Construction and application of interactive platform of art design based on multimedia technology

Contemporary art design not only pursues the quality of the work itself, but also pays attention to the sensory aspects of people’s needs for art design. Traditional art design methods can be limited by time, space and other objective conditions, and often fail to achieve the designer’s expected effect, and visitors’ experience is not strong. The usage of multimedia technology in art and design can enrich its expression and enhance visitors’ experience. In order to increase the sense of interaction between the platform and users, multimedia technology is incorporated into the interactive art design platform generated by VR technology in this paper. This article combines multimedia technology with interactive technology to construct an interactive platform for art and design, and applies it to the display of Dunhuang murals. Through the analysis of user experience feedback, the effectiveness of art and design display and interaction is verified. Display and interact with Dunhuang murals as interactive platform applications. This test is to extract women’s clothing colors from the same tradition in different times in the color extraction exploration module of the interactive platform, so as to provide accurate information for displaying women’s clothing color changes and comparing interactions. The findings show that the platform is capable of extracting and recognizing the color characteristics of the murals, accurately identifying user signals, and noticing 3D modeling of images via VR technology. This capability provides solid technical and data support for the platform’s interaction module. The interaction design, platform functionality, and layout can support the majority of users in terms of cognition, perception, and interaction, pique their interest, and enhance their experience, according to evaluation of trial user information. The interaction ends abruptly, according to a small percentage of users, and they had a bad experience overall.

Navigating the stacks virtually: Integrating virtual reality into writing resource instruction

Virtual reality (VR) presents a significant opportunity to expand remote access to educational materials and writing skills development for students not able or unwilling to participate in person. However, to ensure that VR-based learning is inclusive, research designs must incorporate user experience feedback. This study examines community college students’ feedback on a virtual library tour (VRT) for an Introduction to Writing course. Because building library skills is a key objective of this course, decreasing barriers to student library access is critical. Findings from the study indicate (1) most participants had a positive response and experienced a heightened sense of control (over 70%), though nearly half (48.1%) felt that the virtual experience did not fully replicate the real-life experience, (2) participants valued the structured guidance of the tour but recommended more flexibility and user agency within the VR environment, and (3) noted technical problems related to motion sickness, sound levels, and visual clarity. The study presents specific suggestions for enhancements and underscores the importance of utilizing design research to improve user experiences with VR. Directions for future research are also discussed.

Unearthing Subtle Cognitive Variations: A Digital Screening Tool for Detecting and Monitoring Mild Cognitive Impairment

Early diagnosis of mild cognitive impairment (MCI) is pivotal in mitigating the risk of cognitive impairment and the onset of dementia. However, prevailing clinical cognitive screening tests and biomarker assessment approaches often suffer from drawbacks such as high cost, invasiveness, time consumption, or subjectivity. In China, existing digital cognitive assessment tools face multiple challenges due to their distinctive cultural, language, and healthcare landscape. Therefore, we embarked on a study to develop a digital cognitive assessment tool, evaluate its efficacy in distinguishing between healthy individuals and MCI patients, and examine its acceptability among Chinese older adults. Through a series of symposiums, programming, and interviews with stakeholders, we iteratively designed the "BrainNursing" mobile application. The system consists of eleven single tasks and three dual tasks, each taking only 1–3 minutes. Subsequently, we conducted statistical comparisons of movement kinetics and physiological signals recorded during cognitive testing in 181 older adults to investigate which parameters could serve as effective digital biomarkers for MCI screening. Leveraging machine learning classifiers and a majority voting principle, we evaluated the classification performance of the BrainNursing system in detecting MCI, yielding an accuracy rate of 90.3%. Furthermore, our analysis of movement kinetics revealed that time, score, and sequence features are crucial in cognitive assessment. Contrasting with their healthy counterparts, MCI patients exhibited decreased heart rate variability, increased sympathetic nervous system activity, and weakened autonomic nervous system regulation in response to stimuli during cognitive testing. Finally, user experience feedback indicated that participants universally perceived BrainNursing as a convenient and user-friendly cognitive screening tool and provided valuable insights for further improvement.

