Trust in automated vehicles (AVs) has traditionally been explored through a cognitive lens, but growing evidence highlights the significant role emotions play in shaping trust. This study moves beyond correlation to formally test the mechanisms through which emotions mediate the relationship between real-time AV performance and trust. We conducted an experimental study with 70 participants (42 male, 28 female) who viewed real-life AV recordings operating with or without errors, coupled with varying levels of risk information (high, low, or none). Participants reported their anticipated emotional responses using 19 discrete emotion items, while trust was assessed through dispositional, learned, and situational trust measures. Through factor analysis, 4 key emotional components were extracted, namely hostility, confidence, anxiety, and loneliness, that were influenced by risk perception and AV performance. Using mediation analysis, the extent to which four emotional factors explain the effect of AV performance on trust was quantified. The results show that real-time AV behavior is more influential on trust than pre-existing risk perceptions, indicating trust in AVs might be more experience-based than shaped by prior beliefs. The mediation analysis revealed major asymmetry in the power of emotional mediators: confidence emerged as the primary psychological pathway to trust, mediating 46.7% of the performance–trust effect. In contrast, negative emotions showed substantially weaker mediating effects. Hostility (11.3%) and anxiety (17.7%) were significant but substantially weaker negative mediators, while loneliness did not significantly mediate the relationship between AV performance and trust. Linear mixed modeling supported these patterns, confirming that unlike risk perception, AV performance and individual differences serve as the primary predictors of trust. These findings quantify trust’s emotional architecture, revealing that fostering positive emotional responses is more powerful than mitigating negative ones. AV development should therefore prioritize performance reliability and confidence building over safety communication or anxiety reduction.
传统上,对自动驾驶汽车(av)的信任一直是通过认知视角来探索的,但越来越多的证据表明,情感在塑造信任方面发挥着重要作用。本研究超越了相关性,正式测试了情绪调节实时AV性能与信任之间关系的机制。我们对70名参与者(42名男性,28名女性)进行了一项实验研究,他们观看了真实的AV录音,有或没有错误,同时有不同程度的风险信息(高、低或无)。参与者报告了他们预期的情绪反应,使用19个离散的情绪项目,而信任是通过性格、学习和情境信任来评估的。通过因子分析,提取敌意、自信、焦虑和孤独4个关键情绪成分,分别受风险感知和AV表现的影响。运用中介分析,量化了四种情绪因素对AV绩效对信任影响的解释程度。结果表明,实时自动驾驶汽车行为对信任的影响大于预先存在的风险感知,表明自动驾驶汽车的信任可能更多地基于经验,而不是由先前的信念塑造。中介分析揭示了情绪中介力量的不对称性:信心成为信任的主要心理途径,中介了46.7%的绩效信任效应。相反,负面情绪的中介作用明显较弱。敌意(11.3%)和焦虑(17.7%)是显著但明显较弱的负向中介,而孤独感在AV表现与信任之间的中介作用不显著。线性混合模型支持这些模式,证实与风险感知不同,AV表现和个体差异是信任的主要预测因子。这些发现量化了信任的情感结构,揭示了培养积极的情绪反应比减轻消极的情绪反应更有力。因此,自动驾驶汽车的开发应优先考虑性能可靠性和建立信心,而不是安全沟通或减少焦虑。

Advancements in artificial intelligence (AI) have ushered in the era of the fourth industrial revolution, transforming workplace dynamics with AI's enhanced decision-making capabilities. While AI has been shown to reduce worker mental workload, improve performance, and enhance physical safety, it also has the potential to negatively impact psychosocial factors, such as work meaningfulness, worker autonomy, and motivation, among others. These factors are crucial as they impact employee retention, well-being, and organizational performance. Yet, the impact of automating decision-making aspects of work on the psychosocial dimension of human-AI interaction remains largely unknown due to the lack of empirical evidence. To address this gap, our study conducted an experiment with 102 participants in a laboratory designed to replicate a manufacturing line. We manipulated the level of AI decision support—characterized by the AI's decision-making control—to observe its effects on worker psychosocial factors through a blend of perceptual, physiological, and observational measures. Our aim was to discern the differential impacts of fully versus partially automated AI decision support on workers' perceptions of job meaningfulness, autonomy, competence, motivation, engagement, and performance on an error-detection task. The results of this study suggest the presence of a critical boundary in automation for psychosocial factors, demonstrating that while some automation of decision selection can nurture work meaningfulness, worker autonomy, competence, self-determined motivation, and engagement, there is a pivotal point beyond which these benefits can decline. Thus, balancing AI assistance with human control is vital to protect psychosocial well‑being. Practically, industry and operations managers should keep employees involved in decision making by adopting partial, confirm‑or‑override AI systems that sustain motivation and engagement, boosting retention and productivity.
