Improving Depth Perception in Immersive Media Devices by Addressing Vergence-Accommodation Conflict.

Recently, immersive media devices have seen a boost in popularity. However, many problems still remain. Depth perception is a crucial part of how humans behave and interact with their environment. Convergence and accommodation are two physiological mechanisms that provide important depth cues. However, when humans are immersed in virtual environments, they experience a mismatch between these cues. This mismatch causes users to feel discomfort while also hindering their ability to fully perceive object distances. To address the conflict, we have developed a technique that encompasses inverse blurring into immersive media devices. For the inverse blurring, we utilize the classical Wiener deconvolution approach by proposing a novel technique that is applied without the need for an eye-tracker and implemented in a commercial immersive media device. The technique's ability to compensate for the vergence-accommodation conflict was verified through two user studies aimed at reaching and spatial awareness, respectively. The two studies yielded a statistically significant 36% and 48% error reduction in user performance to estimate distances, respectively. Overall, the work done demonstrates how visual stimuli can be modified to allow users to achieve a more natural perception and interaction with the virtual environment.

Perfumed platforms, or the common scents of post-Fordism

ABSTRACT In this paper, I look at the relationship between human olfaction, digital platforms, and everyday media practices in contemporary capitalist contexts. In the first section, I map what I describe as interfaced anosmia, or the absence of smell from mundane media devices. This absence is especially glaring given how olfaction uniquely lends itself to certain mediated forms of affective modulation. In the second section, I look at the platformization of the luxury fragrance industry, across three sites of analysis to reveal how, despite the conditions of interfaced anosmia, smell has already been shaped on and by platforms.

Effects of Media Device Use on Executive Function Difficulties of Children

Dry Needling Effects of the Upper Trapezius Muscle on the Angles and Range of Motion of the Neck in Individuals with Forward Head Posture

Introduction: Forward head posture (FHP) is one of the most common positional deviations. Frequent users often exhibit incorrect posture because of the rising popularity of media devices, such as smartphones and computers. This posture leads to changes in muscle activity in cervical flexion and extension. It is defined by hyperextension of the upper cervical vertebrae and forward translation of the cervical vertebrae. This study evaluates the effect of dry needles as a new method in the upper trapezius muscle on the neck’s angles and range of motion (ROM) in individuals with FHP
 Materials and Methods: In this quasi-experimental interventional study, 18 women with FHP underwent a dry needle session. The photogrammetry of the cranio-vertebral angle measured the degree of FHP. Visual analog scale (VAS), pain pressure threshold (PPT), cranio-vertebral angle (CVA) and cranio-horizontal angles (CHA), ROM, scapular index (SI), and forward shoulder translation (FST) were assessed before and after the intervention.
 Results: The results demonstrated that after the intervention, right and left PPT, flexion, and proper neck rotation, right and left SI, CVA, and CHA were significantly improved (P<0.05).
 Conclusion: The results showed that one session of dry needling with stretching exercises intervention could improve PPT, ROM, SI, CVA, and CHA and consequently improve FHP.

CREATIVE PROCESSES OF EMOTIONAL IMAGES: THE EFFECTS OF ASPECT RATIO ON THE EMOTIONAL AND AESTHETIC PROPERTIES OF IMAGES

Proportions are one of the primary components of successful image composition during the visual art creation process, which, in turn, is determinant of the variety of effects of images on the viewer, including emotional reactions, attention, and aesthetic preference. The importance of image width and height ratio is especially visible in the current trend to adopt the widest possible screens in a variety of modern creative media applications: photo, video, computer games, etc. In the present study emotional and aesthetic evaluations of the three most popular aspect ratios that are used in digital media devices were compared. This was achieved by assessing emotional arousal and valence ratings together with the interest and appeal evaluations of realistic photos presented in 4:3, 16:9, and 21:9 aspect ratios. The results demonstrated that the widest images did not have an inherent advantage – photos presented in the mid-wide aspect ratio of 16:9 could be considered as more effective, because they were rated as evoking the most positive emotional reactions and as the most liked pictures. This demonstrated that single design features can have an independent emotional effect, which needs to be considered in visual design aiming to evoke emotional reactions to the viewer.

