This study aims to identify conditions that promote work sustainability after technological transition processess in an industrial context, and understand the possibilities of operators' involvement in these. Two use-cases in a manufacturing company were part of the study with the project development team, HR, team leaders and the workers who will interact with the new technologies. Following a work activity-oriented approach, the results demonstrated that there is still progress to be made to move towards a human-centered approach (e.g., consideration for workers and their work activity; organizational support to skills development). However, conditions that favor a renewed work activity within the technological transitions aligned with the I5.0 paradigm were also found and taken into account into an evidence-based framework of guidelines for sustainable work conditions. This framework considers an organizational, collective, and individual level of guidelines aimed to support companies’ stakeholders in the design and implementation of human-centered technological transitions. This study contributes to fostering the I5.0 transition, seeking sustainable conditions for workers and their work possibilities.

Rope skipping is now a popular and effective weight loss method enjoyed by many individuals. However, due to the limited support from muscles and bones in the female breasts, breast tissue moves relative to the chest wall during physical activities, leading to discomfort, especially in women with larger breasts. This study aims to explore the movement range of larger breasts in relation to the chest with a focus on analysing the jumping-induced boundary position of the breast and its biomechanical characteristics during rope skipping exercises. By employing the 4D dynamic body scanning technology, the study recorded the breast movement of women with larger breasts during cordless rope skipping exercises under the braless condition, to identify the moment and location of the maximum movement boundary of the breast in the vertical direction. The results indicated that within 0.2 ± 0.05s of the rope skipping cycle, the upward movement of the breasts would reach their maximum, followed by downward sliding. Furthermore, it was also found that the breasts not only moved vertically during the rope skipping cycle, but also slide outward along with the curvature of the thorax. By analysing the motion range of the upper boundary across all participants, it was found that these boundary points typically located 4–7 cm above the line connecting the anterior axillary points. This study provides a new method and reference for defining the biomechanical boundaries of larger breasts, offering a valuable foundation for sports bra design, especially the design for upper breast region.

Peripheral vision plays a crucial role in assisting drivers with searching for traffic information. Previous studies have explored the association between drivers' peripheral vision and their hazard perception ability, but the impact of peripheral vision on driving behavior remains unclear. Thirty-five participants were recruited to conduct a peripheral vision test and a driving simulation experiment. Then, field of view range, number of correct and incorrect responses, target tracking deviation, and perception time were used to assess the peripheral vision perception ability of individuals. The time to first fixation on hazards, brake reaction time, Standard Deviation of Steering Wheel angle (SDSW), and average speed were selected as dependent variables. Then, the influence of the Peripheral Perception-Response Score (PP-RS) and lateral conflict type on driving performance was assessed. The study finds a significant relationship between the driver's PP-RS and lateral stability, with higher PP-RS scores correlating with smaller standard deviation of steering wheel angle. It also reveals that drivers exhibit a longer first fixation time (p < 0.001) and a delayed reaction time (p = 0.001) when encountering a bicycle crossing compared to a vehicle crossing the roadway. The delay in first fixation time and reaction time are about 0.65 s and 0.67 s, respectively. A similar pattern is observed when pedestrians cross a roadway without a crosswalk. Drivers with higher PP-RS scores can perceive risky conflicts earlier when encountering a crossing vehicle, although they do not always slow down earlier. These findings provide valuable theoretical for improving driver training policies.

