Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for providing interaction in mobile bodies, such as vehicles, require complex configurations to recognize the situation of passengers and provide synchronized virtual images and voice outputs, lacking simplicity in detection and control.
Innovation Solution
A mobile body with a steering unit and an operation terminal holding unit that detachably holds an operation terminal with an attitude change detection unit, allowing for recognition of the passenger's situation and execution of interaction control using output devices like displays and speakers based on detected attitude changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional systems use multiple sensors (in-vehicle camera, microphone, seating sensor, exterior camera, navigation device) to detect passenger situation and provide interaction, then the interaction recognition accuracy is improved, but the device complexity increases
Solution Approach 1:
The patent extracts the essential function of passenger situation detection from a complex multi-sensor system and implements it using a simple attitude change detection unit in the operation terminal. The operation terminal's attitude detection unit alone can recognize driver situation, eliminating the need for multiple sensors while maintaining recognition accuracy.
Solution Approach 2:
The operation terminal serves multiple functions: it is both the steering control device and the situation detection device. The attitude change detection unit in the operation terminal can detect both steering operations and driver situation, making the system more universal and less complex.
2Ease of operation
If the operation terminal is detachably held in the steering unit, then the ease of operation and adaptability are improved, but the reliability of continuous detection may worsen
Solution Approach 1:
The operation terminal holding unit provides a dynamic solution that adapts to different usage scenarios. The holding unit can maintain the terminal in various positions (attached or removed) while ensuring that attitude change detection continues to function reliably for interaction control purposes.
