Abstract

An improved system and method for presenting computerized interactive forms (such as survey questionnaires, employment applications, etc.) via the Internet to human respondents making use of client computers. The invention is a cross-platform web application written in Java and JavaScript. The presented questions/items are selected dynamically as a respondent fills in the information for each question/item. A code-length-reducing software architecture—wherein all objects are widgets—along with a design choice of inheritance makes for maximum code clarity, impressive code compactness, and swift parsing. More information and a higher quality of information are collected from a respondent, because waiting time is reduced and only relevant questions are presented. Implementation of parent-child containment in the widget set, coupled with a JavaScript skeleton design system, facilitates respondent-friendly display design by interface designers, and a rapid design process.

Claims

1. A computer-implemented method for presenting survey questionnaires and other interactive forms, comprising:

a plurality of survey/interactive-form questions/items and at least one dependent question/item;

presenting at least one of the survey/interactive-form questions/items to a respondent;

receiving response data from the respondent; and

instantly presenting at least one of the dependent questions/items to the respondent.

2. The method of claim 1, wherein the survey/interactive form questions/items comprise initial questions/items and dependent questions/items.

3. The method of claim 2, wherein the initial questions are presented all-at-once to the respondent, and the method further comprises presenting at least one of the dependent questions to the respondent instantly, if the respondent chooses the initial question.

4. The method of claim 1, wherein the method is performed in a distributed computer system, comprising a webserver computer which includes a database, and wherein the interactive form (such as a survey questionnaire) is received via a browser at a client computer, and the method further comprises transmitting the survey/interactive form questions/items from the webserver computer to the client computer via the Internet.

5. The method of claim 4, further comprising storing the response data in the database.

6. The method of claim 5, further comprising storing interactive-form data from additional respondents in said database.

7. A software architecture system comprising:

a) A Controller object, implemented in JavaScript, for controlling the behavior displayed by the interactive form (such as a survey questionnaire) as it runs on the browser, and also optionally for communicating with the webserver computer via messages that it may send and receive.

b) A static data structure, implemented in JavaScript object literal notation as the Skeleton object, for controlling what appearance and content the interactive form (such as a survey questionnaire) displays on the browser, and defining what data validation routines are to be applied to respondent-supplied information.

c) A Model object for handling execution of the data validation routines.

d) A collection of widget objects for managing elements defined by hypertext markup language (HTML) and/or the Document Object Model (DOM).

8. The method of claim 7, further comprising:

a) The widget objects displaying at least one of visible, audible, tactile, and/or olfactory content on the browser to the respondent.

b) The widget objects receiving input from the respondent and updating at least one of what the respondent sees and/or hears, and perhaps also in the future feels and/or smells.

c) The widget objects notifying the controller of any input from the respondent.

9. The method of claim 7, further comprising the widget objects sensing the response data from the respondent and alerting the Controller object for review, and the Controller object checking with the Model object to perform any required validations of the response data from the respondent, before the Controller object sends the response information back to the webserver computer.

10. The method of claim 7, wherein all objects that directly affect the content and appearance of the screen are widgets—

technically, objects of type Widget.

11. The method of claim 7, wherein the Controller object

a) Creates a plurality of widget objects.

b) Directs at least one of the widget objects to draw itself.

12. The method of claim 11, wherein the widget object contains a reference to a parent widget, if any and a reference to a child widget, if any, and the method further optionally comprises a plurality of widgets including none or more child widgets, whereby the references to the parent widget and the child widgets thus maintain a tree structure of widgets.

13. The method of claim 11, wherein the widget that draws itself also commands those of its child widgets that are currently switched to be able to draw themselves to also draw themselves, and so on down a hierarchy, until child widgets are reached that have no children.

14. The method of claim 13 wherein the inclusion of references contained in a given widget and referring from the given widget to optional child widgets and an optional parent widget provides for a graphical respondent interface definition, whereby the need for a separate data structure outside of the widget objects themselves to keep track of and describe the widget hierarchy is obviated, and whereby extreme compactness and clarity of code is reached. The compactness and clarity of the code result in an improved experience for the respondent by virtue of reduced waiting time, and in increased usability for software developers using the system of claim 7. It remains possible for the Controller object to modify the widgets at will, regardless of the configuration defined at download time by the Skeleton object;

thus, customized coding may still be used to implement specific different behavior.

15. The method of claim 13, wherein all widgets are equipped with a ‘

getHTML’

method and a ‘

getChildrensHTML’

method by virtue of the fact that they all inherit from a single widget class that defines the minimum functionality for said methods, and wherein each ‘

getHTML’

method of a given widget is programmed to invoke a ‘

getChildrensHTML’

method of the given widget which in turn invokes the ‘

getHTML’

method of each child widget of the given widget, whereupon each ‘

getHTML’

method of each child widget invokes the ‘

getChildrensHTML’

method of each child widget, and so on forming what is recognized to those skilled in the art as a recursive control structure.

16. The method of claim 15, wherein the recursive control structure operates primarily with only two methods, the ‘

getHTML’

method and the ‘

getChildrensHTML’

method, and is directed entirely and inherently by the very same references that define the parent-child widget hierarchy, whereby considerable code is saved via the recursive control structure over a comparable iterative approach, and whereby the amount of excess code avoided results in less waiting time for the end respondent, giving an improved respondent experience and thus an improved application performance.

17. The method of claim 7, wherein the static data structure of the Skeleton object allows widgets to be placed anywhere and inside one another within an interactive form (such as a survey questionnaire), whereby all concomitant logic and/or programming work is taken care of automatically.

18. The method of claim 7, wherein the widgets are implemented via a set-architecture means for saving code size, decreasing parse time, and increasing clarity of purpose.

19. The method of claim 7, wherein a main constructor and a superconstructor are provided in order to simulate class-based inheritance in JavaScript.
