Vehicle Information Presentation Device with Dynamic Directional Markers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle information presentation systems lack affinity in exchanging information between the vehicle and the occupant, as they rely solely on automatic displays that do not ensure the occupant's attention or understanding of the intended information.
Innovation Solution
A vehicle information presentation device that includes a presentation section, a detection section, and a control section to move perceivable information along detected presentation directions, allowing information to be presented sequentially at multiple positions within the vehicle cabin, utilizing visual, auditory, or tactile means to enhance the occupant's awareness of the information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If information is automatically displayed at a predetermined position, then the display function is simple and reliable, but the affinity in information exchange between vehicle and occupant is insufficient
Solution Approach 1:
The presentation section is divided into multiple independent presentation units distributed at different positions within the vehicle cabin. Each unit can independently present information, allowing the system to convey information through multiple locations rather than a single fixed display, thereby enhancing information exchange affinity while maintaining individual unit reliability
Solution Approach 2:
The system dynamically determines presentation directions based on detected occupant states and selectively activates presentation units along the determined direction. This dynamic adaptation allows the system to respond to changing conditions while maintaining a relatively simple base structure, resolving the contradiction between reliability and complexity
2Reliability
If information is presented at multiple positions along a presentation direction, then the occupant's awareness of information is improved, but the device complexity increases
Solution Approach 1:
Multiple presentation units are provided, each capable of presenting the same type of information. This multi-functionality allows the system to improve information awareness by presenting at multiple positions while using standardized components, thereby limiting the increase in device complexity
Solution Approach 2:
The control section acts as an intermediary that intelligently selects which presentation units to activate based on detected presentation directions and occupant states. This mediation allows the system to achieve high information awareness through selective activation rather than requiring all units to be simultaneously active, thus managing device complexity
3Reliability
If the presentation system adapts to occupant's attention state, then the information exchange affinity is enhanced, but the detection and control complexity increases
Solution Approach 1:
The detection section continuously monitors occupant states and provides feedback to the control section, which adjusts the presentation direction and active presentation units accordingly. This feedback mechanism enhances information exchange affinity by adapting to occupant attention while using a modular detection-control architecture that limits overall system complexity
Solution Approach 2:
The system uses the occupant's own state information (detected by the detection section) to automatically adjust presentation without requiring external intervention. This self-service approach enhances affinity while avoiding the complexity of external control interfaces, as the system serves itself by adapting to detected conditions

AI summary
A presentation controller in a control device captures an image of a driver using an onboard camera of an occupant state detection section, and acquires a state of the driver that is detected in the captured image and represents the posture of the driver, and the position of part of the body of the driver. The presentation controller then uses road-vehicle inter-communication to acquire, as an event, information from a detector of an event detection section indicating a danger in front of the vehicle, and detects a presentation direction for the event. The presentation controller then controls a device of a presentation section so as to move a marker that is assistance information along a direction from the vehicle toward the driver, as information perceivable by the occupant. The presentation controller then notifies the event to the ears of the driver.
