Using physiological measures for emotional assessment: A computer-aided tool for cognitive and behavioural therapy

Abstract

In the context of Cognitive and Behavioural Therapies, the use of immersion technologies to replace classical exposure could improve the therapeutic process. As it is necessary to validate the efficiency of such a technique, both therapists and VR specialists need tools to monitor the impact of Virtual Reality Exposure on the patients. According to previous observations and experiments, it appears that an automatic evaluation of the Arousal and Valence components of affective reactions can provide significant information. The present study investigates a possible solution of Arousal and Valence computation from physiological measurements. Results show that the dimensional reduction is not statistically meaningful, but the correlations found encourage the investigation of this approach as a complement to cognitive and behavioural study of the patient.

Emotion Assessment: Arousal Evaluation Using EEG’s and Peripheral Physiological Signals

“…ElectroEncephalograms-EEG). In recent years interesting results have been obtained with the first category of signals ( [7], [8]). Very few studies however have used the second category [9], even though the cognitive theory states that the brain is heavily involved in emotions [2].…”

“…This strategy has been widely used for emotion assessment from facial expressions and to some extent from physiological signals [8]. However, even if actors are known to deeply feel the emotion they try to express, it is difficult to insure physiological responses that are consistent and reproducible by nonactors.…”

Emotion Recognition through Physiological Signals for Human-Machine Communication

“…This strategy has been widely used for emotion assessment from facial expressions and to some extent from physiological signals [13]. However, even if actors are known to deeply feel the emotion they try to express, it is difficult to insure physiological responses that are consistent and reproducible by nonactors.…”

Human factors consideration in the interaction process with virtual environment

“…All these different technologies contribute to the perception of this new virtual environment. Of course, cognitive factors play an important role in the perception process [14][15]. With these technologies, one important goal for industrials is to take a decision in a similar way in virtual environment than in real environment.…”
