Augmenting online interpersonal communication with biosignals, often in the form of heart rate sharing, has shown promise in increasing affiliation, feelings of closeness, and intimacy. Increasing empathetic awareness in the professional domain and in the customer interface could benefit both customer and employee satisfaction, but heart rate sharing in this context needs to consider issues around physiological monitoring of employees, appropriate level of intimacy, as well as the productivity outlook. In this study, we explore heart rate sharing at the workplace and study its effects on task performance. Altogether, 124 participants completed a collaborative visual guidance task using a chat box with heart rate visualization. Participants’ feedback about heart rate sharing reveal themes such as a stronger sense of human contact and increased self-reflection, but also raise concerns around unnecessity, intimacy, privacy and negative interpretations. Live heart rate was always measured, but to investigate the effect of heart rate sharing on task performance, half of the customers were told that they were seeing a recording, and half were told that they were seeing the advisor’s live heart beat. We found a negative link between awareness and task performance. We also found that higher ratings of usefulness of the heart rate visualization were associated with increased feelings of closeness. These results reveal that intimacy and privacy issues are particularly important for heart rate sharing in professional contexts, that preference modulates the effects of heart rate sharing on social closeness, and that heart rate sharing may have a negative effect on performance.

The purpose of the study was to identify significant changes in heart rate variability (an emerging descriptor of emotional conditions; HRV) concomitant to complex auditory stimuli with emotional value (music). In healthy controls, traumatic brain injured (TBI) patients, and subjects in the vegetative state (VS) the heart beat was continuously recorded while the subjects were passively listening to each of four music samples of different authorship. The heart rate (parametric and nonparametric) frequency spectra were computed and the spectra descriptors were processed by data-mining procedures. Data-mining sorted the nu_lf (normalized parameter unit of the spectrum low frequency range) as the significant descriptor by which the healthy controls, TBI patients, and VS subjects’ HRV responses to music could be clustered in classes matching those defined by the controls and TBI patients’ subjective reports. These findings promote the potential for HRV to reflect complex emotional stimuli and suggest that residual emotional reactions continue to occur in VS. HRV descriptors and data-mining appear applicable in brain function research in the absence of consciousness.

We examined how taboo conversation topics, such as being arrested, religion, and one's body weight, affect impression formation and task performance. In an experiment with 109 women, each participant and a female research confederate, whom the participant believed to be another participant, had a conversation and were asked to complete a task. We manipulated the conversation topics and actual task performance of the confederate, and measured participants' communication satisfaction; perception of the confederate's social, physical, and task attractiveness; and task performance. The results show that when the confederate performed well and appropriate (vs. taboo) conversation topics were discussed, the participants formed a more positive impression of the confederate and evaluated her task performance more positively. Therefore, if social norms for appropriate conversation topics are not followed, individuals may be less satisfied with their interpersonal communication interaction with the person who has not observed the norms, and may evaluate the task performance of that other person more negatively.

Non-contact pulse detector used for heart beat measurement based on computer vision, where a standard color camera captures the plethysmographic signal and the heart rates are processed and estimated dynamically. It is important that the quantities are taken in a non-invasive manner, which is invisible to the patient. Presently, many methods have been proposed for non-contact measurement. The proposed method based on the computer vision technique is enhanced to overcome the above drawbacks and it requires low computational cost. Many of the hospitals are using surveillance cameras, from these cameras we can monitor the video of the patients waiting in the queue. The camera is attached in the patients’ waiting room and the faces of the patients are monitored. Many factors are considered in the phases of image acquisition, as well as in the plethysmographic signal development, pre-processing and filtering. The pre-filter step uses numerical analysis techniques to cut the signal offset. The proposed method decouples the heart rate from the plethysmographic signal frequency. The proposed system helps in detecting the heart rate of a Patient who is waiting in queue for longer time. Based on the heart rate the seriousness of patient is identified and giving the preference to the patient and treatment will be started, with this the patient will be in safe side.