人工智能(AI)的发展引领了第四次工业革命时代,通过人工智能增强的决策能力改变了工作场所的动态。虽然人工智能已被证明可以减少工人的精神工作量,提高绩效,增强人身安全,但它也有可能对社会心理因素产生负面影响,如工作意义,工人自主权和动机等。这些因素至关重要,因为它们会影响员工的留任、幸福感和组织绩效。然而,由于缺乏经验证据,自动化决策方面的工作对人类与人工智能互动的社会心理维度的影响在很大程度上仍然未知。为了解决这一差距,我们的研究在一个旨在复制生产线的实验室中对102名参与者进行了一项实验。我们操纵人工智能决策支持的水平——以人工智能的决策控制为特征——通过感知、生理和观察措施的混合来观察其对工人心理社会因素的影响。我们的目的是辨别完全自动化和部分自动化的人工智能决策支持对工人对工作意义、自主性、能力、动机、参与度和错误检测任务表现的看法的不同影响。本研究的结果表明,在社会心理因素的自动化中存在一个关键的边界,表明虽然决策选择的一些自动化可以培养工作的意义、员工的自主性、能力、自主动机和参与度,但有一个关键点,超过了这个临界点,这些好处就会下降。因此,平衡人工智能援助与人类控制对于保护社会心理健康至关重要。实际上,行业和运营经理应该通过采用部分、确认或覆盖的人工智能系统来保持员工参与决策,从而保持积极性和参与度,提高员工留存率和生产力。

Nowadays, artificial intelligence (AI) and its applications (represented by virtual agents) are gaining increasing popularity in people's daily lives; and trust in them plays a crucial role in influencing the acceptance and usage of AI. Anthropomorphism is a fundamental element in studying human-machine trust. However, the findings regarding the impact on trust in AI are inconsistent, and the underlying mechanism remains unclear. To address these gaps, three studies were conducted to examine the influence of behavioral anthropomorphism (manipulated by emoticons use) on the trust in virtual agents, as well as the potential moderating and mediating mechanisms. The results revealed that behavioral anthropomorphism positively affected trust in AI. More importantly, this study identified the boundary conditions (the moderating effect of attitudes towards AI) and internal mechanisms (the mediating roles of warmth and competence). It is worth noting that excessive anthropomorphism (behavioral anthropomorphism and appearance anthropomorphism exist at the same time) may cause the uncanny valley effect, thereby damaging trust in AI. Additionally, it was found that the positive effect of anthropomorphism on AI trust is more prominent among individuals who hold negative attitudes towards AI. Overall, the study offered theoretical foundations and practical guidelines for effective AI-human interaction and trust-building strategies.
