目的 以信号检测论为切入点,探究将系统可靠性信息进行透明化设计后,其在不同系统可靠性和风险情境下对操作者的信任水平和对人机协同绩效的影响。方法 采用2(透明度)×2(风险)×3(可靠性)被试内设计,通过TNO信任任务收集了32位被试的数据,记录各条件下对自动化系统的信任水平、判断标准倾向和人机协同绩效,并对数据进行重复测量方差分析。结果 在不同可靠性水平和风险情境下,透明化设计产生的效果不同。相对于低透明化设计,当自动化系统可靠性较高时,高透明化设计可显著提升操作者对系统的主观信任评分、屈从率,更接近最优判断标准,带来更高的正确率增益、更小的人机最优绩效差异。风险水平影响人机协同绩效,高风险下的人机协同绩效显著低于低风险下人机协同绩效,并且当系统可靠性高时,操作者在高风险下对系统的屈从率、正确率增益较低风险下均显著下降。透明化设计可以改变不同风险下操作者的信任行为和绩效。高风险下,高透明度可显著提升操作者对系统的屈从率,减小与人机最优绩效的差异。结论 透明化设计有利于提高操作者的人机信任适配水平、优化决策判断标准、促进人机协同绩效的提升,尤其在系统高可靠性和高风险情境下,透明化设计的优... 相似文献

An obstacle detection task supported by ‘imperfect’ automation was used with the goal of understanding the effects of automation error types and age on automation reliance. Sixty younger and sixty older adults interacted with a multi-task simulation of an agricultural vehicle (i.e. a virtual harvesting combine). The simulator included an obstacle detection task and a fully manual tracking task. A micro-level analysis provided insight into the way reliance patterns change over time. The results indicated that there are distinct patterns of reliance that develop as a function of error type. A prevalence of automation false alarms led participants to under-rely on the automation during alarm states while over-relying on it during non-alarm states. Conversely, a prevalence of automation misses led participants to over-rely on automated alarms and under-rely on the automation during non-alarm states. Older adults adjusted their behaviour according to the characteristics of the automation similar to younger adults, although it took them longer to do so. The results of this study suggest that the relationship between automation reliability and reliance depends on the prevalence of specific errors and on the state of the system. Understanding the effects of automation detection criterion settings on human–automation interaction can help designers of automated systems to make predictions about human behaviour and system performance as a function of the characteristics of the automation. 相似文献

Previous studies showed performance benefits with correct automation, but performance costs when the automation was incorrect (i.e. provided an incorrect course of action), particularly as degrees of automation increased. Automation researchers have examined individual differences, but have not investigated the relationship between working memory and performance with various degrees of automation that is both correct and incorrect. In the current study, working memory ability interacted with automation reliability and degree of automation. Higher degrees of correct automation helped performance while higher degrees of incorrect automation worsened performance, especially for those with lower working memory. Lower working memory was also associated with more trust in automation. Results illustrate the interaction between degree of automation and individual differences in working memory on performance with automation that is correct and automation that fails. 相似文献

Function sharing is the simultaneous implementation of several functions by a single structural element. This article describes how the idea of function sharing can be used in a computational design procedure that produces efficient designs from modular designs. These ideas have been implemented as a computer program for the domain of mechanical devices that can be described functionally as a network of lumped-parameter idealized elements. 相似文献

The current article reports the results of three different studies which explored the relationship between the Perfect Automation Schema (PAS) and trust in a human–machine context. It was expected that PAS would be related to higher trust and higher performance expectations for automation. Studies 1 and 2 used a human-robot interaction simulator as the context for human-machine interaction and study 3 used an applied sample of F-16 pilots and their views of the Automatic Ground Collision Avoidance System (Auto-GCAS) which is an advanced automated safety system. Results from all three studies demonstrated that the high expectations facet of PAS had a positive relationship with trust, but not the all-or-none facet. These results suggest that the PAS as measured by high expectations may be a fruitful construct for researchers in the domain of trust in automation. 相似文献

Automated manufacturing cells are capable of producing different products using the same set of resources. This characteristic allows a more efficient use of resources, but makes the control of these systems more difficult and susceptible to errors. This article addresses the problem of routing control in an automated manufacturing cell that consists of three workstations, a transportation system, a feeding conveyor and a retrieving conveyor. In the modelling step, this article employs a systematisation of system and behavioural specifications modelling. This systematisation aims to minimise the impact caused by changes on system constitution and production specifications. In the synthesis step, the local modular control approach of the supervisory control theory is used to obtain the supervisors that match the specifications. In the implementation step, the systematic translation of the results obtained with the application of this theory into the application program to be implemented in the programmable logic controller that controls the cell occurs. The proposed approach in this study was tested and validated in a real manufacturing cell and the experimental results show the viability and success of this project. 相似文献