Excessive Stress

Air transport development brings an increased focus on the safety of piloting. The safety conditions can be assessed by mental workload. Psychic discomfort or excessive stress on pilots can negatively influence the course of flights. Therefore it appears convenient to monitor such parameters, which represent the mental wellbeing, or discomfort of a pilot. Since physiological measurements can provide a good information about mental workload or stress, this work primarily focuses on the observation of the change in heart rate, as it is an indicator of stress during the training of pilots, using the designed modular telemetry system. Another aim of this study is to evaluate the influence of a change in the avionic data visualization. This can have an unfavorable effect on the piloting of an airplane. This work, based on the evaluation of heart rate shows, that the switch from analog visualization to glass cockpit creates increased levels of stress in pilots, which was proved for all examined subjects except one. Significant level of correlation in the heart beat rate change in subjects in the course of training was also discovered.

Background: Caffeine consumption may adversely affect the performance of athletes in some sports. Aim: The aim of this study was to investigate the effects of caffeine drink consumed before competitions by air pistol athletes on their heart rate, trigger squeeze times and shooting scores. Methods: : In the study, caffeinated and caffeine-free measurements were applied on the same athletes. Following the evaluation, a total of 20 elite athletes, including 10 women with a mean age of 23.6±4.7 and 10 men with a mean age of 25.9±4.8 who had at least 2 years sports history, participated voluntarily in the study. The study was planned as a single blind. All athletes shot 10 times before both measurements. By random method, the athletes consumed Coffee with 3mg/kg caffeine or decaf coffee before the measurement. After 1 week, the same athletes were given coffee which was not given in the previous measurement before the measurement. A total of 80 shots were fired at 15, 30 and 60 minutes after both measurements. Following the evaluation, heart rates, trigger squeeze times and shooting scores of the athletes were recorded. Wilcoxon test to compare the differences between the measurements at two different times on the same group and Mann-Whitney U test to examine the differences in independent groups were used. Results: When the differences between the measurements of all male and female athletes were examined, it was found that there was an increase in their heart rate and trigger squeeze times 15, 30 and 60 minutes after caffeinated coffee consumption, and this difference was statistically significant (p<0.05). Besides there was a significant decrease in 15, 30 and 60 minute shooting scores of female athletes, and 15 and 30 minute shooting scores of male athletes (p<0.05). Conclusion: As a result of the study, it was observed that the use of caffeine had a negative effect on the performance of air pistol athletes. Therefore, it can be said that people interested in air pistol discipline should not consume coffee or caffeine-containing beverages within 1-2 hours before the competition, if they consume, their heart rate will increase and their aiming during shooting will be more difficult and trigger-squeezing times will be extended.

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Population aging is a common phenomenon in a society. The developed country like the United States, eldercare is becoming an important issue nowadays. There are many aspects we need to address for eldercare, including - circulatory system, alimentary system, nervous system and so on. In this research study, we focus on the heart rate monitoring and estimation using a hydraulic bed sensor. In addition, we also develop the fall detection technique using a Doppler radar. The hydraulic bed sensor for heart rate monitoring is placed under the mattress. The sensor system contains four tubes filled with water and uses the pressure sensor to obtain the Ballistocardiogram (BCG) signal. The BCG signal contains the information of heart beat, respiratory rate and body motion. Two algorithms are developed to process the bed sensor data. One uses the Hilbert transform and the other is based on the energy. By using the algorithms we developed, we can extract the heart beat information to estimate the heart rate. The system has been validated in a well controlled lab environment and a nursing house. In addition to the heart rate, the relative blood pressure measurement by using two features extracted from the bed sensor signal has also been developed and validated with 48 people data. The results show high correlation coefficient with the groundtruth. The Doppler radar for human fall detection is mounted in the ceiling. The radar senses the motion of an object and produces outputs based on the Doppler shift effect. We propose an effective method based on Wavelet Transform (WT) for fall vs. nonfall classification. The proposed fall detection classi er can distinguish between the fall and daily activities. The good performance of the proposed detection method has been validated through the data from the lab and in-home environments, with the falls from stunt actors and senior residents. To further improve the performance, we introduce an additional radar mounted on the wall. Based on the same detection method as when using one radar, we extract and concatenate the features from two radars for classification. The result shows outstanding improvement.

