  • Systems and methods for delivery and use of interactive objects
    Patent number: 10791082
    Abstract: A server and a number of client devices are connected via a network. Interactive objects are initiated in one of the client devices and delivered to any number of other client devices over the network. Real-time interactions between the object sender and the object receiver(s) can then be engaged using event-triggering mechanisms built into the client devices and applied onto the objects, and be coordinated by a coordinating module in the server. The interactive objects may carry instructions for event-triggered loading, activating and execution of functional widgets, such as workflows or collaborations, stored in the same server or elsewhere on the network. Once loaded in a client device, a widget needs not to be reloaded upon further use. Furthermore, the coordinating module may be linked to a machine-learning module in the same server or elsewhere on the network.