如今,人工智能(AI)及其应用(以虚拟代理为代表)在人们的日常生活中越来越普及;对他们的信任在影响人工智能的接受和使用方面起着至关重要的作用。拟人化是研究人机信任的基本要素。然而,关于人工智能对信任的影响的研究结果并不一致,其潜在机制尚不清楚。为了解决这些空白,本研究进行了三项研究,以检验行为拟人化(由表情符号的使用操纵)对虚拟代理信任的影响,以及潜在的调节和中介机制。结果显示,行为拟人化正向影响对人工智能的信任。更重要的是,本研究确定了边界条件(对人工智能态度的调节作用)和内部机制(热情和能力的中介作用)。值得注意的是,过度的拟人化(行为拟人化和外表拟人化同时存在)可能会造成恐怖谷效应,从而损害对AI的信任。此外,我们发现拟人化对人工智能信任的积极影响在对人工智能持消极态度的个体中更为突出。总体而言,该研究为有效的人工智能-人类互动和信任建立策略提供了理论基础和实践指导。

Navigating the challenges of remotely supporting blind riders in ridesharing 应对远程支持盲人搭车的挑战

Ridesharing services often rely on co-located drivers to assist blind users. This process involves users disclosing their disability to drivers, who might otherwise remain in their vehicles before pick up or stop in inaccessible locations. There are, however, emerging scenarios where users may instead prefer to leverage remote sighted support, e.g., in the case of discrimination, driver unwillingness to assist, or the absence of a driver in autonomous rides. While remote support offers a promising solution, prior studies have primarily focused on simple navigation tasks rather than real-time guidance for intricate vehicle identification, entry, and exit tasks in complex urban environments. To address this gap, we conducted a smartphone-based study with 10 users and three remote orientation and mobility guides. Grounded in the realistic context of busy urban conditions, our in-situ analysis of support strategies provides nuanced insights into in-the-wild usability not possible from interviews and lab experiments alone. We further identify frequent issues in discrimination and ride cancellations, further highlighting the growing importance of remote-sighted support in vehicle-interactive tasks. Our findings inform the design of accessible ride services by addressing wait times, failure cases (e.g., incorrect ride identification), and refined support guidelines that consider practical system limitations and user needs during origin-to-vehicle-to-destination travel.
拼车服务通常依靠同处一地的司机来帮助盲人用户。在这个过程中,用户需要向司机披露自己的残疾,否则司机可能会在接车或在无法到达的地方停车之前留在车内。然而,在一些新出现的情况下,用户可能更愿意利用远程视觉支持,例如,在歧视、司机不愿意协助或无人驾驶的情况下。虽然远程支持提供了一个很有前途的解决方案,但之前的研究主要集中在简单的导航任务上,而不是在复杂的城市环境中进行复杂的车辆识别、进出任务的实时指导。为了解决这一差距,我们进行了一项基于智能手机的研究,共有10名用户和3个远程定向和移动指南。基于繁忙城市条件的现实背景,我们对支持策略的现场分析提供了对野外可用性的细致见解,这是单独通过访谈和实验室实验无法实现的。我们进一步确定了歧视和取消乘坐的常见问题,进一步强调了在车辆交互任务中远程支持的重要性。我们的研究结果通过解决等待时间、故障情况(例如,错误的乘车识别)以及考虑实际系统限制和从起点到车辆到目的地旅行过程中用户需求的改进支持指南,为无障碍乘车服务的设计提供了信息。

“She was useful, but a bit too optimistic”: Augmenting Design with Interactive Virtual Personas “她很有用,但有点过于乐观”:用交互式虚拟人物角色增强设计

Personas have been widely used to understand and communicate user needs in human-centred design. Despite their utility, they may fail to meet the demands of iterative workflows due to their static nature, limited engagement, and inability to adapt to evolving design needs. Recent advances in large language models (LLMs) pave the way for more engaging and adaptive approaches to user representation. This paper introduces Interactive Virtual Personas (IVPs): multimodal, LLM-driven, conversational user simulations that designers can “interview,” brainstorm with, and gather feedback from in real time via voice interface. We conducted a qualitative study with eight professional UX designers, employing an IVP named "Alice" across three design activities: user research, ideation, and prototype evaluation. Our findings demonstrate the potential of IVPs to expedite information gathering, inspire design solutions, and provide rapid user-like feedback. However, designers raised concerns about biases, over-optimism, the challenge of ensuring authenticity without real stakeholder input, and the inability of the IVP to fully replicate the nuances of human interaction. Our participants emphasized that IVPs should be viewed as a complement to, not a replacement for, real user engagement. We discuss strategies for prompt engineering, human-in-the-loop integration, and ethical considerations for effective and responsible IVP use in design. Finally, our work contributes to the growing body of research on generative AI in design process by providing insights into UX designers’ experiences of LLM-powered interactive personas.