Conversations about palliative care pose multiple challenges for patients, families, and clinicians. This chapter emphasizes the critical role of relationships in communication, highlights common practical challenges that arise in communication about palliative care issues, and proposes specific strategies for addressing them. Examples of language that expresses key clinician interventions is included. Patient-related communication challenges include dealing with anxiety, denial, anger, and grief and sadness. Approaches to family communication challenges focus on the desire to protect the patient, unexpressed grief, and unrealistic expectations, while those related to the clinician include attachment and grief, and discussing prognosis. The role of patient and family preparation, fostered through early, direct, and gentle conversations, is emphasized as a key practice that supports coping and adaptation. Clinicians are conceptualized as supporting patients through attention to the patient and family as persons, the use of skilful interpersonal communication, authenticity, and a commitment to ongoing self-reflection and flexibility.

Due to increasing safety standards in air transport, the emphasis is put on human factors in this domain. This<br />regards especially the improvement of piloting precision during flight training and the elimination of internal and<br />external influences with negative effect on pilots. This paper is focused on evaluation of pilot’s psychophysiological<br />state during flight training on a simulator and in an aircraft and also on pilot’s reaction on transfer from analogue<br />to digital visual presentation of avionic data. The best indicator for evaluating human’s psychophysiological<br />condition could be a heart rate because of its descriptive activity of human heart and its psychophysiological<br />character based on sympathovagal balance of autonomic nervous system. In this paper heart rate frequency<br />is measured by FlexiGuard biotelemetry mobile device and by a Garmin c<br /> chest belt. This paper is oriented<br />towards description and comparison of the most common methods for physiological parameters assessment, i.e.<br />time and frequency domain analysis and non-parametric methods analysis. The paper also describes a wavelet<br />transform. The results show that not every parameter resulting from each analysis could be a good indicator<br />describing pilot’s stress. Results also show which parameters might work as good indicators of pilot’s stress<br />– those are LF/HF ratio and parameters measured by wavelet transform. Best way to define pilot’s stress on<br />simulators in real time indicates to be wavelet.

We investigated the periodic characteristics of bursting discharge in renal sympathetic nerve activity (RSNA) in conscious rats. Employing a discrete fast Fourier transform algorithm, a power spectrum analysis was used to quantify periodicities present in rectified and integrated RSNA whose signal-to-noise ratio in the recordings was greater than six. In conscious rats with intact baroreceptors, RSNA was characterized by four frequency components occurring at about 0.5, 1.5, 6, and 12 Hz, which corresponded to the low-frequency fluctuation of heart rate, respiration, and frequency of heart beat, and its harmonics, respectively. After intravenous infusion of sodium nitroprusside (SNP) to elicit reflex increases in RSNA and heart rate, the power for the component at 6 Hz followed the changes in heart beat frequency and was significantly increased, while those for the three other components were attenuated or experienced no change. In sino-aortic denervated (SAD) conscious rats, all four components were abolished, and the power spectrum was well fitted by a flat or Lorentzian curve, suggesting an almost random pattern. Only a respiratory-related component, which suggested common central modulation, appeared sporadically for short periods but was absent for the most part. Therefore most of this component together with the low-frequency component was also likely due to the baroreceptor-dependent peripheral modulation. The activity was sorted in 15 subgroups on the basis of spike amplitudes in the RSNA. Each subgroup showed frequency characteristics similar to the whole nerve activity. These results suggest that all periodicity in the RSNA of conscious rats with intact baroreceptors is caused by the baroreceptor input.