Familial context influences media usage in 0- to 4-year old children.

The use of digital media (e.g., smartphones, tablets, etc.) and the Internet have become omnipresent for every age group and are part of children's and parents' everyday life. Focusing on young children, the availability of media devices, their use as well as associated problems (e.g., in social, emotional and motor development) have increased in recent years. Of particular interest for prevention of these problems in early childhood is the relationship between the familial context (parental digital media use, Problematic Internet Use, school graduation, presence of siblings) and the digital media use of infants and toddlers. The present study's goal was to describe media usage in 0-4-year-old children and to identify the potential relationship between familial context factors and child media usage. The sample included N = 3,035 children aged 0 to 3;11 years (M = 17.37 months, SD = 13.68; 49.13% female). Recruitment took place within the framework of a restandardization study for a German developmental test. The parents of the participants answered a questionnaire on socio-demographics, on child media use, and on parental media use. Questions on parental media use included the full version of the Short Compulsive Internet Use Scale (S-CIUS). Significant increases in media usage times with child age were identified, but no significant gender differences. A multiple regression analysis revealed that increasing maternal total media usage time, a higher parental S-CIUS score, lower school leaving certificate of both mother and father, and increasing child's age led to higher child media usage time. Having siblings diminished young children's media usage in this study. Having more than one child and having children aged over a year was associated with a higher parental S-CIUS score. Family factors such as maternal media use time, Problematic Internet Use and lower school graduation are significantly associated with young children's digital media use. Parents should be aware of their personal influence on their children's media use which might be due their role in terms of model learning.

The mediating effect of after-midnight use of digital media devices on the association of internet-related addictive behavior and insomnia in adolescents.

There is evidence that overexposure to digital media devices (DMD) can not only lead to addictive patterns of internet use, but also cause insomnia symptoms. The aim of this cross-sectional study among adolescents is to provide an estimate of the prevalence of sleep impairments and to explore the mediating role of after-midnight use of DMD between internet-related addictive behavior (IRAB) and insomnia. 2,712 school students from Styrian schools participated in a population-representative online survey in a supervised school setting in spring 2022. School students were screened using established and validated scales. Data analysis was carried out using multiple imputation, linear multilevel regression and mediation analysis. Prevalence estimation indicates high proportions of clinically relevant moderate [12.6% (11.3%; 14.1%)] and severe [3.6% (2.9%; 4.4%)] insomnia, with an additional 30.6% (29.0%; 32.2%) at subthreshold level. DMD are typically used after midnight an average of 1.66 (1.58; 1.75) evenings with subsequent school day per school week. Linear multilevel regression analysis shows significant associations for sleep disparities as outcome variable e.g., with generalized anxiety [b = 0.329 (0.287; 0.371)], after-midnight use of DMD [b = 0.470 (0.369; 0.572)] and IRAB [b = 0.131 (0.097; 0.165)]. Mediation analysis shows a mediated proportion of 18.2% (13.0%; 25.0%) of the association of IRAB and insomnia by after-midnight use of DMD [Indirect effect: b = 0.032 (0.023; 0.040), direct effect: b = 0.127 (0.083; 0.170)]. Although the cross-sectional nature of this study limits causal inference, the results indicate a need for policies, which are already in preparation in Styria as part of a respective action plan.

