Solution Overview

Problem

Existing virtual agents provide monotonous and uninteresting interactions, leading to user frustration and premature termination of sessions, resulting in reduced user engagement and retention.

Innovation Solution

A system that personalizes virtual agent interactions using AI and IoT devices, integrating audio and visual components based on user preferences and real-time data, applying a ranking algorithm to select the most appealing persona and guide users through workflows, adapting behaviors and content to maintain user interest.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If virtual agents use standardized interactions, then implementation is simple and cost-effective, but user engagement and retention deteriorate due to monotonous experiences

Engineering Contradiction:
Improveimplementation simplicityVSAvoiduser engagement
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The virtual agent system dynamically adapts its persona characteristics (visual appearance, audio presentation, behavior patterns) based on real-time analysis of user data, transaction context, and feedback. This allows the same virtual agent to provide personalized, engaging interactions without requiring multiple static agent implementations, resolving the contradiction between implementation simplicity and user engagement.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system modifies parameters of the virtual agent's persona (visual characteristics, audio properties, behavioral traits) based on user preferences and transaction context. By changing these parameters dynamically, the system maintains implementation simplicity while significantly improving user engagement and retention through personalized interactions.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If virtual agents provide personalized interactions using AI and IoT data, then user engagement improves, but system complexity and data processing requirements worsen

Engineering Contradiction:
Improveuser engagementVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system segments the persona customization into distinct components (visual appearance, audio presentation, behavior patterns) that can be independently selected and combined. This modular approach allows personalized interactions to be achieved through structured data processing rather than complex monolithic systems, improving user engagement while managing system complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The virtual agent system is designed to perform multiple functions: analyzing user data from IoT devices, processing transaction context, selecting appropriate persona characteristics, and dynamically adapting interactions. This multi-functionality consolidates what would otherwise require separate systems into a single platform, improving engagement without proportionally increasing complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Duration of action of stationary object

If virtual agents adapt behaviors in real-time based on user feedback, then user retention improves, but processing time and computational resources worsen

Engineering Contradiction:
Improvesession durationVSAvoidprocessing time
Core Design Contradiction:
Duration of action of stationary objectVSLoss of time

Solution Approach 1:

The system pre-processes and stores user preference data, persona characteristics, and interaction patterns before actual transactions occur. By having this data prepared in advance, the virtual agent can quickly adapt its behavior during real-time interactions without excessive processing delays, thereby extending session duration without significant time loss.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements continuous feedback loops where user responses to virtual agent interactions are immediately analyzed and used to adjust persona characteristics. This real-time feedback mechanism allows the agent to adapt behaviors during the session, improving retention while keeping processing time manageable through efficient data utilization.

Inventive Principle:
Principle #23Feedback

AI summary

Systems, methods and/or computer program products personalizing user interactions with virtual agents of applications and/or services, using audio/visual components customized to appeal to user preferences. Upon initial interaction with virtual agents, AI ranking algorithms are triggered to adopt the highest ranked persona for the virtual agent based on previous positive interactions with the user, learned preferences, the user's state inferred from facial expressions, body language, tone. Personas can emulate voice signatures of popular characters, actors, celebrities and sports figures, and access a corpus of dialogue of the available personas to learn unique speech patterns, slang, tone, grammar, speed, and vocabulary. The corpus that comprises various personas of real and/or fictional individuals can include data of the mannerisms and visual likeness of the various characters and people, allowing avatars depicting the virtual agents to be animated in the likeness of the selected persona in real-time during conversational workflows.
