Method of indirect specification of user preferences

Abstract

A system and method for allowing communication of a large number of parameters from a computer user to an application program with a relatively small amount of interaction. The system uses a plurality of graphical metaphors to represent a collection of known personality or collective knowledge representations to extract a computer user's preferences. A computer user expresses how much likeness exists between themselves and a set of metaphoric graphical objects which is translated into an intermediary format which enables the computer to provide a higher quality of pattern matching and differentiation.

Description

BACKGROUND OF THE INVENTION

1. Field of Invention

The present invention is generally directed to user interfaces which obtain information about a computer user. More specifically, the invention relates to a method of interactively obtaining user preferences based on selection of graphical objects.

2. Related Materials and Definitions

This application is related to the following co-pending applications which are hereby incorporated by reference:

FACILITY FOR THE INTELLIGENT SELECTION OF INFORMATION OBJECTS (PERSONA)-(application Ser. No. 08/262,834) is now allowed METHOD FOR GENERATING CONNECTIONS BETWEEN OBJECTS IN A COMPUTER NETWORK (Grinding) (application Ser. No. 08/262,999) now U.S. Pat. No. 5,608,900, METHOD FOR THE ASSOCIATION OF HETEROGENEOUS INFORMATION (application Ser. No. 08/262,838) is now allowed, FACILITY FOR THE STORAGE AND MANAGEMENT OF CONNECTIONS (CONNECTION SERVER) (application Ser. No. 08/267,022) is now application Ser. No. 08/741,291, now U.S. Pat. No. 5,687,367,

Computer applications often require a series of parameters to determine what action to take. It is frequently the responsibility of the computer user to specify many of these parameters in order to complete the proper sequencing and ultimately the completion of any interaction with the application. An application requiring a level of 100-200 parameters would far exceed the normal capability of the average computer user. In addition to the sheer amount of time necessary to comply with parameter requests, a user may make mistakes, not have a proper perspective of what is being requested or loose interest in the process.

What is needed is an intermediate step that is easy for the user to interact with that can produce these parameters in a shorter time and with greater certainty of accuracy. In other areas of computer interaction it is often the case that a prior history or pattern can statistically predict future results. What is needed is a method of manipulating a user's prior history when specifying variables as knowledge to produce levels of parameterization. The specific application of the above method would be applied in an effort to extract a user's personality or typical preferences.

3. Discussion of Prior Art

A product from Microsoft.RTM., Microsoft Bob.TM., uses avatars which could be dogs, teddy bears , snails, etc. which are intentionally not photographically real (i.e. animated characters) and represent non threatening tour guides for a single level of interaction. The user can select a object that then operates in a tour guide mode, but does not have the ability to blend the characteristics of each symbol to obtain additional levels of information.

The problem with the prior art is there has been no effective method of metaphorically expressing user preferences which can cover the full gambit of personalities, emotions, or preferential choices. In addition, no effective method has been developed to interact with the enormous set of possible parameters in a short time period, accurate in content and able to keep the interest of the user throughout the process.

DETAILED DESCRIPTION

Pattern Matching/Differentiation

To illustrate a conceptual development of a set of intermediate metaphors, a basic discussion of set theory may be useful. As shown in FIG. 1, eight circles 101, 102, 103, 104, 105 106, 107 and 108 represent various people having known personality traits. Each of the circles may represent a distinct generalized personality (i.e. scientist, clown, jock, teacher, millionaire, etc.) which would be commonly recognized by an average or specifically targeted group of computer users. Taken individually each of the circles may contain a very large number of traits which make up each personality. It is the intersection of these circles where common traits may exist and the non-intersection of these circles where differentiation exists.

By asking a user to select how much they feel they are like or not like each of the eight personality traits a series of overlaps will be noted. These overlaps, according to union theory, expand the original eight regions of parameters to many regions that overlap and cancel. For example, in FIG. 1, many subregions exist which now represent the union of personalities (109, 110, 111, etc.) for a total of approximately 22 different subsets. The overlap and non-overlap of these intersections shows a reinforcement and differentiation of a particular aspect of each the characters personality.

A computer user looks at the cast of characters of eight and tries to decide who are they most like. They can then rank these personalities to obtain a blend of characters which can produce a a set of parameters which can be processed by the computer application.

By asking the computer user 100 to only evaluate eight characters, a large number of parameters 112 can be evaluated. This example, in a simplified form, illustrates how people through an indirect method can cover a spectrum of possibilities without having knowledge of every possible parameter.

The present invention must imply a common language without external specification of the language. It is important that the metaphoric language tap into a highly well understood method for describing information at a high level (i.e., recognizing personality types that can be recognized globally by other psychologists). The metaphor group could apply to other things--dog lovers, librarians, scientists. People with the same interests could all find the same information, not because they know each other, but because they have similar common experiences/interests.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

The preferred embodiments of the instant invention operate within the framework of the co-pending application PERSONA, which is hereby incorporated by reference, and provides one method of interaction within that context. Many different applications may equally operate within the PERSONA framework and therefore this invention should not be considered to limit applicability nor should the present invention be limited to operate only within the PERSONA framework.

