The following describes several representative integrated R D collaboration platforms. These systems are commercial systems and the design ideas basically meet the above three conditions. Of course, as a representative of the next generation of collaboration platforms, most of these systems have been launched soon, and it is hard to say that they can be improved. There are still many gaps from the systems discussed above. However, as these systems continue to improve, I believe that some mature
