Speech Interaction Icons for Interrupted In-Vehicle Notifications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to effectively remind users of interrupted notification information, leading to forgotten content upon resumption.
Innovation Solution
A speech interaction device that recognizes interaction contents before interruption, extracts keywords, and generates an icon image representing the interaction contents using a processor and database, ensuring the user remembers the information upon resumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If notification information is restrained from display when driving load is high, then driver safety is improved, but user memory of the notification content deteriorates
Solution Approach 1:
The system performs preliminary action by generating and displaying an icon image that represents the notification content before the notification is fully displayed or before the interaction is interrupted. This icon serves as a preview or summary that the user can see in advance, ensuring they remember the content even if the full notification is delayed or interrupted due to high driving load.
Solution Approach 2:
The system creates a simplified copy of the notification content in the form of an icon image. This icon is a visual representation that captures the essential meaning of the notification without requiring the user to process the full text or detailed information. The icon copy maintains the core information in an easily memorable format.
2Object-affected harmful factors
If speech interaction is interrupted during high driving load, then driver distraction is reduced, but context awareness deteriorates
Solution Approach 1:
The system displays the icon image representing the interaction content before the speech interaction is fully executed or before it needs to be interrupted. This preliminary visual cue ensures the driver understands what the interaction is about before engaging, and can refer back to it if the interaction is interrupted, maintaining context awareness without requiring continuous speech processing during high-load periods.
Solution Approach 2:
The icon image serves as an intermediary between the speech interaction system and the driver. It provides a visual medium that conveys the essence of the interaction content without requiring the driver to actively process speech or text during the interaction. This intermediary maintains the connection and context even when the full speech interaction is interrupted.

AI summary
A speech interaction device comprising a processor for controlling a speech interaction of a user, the processor configured to: recognize interaction contents of the user before interruption of the speech interaction; extract, on a basis of the interaction contents, a keyword in the speech interaction before the interruption as a pre-interruption keyword; to generate, on a basis of the extracted pre-interruption keyword, an icon image representing the interaction contents before the interruption; and generate a control command to display the generated icon image. The processor is configured to update, after the icon image is displayed, the icon image displayed to the user on a basis of a topic subject in which the user may have an interest and/or a driving load of the user who drives a vehicle during the interruption of the speech interaction.
