| 中文摘要 | With the popularization of the internet and the wide application of intelligent assistive technologies, education has broken through the restrictions of geography and time, which provides more possibilities to meet the diverse needs of students with disabilities in educational approaches due to individual differences. Education informationization promotes the effective utilization of smart terminal devices by people with disabilities, enhancing their opportunities for inclusive education and self-learning abilities. Currently, mainstream smart terminals such as smartphones and computers, by installing corresponding applications, not only provide convenience for the lives of able-bodied people, but their popularity and convenience also provide support for people with disabilities learning and and communication. However, mainstream smart terminals still adopt interactive technologies such as keyboard input and touch screen input that are suitable for hand operation, requiring users to perform fine motor on the interface with their hands. This poses a challenge for those with upper body motor impairments who have difficulty using their hands. Therefore, in the context of education informationization, this paper aims to provide more practical assistive technology support for the education and development of individuals with motor disabilities, stimulating their intrinsic potential, and effectively enhancing their self-directed learning ability and self-confidence. This article comprehensively applies qualitative and quantitative research methods, focusing on the perspective of user participation, and studies input assistive technologies suitable for upper body motor impairments to use intelligent devices. Considering the diversity of hand interaction abilities among individuals with upper body motor impairment, this article focuses on the following three sub studies to explore alternative interacting solutions based on their increasing difficulty in text input. The first research proposed adding a screen mapping function to the standard QWERTY keyboard, aiming to improve text input efficiency in single-hand operation scenarios by reducing the allocation of attention resources during input. Through eye-tracking analysis, we found that the new interacting method could reduce the input time by about 15% compared to the original method, and the text input time significantly shortened with increasing practice sessions. Therefore, after the new interaction habit is established and the text input efficiency of the two input methods is the same, the new keyboard interaction method can save 15% in text input efficiency. The second research focuses on the interaction experience, emotional response, and cognitive process of Augmentative and Alternative Communication (AAC) systems users with the high-tech AAC multimodal text generation system proposed by recent researchers. The aim is to explore the potential for improving communication abilities and social interaction opportunities for individuals with motor impairments through optimized text input interactions. The results show that the system is stability, significantly reducing the number of keystrokes required for users to input text using a keyboard, and enhancing user satisfaction and acceptance of the text generation system. This provides suggestions for improving and optimizing systems to better align with user interaction habits. The third research focuses on individuals with dystonia, a type of motor impairment, and employs the guessability methodology to explore users’ interacting preferences with natural gesture interacting technologies. The results show that individuals with dystonia have their own specific preferences due to abnormal facial muscle tone, and deriving head gestures set. The findings of this study provide useful guidance for the universal design of natural interaction technologies for smart devices. This paper contributes to a more user-friendly interacting between individuals with upper-body motor impairments and mainstream smart devices, enhancing the interaction experience and improving the utilization rate of smart terminals. This not only promotes equal access to intelligent technology for diverse groups, including individuals with disabilities, but also helps optimize teaching methods, enhance the self-directed learning ability of individuals with impairments, and promote their physical and mental development. |
| 英文摘要 | 随着互联网的普及与智能辅助技术的广泛应用，教育已突破地域与时空的限制，这为满足残障学生因个体差异对教育方式的多样化需求，实施个性化的教育支持策略，提供了更多可能性。教育信息化推动残障人士对智能终端设备的有效利用，进而提升其享受普惠教育资源的机遇，增强其自主学习能力。当前，诸如智能手机，电脑等主流智能终端通过安装相应的应用程序，不仅为健全人的生活提供了便利，其普及性和便捷性也为障碍者提供很好的 学习支持和沟通辅助。然而，主流智能终端仍然采用键盘输入和触摸屏输入等适用于双手操作的交互技术，用户需要使用手部在界面上进行精细化动作。 这对手部不便的上半身运动障碍者而言，存在无障碍使用挑战。故而，在教育信息化的时代背景下，本文致力于为运动残障者的教育与发展提供更具实用性的辅助技术支持，激发障碍学生的内在潜能，从而有效促进其自主学习的效果与自我认同的提升。 本文综合运用定性与定量研究方法，聚焦于用户参与视角，研究适合上半身运动障碍者使用智能设备的输入辅助技术。考虑到上半身运动障碍者的手部交互能力多样性，本文根据其对文本输入能力由易到难的程度递进，聚焦以下三个子研究，深入探索替代交互方案。 研究一提出在现有的标准 QWERTY 键盘上增加键盘操作区域屏幕映射功能，通过减少输入中的注意力资源分配进而提高单手操作情景下文本输入效率。本研究通过眼动追踪分析发现，新的交互方式比原方式少了占用 15% 左右的注意资源的路径用时，且文本输入用时随练习次数增加显著缩短。因此，当新的交互习惯建立后，两种输入方式下文本输入效率相同时，新的键盘交互方式文本输 入效率可以节省15% 。研究二关注辅助沟通系统 （Augmentative and Alternative Communication，AAC）用户对近期研究者提出的高技术 AAC 多模态文本生成系统的交互体验，情感反应和认知过程，探究通过优化文本输入交互方式改善运动障碍者沟通能力，增进其社会交往机率。研究结果显示该系统具有良好的稳定性，大大节省了用户使用键盘输入的按键次数并提高了用户对文本生成系统的满意度和接受度，为改进和优化沟通系统更贴近用户交互习惯提供建议。研究三以运动障碍类型之一的肌张力障碍者为中心，采用最大化猜想方法探索该群体利用基于身体姿势与智能手机自然交互技术的交互偏好。结果显示，肌张力障碍者因其面部肌张力异常，交互姿势的选择有自己的特定偏好，并得出了一套交互头势集。本研究的发现为智能终端自然交互技术的通用设计提供了有益的指导。 本研究有助于上半身运动障碍者与主流智能设备之间实现更加人性化的交互，提升交互体验，提高智能终端的使用率。这不仅能促进包括残障者在 内的多样化群体平等使用智能技术，也有助于优化教学方式，提升障碍者自主学习能力和学习成效，促进其身心发展。 |
