Computer system supporting portable interactive graphics display tablet and communications systems
First Claim
1. A computer system coupleable to a wide area network directly or through a local area network, for providing computing services within a predetermined area, said computer system comprisinga) a host computer providing for the execution of a host program that provides a stream of graphics display commands and graphics display data objects that, when graphically rendered, represents an interactive graphical user interface, and that is responsive to user provided input data;
- b) a host wireless transceiver coupleable to said host computer, wherein a portion of said wireless transceiver is locatable within said predetermined area to enable the wireless exchange of said stream and said user provided input data; and
c) one or more interactive graphical display tablets operable within said predetermined area with respect to said host computer, each of said interactive graphical display tablets including;
i) a graphics display suitable for presenting said interactive graphical user interface;
ii) a data input device for collecting said user provided input data;
iii) a tablet wireless transceiver for exchanging said stream and said user provided input data; and
iv) a processor, coupled between said graphics display, said data input device, and said tablet wireless transceiver, providing for the execution of a control program implementing graphics display commands that provide for the rendering of graphics display data objects,wherein said host computer selectively provides modified graphics display commands and selectively omits providing graphics display data objects as said stream to said host wireless transceiver.

Abstract
A portable display tablet is operated in conjunction with a base computer system including a host processor for executing an application program with an operational function that generates graphics data and operates in response to input data. The computer system includes a wireless data transceiver coupled to the processor that is capable of communicating the graphics and input data between the computer and portable display tablet. The portable display tablet includes a graphics display panel for displaying the graphical data, a low power wireless data transceiver providing short range data communication of the graphics and input data between the base computer system and portable display tablet, and a controller, embedded within the portable display tablet and coupled to the low power wireless data transceiver, that executes a control program to process the graphics data to provide the graphical display data to the graphics display panel.

11. A computer system supporting one or more portable wireless interactive graphics displays operable within a predefined area, said computer system comprising:
-
a) a host computer system including a first processor that executes a communications program and an application program, and a wireless transceiver, coupled to said first processor, that transmits first data and receives second data; and b) a portable wireless interactive graphics display device that includes a second processor that executes a control program, a wireless transceiver that transmits second data and receives first data, an output display that graphically represents said first data, and an input device that provides said second data, said second processor being coupled between said wireless transceiver, said output display and said input device, wherein said host computer system, through execution of said communications program, provides encoded graphical data objects and data object tags within said first data to said portable graphics display device, said communications program establishing a relation between a predetermined encoded graphical data object and a predetermined data object tag, and wherein said portable graphics display device, through execution of said control program, utilizes said relation to select said predetermined encoded graphical data object following receipt of said predetermined data object tag. - View Dependent Claims (12, 13, 14, 15, 16)

17. A computer system comprising:
-
a) a host computer that executes an operating system and a predetermined application program, said operating system including a routine providing for the transfer of display commands and display data objects, as defined by execution of said predetermined application program and wherein said display commands reference corresponding display data objects, to a first wireless transceiver and for receipt of input data, from said first wireless transceiver, for transfer to said predetermined application program; and b) a portable graphics display device, including a second wireless transceiver, responsive to said display commands and said display data objects as received from said second wireless transceiver and that provides said input data to said second wireless transceiver, said host computer providing for the caching of selected said display data objects by said portable graphics display device for subsequent rendering and display upon reference by selected said display commands, and wherein said host computer selectively modifies said selected display commands to reference said selected display data objects and omitting the transfer of corresponding ones of said display data objects from transfer to said to said first wireless transceiver. - View Dependent Claims (18, 19, 20)
