Affective Computing: Unleashing the Power of Emotion

In online learning programs, one of the major challenges is to identify
whether students are able to understand the concept or no.

Teacher can’t keep ‘an eye’ on all the students or the screen of students.

On similar note, how about your car sensing, if you are drowsy or distracted
and contact your friends or emergency services.

Medical wearables sending alerts to the individual and his family members,
if there is big change in emotional state of that person.
