Increasing Presence in Virtual Reality with a Vibrotactile Grid Around the Head

Abstract

A high level of presence is an important aspect of immersive virtual reality applications. However, presence is difficult to achieve as it depends on the individual user, immersion capabilities of the system (visual, auditory, and tactile) and the concrete application. We use a vibrotactile grid around the head in order to further increase the level of presence users feel in virtual reality scenes. In a between-groups comparison study the vibrotactile group scored significantly higher in a standardized presence questionnaire compared to the baseline of no tactile feedback. This suggests the proposed prototype as an additional tool to increase the level of presence users feel in virtual reality scenes.

Persuasive Vibrations: Effects of Speech-Based Vibrations on Persuasion, Leadership, and Co-Presence During Verbal Communication in VR

“…At the end of the simulation, participants were asked to identify who they thought was the leader and they chose the participant with a higher degree of immersion. As discussed in the previous paragraph on co-presence, haptic feedback appears to have a positive effect on presence (e.g., [12,32,36,39,44,63]), so that it might in turn positively affect leadership.…”

“…The results suggest a higher sense of co-presence when vibrotactile feedback was presented to users. Vibrotactile feedback also seem to increase the sense of presence (e.g., [12,22,32]). For instance in a study by Garcia et al [22], participants wore a vest containing vibrotactile actuators and received or did not receive feedback when they collided with avatars in a VR scenario.…”

Perception of Spatialized Vibrotactile Impacts in a Hand-Held Tangible for Virtual Reality

“…Vibrotactile feedback (VF) is a popular haptic feedback modality for virtual reality (VR) interaction because it combines relatively low technological complexity in its implementation with a wide variety of achievable haptic effects [5]. There is evidence for a positive impact of VF on many success metrics for interactions with virtual environments (VEs), such as improved task performances [2], improved user immersion [2], increased perceived realism [17] and increased presence [6,12]. VF can be used to communicate both physical cues relating to the VE (e.g.…”

“…Conversely, localized VF through multiple actuators is widely used to convey spatial information to the user, in particular in wearables (e.g. [5,11,12]) and surface haptics (e.g. [15]).…”

Исследования Эффекта Присутствия В Виртуальной Реальности: Современное Состояние И Перспективы

“…В одном из исследований авторы ссылаются на статью [Nacke, Lindley, 2008], в которой описаны и субъективные оценки, и психофизиологические показатели присутствия. Они указывают на отсутствие связи показателей популярного опросника Presence Questionnaire и психофизиологических характеристик, ставя под сомнение валидность самооценочных методов измерения [Kaul, Meier, Rohs, 2017].…”
