Maybe they might be happy to chat with a chatbot or just have a conversation with an avatar on the computer. There are lots of open questions about that. People may act normally in their day-to-day life. It's a very big problem and not solved yet. The main aim is to help. Can we have some tools that can be helpful, that can make use of this kind of knowledge that I can encode in a model to be able to suggest interventions? It is still a hard problem. When we teach a child to draw a smile, we show a curved mouth, and it's enough. But we detect a smile much better from the eyes than from the shape of the mouth. So it's very complex, and you say that computer vision can do it simply. In my eyes, it's a very complex field. It is complex because, as you mentioned, now the model will also learn something other than just themouth, right? It will learn the whole face structure. It will also learn the context. Before, it was only looking at just some landmarks, movement, and very simple features. Now there are much more complex features, especially for the face.
