Human cognition and emotion can be affected by subliminal visual stimulus. Does sustained subliminal auditory stimulus (SAS) have the similar effect? In this study, the speech sound “Be happier” was used as the SAS, and the power-to-take game was used as the experimental task to investigate the effect of SAS on human emotion. 34 subjects were randomly divided into control group and experiment group...
Wireless physiological/neurological monitoring in virtual reality (VR) offers a unique opportunity for unobtrusively quantifying human responses to precisely controlled and readily modulated VR representations of health care environments. Here we present such a wireless, light-weight head-mounted system for measuring electrooculogram (EOG) and electroencephalogram (EEG) activity in human subjects...
Immersive and multimodal sensory feedback was implemented to improve neurorehabilitation movement training. A major aspect of feedback is to reflect back the patient's psychophysiological state into the environment, and also to use this as a guidance mechanism as to how events within the virtual environment unfold. The virtual environment was constructed using haptic, visual and acoustic primitives...
A visual display of stripes was used to examine cardiovagal response to motion sickness. Heart rate variability (HRV) was investigated using dynamic methods to discern instantaneous fluctuations in reaction to stimulus and perception-based events. A novel point process adaptive recursive algorithm was applied to the R-R series to compute instantaneous heart rate, HRV, and high frequency (HF) power...