在以人为中心的设计中,人物角色被广泛用于理解和交流用户需求。尽管它们很实用,但由于它们的静态特性、有限的参与以及无法适应不断发展的设计需求,它们可能无法满足迭代工作流的需求。大型语言模型(llm)的最新进展为更具吸引力和适应性的用户表示方法铺平了道路。本文介绍了交互式虚拟人物(IVPs):多模态、llm驱动、会话用户模拟,设计师可以通过语音界面“采访”、头脑风暴和收集实时反馈。我们与8位专业的用户体验设计师进行了定性研究,雇佣了一位名叫“Alice”的IVP,涉及三个设计活动:用户研究、构思和原型评估。我们的研究结果证明了ivp在加速信息收集、激发设计解决方案和提供快速用户反馈方面的潜力。然而,设计师们对偏见、过度乐观、在没有真正利益相关者投入的情况下确保真实性的挑战以及IVP无法完全复制人类互动的细微差别提出了担忧。我们的与会者强调,ivp应该被视为对真正的用户参与的补充,而不是替代。我们讨论了在设计中有效和负责任地使用IVP的快速工程、人在环集成和伦理考虑的策略。最后,我们的工作通过提供对用户体验设计师在法学硕士支持的互动角色的经验的见解,为设计过程中生成式人工智能的研究做出了贡献。

Dog monitoring technologies are increasingly integrated into dog owners’ routines, yet the perceived impacts of these technologies on dogs and their owners remain underexplored. This study aimed to investigate the perceptions of dog owners (n = 86) regarding use and impacts of these technologies through a mixed-methods questionnaire. Qualitative content analysis was conducted to identify owners’ reasons for adopting dog monitoring technologies and their perceived impacts. Quantitative data were summarized descriptively and associations of perceived impacts with owner demographics, dog characteristics, technology characteristics and scores on the Monash Dog Owner Relationship Scale were assessed using mixed-effect logistic regression models. Five main themes were identified as reasons for adopting and using technologies: 1) monitoring dog safety, 2) monitoring dog behavior, 3) monitoring dog health or disease, 4) owner-related factors, and 5) miscellaneous reasons. Perceived positive impacts on dogs included improved care and increased off-leash opportunities, while negative impacts involved owners’ low trust in the technology’s reliability and concerns about dog behavioral issues and discomfort. Most owners identified a positive impact on themselves, including reduced anxiety and enhanced self-assessed pet parenting. Stress and financial concerns were mentioned as negative effects. No associations were found between quantitative variables and perceived positive or negative impacts. The findings underscore the importance of considering both the benefits and potential drawbacks of these technologies to ensure their ethical and effective integration into the lives of dogs and the humans who care for them.
狗监测技术越来越多地融入狗主人的日常生活,但这些技术对狗和主人的影响仍未得到充分探讨。本研究旨在通过混合方法问卷调查狗主人(n = 86)对这些技术的使用和影响的看法。进行定性内容分析,以确定主人采用狗监测技术的原因及其感知影响。对定量数据进行描述性总结,并使用混合效应逻辑回归模型评估感知影响与主人人口统计学、狗的特征、技术特征和莫纳什狗主人关系量表得分之间的关联。采用和使用技术的原因主要有五个:1)监测狗的安全,2)监测狗的行为,3)监测狗的健康或疾病,4)与主人有关的因素,以及5)其他原因。对狗的积极影响包括改善了对狗的照顾和增加了不拴狗绳的机会,而负面影响包括主人对技术可靠性的信任度较低,以及对狗的行为问题和不适的担忧。大多数主人认为这对他们自己产生了积极的影响,包括减少了焦虑,提高了对宠物养育的自我评估。压力和财务问题被认为是负面影响。数量变量与感知到的积极或消极影响之间没有关联。研究结果强调了考虑这些技术的好处和潜在缺点的重要性,以确保它们在道德和有效地融入狗和照顾它们的人类的生活中。

Perceived positive impacts on dogs included improved care and increased off-leash opportunities, while negative impacts involved owners’ low trust in the technology’s reliability and concerns about dog behavioral issues and discomfort. Most owners identified a positive impact on themselves, including reduced anxiety and enhanced self-assessed pet parenting. Stress and financial concerns were mentioned as negative effects. No associations were found between quantitative variables and perceived positive or negative impacts. The findings underscore the importance of considering both the benefits and potential drawbacks of these technologies to ensure their ethical and effective integration into the lives of dogs and the humans who care for them.