Affective computing and HCI

Human body responds according to different circumstances and exhibits different physical changes. These changes comprises of facial expression, skin conductance, heartbeat, brain signals, body temperature, pulse rate, etc. Advancement in bio-medical technology gives us access to identify even a small change in physical parameter. For an example fear release excessive amount of sweat compare to normal condition,Happiness makes our body warm. Excitement and anticipation makes our heart rate faster. Significant changes in brain signals have been witnessed in EEG and FMRI study for different emotions. There are number of such physical changes reported in literature which bolster the era of Affective Computing. Since last one decade, this title has grabbed a wide attention from all area of science and technology around the globe. Emotion assessment was successfully done by different research community by means of different bio-medical tools like, electroencephalography (EEG), electrocardiogram (ECG), galvanic skin response (GSR), heart rate variability (HRV), etc. But still a lot more challenges are yet to encounter.
Stay tuned for more up comings :) :)