PERSONA lets a person describe themself so that the computer can act as their agent. This invention wants to simplify the process to develop enough information by asking a limited amount of questions.

In the preferred embodiments, a cast of eight metaphoric characters are created which represent a broad spectrum of human experiences. The characters must have a broad spectrum of age, gender, race, intellect, etc., in an attempt to encompass the entire spectrum of possibilities. Each character's personality is made up of a number of preselected attributes which can be selected as desired but must conform to proven personality attribute make-ups to achieve optimum results.

The specific application is to enable a user to provide information about a connection (e.g. a dog icon may be connected to page about a veterinarian clinic). With respect to connections it is important to have relative attribute values of a connection represent: 1) who made the connection, 2) what are we pointing to and 3) what is the relationship (attributes).

A desirable way of associating attributes with connections is essential in enabling a computer user of a particular interest level or personality to be intelligently and quickly directed to particular documents/data of interest. Who would be interested, what is the personality of the person making the connection and who would be interested in seeing the particular connection are all questions that the are answered by the present invention as described hereafter.

FIG. 2, illustrates a first transform 206 which obtains a ranked list of possible attributes for Persona 208 and a second transform 205 which takes a character and turns it into a set of discrete attribute values to attach to a connection. The particular transform methods are discussed further hereafter in the discussion of FIG. 5.

In the preferred implementation approximately 21 available attributes were differentiation maximized out of a total of 72 attribute pairs. The numerical values of 72 attribute pairs and subset of 21 attribute pairs were selected using an iterative process using successive approximation to determine optimum values. The object is to maximize differentiation while minimizing the amount of information carried. Using different character sets would produce different maximized number ranges.

FIG. 3 illustrates the preferred implementation using the eight characters Freddy Funlover, Granny Joe, Lisa Lerner, Marty Mover, Ricki Rebel, Sam Seeker, Sara Scout and Willie Wizard. The user is asked to place a value in the box to the left of each character a value of how much like each character their own personality or preferences resemble. It is this process which initiates the persona transformation of element 206.

Appendix A, pages 1 and 2 collectively, provide for profile definitions of each of the above eight characters. Such definitions provide a level of training to familiarize a user with the characteristics of each of the above eight characters.

FIGS. 4a and 4b, collectively, illustrate the eight characters Freddy Funlover, Granny Joe, Lisa Lerner, Marty Mover, Ricki Rebel, Sam Seeker, Sara Scout and Willie Wizard used now to determine who may be interested in a particular connection that a computer user is making. The user is asked to place a value in the box to the left of each character of how much each character might be interested in the connection being made. The user can choose to make no selection, at which time the system would default to the user's persona as determined in FIG. 3. It is this process which initiates the transformation of element 205.

FIG. 5 further illustrates the transformation process of steps 205 and 206 of FIG. 2. A computer user is asked to input values 500 indicating likeness to the eight personality characters 501. The values are then normalized as a percentage of 100%.

Using these percentages and the list of 72 preselected attributes of each personality 502, a list of the relative values of each of the 72 attributes that can be attributed to the percentage chosen for each of the eight personalities is determined. FIGS. 6a and 6b, collectively, provide for a spreadsheet showing a selected character Willie and the 72 attributes preselected for that character as well as some examples of relative values of the attributes. The weighted average of each list is then used to compile the final list of 72 attributes 503 which is used for the persona.

The transformation for element 205 is performed in a like manner with that of 204 by adding the additional steps of ordering by preference(ranking) 504 the 72 attributes of 503. The top 21 are then selected in element 505 and represent the 21 attributes attached to a particular connection.

The object is an effective use of attributes such that when a user tweaks a parameter value of one of the 8 characters it will cause a meaningful difference to occur.

In an alternative embodiment, personas may be blended to reflect an additional level of relative values. In this embodiment, personas are given proportional weighting to comply with an ordering based on a selected importance of each persona. An example of this, would be where responses to a first persona are treated favorably over response to a second persona. This proportional weighting would produce a biased blend of personas.

CONCLUSION

A system and method has been shown in the above embodiments for the effective implementation of a metaphoric interface for extracting a large set of parameters from a smaller set of inputs. While various preferred embodiments have been shown and described, it will be understood that there is no intent to limit the invention by such disclosure, but rather, is intended to cover all modifications and alternate constructions falling within the spirit and scope of the invention as defined in the appended claims.

While the preferred embodiment uses people as metaphoric objects, the invention could use any intermediate group of metaphors which would easily recognized by the average user or a targeted group of users. In addition the particular cast of eight characters used in the preferred embodiment could be changed to reflect whatever personality traits are desired. Changing personality sets would inherently change the attribute pair outcomes and persona developed as a result of the transformations of FIG. 2. ##SPC1##