</div></div>","PeriodicalId":54955,"journal":{"name":"International Journal of Human-Computer Studies","volume":"205 ","pages":"Article 103645"},"PeriodicalIF":5.1,"publicationDate":"2025-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145159550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Anxiety related to dental treatment is a common case among children and can cause serious problems. This study introduces a new distraction technique that utilizes a robotic companion to improve the clinical experience of children and reduce dental anxiety during procedures. The goal is to create an enjoyable and calming environment for pediatric patients by employing robots, encouraging positive behaviors, and cooperation. This approach aims to avoid the expensive and risky alternatives of sedation and general anesthesia. The study focuses on children aged 6 to 10 years and presents an experimental setup involving a humanoid robot, enabling a Wizard of Oz experiment. We compare the effectiveness of two robotic companions and two conventional behavior management methods in reducing dental anxiety. Four groups of patients are treated in different behavior management scenarios: (1) a dentist treating a child without assistance, (2) a dentist assisted by a tablet, (3) a dentist assisted by a humanoid robot, and (4) a dentist assisted by a humanoid robot equipped with a screen on its chest. The performances of the robotic systems are evaluated through patient and dentist questionnaires, as well as by measuring the patient’s pulse rate. The results of the experiments carried out with 120 children demonstrate the effectiveness of the proposed approach using socially assistive robots in dental treatment.
与牙科治疗相关的焦虑在儿童中很常见,并可能导致严重的问题。本研究介绍了一种新的分散注意力技术,利用机器人伴侣来改善儿童的临床体验,减少手术过程中的牙科焦虑。目标是通过使用机器人,鼓励积极的行为和合作,为儿科患者创造一个愉快和平静的环境。这种方法的目的是避免昂贵和危险的镇静和全身麻醉的替代品。该研究以6至10岁的儿童为对象,提出了一个涉及人形机器人的实验设置,实现了绿野仙踪的实验。我们比较了两种机器人同伴和两种传统行为管理方法在减少牙科焦虑方面的有效性。四组患者在不同的行为管理场景下进行治疗:(1)牙科医生在没有帮助的情况下治疗儿童,(2)牙科医生在平板电脑的辅助下治疗,(3)牙科医生在人形机器人的辅助下治疗,(4)牙科医生在胸部装有屏幕的人形机器人的辅助下治疗。机器人系统的性能是通过病人和牙医的问卷,以及通过测量病人的脉搏率来评估的。对120名儿童进行的实验结果表明,在牙科治疗中使用社交辅助机器人的方法是有效的。

This study is located in the Human-Centered Artificial Intelligence (HCAI) and focuses on the results of a user-centered assessment of commonly used eXplainable Artificial Intelligence (XAI) algorithms, specifically investigating how humans understand and interact with the explanations provided by these algorithms. To achieve this, we employed a multi-disciplinary approach that included state-of-the-art research methods from social sciences to measure the comprehensibility of explanations generated by a state-of-the-art machine learning model, specifically the Gradient Boosting Classifier (XGBClassifier). We conducted an extensive empirical user study involving interviews with 39 participants from three different groups, each with varying expertise in data science, data visualisation, and domain-specific knowledge related to the dataset used for training the machine learning model. Participants were asked a series of questions to assess their understanding of the model’s explanations. To ensure replicability, we built the model using a publicly available dataset from the University of California Irvine Machine Learning Repository, focusing on edible and non-edible mushrooms. Our findings reveal limitations in existing XAI methods and confirm the need for new design principles and evaluation techniques that address the specific information needs and user perspectives of different classes of artificial intelligence (AI) stakeholders. We believe that the results of our research and the cross-disciplinary methodology we developed can be successfully adapted to various data types and user profiles, thus promoting dialogue and address opportunities in HCAI research. To support this, we are making the data resulting from our study publicly available.
