Emotional computing is the theory that computers can detect human emotions, and respond like humans, as it's given in the line "As a result, computers will soon detect our growing irritation at their behaviour and in turn generate more sympathetic, human-like messages or slow down the tempo of the games they are running." Emotional computing is about human emotions, hence we choose an option that means the same. 'Sensitive responses' is closest to emotional computing in meaning, as it's about human responses, "sympathetic, human-like messages" and needs to be sensitive to humans while conversing, hence option B is correct. 'Feeling hurt' does not mean the same as emotional computing, in fact it's the opposite, emotional computing is an innovation that could avoid humans feeling hurt, it's a negative feeling that needs to be avoided, and emotional computing could do that, hence option A is incorrect. 'Slowing down' refers to speed that is reduced, it does not refer to emotions, in fact it's one of the actions carried out by emotional computing, it could slow down the tempo of games to avoid rage by the human playing that game, hence option C is incorrect.. 'Artificial intelligence' is a theory that computers can perform tasks that require human intelligence, like speech recognition, decision making, translation. Intelligence is the cognitive part, whereas emotional computing deals with human emotions. Emotional computing stems from artificial intelligence, but it's a combination of "artificial intelligence, psychology, electronics and other research fields', hence it does not mean exactly the same and option D is incorrect.
