理解沉浸式體驗中使用者的認知狀態轉變

Abstract

傳統上，對於使用者在沉浸式環境中主觀體驗的研究，通常集中於存在感，也就是身處於虛擬環境的感覺。我們建議將認知和感知分開，以便在現實與虛擬之間界限的日益模糊的未來，更好的理解更多樣化沉浸式體驗中使用者的主觀體驗。我們以「存在感」來描述使用者的感知體驗，並引入「認知狀態」，即指使用者相信自己正在與物理世界或虛擬世界互動的信念，來描述使用者的認知系統。我們假設使用者的認知狀態會在沉浸式體驗中轉變。我們設計了一個包含一系列高和低保真度感官線索的30分鐘密室逃脫體驗，來探究使用者的認知轉變及其誘發因素。通過對36名參與者的主題分析結果，我們概述了影響使用者認知轉變的六個因素：虛擬可信度、空間意識、感知、保真度、期望和任務順序，並提出了六條在設計沉浸式體驗上，建立使用者虛擬認知狀態的原則。

Traditionally, the study of users’ subjective experiences in immersive environments has typically focused on presence, which is the sense of being there. Considering the evolving forms of immersive experiences and the increasingly blurred boundaries between reality and virtuality, we suggest separating cognition and perception to better understand users’ subjective experiences. We retain “presence” to describe users’ perceptual experiences and introduce “cognitive state,” i.e., believing in either reality or virtuality, to describe the users’ cognitive systems. We hypothesize that users’ cognitive states will transition during immersive experiences. We design an experiment consisting of a series of sensory cues with high and low fidelity in a 30-minute escape room experience to probe the user’s cognitive transitions and the inducing factors. From the thematic analysis result of 36 participants, we outline the six factors affecting the user’s cognitive transitions: virtual plausibility, spatial awareness, sensation, fidelity, expectation, and task order, offering six guidelines for establishing users’ virtual cognitive state in an immersive experience.