本研究定位于以人为中心的人工智能(HCAI),重点关注以用户为中心的常用可解释人工智能(XAI)算法的评估结果,具体调查人类如何理解这些算法提供的解释并与之互动。为了实现这一目标,我们采用了一种多学科的方法,其中包括来自社会科学的最先进的研究方法,以衡量由最先进的机器学习模型(特别是梯度增强分类器(XGBClassifier))生成的解释的可理解性。我们进行了广泛的经验用户研究,涉及对来自三个不同组的39名参与者的访谈,每个参与者在数据科学,数据可视化和与用于训练机器学习模型的数据集相关的领域特定知识方面具有不同的专业知识。参与者被要求回答一系列问题,以评估他们对模型解释的理解程度。为了确保可复制性,我们使用来自加州大学欧文分校机器学习存储库的公开数据集构建了模型,重点关注食用和非食用蘑菇。我们的研究结果揭示了现有人工智能方法的局限性,并确认需要新的设计原则和评估技术,以解决不同类别的人工智能(AI)利益相关者的特定信息需求和用户观点。我们相信,我们的研究成果和我们开发的跨学科方法可以成功地适应各种数据类型和用户概况,从而促进HCAI研究中的对话和解决机会。为了支持这一点,我们正在公开我们研究的数据。

As autonomous vehicles (AVs) reshape urban mobility, establishing effective communication between pedestrians and self-driving vehicles has become a critical safety imperative. This work investigates the integration of Smart Pole Interaction Units (SPIUs) as external human–machine interfaces (eHMIs) in shared spaces and introduces an innovative approach to enhance pedestrian–AV interactions. To provide subjective evidence on SPIU usability, we conduct a group design study (“Humans”) involving 25 participants (aged 18–40). We evaluate user preferences and interaction patterns using group discussion materials, revealing that 90% of the participants strongly prefer real-time multi-AV interactions facilitated by SPIU over conventional eHMI systems, where a pedestrian must look at multiple AVs individually. Furthermore, they emphasize inclusive design through multi-sensory communication channels—visual, auditory, and tactile signals—specifically addressing the needs of vulnerable road users (VRUs), including those with impairments. To complement these non-expert, real-world insights, we employ three leading Large Language Models (LLMs) (ChatGPT-4, Gemini-Pro, and Claude 3.5 Sonnet) as “experts” due to their extensive training data. Using the advantages of the multimodal vision-language processing capabilities of these LLMs, identical questions (text and images) used in human discussions are posed to generate text responses for pedestrian–AV interaction scenarios. Responses generated from LLMs and recorded conversations from human group discussions are used to extract the most frequent words. A keyword frequency analysis from both humans and LLMs is performed with three categories, Context, Safety, and Important. Our findings indicate that LLMs employ safety-related keywords 30% more frequently than human participants, suggesting a more structured, safety-centric approach. Among LLMs, ChatGPT-4 demonstrates superior response latency, Claude shows a closer alignment with human responses, and Gemini-Pro provides structured and contextually relevant insights. Our results from “Humans” and “LLMs” establish SPIU as a promising system for facilitating trust-building and safety-ensuring interactions among pedestrians, AVs, and delivery robots. Integrating diverse stakeholder feedback, we propose a prototype SPIU design to advance pedestrian–AV interactions in shared urban spaces, positioning SPIU as crucial infrastructure hubs for safe and trustworthy navigation.