Pengalaman Komunikasi Pria Pegiat Gym Pengguna Media Sosial Instagram

This research aims to determine the motives, meanings and communication experiences of male gym activists regarding posts related to gum. This research uses a qualitative research method with a phenomenological approach. Data was obtained through an in-depth interview process as well as field and online observations. The theory used is Alfred Schutz's phenomenological theory and Participatory Media Culture theory. The outcomes of the research indicate that the "cause" motive stems from feelings of insecurity or lack of confidence regarding one's physique, while the "goal" motive is characterized by a desire to garner attention, praise, and feedback from one's followers, as well as to capture a moment in time. Regarding gym-related posts, the participants viewed them as a means of conveying messages, expressing themselves, eliciting feedback, and serving as a source of motivation. Additionally, the participants' experiences of positive feedback and likes from their followers contributed to their posts serving as a motivational tool for their followers, while negative experiences took the form of vulgar comments and impolite direct messages from unknown individuals. This study employs phenomenological and communication experience approaches and focuses on men who work out at the gym.

An Association Rule Mining-Based Method for Revealing the Impact of Operational Sequence on Nuclear Power Plants Operating

The operations of the operators are important for nuclear safety, but conventional operating experience feedback and common data-driven methods make it difficult to explicitly find valuable information hidden in these operational sequences that can help the operator to provide advice at the operational level. During the nuclear power plant (NPP) operation, a large amount of historical operating data is accumulated, which records the operational sequences of the operators and the state parameters of equipment. Therefore, this paper proposes the use of association rule techniques to mine the NPP operating data to discover the operational characteristics of operators and reveal their possible impact on the NPP operation. This work helps to improve the operational performance of operators and prevent human-factor events. To this end, the concept of state switching values for describing the operating states of NPPs is proposed to enable the proposed method to be adapted to different practical application scenarios. A sequence segmentation method is proposed to be able to transform historical NPP operating data into a sequence data set for association rule mining. Furthermore, an ensemble algorithm based on sequence pattern mining and sequence rule mining and its postprocessing method are designed. The empirical study was carried out using 20 batches of historical operating data of the cold start-up. A total of 164 original association rules are generated using the proposed method and were analyzed by experts. The recommendations were made for 4 different cases that would improve the operational performance of the operators.

The user experience of distal arm-level vibrotactile feedback for interactions with virtual versus physical displays

Haptic feedback, a natural component of our everyday interactions in the physical world, requires careful design in virtual environments. However, feedback location can vary from the fingertip to the finger, hand, and arm due to heterogeneous input/output technology used for virtual environments, from joysticks to controllers, gloves, armbands, and vests. In this work, we report on the user experience of touch interaction with virtual displays when vibrotactile feedback is delivered on the finger, wrist, and forearm. In a first controlled experiment with fourteen participants and virtual displays rendered through a head-mounted device, we report a user experience characterized by high perceived enjoyment, confidence, efficiency, and integration as well as low perceived distraction, difficulty, and confusion. Moreover, we highlight participants’ preferences for vibrotactile feedback on the finger compared to other locations on the arm or through the VR controller, respectively. In a follow-up experiment with fourteen new participants and physical touchscreens, we report a similar preference for the finger, but also specific nuances of the self-reported experience, not observed in the first experiment with virtual displays. Overall, our results depict an enhanced user experience when distal vibrotactile feedback is available over no vibrations at all during interactions with virtual and physical displays, for which we propose future work opportunities for augmented interactions in virtual worlds.

Contribution of peer-feedback to the development of teamwork skills

Peer-feedback is a widely-used strategy at the university level for its positive impact on student learning and its multifaceted advantages encompassing social, cognitive, and metacognitive development. However, few studies have assessed its contribution to the development of teamwork skills. This study analyzes students’ perception of how peer-feedback contributes to the development of teamwork skills by comparing the results of two class groups that have taken the same subject, though with different feedback experience designs (face-to-face and mixed feedback vs. non-face-to-face and written feedback, with or without consensus among group members). At the end of the study, 82 participants completed a questionnaire to assess their perception of the peer-feedback experience and its impact on learning and the development of teamwork skills. The findings reveal that students perceive that giving and receiving feedback in face-to-face mixed modality contributes more to developing teamwork skills; however, the presence or absence of consensus among group members to give or receive feedback does not appear to exert a clear impact on the development of these skills. Additionally, the findings suggest that students perceive a greater development of teamwork skills by giving feedback rather than receiving it. These results highlight the importance for teachers to consider such aspects when designing peer-feedback experiences, aiming to maximize the impact on the development of teamwork skills.

