Abstract

A dynamically variable keyboard terminal system having a keyboard display unit using an input panel with a plurality of touch-sensitive locations thereon and a keyboard display unit in alignment therewith. The system includes means for generating and storing information concerning symbols which make up one or more working symbol sets, such symbol information being author definable in accordance with a predetermined terminal definition language. The symbol information can include a symbol configuration for display, if applicable, or a symbol action to be performed, if applicable. Means are also provided for generating and storing information concerning a plurality of keyboard images which use such symbols and which keyboard information can be used for displaying a keyboard image at the keyboard display unit. A user can selectively touch one or more such locations so as to obtain symbol information for display on the keyboard display unit or on a monitor display unit, if applicable, or for performing an action associated with such symbol, if applicable.

Claims

1. A dynamic keyboard terminal system comprising

a memory means for storing a data base comprising information concerning symbols and keyboard images, wherein said symbol information includes at least a symbol code for identifying said symbol and symbol description information describing said symbol, said description information including at least information defining a symbol configuration or information defining an action associated with said symbol and wherein said keyboard information includes at least a description of the keys involved in said keyboard image, each said key description including at least the location of the key, the appearance of the key, and the symbol code associated with the key;

input means comprising a panel means having a keyboard image and a plurality of touch-sensitive locations which can be activated by a user in a manner such that selected combinations of activated touch-sensitive locations corresponding to symbols available in said data base can provide information concerning the modification of previously available symbols and keyboard images or the creation of new symbols and keyboard images;

logic means, responsive to the information concerning said modified or new symbols and keyboard images, for storing said information in said data base;

means for displaying a selected one of said keyboard images in alignment with said panel means so tht one or more selected touch-sensitive locations are associated with each of the keys of the currently displayed keyboard image;

accessing means, responsive to the selective activation of a key by a user, for accessing stored information concerning a selected symbol associated with said activated key or received symbol code; and

further means, responsive to the accessed information, for displaying the configuration of said symbol and performing the associated action of said symbol.

2. A system in accordance with claim 1 and further including means capable of making symbol codes available to one or more facilities which are external to said keyboard terminal system.

3. A system in accordance with claim 1 wherein said accessing means is responsive to the consecutive touching of separate keys and to the simultaneous touching of a plurality of different keys.

4. A system in accordance with claim 3 wherein said accessing means comprises means for electronically scanning all of the touch sensitive locations of a currently displayed keyboard image and for providing a list of said touch sensitive locations which correspond to keys which have been selectively touched on said currently displayed keyboard image.

5. A system in accordance with claim 4 wherein one or more of the keys of a selected keyboard image can be associated with a plurality of different symbols, the particular ones of said symbols being selectively determined when said one or more keys of a currently displayed keyboard image is touched by a user in accordance with the touched status of one or more concurrently touched shift keys of said currently displayed keyboard image.

6. A system in accordance with claim 3 and further including means for displaying a sequence of selected symbols at a selected location on said display means to permit the editing of said sequence of selected symbols.

7. A system in accordance with claim 3 and further including means for activating only a preselected part of the configuration or associated action information of a symbol.

8. A system in accordance with claim 1 wherein said accessing means further includes means for identifying touched locations of a currently displayed keyboard image which are not defined as keys, said non-key locations being capable of use as arguments for actions to be performed in association with symbols corresponding to selected touch keys of a currently displayed keyboard image.

9. A system in accordance with claim 1 wherein the symbol code associated with a specified symbol is the same symbol code for all keys in the working keyboard image set which are associated with said symbol.

10. A system in accordance with claim 1 wherein said accessing means is capable of accepting and is responsive to a plurality of symbol codes which are transmitted thereto from sources external to said terminal system and which are contained in the stored working symbol set of said terminal system.

11. A system in accordance with claim 1 and further including means for dynamically altering the contents of a currently selected keyboard image which is being displayed at said keyboard display unit.

12. A system in accordance with claim 2 wherein the symbol information associated with the symbols of a working symbol set may include, if applicable, an alternative set of symbol codes associated with a specified symbol, said last-named means being capable of making available either the symbol code normally associated with said specified symbol or the alternative set of symbol codes associated therewith.
