The docking device provides file-sharing and cut-and-paste functions across the different docked host computers. Laptops, tabletops as well as Smartphones, tablets and other forms of portable platforms are supported. Dragging an item from a display designated to a first host computer to a display designated to a second host computer performs moving or copying the item from the first host to the second host.

Abstract: A system enabling a computer user to securely share a single set of keyboard and mouse (KM) among multiple isolated computers. The system enables one set of peripheral devices to independently interact with multiple coupled isolated computers through mouse position analysis on a virtual display area corresponding to multiple physical user displays of the particular installation. The system may be used to enable computer user having multiple isolated computers each with one or more coupled display to automatically switch a single set of keyboard mouse and other peripheral devices between the different computers. As isolated computers may have different security levels, the method and apparatus of the present invention prevents and potential data leakages between computers and coupled networks.
