虚拟现实（VR）社区的主要目标是构建具有无缝和自然交互的完全沉浸式和现场诱导环境。为了实现这一目标，研究人员正在研究如何最好地直接使用我们的手与虚拟环境进行交互。这一领域的大多数研究都要求参与者执行重复性任务。在这篇文章中，我们调查，如果这些研究的结果转化为一个真实的应用程序和游戏般的经验。我们设计了一个虚拟密室，参与者可以与各种物体进行互动，以收集线索并完成谜题。在一项受试者之间的研究中，我们研究了两种输入方式（控制器与手跟踪）和两种抓取可视化（连续跟踪的手与抓取时消失的虚拟手）对所有权，现实主义，效率，享受和存在的影响。我们的结果表明，与控制器相比，使用手跟踪时，所有权，现实主义，享受和存在增加。在抓握过程中可视化跟踪的手导致我们的所有权问题之一和我们的享受问题之一的更高的评级相比，有虚拟的手在抓握过程中消失，这在许多应用程序中是常见的。我们还证实了两项研究的一些主要结果，这两项研究在更现实的游戏场景中具有重复设计，可能更接近典型的用户体验。
A primary goal of the Virtual Reality (VR) community is to build fully immersive and presence-inducing environments with seamless and natural interactions. To reach this goal, researchers are investigating how to best directly use our hands to interact with a virtual environment using hand tracking. Most studies in this field require participants to perform repetitive tasks. In this article, we investigate if results of such studies translate into a real application and game-like experience. We designed a virtual escape room in which participants interact with various objects to gather clues and complete puzzles. In a between-subjects study, we examine the effects of two input modalities (controllers vs. hand tracking) and two grasping visualizations (continuously tracked hands vs. virtual hands that disappear when grasping) on ownership, realism, efficiency, enjoyment, and presence.Our results show that ownership, realism, enjoyment, and presence increased when using hand tracking compared to controllers. Visualizing the tracked hands during grasps leads to higher ratings in one of our ownership questions and one of our enjoyment questions compared to having the virtual hands disappear during grasps as is common in many applications. We also confirm some of the main results of two studies that have a repetitive design in a more realistic gaming scenario that might be closer to a typical user experience.
