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.
Claims37
A computer system comprising:
- one or more wireless interface devices, each wireless interface device being a pen-based system and including a digitizer responsive to pen events, said wireless interface devices also including means for enabling radio communication with a remote host and means for translating pen events into pen data packets and transmitting said pen data packets to a remote host for processing;
- and
- a host for communicating with said one or more wireless interface devices, said host including means for enabling communication with said one or more wireless interface devices by way of a radio link, said host also including means for receiving and processing said pen data packets.
A wireless interface device comprising:
- means for enabling radio communication with a remote host;
- a digitizer panel for receiving input data from a passive stylus;
- means for translating pen events relative to said digitizer panel to pen data defining a pen mode;
- and
- means for transmitting said pen data to a remote host for processing by way of a radio link during a pen mode;
- and
- means for providing local inking of said pen events.