A Study on Media Literacy Use in School-Age Children with Language Disorder

They should be provided with new means of communication that emerge with the changing times. They should be able to recognize the advantages of the features of different media so that they can use the media usefully. The author believes that the effective and appropriate use of media literacy for elementary school students with disabilities will result in a positive impact. Therefore, this study aims to analyze the actual level of media literacy among School-age language disorder with disabilities and explore ways to promote it in a therapeutic aspect. Of the 40 people, 4 who did not respond appropriately were excluded, resulting in 36 people. In order to find out the status of media literacy use by speech rehabilitation workers currently working in language clinical sites, an online survey using Google Docs and a paper questionnaire were administered to the subjects. For the purpose of the study, ‘A survey on the use of media literacy by school-age children with language disorder’, the purpose of this study, the direction of data use, and how to complete the questionnaire were explained. We investigated the status and status of media use among school-age children with language disorder. The media used by the target children for more than 3 hours were games, animation, and Youtube. Among media outlets, it can be seen that SNS usage time is less than 2hours. And it was found that the target children were using all media, including TV, Game, Animation, Youtube, SNS, Movie/Drama, and Internet portal search. School-age children with language disorder had excellent use skills related to media devices, such as searching task-related keywords, grasping various contents, and finding task information. On the other hand, the subjects showed a low ability to use online information to evaluate its rationality and fairness. Lastly, all of the target children had low scores on questions related to media production ability. In particular, by understanding the current status of school-age media literacy content, it will be possible to identify the advantages of the characteristics of various media and apply them usefully in treatment.

Technological Immersion and Delegation to Virtual Agents

Interacting with virtual agents in immersive settings is becoming increasingly common thanks to the proliferation of dedicated media devices, such as consumer-grade virtual and augmented reality headsets. These technologies offer many advantages, e.g., in terms of presence and engagement, and can impact user behavior and attitudes toward virtual agents. Recognizing and understanding these effects is essential, especially in critical contexts involving the delegation of high-stake decisions to virtual agents. This article presents two experiments that explore users’ delegatory behavior toward virtual agents experienced via different media devices that vary in their technological immersion, i.e., a device’s technical capacity to deliver immersive experiences. The experiments’ results suggest that technological immersion is not a significant factor in users’ delegation decisions. Thus, for virtual agents designed to carry out critical tasks, developers may focus on other relevant factors, such as agents’ trustworthiness or performance.

Graphene nanoplatelets/Li-Mg-Sm spinel ferrite nanocomposites with improved dielectric and magnetic properties

This study aims to present Li0.2Mg0.6Sm0.03Fe2.17O4/Graphene nanoplatelets [LMSF/GNPs] composites prepared via SGAC route. X-ray diffraction study vindicated the pure spinel matrix and found that crystallite size (D) showed decreasing behavior with the substitution of GNPs in the LMSF lattice. Raman analysis was employed to study the molecular vibrational bands and, also verified the spinel structure along with the presence of GNPs. The dielectric constant was exponentially decreased up to 100 kHz frequency and then obtained constant behavior. However, the minimum dielectric tangent loss was also reduced with increasing frequency. The magnetic properties showed that saturation magnetization was reduced from 89.74 to 49.96 emu/g by an increasing GNPs concentration and the microwave operating frequency revealed a similar trend as saturation magnetization. Hence, based on LMSF/GNPs composites dielectric and magnetic behavior, LMSF/GNP composites are promising materials in applications related to high frequency and recording and storing media devices.

