The invention relates to a computer-implemented network node and a method for associating different input devices, for example, when different user inputs of a
virtual conference occur at the same time and / or in a prototype
design phase of a new product, in particular an internet-based product, the user inputs of the
virtual conference occur at the same time and / or in the prototype
design phase of the new product, in particular
the internet-based product. It is used by testing and / or resolving tasks by means of shared data files and / or shared virtual workareas. According to the invention, it is possible for the first time; different participants, different devices within a virtual project space may collaborate without interference in the sense of "no compatibility problem", i.e. Simultaneously and without loss due to data collisions via one network node, independently of the capabilities, languages, operating systems of, for example, input devices and / or output devices.
