In this study we investigated facial electromyographic (EMG) responses to vocal affect expressions. We also measured emotion-related action tendencies by requesting the subjects indicate their tendency approach or withdraw from person uttering stimulus word. addition, emotional contagion (EC) was with a questionnaire-based scale. The results showed that hearing expression of anger increased EMG activity in subjects' brow region more than contentment. contrast, contentment activated...

New methods for unobtrusive monitoring of computer users' emotion psychophysiology are very much needed in human-computer interaction research. The present aim was to study heart rate changes during emotionally provocative stimulation. Six-second long auditory, visual, and audiovisual negative, neutral, positive stimuli were presented 24 participants. Heart responses measured with a regular office chair embedded electromechanical film (the EMFi chair) traditional earlobe photoplethysmography...

Decades of research in environmental psychology have shown that contact with natural environments has restorative, stress-ameliorating effects. At present, researchers the emerging field virtual are studying whether these restorative health effects can be reproduced simulated environments, raising new possibilities for preventive healthcare and therapy. This paper aims to synthesize earlier on restoration nature, including theory, measurement, modalities. Restoration theories were reviewed...

A prototype of friction-based horizontally rotating fingertip stimulator was used to investigate emotional experiences and behavioral responses haptic stimulation. The rotation style 12 different stimuli varied by burst length (i.e., 20, 50, 100 ms), continuity continuous discontinuous), direction (e.g., forward backward). Using these 528 stimulus pairs were presented subjects who distinguish if in each pair the same or different. Then they rated using four scales measuring pleasantness,...

Three novel interaction methods were designed for reading six-dot Braille characters from the touchscreen of a mobile device. A prototype device with piezoelectric actuator embedded under was used to create tactile feedback. The three methods, scan, sweep, and rhythm, enabled users read one at time either by exploring dot or sensing rhythmic pattern presented on screen. tested five blind readers as proof concept. results first experiment showed that all can be convey information participants...

This paper investigated in two experiments pupillary responses to emotionally provocative sound stimuli. In experiment one, 30 subjects' were measured while listening 10 negatively and positively arousing sounds, neutral sounds. addition, the subjects rated their subjective experiences these The results showed that pupil size was significantly larger after highly positive negative stimuli than with medium arousal.

The present aim was to study a new technique for human--computer interaction. It combined the use of two modalities, voluntary gaze direction and facial muscle activation object pointing selection. Fourteen subjects performed series tasks with mouse. At short distances mouse significantly faster than technique. However, there were no statistically significant differences at medium long between techniques. Fitts' law analyses both by using only error-free trials also data including error...

We evaluated the effect of dog–owner relationship on dogs’ emotional reactivity, quantified with heart rate variability (HRV), behavioral changes, physical activity and dog owner interpretations. Twenty nine adult dogs encountered five different situations (i.e., stroking, a feeding toy, separation from owner, reunion sudden appearance novel object). The results showed that both negative positive provoked signs heightened arousal in dogs. During situations, owners’ ratings about correlated...

Feature-based method for detecting landmarks from facial images was designed. The based on extracting oriented edges and constructing edge maps at two resolution levels. Edge regions with characteristic pattern formed landmark candidates. ensured invariance to expressions while eyes. Nose mouth detection deteriorated by happiness disgust.

A light-weight, wearable, wireless gaze tracker with integrated selection command source for human-computer interaction is introduced. The prototype system combines head-mounted, video-based tracking capacitive facial movement detection that enable multimodal by pointing and making selections gestures. targeted mainly to disabled people limited mobility over their hands. hardware was made remove the need take off device when moving away from computer, allow future use in more mobile...

The present aim was to study if thermal stimuli presented the palm can affect emotional responses when measured with emotion related subjective rating scales and changes in skin conductance response (SCR). Two target temperatures, cold warm, were created by either decreasing or increasing temperature of stimulus 4 °C respect participants current hand temperature. Both warm using two presentation methods, i.e., dynamic pre-adjusted. results showed that both pre-adjusted elevated ratings...

We present a study comparing physiological and psychological restoration in matched real virtual natural environments. Participants (n=24) experienced forest, or one of two audiovisual forests wearing head-mounted display: A 3D forest 360-degree video. The results showed that some the benefits could also be obtained using equivalents. Furthermore, we found to emotionally more restorative than video forest. findings can used creating environments for people who are unable visit

Dog owners' understanding of the daily behaviour their dogs may be enhanced by movement measurements that can detect repeatable dog behaviour, such as levels activity and rest well changes. The aim this study was to evaluate performance supervised machine learning methods utilising accelerometer gyroscope data provided wearable sensors in classification seven typical activities a semi-controlled test situation. Forty-five middle large sized participated study. Two sensor devices were...

The present aim was to develop methods that estimate emotional experiences in real time from the electromyographic activity of two facial muscles: zygomaticus major (activated when smiling) and corrugator supercilii frowning). Ten subjects were stimulated with a series emotionally arousing pictures videos. After each stimulus rated valence their experience on nine-point bipolar dimensional scale. At same computer estimated subjects' ratings basis electrical during stimulation 70...

Illusory vibrotactile movement can be used to provide directional tactile information on the skin. Our research question was how presentation method affects perception of movement. Illusion mediolateral elicited a left dorsal forearm investigate cognitive and emotional experiences stimulation. Eighteen participants were presented with stimuli delivered linearly aligned row three actuators. Three methods used--saltation, amplitude modulation, hybrid method--to form 12 distinct patterns First,...

The sense of touch is a fundamental part social interaction as even short from another person can elicit emotional experiences. Previous studies on haptic communication indicate that the benefits interpersonal exist when artificially mediated between people are physically apart. In current study an evaluation three input gestures (i.e., moving, squeezing, and stroking) was conducted to identify preferred methods for creating messages using hand-held device. Furthermore, two output one or...
