Vibes That Emote: Eliciting Affect Through Vibrotactile Stimulation
摘要
Vibrotactile (VBT) haptic stimulators are commonly used in virtual reality (VR) applications to generate emotional responses, also known as affect, to enhance the immersive experience. However, despite its wide potential for application, there remains a significant gap in research, particularly in establishing a clear connection between the parameters of the stimulation, the resulting emotional responses, and the associated changes in electrocortical activity. As a result, the success rate in achieving the desired affect levels varies, and VBT-based actuators are still not mainstream despite being easily deployable and cheap. Understanding this relationship could enable a more systematic approach to deploying stimuli in VR environments, incorporating Brain-Computer Interfaces (BCI). This would improve the ability to predict and evoke the desired emotional responses, enhancing the repeatability of the process and making it more universally applicable. This chapter aims to review existing literature on the topic, highlight connections where possible, and explore strategies to bridge these factors to enhance the consistency of emotional responses induced by haptic stimulation in VR applications.
