To investigate the effects of block design on these risks, 25 participants in a repeated-measures laboratory study handled a pot under two block conditions: away-from-table (conventional setting) and above-table (intervention). Low back and shoulder muscle activities, angles, moments, perceived exertion, and postural stability were measured. The results showed reduced L5/S1 and shoulder moments and angles; decreased muscle activities in the low back, shoulders, and upper extremities; and lower perceived exertion ratings and postural sway measures with the intervention.

Thirty participants interacted with an SAV mock-up and participated in subsequent focus group discussions regarding their interaction experiences and general perceptions of SAV. Quantitative video-based time-motion analysis and qualitative thematic analysis of the focus group discussion highlighted concerns related to a) ingress and egress accessibility; b) seat and cabin comfort; c) appropriate social interactions with co-riders; and d) SAV operational functionality. Staggered seating arrangements and multi-functional use of available space were preferred features. The analysis also identified potential improvements, such as the inclusion of additional handholds and efficient HVAC systems, and underscored the need for central monitoring for emergency interventions during SAV operations. Ultimately, findings from this research can provide valuable insights for researchers and engineers to design equitable transportation solutions tailored to a broad range of traveler abilities and needs.</div></div>","PeriodicalId":55502,"journal":{"name":"Applied Ergonomics","volume":"123 ","pages":"Article 104408"},"PeriodicalIF":3.1,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142683722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An operator approaching a collaborative robot (cobot) may have feelings of distrust, and experience discomfort and stress, especially during the early stages of training. Human factors cannot be neglected: for efficient implementation, the complex psycho-physiological state and responses of the operator must be taken into consideration. In this study, volunteers were asked to carry out a set of cobot programming tasks, while several physiological signals, such as electroencephalogram (EEG), electrocardiogram (ECG), Galvanic skin response (GSR), and facial expressions were recorded. In addition, a subjective questionnaire (NASA-TLX) was administered at the end, to assess if the derived physiological parameters are related to the subjective perception of stress.
