From inflatable products to smart partners, the evolution of the life size sex doll can be called a technological miracle. In 2020, the joint ball-shaped endoskeleton was launched, allowing the flat chested sex doll to pose difficult yoga-level poses. The latest model is even equipped with pupil tracking and body temperature simulation, and automatically starts breathing when it detects the user’s approach. Development engineers revealed that the next generation of products will integrate brain-computer interface technology to achieve mind-controlled doll voice, completely blurring the boundaries between virtual and reality.
