One example is the flip phone. It was inspired by the communicators in 'Star Trek'. Another is the self - driving cars, which have some similarities to the automated vehicles often seen in science fiction stories. And then there are tablets. The idea of a flat, portable computing device like a tablet was seen in science fiction long before the iPad and other tablets became a reality.
Well, there are quite a few. For instance, smart glasses. Science fiction has often depicted characters wearing glasses with advanced functions, and now we have smart glasses like Google Glass (though it had some challenges). The concept of virtual reality also has its roots in science fiction. Writers and filmmakers have shown virtual worlds for decades, and today we have VR headsets that allow us to experience immersive virtual environments. And don't forget about the concept of wireless power transfer, which has been in science fiction and is now being developed in the real world.
