    Nulltopia is disjunction in space, the non-space between one space and another. Such disjunction becomes important in the ontology of imaginary worlds, whose thresholds are not fully traversable. Some knowledge and some exigencies transfer across the boundaries of an image, but some do not, remaining asymmetrically bound, extant only on one side – potentiating scenarios like starving while eating Minecraft cookies. This theoretical study presents an exercise in the metaphysics of digital games, defining nulltopia in reference to dreams, the theatrical proscenium, vehicle windows, video screens, loudspeakers, and interactive consoles; and contextualizing nulltopia relative to immersion. Developing from a syncretic combination of movement and depiction, the video screen extends a technology of imagination that already existed in component forms. Partially separating slow reality from fast imaginary, nulltopia affords both discourse and addiction to the ‘etiolated actual’, in contrast to an imagined, perfectly immersive, ‘society without screens’,the bounds of whose world become imperceptible.

    Opis:
    The paper addresses the matter of differences of aesthetic judgment by examining Shake-speare’s Tempest through the Thomistic understanding of substance and of beauty. It seeks principally to explore three elements of aesthetic inquiry: (1) what characterizes the subject who perceives beauty? (2) what characterizes the object of aesthetic experi-ence? and (3) how do aesthetic judgments differ from sensual perceptions? The Tem-pest serves as particularly fruitful territory for such exploration in virtue of the persons of Miranda and Caliban, who by the limitations of their experience delineate the generic borders, the degrees of virtual quantum excellence, which characterize the beautiful object. Their education at the hand of Prospero likewise elucidates somewhat the proc-ess of aesthetic training.

    Opis:
    Wirtualna przestrzeń zbudowana z voxeli, której składniki programujemy, to więcej niż środowisko gier komputerowych. Cyfrowa reprezentacja, o której Mitchell, jeszcze w latach dziewięćdziesiątych ubiegłego wieku, pisał przez pryzmat fotografii, dociera dziś do sedna zainteresowań architektury. Zapewnia jej, po raz pierwszy w historii, skuteczny aparat przekazu. Być może - przenosi do grona uprzywilejowanych sztuk jednostopniowych, gdzie efekt dostępny jest natychmiast - w chwili aktu twórczego. Nowa metoda otworzyła nowe możliwości. Z jednej strony udostępniła poligon do prób, z drugiej - alternatywne środowisko kreacji architektonicznej. Przestrzeń architektoniczna reprezentowana jest dziś przy pomocy medium cyfrowego, przez co uzyskuje cechy, które wypunktował Manovich. Percepcja przestała być funkcją eksploracji. Chwilowe stany zmieniają się dynamicznie, zależnie od zmierzonych w otoczeniu parametrów i życzeń użytkownika, czyli w wyniku interakcji. Kształtowanie zmiennego otoczenia wymaga użycia narzędzi programistycznych. Nie jest już kreowaniem docelowych stanów, lecz reguł ich zmienności. Granice między rzeczywistością realną, wirtualną i informacyjną ulegają zatarciu dzięki swobodnemu tłumaczeniu, natychmiastowemu przesyłaniu na odległość, oraz dostarczaniu zmysłom sygnałów tworzonych przez niezauważalne, cyfrowo sterowane, przenośne aparaty. Stopienie cyfrowej reprezentacji modelu komputerowego, jego projekcji, rzeczywistych materiałów, cyfrowej produkcji oraz sensorów, urządzeń komunikacyjnych i mechanizmów sterowanych komputerowo, pozwala mówić o ciągłym, przestrzennym środowisku informacyjnym, tworzącym medium.
    Virtual space built of voxels, the components of which we program, is more that the environment of computer games. Digital representation, about which Mitchell was already writing in the 1990s, though from the perspective of photography, today has become an essential factor in architecture, providing, for the first time in history, an effective transmission device. It may have moved it to the privileged group of one-stage art forms, in which the effect is accessible immediately, at the moment of the creative act. The new method opened up new possibilities. On the one hand, it provided the ground for trials, on the other - an alternative environment of architectural creation. Architectural space is represented today through a digital medium, thus achieving features enumerated by Manovich. Its numerical structure, modularity and automaticity result directly from the binary form of the data. Perception is no longer a function of exploration. Momentary states change dynamically, depending on the parameters of the surrounding environment and the wishes of the user, in other words, as a result of interaction. Shaping a changing environment requires the use of programming tools. It is no longer the creating of target states, but the rules of their variability. The boundaries between real, virtual and information reality are blurred due to free translation, immediate remote transfer, and the delivery to the senses of signals created by imperceptible, digitally controlled, portable devices. The merging of the digital representation of the computer model, its projection, actual materials, digital production and sensors, communication devices, and computer-controlled mechanisms, makes it possible to talk about a continuous spatial information environment that creates the medium of contemporary architecture.

    Opis:
    Simultaneous perception of audio and visual stimuli often causes concealment or misrepresentation of information actually contained in these stimuli. Such effects are called the "image proximity effect" or the "ventriloquism effect" in the literature. Until recently, most research carried out to understand their nature was based on subjective assessments. The authors of this paper propose a methodology based on both subjective and objectively retrieved data. In this methodology, objective data reflect the screen areas that attract most attention. The data were collected and processed by an eye-gaze tracking system. To support the proposed methodology, two series of experiments were conducted – one with a commercial eye-gaze tracking system Tobii T60, and another with the Cyber-Eye system developed at the Multimedia Systems Department of the Gdańsk University of Technology. In most cases, the visual-auditory stimuli were presented using a 3D video. It was found that the eye-gaze tracking system did objectivize the results of experiments. Moreover, the tests revealed a strong correlation between the localization of a visual stimulus on which a participant’s gaze focused and the value of the "image proximity effect". It was also proved that gaze tracking may be useful in experiments which aim at evaluation of the proximity effect when presented visual stimuli are stereoscopic.

    The article is an interpretation of Esse by Czesław Miłosz and a fragment of a book by Dorota Masłowska Darling, I killed our cats (Kochanie zabiłam nasze koty). It presents similarities and differences in the perception of the world and people which partially stem from generational, technological, and cultural changes. Travelling by metro is the comparative area which the authors use as the context for reflection on interpersonal relations and cognitive possibilities. The background for the juxtaposition are remarks of George Simmel on the behaviour of the citizens of metropolises. For both works, they are a valuable, yet different, reference point.
