Vehicle Conversational Agent Selection and Personalization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle conversational agents are preconfigured and not modifiable, limiting user choice and personalization, as they are adapted to an average user profile and rely on a limited set of criteria, which can lead to dissatisfaction among users with varying preferences.
Innovation Solution
An assistance device with voice recognition and control means that allows users to select from various conversational agents, each with predefined criteria for intervention modes and rights, enabling customization based on user needs, including options like coach, benefactor, butler, and friend types, and allowing modification of preconfigured criteria in an expert mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single pre-configured conversational agent is used, then the system complexity is reduced and ease of manufacture is improved, but user satisfaction and adaptability deteriorate because the agent cannot be modified to suit individual user preferences
Solution Approach 1:
The patent segments the single conversational agent into multiple independent agents, each with its own pre-configured personality and intervention style. Users can select from different agents (e.g., authoritative, supportive, neutral) to match their preferences. This segmentation resolves the contradiction by providing adaptability through multiple specialized agents rather than one general agent, while each agent remains independently configured to manage system complexity.
Solution Approach 2:
The patent introduces dynamic configurability where users can adjust intervention parameters such as authority level, supportiveness, and information provision in real-time. The system transitions from static pre-configuration to dynamic adaptation, allowing users to modify agent behavior based on their needs. This dynamic approach enables personalization without requiring complete system redesign, balancing adaptability with manageable complexity.
2Adaptability or versatility
If intervention parameters are made modifiable, then user personalization is improved, but the ease of operation deteriorates due to the increased complexity of configuration
Solution Approach 1:
The patent applies preliminary action by providing pre-configured conversational agents with default personality profiles and intervention styles before user interaction. Users start with ready-to-use agents that require minimal configuration, and can later adjust parameters if needed. This approach resolves the contradiction by offering personalization through pre-configured options that are easy to select, while detailed configuration remains available but not mandatory.
Solution Approach 2:
The patent enables parameter changes by allowing users to modify specific intervention parameters (authority, supportiveness, information provision) without changing the entire agent configuration. Users can adjust individual parameters independently, making personalization simpler and more manageable. This selective parameter modification resolves the contradiction by providing customization capability while maintaining operational simplicity through incremental adjustments.
3Adaptability or versatility
If multiple conversational agents with different personalities are provided, then user satisfaction is improved, but the device complexity increases due to multiple configuration sets
Solution Approach 1:
The patent segments the conversational agent system into multiple independent agents, each with its own pre-configured personality and intervention style. This segmentation allows the system to manage complexity by treating each agent as a separate, self-contained unit with its own configuration, rather than one complex configurable system. Users can select from pre-defined agent types, reducing the burden of configuration management while maintaining high adaptability.
4Ease of operation
If pre-configuration is made fixed, then system stability is improved, but user satisfaction deteriorates due to lack of customization options
Solution Approach 1:
The patent introduces dynamic configurability that allows users to adjust intervention parameters in real-time while maintaining stable agent identities. The system transitions from static pre-configuration to dynamic adaptation, where agents can modify their behavior based on user preferences without changing their core personality. This dynamic approach resolves the contradiction by providing both stability (through defined agent personalities) and flexibility (through adjustable parameters).

AI summary
A device (DA) for assisting a user of a vehicle (V) comprising equipment suitable for performing tasks. This device (DA) comprises: - voice recognition means (MR) for recognising words and expressions uttered by the user, and - control means (MC) suitable both for proposing to the user a list of conversational agents in order that he selects one of these, each conversational agent being suitable for conversing with the user, at least for proposing the performing of a task or tasks, and/or for automatically triggering the performance of a task or tasks, according to a predefined associated set of preconfigured criteria each defining at least one mode or right of action, as well as for operating the conversational agent selected by the user, automatically or when a word or an expression uttered by the user has been recognised.
