关于客观任务需求与随后对用户绩效的影响之间的联系,存在广泛的评估。然而,人类用户还体验到一系列与外部任务需求相关的情绪。有问题的,对情绪效价之间的联系知之甚少,与任务需求-性能轴相关的唤醒。在本文中,我们提出了一个关于这种互动影响的理论模型,使用三个维度:(1)情绪效价,(2)唤醒,(3)任务需求。该模型评估这些维度对用户性能的影响。它还可以识别用户的关键情绪状态,特别是那些导致负面性能影响的,以及可以积极影响表现的非关键情绪状态。最后,我们讨论了影响适应性系统的含义,该系统可以减轻关键情绪状态的影响,同时利用非关键情绪状态的好处。
为了有效地模拟性能并防止安全关键型人机系统中的错误,考虑用户的情绪状态是至关重要的,唤醒,和当前任务需求。所提出的模型可以对影响自适应系统中的临界状态和非临界状态进行分类。以负价为特征的状态,高唤醒,应避免过载,以促进高性能,尤其是在安全关键环境中。此外,本工作为保留和恢复非关键状态提供了建议,以确保最佳性能,并为培训提供了启示。
Extensive evaluations exist concerning the linkage between objective task demands and subsequent effects on user performance. However, the human user also experiences a range of emotions related to external task demands. Problematically, little is known about the associations between emotional
valence, and arousal associated with the task demand-performance axis. In this paper, we advance a theoretical model concerning such interactive influences using three dimensions: (1) emotional
valence, (2) arousal, and (3) task demand. The model evaluates the impact of these dimensions on user performance. It also identifies critical emotional user states, particularly those resulting in negative performance effects, as well as non-critical emotional states that can positively impact performance. Finally, we discuss the implications for affect-adaptive systems that can mitigate the impact of critical emotional states while leveraging the benefits of non-critical ones.
To effectively model performance and prevent errors in safety-critical human-machine systems, it is crucial to consider user states of emotional
valence, arousal, and the current task demand. The proposed model enables the classification of critical and non-critical states within affect-adaptive systems. States characterised by negative
valence, high arousal, and overload should be avoided to foster high performance, especially in safety-critical environments. Additionally, the present work offers recommendations for preserving and restoring non-critical states to ensure optimal performance and provides implications for training.
