GestureGPT: Toward Zero-Shot Free-Form Hand Gesture Understanding with Large Language Model Agents

Existing gesture interfaces only work with a fixed set of gestures defined either by interface designers or by users themselves, which introduces learning or demonstration efforts that diminish their naturalness. Humans, on the other hand, understand free-form gestures by synthesizing the gesture, context, experience, and common sense. In this way, the user does not need to learn, demonstrate, or associate gestures. We introduce GestureGPT, a free-form hand gesture understanding framework that mimics human gesture understanding procedures to enable a natural free-form gestural interface. Our framework leverages multiple Large Language Model agents to manage and synthesize gesture and context information, then infers the interaction intent by associating the gesture with an interface function. More specifically, our triple-agent framework includes a Gesture Description Agent that automatically segments and formulates natural language descriptions of hand poses and movements based on hand landmark coordinates. The description is deciphered by a Gesture Inference Agent through self-reasoning and querying about the interaction context (e.g., interaction history, gaze data), which is managed by a Context Management Agent. Following iterative exchanges, the Gesture Inference Agent discerns the user’s intent by grounding it to an interactive function. We validated our framework offline under two real-world scenarios: smart home control and online video streaming. The average zero-shot Top-1/Top-5 grounding accuracies are 44.79%/83.59% for smart home tasks and 37.50%/73.44% for video streaming tasks. We also provide an extensive discussion that includes rationale for model selection, generalizability, and future research directions for a practical system etc.

Findings revealed that lecturers significantly improved their basic skills in recording, editing, and website creation, achieving nearly 100% proficiency post-training. The Problems found that inadequate computer specifications (66.66%), slow internet connections (38.88%), and a lack of foundational computer knowledge (55.55%). These issues hindered effective practice, highlighting the need for better resources. The research also identified key motivational factors for lecturers, including access to fast, high-quality internet, the requirement for subject-specific teaching videos, and financial support for video production. These factors demonstrated a statistically significant correlation with lecturers' motivation to create and share educational content. Overall, the study underscores the importance of training and resource availability in fostering digital education and identifies specific barriers and motivators that can enhance lecturers' engagement with technology in teaching.

Nurses' adherence to ethical principles - A qualitative study.

Nursing is regulated by a set of professional standards. Whilst many forms of ethics apply to nursing, the biomedical ethical framework is common, involving autonomy, beneficence, non-maleficence and justice. In healthcare, nurses often encounter ethical dilemmas that require them to navigate conflicting ethical principles. However, how nurses adhere to these principles in such situations is unclear. To explore how registered nurses adhere to ethical principles when dealing with ethical dilemmas at work. A qualitative descriptive study design. Between August and December 2023, 21 registered nurses were recruited from a teaching hospital through purposive sampling. Data were collected through semi-structured in-person interviews or online video conferencing. Braun and Clarke's thematic analysis approach was employed to analyse the data. Interview participation was voluntary. Written consent was obtained before participation. Participants' real identities were replaced with pseudonyms. This study was approved by the SingHealth Centralised Institutional Review Board. The data analysis developed four major themes and 15 subthemes. The four major themes are "Addressing the dilemma," "Contemplating the principles and consequences," "Coordinating for well-informed, ethical decision," and "Self-reflecting and finding consolation." This study explains how nurses navigate and uphold ethical principles when caring for patients to the best of their ability. Fully adhering to ethical principles can be challenging for caring for actively dying patients. Further research can expound on nurses' experiences and adherence to ethical principles in complex clinical cases.

Influence of parental mediation and social skills on adolescents' use of online video games for escapism: A cross-sectional study.

The widespread use of video games among adolescents has raised concerns about their impact on psychological and social development. This study aimed to assess the effects of different types of parental mediation on adolescents' tendency to use video games to avoid negative emotions and determine the relationship between adolescents' interpersonal skills and their reliance on online video games for escapism. Participants were 452 adolescents from 15 middle and high schools. Data on sociodemographic information, gaming habits, parental control of online gaming, interpersonal skills, and reasons for playing online games were also collected. Hierarchical multiple regression was used to analyze the data, with online video game escapism as the dependent variable. Results supported the study's hypothesis that both parental mediation and adolescent interpersonal skills significantly predict the use of online video games for escapism. Higher levels of parental monitoring were associated with a lower tendency of adolescents to use video games to escape negative emotions, while parental mediation supporting autonomy showed a similar but weaker protective effect. At the same time, parental monitoring was also found to be associated with lower interpersonal skills, notably higher impulsivity, narcissism, and stress in social situations. In addition, adolescents with higher levels of impulsivity were more likely to use video games for escapism. These findings highlight the importance of balanced parental involvement and the development of adolescents' social skills to mitigate the risks of problematic online gaming. Interventions should promote effective parental mediation strategies and enhance adolescents' interpersonal skills to reduce their tendency to use video games as a coping mechanism for real-life challenges. Effective parental mediation and improved interpersonal skills are critical for promoting healthier gaming habits and reducing adolescent escapism.