ANALYSIS OF TEACHERS’ WRITTEN FEEDBACK ON WRITING SKILLS OF THIRD-YEAR ENGLISH-MAJORED STUDENTS AT A VIETNAMESE UNIVERSITY

In the realm of higher education, the acquisition of proficient writing skills is deemed a cornerstone of academic success, particularly for students majoring in English. However, developing writing skills is a complex and challenging process that requires effective instruction and feedback. Central to this journey is the role of teachers, who, through their written feedback, become instrumental guides in shaping and refining students’ writing abilities. This study, therefore, aims to investigate the perceptions, preferences, and attitudes of 56 third-year English-majored students at a university in Vietnam regarding teachers' written feedback on essays. The results show that students are engaged in essay writing and receive regular or frequent feedback. However, they have mixed emotions about feedback, ranging from eagerness to improve to feeling lost. They also have diverse preferences for feedback types, such as error correction, explanation, suggestion, etc. Most students agree that feedback helps their writing skills and motivates them to revise, but some also face challenges such as discouragement and uselessness. The study recommends a balanced and constructive feedback approach that considers students’ varied needs and addresses their challenges, which can enhance the feedback experience for students.

Ecosystem Services Value Realization and Ecological Industry Design in Scenic Areas of Karst in South China

Ecosystem services (ESs) value realization and ecological industry (eco-industry) are essential components of regional development. Due to the vulnerability and non-renewability of natural landscape resources in Karst areas, once unreasonable resource development takes place, it is easy to pose threats and causes damage to its ecosystem. This article selects the grain data correction equivalent factor coefficients in Guizhou Province, China, and establishes accounting indicators for Karst scenic areas. It is found that the total economic value of ESs is as follows: Shanmuhe Scenic Area (CNY 5096.3 thousand) > DaXiaoQiKong Scenic Area (CNY 2778.6 thousand) > Huangguoshu Scenic Area (CNY 2130.7 thousand). Among them, the value of regulating services plays a dominant role in the composition of ESs, and the value of forests accounts for the largest proportion. Through web crawlers, tourism data can be acquired, and the Product–Experience–Feedback–Improvement (PEFI) model can be applied to reveal that tourists have a predominantly positive perception of Karst scenic areas. This indicates that karst landscape resources are deeply loved by domestic and foreign tourists, especially mountain, water and forest landscapes. Based on the results of the ES value accounting of the scenic area and the external perception data of tourists towards the scenic area, the eco-industry spatial layout development plan is formulated. According to local conditions, the development, construction, and protection of the scenic area are carried out, jointly promoting the realization of the ecological product value (EPV) of the Karst scenic area, to determine the optimal development direction of the eco-industry, and to promote the coordinated development of ecological resources and assets.

In-hospital end-of-life care: an appreciative analysis of bereaved family feedback.

Experience feedback data is increasingly recognised as being helpful in improving healthcare services, and in meeting patient and family needs. This end-of-life care project, based on the principles of appreciative inquiry, sought to learn from the experiences of bereaved people whose relative had died in an acute hospital setting. Informal feedback, offered during a routine telephone call, was thematically analysed and interpreted in an appreciative manner. Confirmatory representations of caring practices and behaviours were identified, categorised and disseminated in a way that enabled staff to come to know and understand end-of-life care at its best, rather than as a set of problematised events. The findings served as a benchmark for individuals and teams to assess and progress their practice reflectively. The authors conclude that staff receptiveness to informal bereaved family feedback may be enhanced by focusing on the positive qualities of end-of-life care within existing practices.

Usefulness of working with a person-centred intervention in a group: Perspectives from facilitators and persons with mental illness.

When implementing new interventions into clinical practice, it is of great importance to investigate the implementation process to better understand factors promoting and impeding the implementation to stimulate engagement and sustainability of the intervention. It is essential to consider perspectives both from the health professionals delivering the intervention and those receiving the intervention to be open to their suggestions for enhancing the dissemination and implementation of the intervention. The aim of the study was to evaluate adoption, acceptabilityand appropriateness of a person-centred group intervention (PCGI) from the perspectives of facilitators and participants with mental illness in mental health outpatient services right after delivery. A qualitative interview study design was used. Interview data from three individual interviews, one group interview with facilitatorsand 16 individual interviews with participants were analyzed through content analysis. As described in the following three categories, the facilitators and participants found the PCGI overall useful and meaningful to deliver and receive: (1) application of a PCGI in clinical practice, (2) balancing the facilitator roleand (3) establishing and maintaining a safe relationship. Facilitators and participants found the form and structure of the PCGI useful and meaningful. Some participants dropped out as they did not feel comfortable in a group setting. The components in the sessions, questions on cards and reflectionsheets together with peer-to-peer interactions provided a safe environment. However, facilitation from facilitators requires appropriate skills and qualifications, which must be provided by the hospital together with supervision and the possibility for peer feedback and exchange of experiences.

