1. A mobile user interface device for controlling a host computer, comprising:
- a graphical display subsystem, including a graphical display, for displaying an image;
an input subsystem, including a stylus, for receiving from a user positional data representing spatial positions of said stylus; and
a wireless communication subsystem for sending data to and receiving data from said host computer over a wireless communication link; and
means for controlling operations of said graphical display subsystem, said input subsystem and said wireless communication subsystem, said means for controlling (i) causing said wireless communication link to be created;
(ii) causing an application program to be run on said host computer;
(iii) receiving from said input subsystem said positional data, providing a response to said user in acknowledgment of said positional data, and transmitting over said wireless communication link said positional data to said application program; and
(iv) receiving over said wireless communication link from said application program data representing said image, and causing said graphical display subsystem to display said image on said graphical display.

Abstract
A mobile interface device receiving input from a stylus is provided to remotely control application programs running on a host computer. Such an interface device provides convenient access to any resource of the host computer, including, for example, a sharable database. An embodiment of such an interface device includes a pen-based graphical interface which communicates with an operating system on the host computer. In that embodiment, the operating system on the host computer has handwriting recognition capability.
