Educational videos are traditional means of communicating scientific findings to a broader audience. Nowadays, they are also a very common medium in distant teaching. However, creating videos using the existing software tools can be very challenging for inexperienced users. Also, the student’s engagement in standard videos is often very limited as the experience and exploration of the presented phenomena is indirect and far from being interactive. To overcome this, we propose a novel tool, called VRdeo, for creating and presenting educational material that utilizes the advantages of virtual reality (VR). Each stage of the production is represented by an operating mode, where the user acts in a predefined role. VRdeo is a versatile platform that enables tutors to immerse into the virtual scene, explore 3D models of scientific data, and record a narrated story where the tutor is an active element, represented by a virtual avatar. The recording can be exported as a virtual scene. The observers (e.g., students) can then enter such a scene where they can move around and have several options for replaying and interacting with the tutor’s story. In cases when the observer cannot use a virtual reality device, VRdeo enables to generate a traditional 2D video as well. To evaluate VRdeo, we asked several experts in diverse fields for their feedback and conducted a user study with students, which gave us valuable information about its usefulness for both creating and consuming the narrated stories.

VRdeo:使用虚拟现实为异步师生交流创建引人入胜的教育材料

教育视频是向更广泛的受众传播科学发现的传统方式。如今,它们也是远程教学中非常常见的媒介。但是,对于没有经验的用户来说,使用现有的软件工具创建视频可能非常具有挑战性。此外,学生对标准视频的参与通常非常有限,因为对所呈现现象的体验和探索是间接的,远非互动。为了克服这个问题,我们提出了一种名为 VRdeo 的新工具,用于创建和展示利用虚拟现实 (VR) 优势的教育材料。生产的每个阶段都由一种操作模式表示,其中用户扮演预定义的角色。VRdeo 是一个多功能平台,使导师能够沉浸在虚拟场景中,探索科学数据的 3D 模型,并记录一个讲述的故事,其中导师是一个活跃的元素,以虚拟化身为代表。录音可以导出为虚拟场景。观察者(例如,学生)然后可以进入这样一个场景,在那里他们可以四处走动,并有几个选项来重播和与导师的故事互动。如果观察者无法使用虚拟现实设备,VRdeo 也可以生成传统的 2D 视频。为了评估 VRdeo,我们询问了不同领域的几位专家的反馈,并与学生一起进行了用户研究,这为我们提供了有关其对创建和消费叙述故事的有用性的宝贵信息。学生)然后可以进入这样一个场景,在那里他们可以四处走动,并有多种选择来重播和与导师的故事互动。如果观察者无法使用虚拟现实设备,VRdeo 也可以生成传统的 2D 视频。为了评估 VRdeo,我们询问了不同领域的几位专家的反馈,并与学生进行了用户研究,这为我们提供了有关其在创建和消费叙述故事方面的有用性的宝贵信息。学生)然后可以进入这样一个场景,在那里他们可以四处走动,并有多种选择来重播和与导师的故事互动。如果观察者无法使用虚拟现实设备,VRdeo 也可以生成传统的 2D 视频。为了评估 VRdeo,我们询问了不同领域的几位专家的反馈,并与学生一起进行了用户研究,这为我们提供了有关其对创建和消费叙述故事的有用性的宝贵信息。