A Voice-Activated Device Exercise and Social Engagement Program for Older Adult-Care Partner Dyads: Pilot Clinical Trial and Focus Group Study Evaluating the Feasibility, Use, and Estimated Functional Impact of EngAGE.

Maintaining exercise is essential for healthy aging but difficult to sustain. EngAGE is a socially motivated exercise program delivered over a voice-activated device that targets older adult-care partner dyads. This 10-week pilot study aimed to assess EngAGE feasibility and use, obtain user experience feedback, and estimate potential impact on function. In total, 10 older adults aged ≥65 years were recruited from an independent living residence together with their self-identified care partners. EngAGE delivered National Institute on Aging Go4Life exercises to older adults daily, while care partners received progress reports and prompts to send encouraging messages that were read aloud by the device to the older adult. Older adults' use was tracked, and physical function was assessed at baseline and follow-up. Follow-up focus group data provided qualitative feedback. On average, participants completed 393.7 individual exercises over the 10-week intervention period or 39.4 exercises/wk (range 48-492, median 431, IQR 384-481, SD 112.4) without injury and used EngAGE on an average of 41 of 70 days or 4.1 d/wk (range 7-66, median 51, IQR 23-56, and SD 21.2 days). Mean grip strength increased nonsignificantly by 1.3 kg (preintervention mean 26.3 kg, SD 11.0; postintervention mean 27.6 kg, SD 11.6; P=.34), and 4 of 10 participants improved by a minimal clinically important difference (MCID) of 2.5 kg. Further, the time for 5-repeated chair stands significantly reduced by 2.3 seconds (preintervention mean 12, SD 3.6 s; postintervention mean 9.7, SD 2.7 s; P=.02), and 3 of 9 participants improved by an MCID of -2.3 seconds. Furthermore, 3-meter usual walk performance was brisk at baseline (mean 2.1, SD 0.4 s) and decreased by 0.1 seconds (postintervention 2, SD 0.4 s; P=.13), although 5 of 9 participants improved by a MCID of 0.05 m/s. Qualitative results showed perceived benefits, favored program features, and areas for improvement. We present a pilot study of a new voice-activated device application customized to older adult users that may serve as a guide to other technology development for older adults. Our pilot study served to further refine the application and to inform a larger trial testing EngAGE's impact on functional outcomes, a necessary step for developing evidence-based technology tools.

What’s in a word? – unpacking European students’ conceptualisations and experiences of feedback

ABSTRACT European students bring with them a variety of feedback experiences and literacies. Yet this variety tends to be underexplored. This study unpacks European students’ past experiences of feedback and the expectations they bring with them to the new learning context at a STEMM UK institution. Through examining the meaning behind the word feedback and the concept of feedback in students’ first languages, the study gives insight into the status of feedback in their previous contexts, how it translated onto practice and how it shaped students’ feedback expectations and practices in the new context.

Investigating the Influencing Factors of the Perception Experience of Historical Commercial Streets: A Case Study of Guangzhou’s Beijing Road Pedestrian Street

Given the complex interplay between economic and cultural–historical factors, this paper explores scene perception and its mechanism in individual and collective cognition of historical commercial streets. Based on a perception model constructed from scene theory, the study utilizes user scene experience feedback from Beijing Road, a commercial pedestrian street in Guangzhou. It conducts a systematic assessment using hierarchical analysis (AHP) across three dimensions: authenticity, theatricality, and legitimacy. The findings reveal the following: (1) according to visitors, traditional cuisine, cultural and creative arts, and Lingnan’s intangible cultural heritage received low ratings; (2) historical relics and traditional cuisine are dominant factors, highlighting public attention to cultural heritage, but the role of historical–cultural characteristics and festival activities is relatively marginalized; (3) cultural–historical relics and traditional cuisine are the leading factors that contribute to an authentic experience, while historical context and festival activities constitute secondary factors; (4) cultural landscapes and arts are central to theatrical experiences, with modern visual elements playing a lesser role; (5) diversified commercial formats and public services are the core factors influencing legitimacy experience, reflecting the role of market diversity and policy orientation in building consumer trust. The design of historical and cultural streets should prioritize the preferences of those experiencing them to promote cultural identity and historical continuity. Additionally, the synergy between commercial diversity and policy orientation should be strategically emphasized to form a business ecosystem supporting sustainable development. Future commercial street renewals should focus on the key role of visual narrative in shaping brand culture. This paper offers insights into the dynamic process of constructing scene experience from perspectives of spatial materialization and emotional empowerment to cultural identity, providing references for strategies in historical place renewal.