The Butterfly effect in the consumption of electric and hybrid cars: between utilitarianism and environmental awareness

In this study, we conducted an investigation aimed at understanding the consumption of hybrid or electric vehicles from utilitarian or substantive aspects. Employing a qualitative and exploratory approach grounded in culture and consumption studies, we adopted netnography as the method for data collection and analysis (Kozinets, 2006; 2019). Our focus was directed towards participation in an online community of electric car consumers, as well as the analysis of interactive chats and comments on online videos about hybrid cars. Surprisingly, our findings revealed that many consumers embark on their journey motivated by the financial benefits of electric cars, drawn by the promise of savings. However, over time, we identified an intriguing phenomenon that we termed the "butterfly effect": as consumers engage more deeply in the consumption experience and interact within the online community, there is a significant increase in environmental awareness. This finding suggests that sustainable automobile consumption transcends purely utilitarian considerations, incorporating values and environmental concerns. Interaction within the online community emerges as a crucial factor in this process, serving as a catalyst for a shift in perspective towards vehicle consumption. The exchange of information, experiences, and perspectives within this virtual environment appears to stimulate deeper reflection on the environmental ramifications of their consumption choices. Thus, this study offers significant insights into the dynamics of consumer behavior regarding sustainable vehicles, highlighting the importance of online interactions in promoting environmental awareness and the adoption of more sustainable consumption practices. Furthermore, it underscores the need for a more holistic approach to understanding consumer motivations and decision-making processes in this evolving landscape.

Reducing Ageism and Ableism with Brief Videos Providing Education about Aging and Disabilities and Exposure to Positive Intergenerational Contact.

Older adults living with a disability (LWD) face both ageism and ableism, but there are few interventions to address this significant and growing social problem. Drawing on the PEACE (Positive Education about Aging and Contact Experiences) Model, three online studies involved participants randomly assigned to watch four brief online videos providing education about aging and disability and exposure to positive contact between younger adults and older adults/older adults LWD (experimental condition) or videos about interior design (control condition). Studies 1 (community sample) and 2 (university sample) included an immediate post-test whereas Study 3 (2 university samples) additionally included a pre-test and delayed post-test. Experimental condition (vs. control) participants reported greater agreement with older adults LWD as contributors to society (immediate post-test in Studies 1 and 2; immediate and delayed post-test in Study 3), lesser (greater) endorsement of negative (positive) stereotypes of older adults and older adults LWD, lesser agreement with older adults LWD as burdensome, lesser intergenerational tension with older adults (immediate post-test in Study 2; immediate and delayed post-test in Study 3), and greater openness to careers working with older adults and older adults LWD (immediate and delayed post-test in Study 3). Brief online interventions that involve education about aging and disabilities as well as exposure to positive intergenerational contact can be an effective means of reducing ableism and ageism toward older adults and older adults LWD.

How does OTT social viewing relieve pandemic-related depressive symptoms? Investigating the moderated mediation model of social connectedness and network types

ABSTRACT After the outbreak of COVID-19, people have lacked offline social opportunities and had to focus their energy on online social activities. While some researchers have proposed that both anxiety and depression have increased significantly during the COVID-19 pandemic, previous studies have provided evidence that people have mitigated negative emotions during the health crisis by using online services. In this manner, the pandemic-induced increase in online activity has significantly boosted global demand for online video services (Over-the-Top, OTT). OTT social viewing refers to the act of interacting with other users while simultaneously watching content through the social viewing service provided by OTT service providers. Drawing on the social compensation hypothesis and social capital theory, we surveyed people who experienced COVID-19-related depression and used Watch party, a key OTT social viewing service in Korea. The study reveals that while social media alone did not directly alleviate COVID-19-related depression, emotional stability was regained through building social connectedness via online activities. Furthermore, the study highlights that in OTT social viewing, the quality of interactions, rather than the quantity, was more crucial for forming social connectedness.

