The Evolution of Smart Pets: From 90s Electronic Pets to Today's Robotic Companions. Smart pets have gradually evolved from 2D to 3D environments, with realistic appearances and animations, offering richer interactive experiences. These pets interact with users through generative dialogue systems, providing personalized services and differentiated emotional experiences. The future of the smart pet market looks promising, with more varieties and functionalities. However, virtual pets lack vitality and liveliness. The advantage of smart pets, though, is their ability to continuously upgrade and iterate, without the issues of illness or death. The smart pet market holds immense potential, with an increasing number of people joining the "smart pet care" trend. The appearance, functions, and personalities of virtual pets can be customized according to user preferences. Future smart pets may closely resemble real pets in appearance and behavior, offering more authentic companionship and interactive experiences.
