Analysing crowd- and screen-based exploration behaviour compared to HMD viewing in 360° videos

Introduction: Omnidirectional videos (ODV) have become increasingly relevant in multimedia research and applications. Most prior studies focused on viewing these videos with head-mounted displays (HMDs) in controlled lab environments, requiring complex setups and costly hardware. This limits the feasibility…

The influence of complex classroom noise on auditory selective attention

Recent efforts to mimic real-life situations in experiments aim to improve the ecological validity of research. Acoustically, this often involves using binaural reproduction to create realistic environments. While studies have shown that simplified acoustic presentations, such as white noise, affect…

Speaker-story mapping as a method to evaluate audiovisual scene analysis in a virtual classroom scenario

This study explores how audiovisual immersive virtual environments (IVEs) can assess cognitive performance in classroom-like settings, addressing limitations in simpler acoustic and visual representations. This study examines the potential of a test paradigm using speaker-story mapping, called “audiovisual…

Nonverbal dynamics in dyadic videoconferencing interaction : the role of video resolution and conversational quality

In this paper, we investigated the influence of video resolution and perceived conversational quality on nonverbal behaviors during dyadic videoconferencing (VC) conversations. We analyzed nonverbal behaviors at the individual and interpersonal level. At the individual level, we considered body motion,…

Assessing quality differences for 8K/UHD-2 and 4K/UHD-1 HDR video based on viewing distance

One of the elements influencing users’ perception of video quality is the viewing distance. Although TVs have grown in size and resolution, viewers’ watching behavior and living room conditions have not changed equally and therefore viewers sit at distances farther than optimal. This gives rise to the…

Systematische Analyse von genrespezifischen Videoaufnahmen am Beispiel von Theateraufzeichnungen : Automatisierung von Mehrkameraaufnahmen

In dieser Arbeit wird vorgestellt, wie Mehrkameraaufzeichnungen von Theateraufführungen in einer nicht-professionellen Umgebung vereinfacht durchgeführt und im Endergebnis verbessert werden können. Eine Produktionsmethode mit vier hochauflösenden Kameras wird vorgeschlagen. Die Totalen können mit feststehenden…

Introducing personas and scenarios to highlight older adults' perspectives on robot-mediated communication

Little is known about the expectations of older adults (60+ years old) in robot-mediated communication when leaving aside care-related activities. To bridge this gap, we carried out 30 semi-structured interviews with older adults to explore their experiences and expectations related to technology-mediated…

Cross-timescale experience evaluation framework for productive teaming

This paper presents the initial concept for an evaluation framework to systematically evaluate productive teaming (PT). We consider PT as adaptive human-machine interactions between human users and augmented technical production systems. Also, human-to-human communication as part of a hybrid team with…

Automatic camera selection, shot size, and video editing in theater multi-camera recordings

In a non-professional environment, multi-camera recordings of theater performances or other stage shows are difficult to realize, because amateurs are usually untrained in camera work and in using a vision mixing desk that mixes multiple cameras. This can be remedied by a production process with high-resolution…

Image appeal revisited : analysis, new dataset, and prediction models

There are more and more photographic images uploaded to social media platforms such as Instagram, Flickr, or Facebook on a daily basis. At the same time, attention and consumption for such images is high, with image views and liking as one of the success factors for users and driving forces for social…

Quality assessment of higher resolution images and videos with remote testing

In many research fields, human-annotated data plays an important role as it is used to accomplish a multitude of tasks. One such example is in the field of multimedia quality assessment where subjective annotations can be used to train or evaluate quality prediction models. Lab-based tests could be one…

Modeling of an automatic vision mixer with human characteristics for multi-camera theater recordings

A production process using high-resolution cameras can be used for multi-camera recordings of theater performances or other stage performances. One approach to automate the generation of suitable image cuts could be to focus on speaker changes so that the person who is speaking is shown in the generated…

Examining the auditory selective attention switch in a child-suited virtual reality classroom environment

The ability to focus ones attention in different acoustical environments has been thoroughly investigated in the past. However, recent technological advancements have made it possible to perform laboratory experiments in a more realistic manner. In order to investigate close-to-real-life scenarios, a…

Digital media in intergenerational communication: status quo and future scenarios for the grandparent-grandchild relationship

Communication technologies play an important role in maintaining the grandparent-grandchild (GP-GC) relationship. Based on Media Richness Theory, this study investigates the frequency of use (RQ1) and perceived quality (RQ2) of established media as well as the potential use of selected innovative media…

Differential effects of task-irrelevant monaural and binaural classroom scenarios on children's and adults' speech perception,…

Most studies investigating the effects of environmental noise on children’s cognitive performance examine the impact of monaural noise (i.e., same signal to both ears), oversimplifying multiple aspects of binaural hearing (i.e., adequately reproducing interaural differences and spatial information).…
