EMOTIONS & ROBOTS

 Emotions in Robots :

                             Robots have sensors corresponding to senses of humans. Humans can sense their environment according to the natural senses they have. Robots can be equipped with a number of such senses to sense their environment. There is an extensive research going on for recognizing the human emotions on the basis of different parameters like voice, facial expression and body language. For recognizing emotions from voice, VRA Technology seeks to interpret the complete emotional structure evident in individually assessed conversations (excitement, pain, fear, cognitive activity and more).

                              The correlation among these various emotional stress characteristics enables to determine whether a statement was, amongst other things, truthful, deceptive, uncertain and inaccurate. The speech of person can provide a lot of information about his emotional state. This information is present in acoustic properties like fundamental frequency, pitch, loudness, speech-rate and frequency range. The emotions in a robot will help to have more life-like Human Computer Interaction (HCI).

                          An emotion of a robot provides information about many aspects of the current state. They can tell about the intentions of the robot, its internal and external state and it may reveal what the robot is "up to". Emotions provide feed-back in the interaction with the robot how the robot feels about its environment. They also show how robot is affected by the people around it, what kind of emotions it understands and how it is adapting to the ever changing world around him.
