虛擬實境中視角高度與互動體驗的探究-以《時空房間》為例

Abstract

自從虛擬實境技術的快速發展，虛擬實境應用百花齊放，對於創作者而言設立一個適合的交互的準則變得十分重要，但是在現有的被廣泛使用的虛擬實境設計準則中，強調的是體驗者能在虛擬空間的自由移動和互動，基本上只考慮了頭戴顯示器位置和轉動的互動，而忽略了對其視角高度的互動設計。\n因此一個針對視角高度設計的交互形式需要被設計出來，本研究便是針對在VR中如何利用頭戴顯示器的視角高度來設計交互，創作一個實驗性作品，以使用者控制站立、半蹲和坐在地面上的高度來線性控制虛擬實境中所處房間的時空變化，以3個不同的高度分別對應著老年、青年和幼年的時間，房間內裝飾也跟著變為不同年齡段時空的特點。在體驗中以視角控制與物體互動，發出相對應的聲音，而頭戴顯示器的高度控制著環境變化，房間及房間內物件會隨高度變化而進行改變大小的動畫、裝飾，同時室外天空也會隨高度變化而改變為清晨、正午、黃昏的變化。\n藉由展覽、觀察、反思，總結歸納出以下資料給相關領域的研究做參考：\n1.可以在沒有文字和圖示的情況下，根據體驗者視角高度進行交互操作。\n2.增加體驗的感知形式可增加沉浸感。

Since the rapid development of virtual reality technology and the proliferation of virtual reality applications, it is very important for creators to establish a suitable interaction criterion. Among the several widely used virtual reality design guidelines, the emphasis is on the experiencer to move and interact freely in the virtual space, but basically only considered the interaction of the position and rotation of the head-mounted display, neglecting the highly interactive design of its viewing angle. \nTherefore, a highly interactive design of its design needs to be designed. This study aims at how to use the perspective of the head-mounted display in VR to design interactions, create an experimental work, and use the user`s control to stand up, squat, and sit. The height above the ground linearly controls the temporal and spatial changes of the room in which the virtual reality is located. The three different heights correspond to the time of the old, the young, and the childhood, and the interior decoration of the room also follows the characteristics of space and time in different age groups. In the experience, the angle of view interacts with the object to make a corresponding sound, while the height of the head-mounted display controls the change of the environment, and the objects in the room and the room will change in size according to the height change, and the outdoor sky will also be decorated. Changes in altitude change to early morning, noon and evening changes. \nBy exhibition, observation and reflection, the following materials are summed up for reference in relevant research fields:\n1.The interactive operation can be conducted according to experiencers’ perspective height under the circumstance of non-text and non-graphics.\n2.Experiencing sensible form increasing can increase immersion.
