ItemEvaluation of the impact of different levels of self-representation and body tracking on the sense of presence and embodiment in immersive VR( 2022) Guilherme Santos Gonçalves ; Miguel Correia Melo ; Luis Barbosa ; José Vasconcelos Raposo ; Maximino Bessa ; 5095 ; 5408 ; 6279 ; 6565 ; 6871The main goal of this paper is to investigate the effect of different types of self-representations through floating members (hands vs. hands feet), virtual full body (hands feet vs. full-body avatar), walking fidelity (static feet, simulated walking, real walking), and number of tracking points used (head hands, head hands feet, head hands feet hip) on the sense of presence and embodiment through questionnaires. The sample consisted of 98 participants divided into a total of six conditions in a between-subjects design. The HTC Vive headset, controllers, and trackers were used to perform the experiment. Users were tasked to find a series of hidden objects in a virtual environment and place them in a travel bag. We concluded that (1) the addition of feet to floating hands can impair the experienced realism (p = 0.039), (2) both floating members and full-body avatars can be used without affecting presence and embodiment (p > 0.05) as long as there is the same level of control over the self-representation, (3) simulated walking scores of presence and embodiment were similar when compared to static feet and real walking tracking data (p > 0.05), and (4) adding hip tracking overhead, hand and feet tracking (when using a full-body avatar) allows for a more realistic response to stimuli (p = 0.002) and a higher overall feeling of embodiment (p = 0.023).

ItemImmersive 360° video user experience: impact of different variables in the sense of presence and cybersickness( 2019) Miguel Correia Melo ; José Vasconcelos Raposo ; António Coelho ; David Gonçalves Narciso ; Maximino Bessa ; 6565 ; 5408 ; 5095 ; 3132 ; 6646Virtual Reality (VR) has been recently gaining interest from researchers and companies, contributing to the development of the associated technologies that aim to transport its users to a virtual environment by the stimulation of their senses. Technologies such as Head-Mounted Displays (HMD), capable of presenting 360° video in 3D, are becoming affordable and, consequently, more common among the average consumer, potentiating the creation of a market for VR experiences. The purpose of this study is to measure the influence of (a) video format (2D/monoscopic vs 3D/stereoscopic), (b) sound format (2D/stereo vs 3D/spatialized), and (c) gender on users’ sense of presence and cybersickness, while experiencing a VR application using an HMD. Presence and cybersickness were measured using questionnaires as subjective measures. Portuguese versions of the Igroup Presence Questionnaire for presence and the Simulator Sickness Questionnaire for cybersickness were used. Results revealed no statistically significant differences between (a) VIDEO and (b) SOUND variables on both senses of presence and cybersickness. When paired with (a) VIDEO, the independent variable (c) Gender showed significant differences on almost all subscales of presence. Results suggest that the widely acknowledged differences in spatial ability between genders were a major factor contributing to this outcome. © 2017 Springer-Verlag GmbH Germany
