Abstract

A data input technique for a computer that provides the user with a historical list of potential choices for the data input is described. A historical list is displayed to the user so that the user can input data by selecting an item from the historical list being displayed. The historical list contains the most recently and/or frequently used data values for the data field that the user is inputting data. Preferably, the historical list is displayed over a form also being displayed that requires the data input into its one or more of its fields. By using the historical lists a user is able to enter data with a greater ease of use than previously obtainable. The historical can also be shared between different applications that execute on the computer system concurrently or at different times. By sharing the data between applications, the historical list becomes more useful and valuable to the user and thereby further improves the ease of use of the computer system. The data input technique can be implemented numerous ways, including as a system, an apparatus, a graphical user interface, or a method, or as a computer readable medium.

an I/O display system including at least an input tablet and a display screen;

a memory system for storing program code and data;

a CPU for processing the program code in accordance with the data; and

a plurality of history tables maintained within said memory system, each of said history tables corresponding to a different field class,

wherein when inputting data via the input tablet into a field of a form being displayed on said display screen, a list of choices is produced from said history table for the field class corresponding to the field and displayed on said display screen.

2. A pen-based computer system as recited in claim 1, wherein each of said history tables stores historical information concerning usage of data values with respect a different one of the field classes.

3. A pen-based computer system as recited in claim 2, wherein the list of choices produced from said history table is a menu list of most recently and frequently used data values for the field class.

4. A pen-based computer system as recited in claim 2, wherein when a user selects one of the choices from the list of choices, the selected choice is input into said computer system and displayed in said display screen in the field of the form.

5. A pen-based computer system as recited in claim 2, wherein said history table for the field class corresponding to the field is updated in accordance with a selected item.

6. A pen-based computer system as recited in claim 5, wherein said history tables comprise a plurality of entries, each entry including at least a data value, a time of last use, and a frequency of use.

7. A pen-based computer system as recited in claim 5, wherein the updating of said history tables causes at least one of (i) a data value to be placed in said history table and (ii) causes the time of last use and the frequency of use of one of the data values associated with the selected item to be updated.

8. A graphical user interface, comprising:

a history list for each of a plurality of field classes;

a form having at least one field requiring data input, the field being associated with one of the field classes; and

a history list selector for selecting the history list for the field based on the field class associated with the field.

9. A graphical user interface as recited in claim 8, wherein said history list for each of the field classes is a menu list of most recently and frequently used data values for the field classes.

10. A graphical user interface as recited in claim 9, wherein said graphical user interface is for a pen-based computer system, and

wherein said history list produced for each of the field classes stores historical information concerning usage of data values with respect the associated field class.

11. A method for inputting data into a computer system having a display screen associated therewith, said method comprising:

(a) displaying a form on the display screen of the computer system, the form having at least one field associated with a field class and requiring data entry by a user;

(b) displaying a history list associated with the field class on the display screen on the computer system;

(c) determining whether the user has selected an item from the displayed history list;

(d) assigning a data value for the field to that of a data value associated with the selected item when said determining (c) determines that the user has selected an item; and

(e) updating the history list in accordance with the selected item when said determining (c) determines that the user has selected an item.

12. A method as recited in claim 11, wherein the computer system is a pointer-based computer system.

13. A method as recited in claim 11, wherein the computer system is a pen-based computer system.

14. A method as recited in claim 11, wherein the history list is a list of most recently used data values for the field class.

15. A method as recited in claim 11,

wherein said method further comprises (f) inputting the data by some other means when said determining (c) determines that the user has not selected an item, and

wherein said updating (e) comprises:

(e1) determining whether the data value already exists in the history list; and

(e2) adding the data value to the history list if the data value is determined not to exist in the history list.

16. A method for inputting data into a computer system having a display screen associated therewith, said method comprising:

(a) providing a history table for each of a plurality of field classes;

(b) displaying a form on the display screen of the computer system, the form having at least one field requiring data entry by a user;

(c) producing a history list for the field on the display screen of the computer system based on the history table for the field class associated with the field;

(d) displaying the history list produced on the display screen of the computer system;

(e) determining whether the user has selected an item from the displayed history list;

(f) assigning a data value for the field to that of a data value associated with the selected item from the displayed history list when said determining (e) determines that the user has selected an item from the displayed history list; and

(g) updating the history table in accordance with the selected item when said determining (e) determines that the user has selected an item from the displayed history list.

17. A method as recited in claim 16, wherein the history table corresponding to each of the field classes includes a plurality of entries, each entry comprises a data value and usage information, and

wherein said producing (c) comprises:

(c1) identifying the history table for the field class associated with the field; and

(c2) generating the items of the history list from the data values in the history table identified.

18. A method as recited in claim 17, wherein said generating (c2) generates the items for the history list from the data values in the history table identified, and thereafter orders the items based on the usage information associated with the data values.

19. A method as recited in claim 18, wherein the usage information comprises a time of last use and a frequency of use for each data value in the history table.

20. A method as recited in claim 17, wherein the data values within the history table correspond directly or indirectly to input values for the field.

21. A method as recited in claim 17, wherein the data values comprise one of a data string and a data pointer, and wherein the data pointer points a data record containing pertinent information.