Large-screen displays have gained increasing popularity and can be operated through both freehand and device-assisted approaches for distant interaction. However, how these interaction approaches work in different large-screen display usage scenarios has seldom been examined. This study was conducted to provide an ergonomic comparison of freehand and device-assisted interactions with large-screen displays under varied postures and user-to-display distances. A within-subjects counterbalanced study design was used, where participants were required to interact with a large-screen display by freehand and two device-assisted approaches under sitting and standing postures and at four user-to-display distances. Two target sizes were also examined. The results showed that, compared with device-assisted approaches, freehand interaction presented poorer ergonomic performance, in terms of lower efficiency, accuracy and perceived usability, and higher workload. Interaction approach significantly interacted with user-to-display distance and posture on task performance and usability dimensions. Freehand interaction was particularly less efficient in standing posture and less effective at closer distances. Posture and user-to-display distance also significantly interacted with each other on task performance. Target size exerted varied effects on task performance by task types.
Relevance to industry
Our results indicate that freehand interaction tends to exhibit poorer ergonomic performance compared with device-assisted approaches, particularly under suboptimal posture-distance conditions. The findings offer valuable insights for improving the design, configuration and adoption of interaction techniques for large-screen displays, especially in distant interaction scenarios.

Generative AI is increasingly used in team ideation, but how its design features affect creative performance is unclear. Research on human teams suggests that such effects are mediated by team emergent states (TESs, the team's cognitive and emotional dynamics and feelings). Yet, whether TESs play a similar role in team-AI co-ideation remains unknown. This study explored the effects of AI content strategies (breadth-first vs. depth-first) and participation styles (active vs. passive) on TESs and performance during team-AI collaborative ideation by a mixed-design experiment with 52 students and in-depth interviews with seven professionals from industry. In the experiment, two participants and AI as a team brainstormed and developed design solutions. We found depth-first strategies fostered stronger convergence among ideas and members and further enhanced solution completeness, whereas breadth-first AI increased divergent performance and solution practicability. AI design influenced both cognitive and affective TESs, which predicted objective and subjective performance differentially. This study reveals how the design of generative AI affects human-AI collaborative ideation through the perspective of TES and suggests designing generative AI to adjust to TESs and the creative process.

Various vehicles expose occupants to whole-body vibration (WBV), leading to subjective discomfort in seated individuals. This study investigates the impact of different seat-human contact configurations on subjective discomfort under WBV conditions. Combining the relative magnitude estimation (RME) and absolute magnitude estimation (AME) methods, a static sitting discomfort experiment was conducted before vibration testing to establish subjects' perception of discomfort levels. Under simulated Class C road excitation, five seat-human contact conditions were tested, with data collected on beats per minute (BPM), arterial oxygen saturation (SaO2), subjective discomfort ratings, and discomfort locations. Results show a significant positive correlation (Spearman's ρ = 0.72, p = 0.002) between the frequency of BPM ‘relative peak’ and subjective discomfort occurrences. Backrest, armrest, and gripping a column reduced the frequency of BPM ‘relative peak’ by 35.3 %, 20.3 %, and 39.8 %, respectively. Headrests and armrests exhibited negative masking effects on discomfort perception, while backrests and gripping a column demonstrated positive masking effects. The optimization of seat design, especially the features of the backrest and column grip, can substantially alleviate the discomfort caused by vibration. This study provides theoretical insights for improving seat-human interaction and enhancing ride comfort.

Aircraft cockpits reduce safety risks by providing intelligent human-computer interactions that enhance the naturalness of the pilot's interaction with on-board systems. The goal of this exploratory study was to look into the effect of various interaction modalities on pilot performance, including task performance, workload, and user experience. In an unifactorial within-subjects multilevel trial, 25 male participants performed a take-off task in an aircraft multimodal interaction cockpit platform. The investigation evaluates the differences in pilot performance between gesture interaction and gesture in conjunction with other interaction modalities, using a traditional manipulation interaction modality as a control. Experimental data was analyzed by statistical tests on significance and effect sizes. The results suggest that interaction modality affects task completion time, physical demand, and objective physiological characteristics. Gesture interaction required less mental demand and time than traditional control interaction but had the highest physical demand. Gesture and voice interaction was more advantageous than gesture interaction and traditional control interaction in terms of reducing the pilot's workload and improving the operational experience. The above conclusions indicated that gesture and voice interaction was ideal for the next-generation civil aircraft cockpit for flight tasks.

