Arousal Level Prediction Using Biological and Environmental Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for predicting arousal levels in users, such as drivers, often require strong stimuli to counteract decreased arousal, which can be disruptive and unsafe, especially when the user is driving.
Innovation Solution
A method and apparatus that predict future arousal levels by combining current biological information from sensors like heart rate and respiratory rate with environmental data, allowing for the issuance of notifications or control of devices like air conditioners or lighting to maintain arousal without strong stimuli.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If strong stimuli are used to counteract decreased arousal levels, then the arousal level can be restored, but the user experiences disruption and safety risks especially when driving
Solution Approach 1:
The system performs preliminary action by predicting future arousal levels before the user actually becomes drowsy. By analyzing current biological information and environmental factors, the system forecasts arousal level decreases and issues notifications in advance, allowing the user to take corrective action before strong stimuli are needed.
Solution Approach 2:
The system applies preliminary anti-action by counteracting the predicted decrease in arousal level before it fully manifests. By issuing notifications and controlling devices based on predicted future arousal levels, the system prevents the harmful effects of strong stimuli from being necessary in the first place.
2Measurement precision
If arousal level is monitored continuously using multiple sensors, then prediction accuracy improves, but device complexity increases
Solution Approach 1:
The system merges multiple information sources including biological information from various sensors and environmental information from separate sensors into a unified prediction model. This integration allows accurate prediction of future arousal levels while managing system complexity through coordinated operation of multiple components.
Solution Approach 2:
The prediction apparatus serves multiple functions: it monitors current arousal levels, predicts future arousal levels, issues notifications, and controls external devices. This multi-functionality is achieved through a single integrated system that processes both biological and environmental data to accomplish various arousal management tasks.
Data Source
AI summary
A method for predicting an arousal level used by a computer of an arousal level prediction apparatus that predicts an arousal level of a user is provided. The method includes obtaining current biological information regarding the user detected by a sensor, and calculating a current arousal level of the user based on the current biological information. The method further includes obtaining current environment information indicating a current environment around the user, and predicting a future arousal level, which is an arousal level a certain period of time later, based on the current arousal level and the current environment information. Based on the predicted future arousal level, the method further issues a notification to the user, or controls an operation of a device.
