Drive Assist Apparatus for Scenic Viewpoint Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers and passengers in vehicles often miss scenic landscapes while traveling due to uncertainty about the direction to focus their attention, leading to an unpleasant experience as they may not notice these viewsable only for a moment.
Innovation Solution
A drive assist apparatus and data collection system that include a processor, storage, and communication components to detect the line of sight and emotions of vehicle occupants and traffic participants, storing viewpoint data when positive emotions are detected, and providing notifications to direct attention to scenic viewpoints through a head-up display and voice guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If drivers and passengers rely on their own observation to notice scenic landscapes, then they maintain full control of their attention, but they miss scenic views because they cannot know the direction and timing in advance
Solution Approach 1:
The system performs preliminary detection of line of sight and emotion before the vehicle reaches the viewpoint, stores viewpoint data in advance, and provides notifications beforehand. This allows occupants to know the direction and timing of scenic views before they pass, preventing missed opportunities while maintaining system simplicity through selective data collection only when positive emotions are detected.
2Measurement precision
If the system continuously monitors line of sight and emotions to provide accurate viewpoint notifications, then notification accuracy improves, but processing load and energy consumption increase
Solution Approach 1:
The system applies partial monitoring by only performing full emotion and line of sight detection when specific conditions are met (e.g., when positive emotions are detected or when approaching known viewpoints). Rather than continuous monitoring, it uses selective detection triggers, reducing overall energy consumption while maintaining high precision when measurements are taken.
3Ease of operation
If the system provides detailed notifications about viewpoint directions, then occupants can accurately locate scenic views, but distraction from driving increases
Solution Approach 1:
The system uses an intermediary notification mechanism that provides viewpoint direction information through subtle cues (such as gentle visual indicators or audio prompts) rather than direct, attention-demanding commands. This intermediary approach guides occupants to scenic views without creating dangerous distractions, mediating between the need for information and the need for driving focus.
Data Source
AI summary
A drive assist apparatus includes a processor and a storage. The processor includes a line-of-sight detector, an emotion estimator, and a notification processing unit. The line-of-sight detector detects information on a line of sight of one or both of a vehicle occupant present in a vehicle and a traffic participant present around the vehicle. The emotion estimator estimates an emotion of the one or both of the vehicle occupant and the traffic participant. The storage stores, when the estimated emotion is detected as a positive emotion, data on a viewpoint including information on a position of the vehicle on map data and information on the line of sight. The notification processing unit makes, on the basis of the data on the viewpoint stored in the storage, a notification of information on a direction to notice to the vehicle occupant present in the vehicle traveling through a location corresponding to the viewpoint.
