The paper presents an interdisciplinary approach to the treatment of the FormaViva collection of wooden sculptures exhibited outdoors in a natural environment near the Božidar Jakac Art Museum in Kostanjevica na Krki in Slovenia. The study focuses on 3D graphic representations of sculptures created with photogrammetry and 3D modelling. The results are photorealistic renderings, interactive presentations, 3D printed reproductions, jewellery, and interpretive animations. The research results show that graphic documentation techniques on 3D models allow for a more detailed investigation of the original structural identity of the sculpture. By incorporating 3D and interactive technologies, we are expanding the usability of cultural heritage objects. By using interpretive techniques that have led to jewellery and interpretive animations in our research, we not only breathe new life into the sculptures, but also enrich the stories of the sculptures with our own experiences of the sculptural work.

Mobile technology offers new opportunities to enhance the visitor experience in museums. Mobile serious games can support experiential learning with authentic exhibits in an authentic museum environment based on the contextual learning model with the interaction between the personal, socio-cultural, and physical context. In developing the game, we wondered whether it could appropriately motivate and engage different age groups in the museum experience with its challenges of different difficulty levels; whether a mobile game could, through its challenges interacting with the museum environment, prevent “head-down” behavior; and whether museum exhibits could be better recalled by visitors participating in a tour with a mobile game than in two other traditional tours (i.e., guided tours, tours with museum brochures). The results of the study showed that a tour with a mobile serious game with challenges of different difficulty levels is suitable for visitors of two target groups (i.e., families and students). Since each challenge encourages interaction with the museum environment, it could largely prevent “head-down” behavior. The results also show that a tour with appropriately planned multisensory challenges motivates visitors to actively engage with the museum environment, resulting in slightly better recall of exhibits compared to other tour types. The results of this study can help bring museums and the history they represent closer to digital generations, ¹ and popularize modern informal learning methods associated with incidental and experiential lifelong learning that can take place anytime, anywhere, and help achieve higher taxonomic knowledge levels.

The aim of the study was to determine the progress in the use of online classrooms, gather opinions on their functional use on computers or mobile devices, on user interface and its elements, work within online classrooms, and on the advantages and disadvantages of conducting examinations in online classrooms. The research involved students from various study programmes, including students of textile and clothing study programmes, and focused on analysing the use of Moodle online classrooms through the system’s built-in tools and student surveys. The results indicate that the number of users of online classrooms is increasing. Students access online classrooms via computers and, increasingly, via mobile devices. The overall appearance of online classrooms was assessed as appropriate on both computers and mobile devices, with some comments suggesting improvements in the personalisation of the dashboard and better visual organisation. Students were satisfied with the arrangement and accessibility of control elements on both types of devices and praised the typography used, while expressing less satisfaction with some of the icons representing certain functions. Remarks were also made regarding the unclear labelling of some functions or commands. The information displayed on both devices was considered visible, although its retrieval on mobile devices was perceived as time-consuming. Students reported becoming familiar with the online classroom quickly and appreciated their practicality. They were satisfied with the organisation of content by chapters. A smaller number of students uses the online classroom for exchanging opinions or group work, while they still prefer email communication for interaction with lecturers. Students praised the simplicity of submitting assignments via the online environment (esp. group assignments) and the opportunity to receive feedback from assessors. They did not encounter major difficulties when taking exams within the online classroom. They found the technical implementation straightforward, the information provided in the examination (quiz) environment useful, and the appearance of the exam interface pleasant. The findings of the study indicate the need for improvements primarily in the area of the user interface and in encouraging greater use of tools that enable direct communication among participants within online classrooms. It is also recommended that the faculty provide targeted professional training for academic and technical staff in the advanced functionalities of Moodle, promote the inclusion of interactive and collaborative learning activities, establish coherent pedagogical guidelines for online course design, systematically collect and apply user feedback, and encourage the use of digitally supported forms of teaching.

In recent decades, linear communication has largely been replaced by visual depictions that contain not only moving images but also sound, text and other (visible or invisible) data. It is therefore not surprising that video has become so popular, especially among young people. So-called multimedia communication is transmitted via a variety of media. Since there are many ways and means of transmission, we wanted to investigate how the type of encoding that allows efficient file reduction affects the characteristics of the video format. For this purpose, we encoded selected videos using the three most common encoding mechanisms H.264/AVC, MPEG-2 and H.265/HEVC at high and medium bitrate. The newly created video files were then uploaded to three popular platforms – Instagram, YouTube and Gmail. Changes in file size, colour gamut, frame and bitrate, resolution and other visually recognizable details are presented in the paper.

Wiener estimation is a widely used technique for the spectral reflectance reconstruction of colored objects. In our study the reflectance estimation of 3-channel images acquired using traditional RGB camera was compared with that of 6-channel images...