Data acquired on some old reinforced concrete structures to validate the threshold levels of the French performance‐based method for the durability of concrete structures

AbstractThe objective of this paper is to present the methodology used to validate the threshold levels of durability indicators from data acquired from existing reinforced concrete structures that may present corrosion problems resulting from carbonation or chloride ingress. This study was conducted in the framework of the French National Project PERFDUB in close collaboration with the MODEVIE ANR project. Durability tests form the basis of a performance‐based approach for the durability of concrete structures, and in order to set the threshold level for each of these durability indicators, it is important to take into account the experience feedback that can be obtained from the actual behavior of existing structures. This paper presents the investigations carried out on eight reinforced concrete structures, all of them having an age well in excess of 50 years, and the main data gathered on some relevant durability and lifetime indicators. Based on all these data, predictive models of carbonation and chloride penetration are applied in order to validate the threshold levels to be adopted for the durability indicators, and several other conclusions are drawn.

"Well I Failed, but I Have No Idea Why"…: Experiences of Feedback After High-Stakes Summative Specialist Medical Examination in Ophthalmology.

Medical specialist trainees report dissatisfaction with both the usefulness and timing of feedback provided following summative examinations. This study aimed to explore ophthalmology trainee and supervisor experiences of feedback following final summative examination (the Royal Australian and New Zealand College of Ophthalmologists Advanced Clinical Examination (RACE)). Semi-structured interviews were undertaken with ophthalmology trainees who had recently sat RACE (2017-2021) (n = 19) and supervising ophthalmologists who support trainees to prepare for RACE (n = 10). Interview data were thematically analyzed. Two themes were identified. Inadequate feedback related to trainee experiences receiving feedback relating to examination performance that was insufficient and unhelpful in identifying gaps in learning, explaining the reasons for failure and supporting preparation for resitting. Inability to contextualize feedback encompassed trainee and supervisor concerns regarding the inability to review examination manuscripts after sitting the examination, the absence of marking criteria, rubrics and model answers to understand the passing standard and the lack of opportunity to discuss performance with examiners. Detailed, individualized task-level and process-level feedback on examination performance is needed for all trainees. Opportunities to view examination manuscripts, marking criteria and model answers, as well as speak with examiners, would improve transparency of the assessment process, enhance feedback and improve trainee success.

Empowering the Participant Voice (EPV): Design and implementation of collaborative infrastructure to collect research participant experience feedback at scale.

Empowering the Participant Voice (EPV) is an NCATS-funded six-CTSA collaboration to develop, demonstrate, and disseminate a low-cost infrastructure for collecting timely feedback from research participants, fostering trust, and providing data for improving clinical translational research. EPV leverages the validated Research Participant Perception Survey (RPPS) and the popular REDCap electronic data-capture platform. This report describes the development of infrastructure designed to overcome identified institutional barriers to routinely collecting participant feedback using RPPS and demonstration use cases. Sites engaged local stakeholders iteratively, incorporating feedback about anticipated value and potential concerns into project design. The team defined common standards and operations, developed software, and produced a detailed planning and implementation Guide. By May 2023, 2,575 participants diverse in age, race, ethnicity, and sex had responded to approximately 13,850 survey invitations (18.6%); 29% of responses included free-text comments. EPV infrastructure enabled sites to routinely access local and multi-site research participant experience data on an interactive analytics dashboard. The EPV learning collaborative continues to test initiatives to improve survey reach and optimize infrastructure and process. Broad uptake of EPV will expand the evidence base, enable hypothesis generation, and drive research-on-research locally and nationally to enhance the clinical research enterprise.
