“…Previous studies evaluated other stimuli (music, movie, illumination, vibration and odor) based on physiological responses of the central nervous system [9][10][11][12][13][14][15][16][17][18][19][20][21]. First, listening to relaxing music has been found to increase power spectrum components of the α-wave [9] and θ-wave [10] of the EEG signal and to decrease cerebral blood flow in the frontal lobe [11].…”

“…Second, in a study of movie and image presentation, Aamir et al [12] reported that watching movie clip increased absolute α-wave power in occipital, parietal, frontal and motor regions compared to baseline. Additionally, Sakamoto et al revealed cerebral blood flow in the frontal lobe is an indicator of video comfort or discomfort [13]. Regarding illumination, several studies have examined color stimulus presentation [14][15][16].…”

“…Music stimuli, movie stimuli, illumination stimuli, odor stimuli and vibration stimuli (applied to the trunk) were presented. Previous studies evaluated participants' brain activity when presenting stimuli to a single sensory modality, based on physiological responses of the central nervous system [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. However, few studies have examined the combination thermal stimuli with stimulation of other sensory modalities.…”

The current study sought to examine differences in physiological responses to comfortable thermal stimuli applied to the soles of the feet during the simultaneous presentation of other sensory stimuli. As relaxing stimuli, underwater movie footage, classical music, light blue illumination, vibration of the trunk, and the odor of grapefruit oil were each presented simultaneously with a thermal stimulus. Electroencephalography of parietal and cerebral blood flow in the prefrontal cortex were measured. An increase in α-wave activity and a decrease in cerebral blood flow were found for all combinations of stimuli compared with baseline. Additionally, the results revealed differences in response speed depending on the stimulus presentation condition. However, the tendency suggesting a difference in response times depending on the stimulus condition was similar to that of the thermal stimulus alone. The results indicated that thermal stimulation has a substantial effect on the feeling of relaxation.

IntroductionThe three-dimensional movies are popular among today's generation. Following the success of the blockbuster movie Avatar, interest in 3D movies has increased significantly, leading to the production of more 3D movies. 3D televisions, 3D broadcasting and 3D Blu-ray movies also hit the market. More recently, virtual reality becomes a popular trend for consumers who want even more immersive 3D experiences. A few months ago Paramount Pictures launches the first virtual reality movie theater.Along with the rising popularity in 3D technologies, the biggest concern of creating 3D contents is to offer deeper and more meaningful experiences. Many works have shown that 3D images help users experience excitement, a feeling of presence, and enjoyment, and even performance advantages for depth-related tasks [1]. Despite the growing interest in 3D contents and technologies, few are concerned about viewers' perceptual and emotional responses to 3D stimuli.Much 3D related research is focused on technical factors, such as the fidelity of stereoscopic depth and reduction of visual discomforts while the viewer is watching 3D [2][3][4]. For example, subjective evaluation was used to compare visual fatigue induced by AbstractIn this research, we investigated on user's affective and physiological responses to the emotional movies. The emotional movies provide continuous feedback such as changes in saturation, brightness and contrast of the movie in response to users' emotional states. In the user study, the subjects watched the emotional movies, edited by fearful and joyful scenes, and presented in 2D and 3D formats. The subject's self-reported emotion responses and their physiological signals were analyzed. The results highlight the importance of scenes (such as, the color, tone, and brightness of the scene) than 2D or 3D format in understanding the impact of users' emotional responses. More physiological emotional changes, positive user responses and higher correlation rate between physiological and subjective responses were evident for joyful scene than fearful scene when presented in 3D format.

RESEARCHPage 2 of 17 KimOn the other hand, physiological measurements provide a more objective evaluation for studying visual fatigue induced by a 3D display [6]. For example, the study on influence of 3D TV based on physiological signals measured the viewers' emotional states [7,8]. Results showed a correlation between the effect of physiological responses and emotional states. This indicates that physiological responses can be potentially ample indicators of emotionally engaging 3D video.Human emotion is a complex phenomenon with both affective and physiological components. The affective component refers to the users' subjective feeling while the physiological component refers to the physiological...

Recent studies have shown that pleasant and unpleasant emotions could be detected through functional Near-Infrared Spectroscopy (fNIRS). This study investigates the prefrontal cortical activation in human subjects while they were viewing urban and garden scenes. A multi-channel continuous wave fNIRS system was used to record the prefrontal cortical activations from seven subjects. During the data collection, the subjects viewed 40 trials of video clips. In each trial, the subjects viewed a video of randomized urban or garden scenes for 30s followed by 30s of idle scene which showed a dark blue progress bar on black background on the screen. NIRS-SPM is employed to work out the changes of hemoglobin response and the prefrontal cortical activations were generated using group analysis based on the contrasts of urban versus idle, garden versus idle and urban versus garden. The activation for the contrast of urban versus garden showed an increase of oxy-hemoglobin on the right area of the prefrontal cortex with p <; 0.05. This preliminary result showed that the garden scene might provide a pleasant and less stressful experience as compared to the urban scene for subjects. This suggests the possibility of using a NIRS-based Brain-Computer Interface to detect subject preferences of different scenes.
