Multi-modal Physiological Signals based Fear of Heights Analysis in Virtual Reality Scenes

Fear of heights (FoH) analysis and its association to physiological signals can better help understand people's emotion and quantify human's behaviour, which have been found important in many applications, such as disease analysis, affective computing, etc. Existing studies are mainly on how to alleviate FoH while little literature on FoH analysis has been reported in the past. In this paper, we present the studies of correlation on FoH to multi-modal physiological signals in the virtual reality (VR). To stimulate the FoH to participants, 4 types of VR scenarios that consist of the virtual scene of the VR game "Richie's plank
