Virtual reality (VR) enables users to have a sense of presence and potentially facilitates effective learning. The research team developed Scale Worlds (SW), a virtual learning environment designed to help learners conceptualize size and scale through virtual shrinking and growing by tenfold increments and experiencing scientific entities at extreme scales. The present work investigated two crucial aspects of experiences in SW: the sense of presence and a novel self-scaling illusion. Participants experienced SW via two devices: a head-mounted display (HMD) with the absence of a virtual body and a Cave Automatic Virtual Environment (CAVE) where participants could see their own physical body. Results showed that participants reported higher levels of presence and more readily felt themselves shrinking and growing in SW-HMD than in SW-CAVE. Findings include factors that contributed to the sense of presence and self-scaling illusion in SW, and implications for designing those illusory experiences in VR across various applications and platforms.

摘要

Virtual reality (VR) enables users to have a sense of presence and potentially facilitates effective learning. The research team developed Scale Worlds (SW), a virtual learning environment designed to help learners conceptualize size and scale through virtual shrinking and growing by tenfold increments and experiencing scientific entities at extreme scales. The present work investigated two crucial aspects of experiences in SW: the sense of presence and a novel self-scaling illusion. Participants experienced SW via two devices: a head-mounted display (HMD) with the absence of a virtual body and a Cave Automatic Virtual Environment (CAVE) where participants could see their own physical body. Results showed that participants reported higher levels of presence and more readily felt themselves shrinking and growing in SW-HMD than in SW-CAVE. Findings include factors that contributed to the sense of presence and self-scaling illusion in SW, and implications for designing those illusory experiences in VR across various applications and platforms.