ОПРЕДЕЛЕНИЕ РЕЖИМОВ УЛЬТРАЗВУКОВОЙ КАВИТАЦИОННОЙ ОБРАБОТКИ МОТОРНОГО ТОПЛИВА

The article considers an example of ultrasonic cavitation created by a piezoelectric emitter. To identify the modes of ultrasonic cavitation treatment, the Qsonica sonicators Q-700 laboratory unit was used. The aim of the work is to determine the modes of ultrasonic treatment of motor fuel to create a cavitation region. Cavitation areas were determined by the area of destruction of aluminum foil samples, 0.008-0.009 mm thick. A sheet of aluminum foil was placed in the test medium parallel and perpendicular to the tip at different distances h, l. In order to identify the intensity of the resulting cavitation, cavitation noise was isolated from the signal of a hydrophone immersed in motor fuel at different distances from the radiator and connected to a multimeter model UT61E. The intensity of cavitation was estimated by the change in the resistance of the medium, R. The following types of motor fuel were used for processing: commercial diesel fuel, biodiesel based on ginger oil, mixed diesel fuel (containing 20% biodiesel). After the study, the foil was dried and the area of destruction was determined. It has been established that the following parameters influence the creation of cavitation – the distance from the radiating surface, intensity, amplitude and time of ultrasonic treatment of the sample.f= f (l, h, I, A, t). Four cavitation areas are defined: the area of active or optimal cavitation, the area of the beginning of cavitation, the area of incipient cavitation, the area of absence of cavitation. Depending on the amplitude and intensity, 6 operating modes are highlighted. It is established that the processing of the used motor fuel should be carried out on the 3 cavitation mode of operation (A =21-40%, I= 12.5-24.8 W / cm2) of the laboratory installation in the used technological volume or in larger volumes with reflective surfaces. It has been found that the cavitation noise in biodiesel is lower than in diesel fuel, since it is more viscous. In viscous liquids, cavitation is less developed and, consequently, the ultrasound absorption coefficient is lower for them. In this regard, it is necessary to design devices for media with a higher viscosity based on the optimal distance from the radiator to the bottom.

Association between media use and poor sleep quality among senior high school students: a cross-sectional study.

Background : Poor sleep quality (PSQ) is an increasing health problem among adolescents. Mobile phones and portable media devices have become a part of children's lives and may affect their sleep duration and quality. This study aimed to explore the prevalence of PSQ and identify the association between media use and PSQ among adolescents studying in high school grades 10-12. Methods: This cross-sectional study was conducted in central Thailand. A multi-stage sampling technique was used to enroll 777 adolescents from eight schools from August to October 2016. The research instruments comprised factors of demographics and consumption behaviors and the Pittsburgh Sleep Quality Index questionnaire. Multivariable logistic regression was used to calculate adjusted odds ratios (OR adj) and 95% confidence intervals (CI). Results: Prevalence of PSQ was 56.24%. The study subjects were mostly 16-17 years old (67.82%) and female (70.39%). Multivariable logistic regression, after controlling for possible confounders, revealed an increased odds of PSQ among those who used a social media device (OR=1.34, 95%CI=0.97-1.87), and showed a higher proportion of social media use in the PSQ group. Conclusion: A surveillance system to detect media use and PSQ should be conducted accompanied by knowledge sharing on media use among parents, teachers and adolescents. To determine causal relationships, further longitudinal studies will be required to test the association between media users and PSQ. This study may also provide some implications for health promotion on sleep quality of senior high school students.

Association of forward head posture with neck pain, cervicogenic headache, neuropathy, and neck mobility among university students: a cross-sectional study

Background: With the rising popularity of media devices, frequent users often exhibit poor habitual neck posture and suffer from a forward head deformity that may lead to neck and upper limb dysfunctions. Objective: To determine the association of forward head posture (FHP), neck pain, cervicogenic headache, neuropathy, and neck mobility among university students. Methods: An observational cross-sectional survey was conducted on students. There were four hundred participants in this study who were divided into two groups, Group 1's (G1) study hour was >6hrs and Group 2's (G2) study hour was <6hrs. The craniovertebral angle was measured by using a mobile app Photogrammetry Maneuver to evaluate head neck alignment. A digital camera of 12 megapascals was placed approximately 5 feet away from the participant. The camera's height was adjusted parallel to the participant's shoulder level, and they were asked to stand in their anatomical posture barefooted. Outcomes were measured as headache, local tenderness, neuropathy and range of motion associated with FHP. Data was collected through questionnaire and analyzed by using SPSS version 23. Results: There was significant association of duration of study with forward head posture (P<0.05). A strong positive correlation was found between forward head posture neck pain (r=0.78), cervicogenic headache (r=0.54), and neuropathy (r=0.29). Students also presented with decreased cervical range of motion. Conclusion: Students with prolonged study hours suffered more from forward head posture, neck pain, headache, hypomobility and neuropathy as compared to students with less study duration.
