Physiological data feedback for application in distance education

Proceedings of the 2001 workshop on Perceptive user interfaces, 2001
This paper describes initial experiments collecting physiological data from subjects performing computer tasks. A prototype realtime Emotion Mouse collected skin temperature, galvanic skin response (GSR), and heartbeat data. Possible applications to distance education, and a second-generation system are discussed.

The effect of visual feedback on physiological muscle tremor

Electroencephalography and Clinical Neurophysiology, 1974
Abstract It has been reported that the availability of a visual monitor of force exerted during a voluntary constant contraction determines the presence or absence of a peak in the physiological tremor spectrum at 8–10 c/sec. This, together with other changes in the spectrum induced by added delays in the visual monitor system, has been taken to ...

Force feedback teleoperation with physiological motion compensation

IFAC Proceedings Volumes, 2009
Abstract In medical and surgical robotized applications one of the most recurrent problems is the physiological motion of the patient. Specifically, respiratory motion can have a large amplitude and thus prevent accurate gestures. So, for a robot which interacts with a patient, it is obvious that being able to compensate physiological motion would be ...

Somatostatin in the physiologic feedback control of thyrotropin secretion

Life Sciences, 1976
Abstract The addition of an antiserum against Somatostatin (SRIF) to a culture of dispersed rat pituitary cells incubated in the presence of hypothalamic tissue enhances thyrotropin (TSH) secretion into the medium. This indicates that SRIF is normally secreted in amounts sufficient to affect TSH secretion and suggests that SRIF may be the agent ...

Emotional and physiological responses to false feedback.

Cortex; a journal devoted to the study of the nervous system and behavior, 2001
The relationship between autonomic-visceral arousal and emotional experience is unclear. The attribution or cognitive-arousal theory of emotional experience posits that emotional experience is dependent on both visceral-autonomic nervous system feedback and the cognitive interpretation of the stimulus that induced this visceral activation.

Intelligent Physiological Monitoring and Feedback System for Driver Safety

2011 Fifth International Conference on Genetic and Evolutionary Computing, 2011
In the course of driving, sudden disease outbreak often cause serious traffic accidents. If drivers can real-time understand their physiological state, and then they could have a chance to get the best solution at the first time. Maybe accidents will be largely reduced.

Unresponsiveness of the endorphinergic system to its physiological feedback in obesity

Appetite, 1991
Beta-endorphin (beta-Ep) plasma levels are higher in obese patients than in normal subjects. To establish that this finding constitutes hyperendorphinemia, 28 obese patients aged 12-55 years, six males and 22 females, (weighing 61-117 kg) were investigated twice by an overnight 1-mg p.o. dose dexamethasone suppression test (DST) before and after weight

Physiological Significance of the Negative Short-Loop Feedback of Prolactin

Neuroendocrinology, 2008
The aim of the present study was to evaluate the physiological significance of the rapid, short-loop, negative feedback of prolactin by passive immunization with antiserum to rat prolactin injected into the third cerebral ventricle (3 V) of conscious, freely moving intact or castrated male rats.

Feedback from Physiological Sensors in the Classroom

2015
The Bill and Melinda Gates Foundation recently announced the development of an “engagement pedometer” that can identify exciting or boring moments to be used in classrooms. Researchers at the University of Hawaii have also developed potential real-time cognitive load indicators that also could be used in the classroom.

The Impact of System Feedback on Learners’ Affective and Physiological States

2010
We investigate how positive, neutral and negative feedback responses from an Intelligent Tutoring System (ITS) influences learners' affect and physiology. AutoTutor, an ITS with conversational dialogues, was used by learners (n=16) while their physiological signals (heart signal, facial muscle signal and skin conductivity) were recorded.