This study investigated effects of threshold setting in likelihood alarm systems (LASs) on safety, performance and participants’ mental representation of LASs. Three LASs were compared under two workload conditions. LASs had the same lower (first) threshold separating non-alerts from warnings but differed with regard to their higher (second) threshold dividing warnings from alarms. Behaviour, performance and trust were assessed. Participants of all three conditions responded to almost every alarm but only to parts of the warnings. Threshold setting affected safety, as the most liberal second threshold led to the highest joint human–machine sensitivity. Increasing workload decreased concurrent task performance. A negative correlation of trust in warnings and response rates to warnings reflected reliance and implies a mental representation of graduation of non-alerts. Results suggest that LAS threshold setting allows a precise guidance of users’ behaviour and show the importance of knowledge regarding users’ mental representation for the design of LASs. 相似文献

ABSTRACTTechnological solutions incorporating automated functionality have been seen as tools that can be used to reduce human error in both aviation and driving environments whilst bringing about improvements to operational safety and reduced accident rates. Historically, aviation has led the way, but over recent years, developments in the field of driving automation have accelerated rapidly. This paper looks more closely at what aviation may now learn from driving by assessing the underlying motivations and use of automation within their respective fields, as well as the differing design philosophies used to implement such systems. 相似文献

Health care users and patients are increasingly using online health communities to seek medical service, especially during the COVID-19 epidemic. The factors that determine the online trust between physicians and patients perplex the stakeholders for a long time. Based on the trust theory, this study explored the influence of physicians' personal quality and online reputation on patients' selection. A longitudinal panel data collection exercise, covering 11905 physicians on haodf. com, was conducted on May 20, 2018, May 22, 2019 and May 25, 2020. The random effect models are used to test our hypothesis. Results show that physicians' quality (competence, benevolence, and integrity) and online reputation (online reviews and online rating) can significantly affect patients' selection. Moreover, the physician's gender can enhance the influence of online reputation on patients' selection. As online healthcare community becomes an increasingly appealing channel for health, the frequency of the physician's quality information updating and the quality of online service are equally important to online physician-patient trust. 相似文献

This paper summarizes the state of art in quantum communication networks and trust management in recent years. As in the classical networks, trust management is the premise and foundation of quantum secure communication and cannot simply be attributed to security issues, therefore the basic and importance of trust management in quantum communication networks should be taken more seriously. Compared with other theories and techniques in quantum communication, the trust of quantum communication and trust management model in quantum communication network environment is still in its initial stage. In this paper, the core technologies of establishing secure and reliable quantum communication networks are categorized and summarized, and the trends of each direction in trust management of quantum communication network are discussed in depth. 相似文献

In mobile cloud computing, trust is a very important parameter in mobile cloudcomputing security because data storage and data processing are performed remotely inthe cloud. Aiming at the security and trust management of mobile agent system in mobilecloud computing environment, the Human Trust Mechanism (HTM) is used to study thesubjective trust formation, trust propagation and trust evolution law, and the subjectivetrust dynamic management algorithm (MASTM) is proposed. Based on the interactionexperience between the mobile agent and the execution host and the third-partyrecommendation information to collect the basic trust data, the public trust host selectionalgorithm is given. The isolated malicious host algorithm and the integrated trust degreecalculation algorithm realize the function of selecting the trusted cluster and isolating themalicious host, so as to enhance the security interaction between the mobile agent and thehost. Given algorithm simulation and verification were carried out to prove its feasibilityand effectiveness. 相似文献

Recent human-automation interaction research has confused concepts of automation and autonomy and has critiqued theories of automation in human-systems in terms of aspects of autonomy. This situation has led to inappropriate expectation for design and misdirected criticism of design methods. The situation is not new and has origins in historical human factors research. I differentiate the concepts of automation and autonomy with a new framework of agents. The framework is complemented by observations on characteristics of automated vs. autonomous systems, identification of error and failure modes, and formulation of a matrix of design constraints dictating possible applications of each type of agent. Discussion is provided on levels of automation, which have also been criticized in the literature, along with coverage of types of autonomy. A definition of autonomy is mutated throughout the paper to a form with utility for engineering. In general, demands of automated agents on the human-task-environment system should be absent from design of autonomous agents and design of automated systems is always automation-centric despite best efforts at human-centred approaches. Key requirements of design for autonomy include: agent viability in a target context, agent self-governance in goal formulation and fulfilment of roles, and independence in defined tasks performance. 相似文献
