In-Vehicle Excitement Detection Using Multi-Feature Driver Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional terminal devices cannot accurately determine a driver's excitement state while driving, as they only assess movement in response to musical compositions without considering the driver's actual excitement level.
Innovation Solution
An excitement degree control device is mounted in a vehicle, equipped with cameras, microphones, and a GPS receiver, which calculates movement and sound feature amounts to determine the driver's excitement level and store this data for accurate assessment, using reference values to adjust for personal habits and driving conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a terminal device only determines whether a user moves according to a musical composition, then the device structure remains simple, but the accuracy of determining the user's excitement state deteriorates
Solution Approach 1:
The patent segments the excitement state determination into multiple independent measurement components: movement feature amount (from camera), sound feature amount (from microphone), and optionally heartbeat feature amount. Each component is measured separately and then integrated to form a comprehensive excitement state assessment, resolving the contradiction by breaking down the complex measurement task into manageable segments.
Solution Approach 2:
The control device is designed to perform multiple functions: it not only determines excitement state but also stores content information, movement features, sound features, and provides content recommendations. This multi-functional approach allows the device to achieve high measurement precision while justifying the increased complexity through enhanced versatility and utility.
2Measurement precision
If multiple feature amounts are measured to accurately determine excitement level, then measurement accuracy improves, but device complexity and data processing requirements worsen
Solution Approach 1:
The patent implements a feedback mechanism where the control device stores measured feature amounts and excitement states, then uses this stored data to provide content recommendations and adjust future measurements. This feedback loop optimizes data processing by learning from past measurements and reducing redundant computations, thereby managing complexity while maintaining high accuracy.
Solution Approach 2:
The device performs preliminary actions by pre-storing reference data, content information, and measurement parameters before actual excitement state determination is needed. This preliminary preparation reduces real-time processing complexity while enabling accurate multi-feature analysis when required.