Artificial intelligence (AI), as an advanced technological innovation, possesses considerable promise for improving energy efficiency and reducing emissions in industrial environments. Although AI plays a crucial role in industrial decarbonization, research reveals that many AI-dependent carbon reduction prospects remain untapped. This study examines the innovative correlation between the presentation styles of industrial AI recommendations and the trust that carbon management technicians have in AI from an ergonomic standpoint. This study combines the Stimulus-Organism-Response theory with the Elaboration Likelihood Model. The findings from three experiments reveal that precise and informative styles of AI recommendations enhance trust among technicians. Furthermore, we present mediating evidence with advanced eye-tracking devices, illustrating that cognitive effort strengthens the positive effect of precise abatement recommendations on trust toward AI (Study 2). Further research indicates that the positive effect of precise or informative AI-generated abatement recommendations on trust is amplified when technicians experience more positive emotions (Study 3). Overall, this study identifies distinct mechanisms through which the presentation styles of industrial AI recommendations can affect technicians' trust. These findings hold practical significance for developers of industrial AI systems and carbon management technicians who strategically utilize AI-generated information.

Objective
To compare visual versus haptic cueing modalities in modulating gait variability temporal structure using white noise, pink noise, and invariant interval patterns.
Background
Healthy human movement exhibits "pink noise" variability, representing optimal balance between stability and adaptability. Aging and pathology disrupt this pattern. While external cueing can help restore healthy patterns, visual and auditory approaches limit environmental awareness.
Method
Ten healthy young adults completed 12-min walking trials for each cueing condition across two counterbalanced sessions. Gait variability was quantified through Detrended Fluctuation Analysis (α) of inter-stride intervals. Synchronization accuracy between heel strikes and cues was measured as asynchrony. Usability was assessed using a modified System Usability Scale.
Results
Bayesian multilevel modeling showed noise condition significantly influenced α values, with white noise and invariant conditions reducing α values compared to control and pink noise conditions. Asynchrony values were not influenced by cueing type, modality, or session. Haptic cueing was strongly preferred over visual for frequent use (P = 0.985), reduced awkwardness (P = 0.996), and increased confidence (P = 0.996).
Conclusion
Both modalities effectively modulated gait variability, with no differences in synchronization performance. However, haptic cueing received significantly higher usability ratings in key areas.
Application
Haptic cueing offers an effective alternative to visual cueing for gait rehabilitation, providing similar effectiveness while maintaining environmental awareness and better user experience, with potential applications through wearable technologies.

The Work-Oriented Training Path (WOTP) in Quebec, Canada, is a dual vocational training program that offers students with learning difficulties supervised traineeships. Teachers play a pivotal role in managing students' occupational health and safety (OHS), yet must do so under tight time constraints, limited institutional guidance and highly diverse student profiles. Building on an activity-centered ergonomics and capabilities framework, this multiple-case study explores how gender, disabilities, and work determinants shape OHS management within the WOTP, emphasizing their implications for social sustainability. Twenty-seven semi-structured interviews were conducted with 15 WOTP teachers; 497 narrated anecdotes, which are units of speech when teachers' talk about students, were thematically analyzed to capture everyday mechanisms that expand or restrict safe participation in traineeship. The findings highlight challenges stemming from power dynamics between teachers, parents, and employers, which influence the operational leeway available for teachers to implement OHS prevention. Their work organization, conditions and tools also expand or restrict their capability to have an equitable approach. Additionally, the analysis reveals disparities in traineeship placement opportunities and OHS prevention, particularly concerning students’ gender identity and disabilities. Key factors influencing traineeship placements and OHS practices included students' communication skills, perceived autonomy, and suitability of behavior compared to social norms. Students with disabilities are frequently assigned repetitive tasks, increasing exposure to hazards that remain under-recognized. These results underscore the critical need for inclusive OHS prevention, fostering a more socially sustainable approach within vocational training programs.
