During the last decade, touchless gestural interfaces have been widely studied as one of the most promising interaction paradigms in the context of pervasive displays. In particular, avatars and silhouettes have proved to be effective in making the touchless capacity of displays self-evident. In this paper, we focus on a child–display interaction approach to avatar-based touchless gestural interfaces. We believe that large displays offer an opportunity to stimulate children’s experiences and engagement; for instance, learning about art is very engaging for children but can bring a number of challenges. Our study aims to contribute to the literature on both pervasive displays and child–computer interaction by reporting the results of a study involving 107 children aged 2 to 10 years. The main purposes of this study were to discover: (1) whether an avatar (movable or immovable) provides interactions that are intuitive for children and therefore help to overcome so-called “affordance blindness”; (2) whether an avatar-based touchless interface makes children’s experiences engaging and enjoyable therefore improving recall of content provided through the interaction (learning about art). The study unveiled relevant outcomes in terms of affordance blindness and two-handed interactions. We provide evidence indicating that chronological age influences the style of child–avatar interaction. Finally, it is suggested that avatars could facilitate the development of new effective educational technologies for young children.

儿童显示互动:基于非接触式头像的大型显示界面的经验教训

在过去的十年中,非接触式手势界面已被广泛研究为普及显示环境中最有前途的交互范例之一。特别地,化身和剪影已被证明对于使显示器的非接触容量不言而喻是有效的。在本文中,我们专注于基于化身的非接触式手势界面的子显示交互方法。我们认为,大型显示器提供了一个激发儿童的经验和参与的机会;例如,对儿童的艺术学习非常有趣,但是会带来很多挑战。我们的研究旨在通过报道一项涉及107位2至10岁儿童的研究结果,为普及性展示和儿童与计算机互动的文献做出贡献。这项研究的主要目的是发现:(1)化身(可移动或不可移动)是否提供了对儿童直观的交互,因此有助于克服所谓的“负担失明”;(2)基于化身的非接触式界面是否使孩子们的体验引人入胜并且令人愉悦,因此提高了通​​过互动(学习艺术)提供的内容的回忆。该研究揭示了有关负担能力盲目性和双手互动的相关结果。我们提供的证据表明,按时间顺序排列的年龄会影响儿童与头像互动的方式。最后,建议化身可以促进针对幼儿的新型有效教育技术的发展。(2)基于化身的非接触式界面是否使孩子们的体验引人入胜并且令人愉悦,因此提高了通​​过互动(学习艺术)提供的内容的回忆。该研究揭示了有关负担能力盲目性和双手互动的相关结果。我们提供的证据表明,按时间顺序排列的年龄会影响儿童与头像互动的方式。最后,建议化身可以促进针对幼儿的新型有效教育技术的发展。(2)基于化身的非接触式界面是否使孩子们的体验引人入胜并且令人愉悦,因此提高了通​​过互动(学习艺术)提供的内容的回忆。该研究揭示了有关负担能力盲目性和双手互动的相关结果。我们提供的证据表明,按时间顺序排列的年龄会影响儿童与头像互动的方式。最后,建议化身可以促进针对幼儿的新型有效教育技术的发展。我们提供的证据表明,按时间顺序排列的年龄会影响儿童与头像互动的方式。最后,建议化身可以促进针对幼儿的新型有效教育技术的发展。我们提供的证据表明,按时间顺序排列的年龄会影响儿童与头像互动的方式。最后,建议化身可以促进针对幼儿的新型有效教育技术的发展。
