Abstract

Typing tasks are basic interactions in a virtual environment (VE). The presence of uppercase letters affects the meanings of words and their readability. By typing uppercase letters on a QWERTY keyboard, the layers can be switched using a modifier key. Considering that VE controllers are typically used in a VE, this input method can result in user fatigue and errors. Thus, this study proposed new alternative interactions for the modifier key input and compared their typing performance and user experience. In an experiment, 30 participants were instructed to type 10 sentences using different typing interaction methods (shift, long press, and double-tap) on a virtual keyboard in a VE. The typing speed, error rate, and number of backspace inputs were measured to compare typing performance. Upon the completion of the typing task, the usability, workload, and sickness associated with each typing method were evaluated. The results showed that the double-tap method exhibited significantly higher typing speed, error rate, ease of use, satisfaction, and workload. This result is consistent with those of previous studies demonstrating that selection tasks were more efficient with fewer hand movements. Thus, this study implies that the double-tap method can be considered as a potential typing interaction for the VEs instead of the traditional method using the shift as a modifier key. Therefore, this study is expected to contribute to the design and development of user-friendly interactions.
比较虚拟现实中的大写输入法:修改键与其他方法
打字任务是虚拟环境(VE)中的基本互动。大写字母的存在会影响单词的含义和可读性。在 QWERTY 键盘上键入大写字母后,可以使用修改键切换层次。考虑到虚拟现实控制器通常在虚拟现实中使用,这种输入方法可能会导致用户疲劳和错误。因此,本研究为修改键输入提出了新的替代交互方式,并比较了它们的输入性能和用户体验。在一项实验中,30 名参与者在虚拟环境的虚拟键盘上使用不同的键入交互方法(移位、长按和双击)键入 10 个句子。通过测量打字速度、错误率和退格输入次数来比较打字性能。完成键入任务后,对每种键入方法的可用性、工作量和不适感进行了评估。结果显示,双击法的打字速度、出错率、易用性、满意度和工作量都明显更高。这一结果与之前的研究结果一致,即选择任务时手部动作越少效率越高。因此,这项研究表明,双击法可被视为虚拟电子工程师潜在的打字交互方式,而不是使用 shift 作为修改键的传统方法。因此,本研究有望为设计和开发用户友好型交互做出贡献。

期刊介绍: The International Journal of Human-Computer Studies publishes original research over the whole spectrum of work relevant to the theory and practice of innovative interactive systems. The journal is inherently interdisciplinary, covering research in computing, artificial intelligence, psychology, linguistics, communication, design, engineering, and social organization, which is relevant to the design, analysis, evaluation and application of innovative interactive systems. Papers at the boundaries of these disciplines are especially welcome, as it is our view that interdisciplinary approaches are needed for producing theoretical insights in this complex area and for effective deployment of innovative technologies in concrete user communities. Research areas relevant to the journal include, but are not limited to: • Innovative interaction techniques • Multimodal interaction • Speech interaction • Graphic interaction • Natural language interaction • Interaction in mobile and embedded systems • Interface design and evaluation methodologies • Design and evaluation of innovative interactive systems • User interface prototyping and management systems • Ubiquitous computing • Wearable computers • Pervasive computing • Affective computing • Empirical studies of user behaviour • Empirical studies of programming and software engineering • Computer supported cooperative work • Computer mediated communication • Virtual reality • Mixed and augmented Reality • Intelligent user interfaces • Presence ...
