The latest generation of torso sex dolls is breaking through the limitations of physical form and developing rapidly towards intelligence. By implanting micro sensors and voice modules, users can have basic emotional interactions with sex doll heads. Although existing technology cannot achieve deep conversations, simple emotional feedback systems have significantly improved the user experience. The prototype of a certain technology company even tried to integrate brainwave recognition technology, so that the product can automatically adjust the interaction mode according to the user's emotions. This cutting-edge exploration of combining biometrics with artificial intelligence may indicate that the relationship between man and machine is about to enter a new era.
