  • Ink trails on a wireless remote interface tablet and cross-reference to related cases
    Publication number: 20080055280
    Abstract: A computer system which includes one or more wireless interface devices that are adapted to communicate with a remote host over a radio link. Each of the wireless interface devices is a pen-based device which includes an ink field in which pen events are translated into pen data packets and transmitted to the remote host over the radio link. Local inking is provided at the wireless interface device in order to maintain the pen paradigm in essentially real time.
