Natural user interface (NUI) is considered a recent topic in human–computer interaction (HCI) and provides innovative forms of interaction, which are performed through natural movements of the human body like gestures, voice, and gaze. In the software development process, usability and user eXperience (UX) evaluations are a relevant step, since they evaluate several aspects of the system, such as efficiency, effectiveness, user satisfaction, and immersion. Thus, the goal of the authors’ systematic mapping study (SMS) is to identify usability and UX evaluation technologies used by researchers and developers in software with NUIs. Their SMS selected 56 papers containing evaluation technologies for NUI. Overall, the authors identified 30 different usability and UX evaluation technologies for NUI. The analysis of these technologies reveals most of them are used to evaluate software in general, without considering the specificities of NUI. Besides, most technologies evaluate only one aspect, Usability or UX. In other words, these technologies do not consider Usability and UX together. For future work, they intend to develop an evaluation technology for NUIs that fills the gaps identified in their SMS and combining Usability and UX.

自然用户界面的可用性和用户体验评估：系统的映射研究

自然用户界面（NUI）被认为是人机交互（HCI）的最新主题，并提供了创新的交互形式，这些交互形式是通过诸如手势，语音和注视之类的人体自然运动来执行的。在软件开发过程中，可用性和用户体验（UX）评估是一个重要步骤，因为它们评估了系统的多个方面，例如效率，有效性，用户满意度和沉浸感。因此，作者进行系统映射研究（SMS）的目标是确定研究人员和开发人员在具有NUI的软件中使用的可用性和UX评估技术。他们的SMS选择了56篇包含NUI评估技术的论文。总体而言，作者为NUI确定了30种不同的可用性和UX评估技术。对这些技术的分析表明，大多数技术通常都用于评估软件，而没有考虑NUI的特殊性。此外，大多数技术仅评估可用性或用户体验方面。换句话说，这些技术没有同时考虑可用性和UX。为了将来的工作，他们打算为NUI开发一种评估技术，以填补其SMS中确定的空白并结合可用性和UX。
