The general reason why you invoke the help of a robot is that your robot will help you improve the quality of your life. You will accept the presence of the robot more easily if the robot responds to you in the way a human being would.
Humanlike robots: should they produce or perceive emotion?
Science Fiction movies often show us robots that display emotions. The implicit idea behind this is that robots become more human as they learn to display emotions better. We would like to claim that these movies have it backwards! They display the production of emotion, whereas the perception of emotion should have priority.
Emotion perception that's where it starts
Perception rather than production is the natural starting point. Human infants start out by learning to understand language before they start to produce language. Likewise, the infant acquires the largest part of its emotional repertoire in the interaction with other people, where again perception skills precede production skills.
Emotion production can be faked, but emotion perception cannot.
It is easy to understand why so many SF movies (with Her as a good exception!) show the production of emotion instead: emotion production can be faked, but emotion perception cannot. At GVC we start from the natural side, that of emotion perception, a more demanding but also more rewarding point of departure.
GVC: interaction between humans and machines
GVC applications add emotion perception to the interaction between humans (you) and machines (e.g. your phone). When the machine is able to understand emotion, the machine can be said to have emotion. Wouldnt you love to have a phone that understands how you feel and that takes your feelings into account when interacting with you? That guesses correctly whether you are being sarcastic or sincere, and that consoles you when it senses that you are feeling sad?