随着自动驾驶汽车(AVs)重塑城市交通,在行人和自动驾驶汽车之间建立有效的沟通已成为一项至关重要的安全要务。本研究探讨了智能杆交互单元(SPIUs)作为共享空间外部人机界面(eHMIs)的集成,并引入了一种创新的方法来增强行人与自动驾驶汽车的交互。为了提供SPIU可用性的主观证据,我们进行了一项涉及25名参与者(18-40岁)的群体设计研究(“人类”)。我们使用小组讨论材料评估用户偏好和交互模式,发现90%的参与者强烈喜欢SPIU提供的实时多自动驾驶汽车交互,而不是传统的eHMI系统,行人必须单独查看多辆自动驾驶汽车。此外,他们强调通过多感官沟通渠道(视觉、听觉和触觉信号)进行包容性设计,特别满足弱势道路使用者(包括残疾人)的需求。为了补充这些非专家的、真实世界的见解,我们采用了三个领先的大型语言模型(llm) (ChatGPT-4、Gemini-Pro和Claude 3.5 Sonnet)作为“专家”,因为他们有广泛的训练数据。利用这些llm的多模态视觉语言处理能力的优势,在人类讨论中使用的相同问题(文本和图像)被提出,以生成行人与自动驾驶汽车交互场景的文本响应。从法学硕士产生的回答和从人类小组讨论中记录的对话被用来提取最常见的单词。来自人类和法学硕士的关键字频率分析分为三个类别:上下文、安全和重要。我们的研究结果表明,法学硕士使用安全相关关键词的频率比人类参与者高30%,这表明一种更结构化、更以安全为中心的方法。在法学硕士中,ChatGPT-4显示出优越的响应延迟,Claude显示出与人类反应更接近的一致性,而Gemini-Pro提供结构化和上下文相关的见解。我们在“人类”和“法学硕士”的研究结果表明,SPIU是一个很有前途的系统,可以促进行人、自动驾驶汽车和送货机器人之间的信任建立和安全互动。综合不同利益相关者的反馈,我们提出了一个SPIU原型设计,以促进共享城市空间中行人与自动驾驶汽车的互动,将SPIU定位为安全可靠导航的关键基础设施枢纽。

AI tools for supporting, or even fully automating, human decision-making have been proposed in a variety of domains, promising faster and better quality of decisions. However, for high-stakes and critical decisions, humans are still required in the decision-making process. Despite the need for human involvement, the research core centers mainly around the technical issues of AI, i.e. how to develop better performing machine learning (ML) models, setting aside the issue of designing, developing, and evaluating AI tools that are to be used in a human-AI context. This focus has led to a lack of experience and guidance of designing and developing AI tools that support their users in a decision-making context, keeping the human in the loop.
In this paper, we outline our work on designing, developing, and evaluating a transparent AI-based tool to be used by non-AI experts, namely healthcare professionals. The work carried out had two parallel tracks. One focused on testing and implementing a suitable ML technique for sepsis diagnostics based on real patient data and applying explainable AI (XAI) techniques on the results to better enable healthcare professionals to understand and trust the analysis results. The other track included an iterative design process for developing a user-centered, transparent, and trustworthy sepsis diagnostic tool, evaluating whether the generated XAI explanations were fit for purpose. We present the process applied for intertwining these tracks during a common multidisciplinary development process, providing guidance how to conduct a human-centered AI (HCAI) project. We discuss lessons learned, and outline future work for the development of HCAI tools to be used by non-AI experts.
用于支持甚至完全自动化人类决策的人工智能工具已经在各种领域提出,承诺更快,更好的决策质量。然而,对于高风险和关键的决策,仍然需要人类参与决策过程。尽管需要人类的参与,但研究核心主要围绕人工智能的技术问题,即如何开发性能更好的机器学习(ML)模型,撇开设计、开发和评估将在人类-人工智能环境中使用的人工智能工具的问题。这种关注导致缺乏设计和开发人工智能工具的经验和指导,这些工具在决策环境中支持用户,使人类处于循环中。在本文中,我们概述了我们在设计、开发和评估非人工智能专家(即医疗保健专业人员)使用的透明的基于人工智能的工具方面的工作。所进行的工作有两条平行的轨道。其中一个重点是测试和实施基于真实患者数据的败血症诊断的合适ML技术,并在结果上应用可解释的AI (XAI)技术,以更好地使医疗保健专业人员理解和信任分析结果。另一条轨道包括开发以用户为中心、透明且值得信赖的败血症诊断工具的迭代设计过程,评估生成的XAI解释是否适合目的。我们提出了在一个共同的多学科开发过程中应用这些轨道交织的过程,为如何开展以人为本的人工智能(HCAI)项目提供指导。我们讨论了经验教训,并概述了未来开发供非人工智能专家使用的HCAI工具的工作。
