An Exploratory Study of Using Interactive Volumetric Video in VR for Embodied Learning

Volumetric video (VV) has the potential to revolutionize traditional video-based learning (VBL) by offering immersive, 3D content that enhances student engagement and comprehension. However, the limited interactivity of current pre-recorded VV restricts its educational applications. To address this, we developed and evaluated an interactive VV viewing system that enables learners to engage with spatial interactive … Read more

Chameleon: Unobtrusive Substitution of Real-World Obstacles in VR with Risk-Level-Aware Adaptation

In VR environments, free movement in real space enhances immersion but increases the risk of collisions with real-world obstacles. Prior solutions investigated using substitute obstacles with context-related digital objects in VR but often treat all obstacles uniformly without considering their varying levels of risk. This oversight might result in reduced awareness for high-risk obstacles and … Read more

Volumivive: An Authoring System for Adding Interactivity to Volumetric Video

Volumetric video is a medium that captures the three-dimensional (3D) shape and movement of real-life objects or people. However, pre-recorded volumetric video is limited in terms of interactivity. We introduce a novel authoring system called Volumivive, which enables the creation of interactive experiences using volumetric video, enhancing the dynamic capabilities and interactivity of the medium. … Read more

Field Trial of a Tablet-based AR System for Intergenerational Connections through Remote Reading

Prior work has explored various technology designs to support intergenerational communications and connections through remote activities such as reading or play. However, few works have explored these technologies outside the family settings. In this work, we aimed to understand how technology can support social connectedness through remote activities, by investigating the use of a tablet-based … Read more

CoAR-Maze: empowering children’s collaborative tangible programming in augmented reality

As an effective way to develop children’s computational thinking, programming education has been intensively studied by scholars. Among them, tangible programming is more in line with children’s cognitive development and inherently supports collaborative learning. However, most of the tangible programming systems fall short in effectively stimulating active collaboration among children effectively. In this paper, we … Read more

“Be a Lighting Programmer”: Supporting Children Collaborative Learning through Tangible Programming System

In order to cultivate children’s computational thinking, researchers have developed many excellent programming systems. Among them, the tangible programming systems combined with graphic output have been widely accepted because of the intuitive input method and diversified visual feedback. However, few of them support collaborative learning or programming. Little is known about children’s experiences, emotional states … Read more
