Portable interactive graphics display tablet and communications system

A portable graphics display tablet that provides wireless remote display of graphical data, said portable graphics display tablet comprising:

• a) a display panel having a graphical display resolution equal to or greater than about 320 by 240 pixels, said display panel providing for rasterization of graphics display data for presentation as graphical data by said display panel;
• b) a wireless transceiver configured to exchange predetermined data with a remote computer system within a predetermined range of said remote computer system, said predetermined data including low-level graphics calls, graphics bit-maps and tag data, sent from said remote computer system to said portable graphics display tablet, and user input data sent from said graphics display tablet to said remote computer system;
• c) an input device suitable for receiving user provided input data;
• d) a processor coupled to said display panel, said wireless transceiver, and said input device, said processor configured to provide conversion of low-level graphics calls and graphics bit-maps to graphics display data, and to digitize user input data, said processor including an object cache coupled to said processor to store instances of predetermined graphic data corresponding to said graphics display data, said instances being identifiable by said tag data, said processor being responsive to instances of said tag data received from said wireless transceiver to access a respective instances of said predetermined graphic data;
• and
• e) a display tablet case housing said display panel, said wireless transceiver, said input device, and said processor within said display tablet case permitting continuous portable use of said portable graphics display tablet within said predetermined range.

A portable graphics display tablet operable as a wireless graphical computer interface, said portable graphics display tablet comprising:

• a) a graphics display configured to provide presentation of first data;
• b) a transceiver that provides wireless communication of second data including graphical data objects transmitted to said portable graphics display tablet;
• c) a processor system coupled to said graphics display for providing said first data and coupled to said transceiver for exchanging said second data, said processor system including a control program that provides for operating on said second data to identify and execute display commands to provide said graphics display with said first data, said processor system further including an object store for storing said graphical data objects selectable by reference by display commands for producing said first data,
• wherein said second data provided to said processor system includes graphical data objects that are stored to said object store subject to reference identification;
• wherein a first predetermined display command includes a reference identification of a first predetermined graphical data object and a second predetermined display command includes a reference identification of a second graphical data object;
• and
• wherein said control program selects said first predetermined graphical data object in connection with execution of said first predetermined display command and selects said second graphical data object in connection with execution of said second predetermined display command, and
• d) a portable case enclosing said graphics display, said transceiver, and said processor system while permitting operation as said wireless graphical computer interface.

A portable graphics display tablet, comprising:

• a) graphics display panel for presentation of a predetermined graphics image;
• b) a pointer device for providing pointer input data;
• c) a keyed input device for providing key input data;
• and
• d) a controller provided within a common housing with said graphics display panel, said pointer device, and said keyed input device;
• wherein:
• said controller including a transceiver subsystem permitting reception of graphic drawing commands and compressed graphics data objects transmitted to said portable graphics display tablet, and transmission of pointer input data and key input data from said portable graphics display tablet;
• and
• said controller supporting reception of tagged compressed graphics data objects, and configured to provide decompression of a predetermined tagged compressed graphics data object, received by said portable graphics display tablet prior to receipt of a predetermined graphics drawing command associated with a predetermined graphics object tag that uniquely corresponds to said tagged compressed graphics data object, in connection with the receipt and execution of said predetermined graphics drawing command by said controller in connection with providing said graphics display panel with said predetermined graphics image.
