The purpose of requirements engineering (RE) is to make sure that the expectations and needs of the stakeholders of a software system are met. Emotional needs can be captured as emotional requirements that represent how the end user should feel when using the system. Differently from functional and quality (non-functional) requirements, emotional requirements have received relatively less attention from the RE community. This study is motivated by the need to explore and map the literature on emotional requirements. The study applies the systematic mapping study technique for surveying and analyzing the available literature to identify the most relevant publications on emotional requirements. We identified 34 publications that address a wide spectrum of practices concerned with engineering emotional requirements. The identified publications were analyzed with respect to the application domains, instruments used for eliciting and artefacts used for representing emotional requirements, and the state of the practice in emotion-related requirements engineering. This analysis serves to identify research gaps and research directions in engineering emotional requirements. To the best of the knowledge by the authors, no other similar study has been conducted on emotional requirements.

翻译：需求工程（RE）的目的是确保软件系统利益相关者的期望和需求得到满足。情感需求可被捕获为表示最终用户在使用系统时应如何感受的情感需求。与功能需求和质量（非功能）需求不同，情感需求在RE社区中受到的关注相对较少。本研究旨在探索和映射关于情感需求的文献。研究采用系统性映射研究方法，对现有文献进行调研和分析，以确定情感需求领域最具相关性的出版物。我们识别出34篇涉及情感需求工程广泛实践的出版物。从应用领域、用于获取情感需求的工具和用于表示情感需求的工件，以及情感相关需求工程的实践现状等方面对这些出版物进行了分析。该分析有助于识别情感需求工程中的研究空白和研究方向。据作者所知，目前尚无其他类似的情感需求研究。