Examining English learning students’ experiences related to home language use in a Physical Science and Language Development classroom

Research suggests that by allowing English Learner (EL) students to use their home languages in science class, they can better express their thinking and build content knowledge through underlying crosslinguistic awareness between languages. However, EL students’ educational backgrounds and home languages are incredibly varied. In this case study, we employ grounded theory to explore students' perceptions of their experiences in the context of a Physical Science and Language Development class [10]. We use a phenomenological approach to describe how the students experience their home language within this model of a science and language development class. Observation data, online video assignments, and small group, semi-structured interviews were used to find themes related to experiences of using home language in science class. The findings indicate varied student perspectives on the use of their home languages in science class. Some students preferred to use class time to practice using English, while others found value in using their home languages to help better understand science concepts. Student ideologies regarding English-only or multilingual practices for EL students varied. The findings also indicated that providing an opportunity for EL students to use their home languages in an asynchronous online communication platform outside of class was an effective strategy to allow time for students to practice English during science class, yet provide an opportunity to translate between home languages and English.

Inter-rater Reliability of Pressure Pain Threshold Between Experienced and Novice Examiners: A Case Study of 2 Educational Approaches.

Pressure Pain Threshold (PPT) is used to objectively assess pain in clinical settings and is a recommended part of physical therapist education. An individual who is experienced in administering PPT will frequently train a student on the technique; however, optimal educational approaches for this instruction have not yet been identified. Therefore, the purpose of this case report is to describe 2 educational approaches (unstructured lecture and structured feedback with clinical relevance) in training 2 separate cohorts of Doctor of Physical Therapy students in PPT. The primary outcome of interest was the inter-rater reliability of PPT between an experienced and novice examiner. Cohort 1 (n = 37) received a traditional lecture approach consisting of watching a prerecorded video online, an in-person lecture with demonstration of the technique, and time to practice. Cohort 2 (n = 34) received the prerecorded video online and lecture with demonstration; however, key additions included a clinical relevance discussion along with structured peer-to-peer and instructor-to-student feedback using a competency-based checklist. PPT was assessed by each student (novice examiner) and one instructor (experienced examiner). Inter-rater reliability of PPT between a novice and experienced examiner was evaluated. Inter-rater reliability improved from poor/moderate (intraclass correlation coefficient low back = 0.46 [0.16-0.68], quadriceps = 0.54 [0.26-0.73]) to good (low back = 0.84 [0.67-0.92], quadriceps = 0.90 [0.79-0.95]) after the addition of structured feedback. Structured feedback from peers and instructors may be useful when learning PPT and improving inter-rater reliability, which has implications for training students within a laboratory or classroom. However, this case study would need to be replicated in an experimental design to examine the effects of varying types of feedback on learning outcomes.

Rainbow within and beyond: A qualitative study on the experiences of lesbian, gay, bisexual, and transgender staff nurses in the Philippine hospital settings.

An individual's sexual orientation plays a fundamental role in their self-identity, relationships, and health. Years have shown both progressive and regressive responses to the LGBT community's social acceptance, particularly observable in various areas. Yet existing literature overlooks the Filipino healthcare settings, particularly with lesbian, gay, bisexual, and transgender (LGBT) staff nurses. Exploring their perspectives and experiences, whether challenges or successes, is crucial for gaining insights into occupational matters, workplace dynamics, and policy development. The research aimed to explore the lived experiences of LGBT staff nurses in the hospital settings. Husserl's Transcendental Phenomenology research design was utilized in this study. Participants included LGBT staff nurses with at least a year of experience at any hospital department. Individualized unstructured interviews were conducted with three participants interviewed face-to-face and five through online video conferencing platforms from March to April 2024. All interviews were transcribed, coded, themed, and analyzed using Colaizzi's approach. Data saturation was achieved with eight participants. Seven themes emerged, including: Recognizing Gender Stereotypes, Optimizing Nursing Care, Yearning for Acceptance, Generating Meaningful Relationships, Battling Heteronormative Gender Norms, Inspiring Potentials beyond Gender and Profession, and Valuing the Progress of LGBT Inclusivity. The study revealed that LGBT staff nurses had multifaceted experiences with patients, colleagues, and superiors in the hospital settings as their workplace. They faced gender stereotyping and battled against limits on expression but fought to defend their authentic identities. They built relationships with colleagues and strived to be defined beyond societal perceptions. As they yearn for amplified LGBT acceptance in the workplace and society, they expressed gratitude for progress towards acceptance of the LGBT community.

