Proceedings International Conference on Software Engineering, 2024
Background: Many programming environments include automated feedback in the form of hints to help novices learn autonomously. Some experimental studies investigated the impact of automated hints in the immediate performance and learning retention in that context. Automated feedback is also becoming a popular research topic in the context of formal specification languages, but so far no experimental studies have been conducted to assess its impact while learning such languages. Objective: We aim to investigate the impact of different types of automated hints while learning a formal specification language, not only in terms of immediate performance and learning retention, but also in the emotional response of the students. Method: We conducted a simple one-factor randomised experiment in 2 sessions involving 85 BSc students majoring in CSE. In the 1st session students were divided in 1 control group and 3 experimental groups, each receiving a different type of hint while learning to specify simple requirements with the Alloy formal specification language. To assess the impact of hints on learning retention, in the 2nd session, 1 week later, students had no hints while formalising requirements. Before and after each session the students answered a standard self-reporting emotional survey to assess their emotional response to the experiment. Results: Of the 3 types of hints considered, only those pointing to the precise location of an error had a positive impact on the immediate performance and none had significant impact in learning retention. Hint availability also causes a significant impact on the emotional response, but no significant emotional impact exists once hints are no longer available (i.e. no deprivation effects were detected). Conclusion: Although none of the evaluated hints had an impact on learning retention, learning a formal specification language with an environment that provides hints with precise error locations seems to contribute to a better overall experience without apparent drawbacks. Further studies are needed to investigate if other kind of feedback, namely hints combined with some sort of self-explanation prompts, can have a positive impact in learning retention. - UX and Industry 5.0: A Study in Repairing Equipment Using Augmented Reality

Loading pallets in truck bays presents significant human factors challenges, including physical ergonomics, workplace safety, task efficiency, and operator well-being. Forklift operation, in particular, demands both physical and cognitive effort and carries a risk of injury. Work injuries have significant social and economic impacts, both for the injured individuals and for the company. Therefore, analyzing ways to reduce these risks, streamline processes, and enhance efficiency is crucial for both human and organizational well-being. This study focused on analyzing the current operational flow of pallet loading in an industrial facility where this process is integral to production. Using a user journey map, which combined storytelling and material visualization, issues were identified from a human factors perspective issues from the perspective of human factors. The study followed the early stages of the Design Thinking Methodology, particularly in need identification and problem definition. In the initial phase, a multidisciplinary human factors team visited the workstation, employing observation, semi-structured interviews, and on-site recordings. This data was validated through consultations with operators. In the second phase, the user journey was outlined, highlighting six dimensions: user actions, interfaces, goals, experiences, emotions, pain points, and opportunities. After that the user journey map was validated with an industrial team.Through an empathic analysis based on user-centered design, the journey map revealed critical issues such as visibility frustrations and maneuverability challenges. By deeply understanding the operators' experiences, the study provided practical insights and recommendations for improving safety, efficiency, and overall operator well-being. - What Times Should Be Used for fNIRS and EEG Protocol?

: The present study aimed to assess how professionals from the aviation industry perceived the usability of an application aimed at developing prototypes of airplane cockpits, in virtual reality, from a human-centred design perspective. 12 participants from the aeronautical industry took part in the study. An evaluation using the SUS (System Usability Scale) resulted in a final score of 81.3, while the results from the SAM (Self-Assessment Manikin) indicated a neutral-positive trend towards the application. From participant’s observations and comments, the application’s potential to improve airline security, pilot comfort, and cockpit design efforts, was recognized and appreciated. Despite the positive interactions, some aspects of the application were found to need further improvement, to better align with the expectations and needs of the professionals towards which the application is being geared to. - Digital Tools for Aircraft Maintenance: Prototyping Location-Aware AOI for Engine Assessment and Cable Routing Solutions

Aircraft maintenance plays a vital role in ensuring not only public safety but also aircraft availability and financial viability. However, carrying out such activities traditionally leaves gaps for processual optimizations with the potential of increasing the overall performance and satisfaction of operators and engineers who deal with these responsibilities. Currently, available technologies may enable the increment of quality in aircraft maintenance processes, namely, the ones based on xReality and deep learning. Therefore, this paper proposes two use-cases based on real aircraft maintenance context requirements: one employing augmented reality for cable routing, enabling cataloguing and also previewing the position and paths of cable systems inside the fuselage kit; and another making use of deep learning and virtual environments to aid in the activities related with engine baroscopic inspections, with position awareness capabilities. Results regarding a few functional and usability tests are also presented and discussed. In spite of their still incipient maturity, both these tools showed potential for being involved in the pipelines of aircraft maintenance in the future. - Microbial Resource Research Infrastructure for the 21st Century: Usability Analysis of the Collaborative Working Environment

Ease-of-use is of paramount importance to ensure the acceptability of a virtual platform. With that in mind, we sought to evaluate the usability of Microbial Resource Research Infrastructure (MIRRI)’s Collaborative Working Environment (CWE). Usability tests intend to determine whether an interface facilitates a user’s ability to complete tasks in the platform analyzed. For the MIRRI’s CWE user tests, 29 participants, aged between 25 and 65 years old, from 10 countries (Brazil, Chile, Colombia, France, Italy, Latvia, Netherlands, Peru, Portugal, Spain), with different professional backgrounds (i.e. Research/ Education, industry, Officers, among others) were invited to carry out activities within 3 modules of the platform, namely: (1) Microbial Resources Catalog (MRC), (2) Services and Workflows Catalog (SWC) and the (3) Transnational Access information and application submission (TNA). At the end of the experience, participants were asked to fill out the System Usability Scale (SUS) - a standardized questionnaire widely used to measure usability. Based on the SUS analysis, participants had a good perception of the usability of the MIRRI platform. MIRRI's CWE platform innovates in the unification of data and information from the microbiological universe. The usability analysis validates the user experience, thus ensuring that acceptance by the users is not hindered by poor ease-of-use. - fNIRS An Emerging Technology for Design: Advantages and Disadvantages
