Abstract: The system and method for providing social context to digital activity combines mobile device contact information with user-provided website information to aid users when browsing the Internet. Users of mobile devices define identifications of themselves for websites, so that when another user in their contact list is browsing the Internet, an indicator is able to indicate that he is a known contact. The determination of whether the person is a known contact based on the identification definitions is able to be implemented either by direct interfacing between the host website and a server which stores the identification definitions, a browser plugin which communicates with the server or an API provided by the server or a mobile device.

Abstract: Embodiments of the present invention provide a computer implemented method and apparatus for processing user defined input on a graphical user interface (GUI). Initially, a first user defined input value is received in a first graphical processing element. This first graphical processing element determines if the first user defined input value is a valid input value. Typically, this is done by comparing the first user defined input value with a set of valid input values. The first graphical processing element and said feedback message are embedded in a second graphical processing element. The second graphical processing element receives a feedback message from the first graphical processing element if the first graphical processing element determines that the first user defined input value is invalid. The second graphical processing element displays the feedback message and the first graphical processing element in a GUI when the first user defined input value is invalid.
