Interactive Agent Platform Multimodal Interaction Architecture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies face challenges in designing interactive systems that can engage in flexible and robust multimodal interactions with users, particularly in creating natural and nuanced conversations with avatars or bots.
Innovation Solution
The development of an interactive agent platform that utilizes an interaction modeling language and API, which employs a standardized interaction categorization schema, supports multimodal human-machine interactions, backchanneling, and an event-driven architecture, enabling more complex and realistic conversational AI.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional chatbot systems with single interaction modality are used, then system simplicity is maintained, but the ability to engage in natural and nuanced multimodal interactions is limited
Solution Approach 1:
The system segments interaction processing into distinct modules: speech-to-text conversion, text-to-speech generation, and visual element generation. Each module handles a specific aspect of multimodal interaction, allowing the system to process multiple modalities simultaneously while maintaining manageable complexity through modular architecture.
Solution Approach 2:
The conversational AI model is designed to perform multiple functions: processing speech input, generating text responses, creating visual elements, and coordinating these different modalities. This multi-functional approach allows a single core model to handle diverse interaction types without requiring separate specialized systems for each modality.
2Loss of information
If turn-based text dialog is used, then interaction simplicity is maintained, but the ability to provide dynamic visual information and contextual responses is limited
Solution Approach 1:
The system pre-generates or pre-prepares visual elements that can be quickly deployed during conversations. Visual content is created in advance or cached based on anticipated conversation topics, allowing rapid display of contextual information without adding significant processing delay to the interaction flow.
Solution Approach 2:
A visual element generation module acts as an intermediary between the conversational AI model and the display interface. This intermediary translates text-based AI responses into appropriate visual representations, coordinating the timing and content of visual displays to enhance rather than complicate the overall interaction.
3Reliability
If highly realistic avatar interactions are created, then naturalness of interaction is improved, but subtle imperfections become more apparent causing the uncanny valley effect
Solution Approach 1:
The system applies different levels of realism to different aspects of the avatar interaction. Critical interaction elements such as facial expressions and eye contact maintain high realism to convey emotion and engagement, while less critical elements use simplified representations. This selective application of realism maintains naturalness in key areas while avoiding the uncanny valley in peripheral areas.
Solution Approach 2:
The avatar performs slightly exaggerated or stylized versions of human behaviors rather than attempting perfect replication. This partial action approach, where movements and expressions are intentionally enhanced rather than precisely copied, creates a more appealing and less unsettling interaction that avoids the uncanny valley while maintaining naturalness.

AI summary
In various examples, an interactive agent platform that hosts development and/or deployment of an interactive agent may use a GUI service to execute interactive visual content actions and generate corresponding GUIs. An interaction modeling API may use an interaction categorization schema that defines a standardized format for specifying (e.g., visual information scene, visual choice, or visual form actions) events that instruct an overlay of visual content supplementing a conversation with the interactive agent. The GUI service may translate a standardized representation of a GUI specified by an interaction modeling API event into a modular GUI configuration defining blocks of visual content specified by the event, and may use these blocks to populate a (e.g., template or shell) visual layout for a GUI overlay layout. As such, a visual layout representing a GUI specified by an interaction modeling API event may be generated and presented (e.g., via a user interface server).
