In this article, we compare three different input technologies (gamepad, vision-based motion controls, room-scale) for an interactive virtual reality (VR) environment. The overall system is able to visualize (open) data from multiple online sources in a unified interface, enabling the user to browse and explore displayed information in an immersive VR setting. We conducted a user interaction study (\(n=24\); \(n=8\) per input technology, between-group design) to investigate experienced workload and perceived flow of interaction. Log files and observations allowed further insights and comparison of each condition. We have identified trends that indicate user preference of a visual (virtual) representation, but no clear trends regarding the application of physical controllers (over vision-based controls), in a scenario that encouraged exploration with no time limitations.

虚拟现实中的开放数据探索：输入技术的比较研究

在本文中，我们针对交互式虚拟现实（VR）环境比较了三种不同的输入技术（游戏手柄，基于视觉的运动控件，房间比例）。整个系统能够在统一界面中可视化（打开）来自多个在线源的数据，使用户能够在沉浸式VR设置中浏览和浏览显示的信息。我们进行了用户交互研究（\（n = 24 \）；\（n = 8 \）每种输入技术，组间设计），以研究经验丰富的工作量和感知的交互流。日志文件和观察结果允许进一步了解和比较每种情况。我们已经确定了一些趋势，这些趋势指示用户对视觉（虚拟）表示的偏爱，但没有明确的趋势涉及物理控制器（基于视觉的控件），在无时间限制的情况下鼓励探索。
