Abstract: Techniques for sharing or transferring content between connected devices via dynamic collaboration user interfaces. An embodiment involves creating a first collaboration user interface between a first device and a second device. Via the first collaboration user interface, selecting content to be made available to a third device, where the selected content is currently available to the first device and not currently available to the third device. A second collaboration user interface is created between the second device and the third device. State information may be provided to a user via at least one of the first collaboration user interface and the second collaboration user interface. The second collaboration user interface causes the selected content to be available to the third device. Other embodiments may be described and claimed.