How To Tame a Toxic Player? A Systematic Literature Review on Intervention Systems for Toxic Behaviors in Online Video Games

Toxic behavior is known to cause harm in online games. Players regularly experience negative, hateful, or inappropriate behavior. Interventions, such as banning players or chat message filtering, can help combat toxicity but are not widely available or even comprehensively studied regarding their approaches and evaluations. We conducted a systematic literature review that provides insights into the current state of interventions literature, outlining their strengths and shortcomings. We identified 36 interventions and qualitatively analyzed their approaches. We describe the types of toxicity being addressed, the entities through which they act, the methods used by intervention systems, and how they are evaluated. Our results provide guidance for future interventions, outlining a design space based on known systems. Furthermore, our findings highlight gaps in the literature, e.g., a sparsity of empirical evaluations, and underexplored areas in the design space, enabling researchers to explore novel directions for future interventions.

You Do You[Tube]!The multifaceted roles of online video viewing in the lives of U.S. children

Guided by uses and gratifications theory, the current project invited parents (N = 358) to submit YouTube videos (N = 973) recently viewed by their children aged 0 to 8. Parents rated each video for its perceived impact on their child, while coders evaluated each video for its content. Results indicated that in-depth educational lessons were rare in these videos, and potentially harmful depictions were common (e.g., physical aggression). Despite these issues, parents reported that these videos often evoked children's joy, fostered social bonding, and allowed children to explore niche interests. Some patterns varied by age, such that older (vs. younger) children viewed fewer educational videos, and they experienced fewer emotional gratifications from viewing. However, older children also viewed more videos with peers, and parents reported that those experiences facilitated peer bonding. Collectively, these findings replicate some concerning patterns found in previous research while also hinting at positive aspects of YouTube exposure that are neglected in discourse about children's experiences online.

User Datagram Protocol Parametric Analysis for Maximum Transmission Unit in High-Definition Video Transmission for 1080p and 720p

This article analyses the parametric used for Maximum Transmission Unit (MTU) in User Datagram Protocol (UDP) for online video streaming based on 1080p HD video and 720p HD video. Using a one-to-one node network design, this article has offered an investigation of the performance of UDP in NS3. UDP experiences rather considerable packet losses during the simulation procedure by contrasting the pertinent performance indicators. The selection of the video streaming applications over UDP as an example relates the requirements for group video conferencing and the computation of packet sizes. Understanding the simulation's results can help network administrators deal with network problems involving video streaming, video conferencing, or any other applications that might be connected to the associated protocol.

Enhanced Dual-Layer Video Steganographic Approach: Enhancing Security and Imperceptibility

In a digital age where the role of digital information is continually expanding, the imperative to ensure secure communication and data protection has intensified. Steganography, a field that conceals sensitive information within apparently innocuous carriers like multimedia files, holds promise for achieving this goal. Recent times have seen a growing interest in video-based steganography, driven by the proliferation of videos online. However, a review has unveiled a noteworthy gap in efforts to increase the safety of video steganography employing the popular Least Significant Bit (LSB) process. LSB steganography is at risk to exploits that could jeopardize the confidentiality of the concealed message. In this research, we present a video steganographic solution achieved through the integration of advanced encryption algorithms and a dual approach involving randomized frame selection using the Fisher-Yates method and pixel selection utilizing the 8-directional technique. Additionally, we have devised an upgraded imperceptible video steganographic approach in the spatial domain, capitalizing on an XOR-based LSB substitution embedding approach. The outcomes underscore the effectiveness of our proposed methodology, revealing significant imperceptibility when compared to recent solutions, thereby reinforcing data security against unauthorized access. This comprehensive solution holds wide-ranging applications across various domains, providing heightened security and confidentiality for sensitive information. Notable applications include secure communications within intelligence agencies, safeguarding patient data in medical sciences, ensuring privacy in video surveillance, fortifying video transmission against errors and data breaches, securing business communications, preventing data leakage, and enhancing rights management for digital content.
