The LetsGoDigital resource spoke about several Samsung patents that describe the output of images from smartphones to an additional holographic screen. The system can be a docking station with a display on which the picture is projected. If there are additional sensors, it will be possible to register interactive interaction with an external screen.
On the accompanying diagrams, journalists describe possible algorithms for interacting with the interface.
Note that the presence of a patent for a particular technology does not mean that it will soon appear in real products.
