剪影游戏：一种观察VR中玩家的交互式单向镜像方法
Silhouette Games: An Interactive One-Way Mirror Approach to Watching Players in VR
摘要：
观看其他人玩游戏是数字游戏的一个关键因素，也是游戏用户研究的一个重要方面。然而，旁观在虚拟现实中并不流行，因为这样的游戏强烈地依赖于一个人的临场感。换句话说，盔装显示器在玩家和观众之间形成了一道屏障。我们贡献了一种替代观看方法，包括两个主要组成部分：一个动态视锥台，从当前观众的位置和一个单向镜在屏幕前渲染游戏场景。这面镜子，加上我们的轮廓算法，可以看到玩家的反映在虚拟世界中的正确位置。探索性调查强调观众在我们的设置中的整体积极体验。特别是，参与者享受他们通过物理重新定位探索虚拟环境的能力，并在对象操作过程中观察混合播放器。除了要求更大的屏幕外，参与者还表达了与玩家互动的强烈需求。因此，我们建议利用我们的技术作为基础，以新颖的游戏体验为首要目标，将被动的观众转变为搭配的玩家。
英文摘要：
Watching others play is a key ingredient of digital games and an important aspect of games user research. However, spectatorship is not very popular in virtual reality, as such games strongly rely on one's feelings of presence. In other words, the head-mounted display creates a barrier between the player and the audience. We contribute an alternative watching approach consisting of two major components: a dynamic view frustum that renders the game scene from the current spectator position and a one-way mirror in front of the screen. This mirror, together with our silhouetting algorithm, allows seeing the player's reflection at the correct position in the virtual world. An exploratory survey emphasizes the overall positive experience of the viewers in our setup. In particular, the participants enjoyed their ability to explore the virtual surrounding via physical repositioning and to observe the blended player during object manipulations. Apart from requesting a larger screen, the participants expressed a strong need to interact with the player. Consequently, we suggest utilizing our technology as a foundation for novel playful experiences with the overarching goal to transform the passive spectator into a collocated player.
