标题： Planar or Spatial: Exploring Design Aspects and Challenges for Presentations in Virtual Reality with No-coding Interface

摘要： 虚拟现实（VR）的普及导致其越来越多地被用作一种沉浸式媒介来传递信息，这与其他VR体验如游戏和360度视频不同，因为它在丰富交互环境中分享信息。 然而，对于用户来说，创建引人入胜的VR演示仍然是一项具有挑战性和耗时的任务，阻碍了VR演示潜力的完全实现。 本研究旨在探索VR演示的潜力，分析用户的意见，并通过提供一个用户友好的无代码创作工具来研究这些方面。 通过对流行的演示软件进行检查并与七位专业人士进行访谈，我们确定了VR演示的五个设计方面和四个设计挑战。 基于这些发现，我们开发了VRStory，这是一个用于无需编码的演示创作的原型，以探索设计方面和解决挑战的策略。 VRStory提供了各种预定义和可定制的VR元素，以及用于布局设计、导航控制和资产生成的模块。 然后对12名参与者进行了用户研究，以调查他们对VRStory的意见和创作体验。 我们的结果表明，尽管承认VR中沉浸式和空间特性的好处，用户通常对传统的2D演示有一个一致的心理模型，可能仍然更喜欢VR中的平面和静态格式，以提高可访问性和有效的沟通。 最后，我们分享了未来VR演示工具开发的学习设计考虑因素，强调了促进沉浸式特性与确保可访问性之间平衡的重要性。 显示英文摘要

摘要： The proliferation of virtual reality (VR) has led to its increasing adoption as an immersive medium for delivering presentations, distinct from other VR experiences like games and 360-degree videos by sharing information in richly interactive environments. However, creating engaging VR presentations remains a challenging and time-consuming task for users, hindering the full realization of VR presentation's capabilities. This research aims to explore the potential of VR presentation, analyze users' opinions, and investigate these via providing a user-friendly no-coding authoring tool. Through an examination of popular presentation software and interviews with seven professionals, we identified five design aspects and four design challenges for VR presentations. Based on the findings, we developed VRStory, a prototype for presentation authoring without coding to explore the design aspects and strategies for addressing the challenges. VRStory offers a variety of predefined and customizable VR elements, as well as modules for layout design, navigation control, and asset generation. A user study was then conducted with 12 participants to investigate their opinions and authoring experience with VRStory. Our results demonstrated that, while acknowledging the advantages of immersive and spatial features in VR, users often have a consistent mental model for traditional 2D presentations and may still prefer planar and static formats in VR for better accessibility and efficient communication. We finally shared our learned design considerations for future development of VR presentation tools, emphasizing the importance of balancing of promoting immersive features and ensuring accessibility.
