???first is there a software on the computer where through the webcam it can recognise your face and then say hello/ hi how are you today? that would be a real help.
also if i make this robot which incorporates my computer to work it. is there a software which would recognise hand gestures and gestures. such as pointing in a direction and the robot goes there and waving it waves back. also going even more advanced be able to detect a sad face/crying
and say why are you sad.
thanks in advance (hopefully)
