In recent years, metaverse and digital humans have become important research and industry areas of focus. However, existing digital humans still lack realistic affective traits, making emotional interaction with humans difficult. Grounded in the developments of artificial intelligence, human-computer interaction, virtual reality, and affective computing, this paper proposes the concept and technical framework of "Affective Digital Twins for Digital Human" based on the philosophy of digital twin technology. The paper discusses several key technical issues including affective modeling, affective perception, affective encoding, and affective expression. Based on this, the paper conducts a preliminary imagination of the future application prospects of affective digital twins for digital human, while considering potential problems that may need to be addressed.
