Concentration Estimation Using Image and Room Environment Sensors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Accurately recognizing a user's concentration degree from a video image is challenging due to various influencing factors associated with the user.
Innovation Solution
A concentration degree estimation apparatus that combines an imaging unit to capture user images with a sensor to gather room environment information, such as CO2 concentration and temperature, and an estimation unit to calculate the concentration degree based on both image data and environmental factors, including user age and sex.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If only image data from the imaging unit is used to estimate concentration degree, then the device complexity is low, but the measurement precision of concentration degree is insufficient
Solution Approach 1:
The patent combines multiple information sources (image data from imaging unit, room environment information from sensor, surface temperature from measuring unit) into a unified concentration degree estimation system. The estimation unit integrates these diverse data types to achieve more accurate concentration degree recognition than any single source could provide alone.
Solution Approach 2:
The air conditioner system is designed to perform multiple functions: it not only conditions the room environment but also estimates user concentration degree through integrated sensors and imaging units. This multi-functional approach allows the system to gather diverse data (environmental, visual, thermal) without requiring separate dedicated devices.
2Measurement precision
If multiple data sources (image, environment, temperature) are combined for estimation, then the measurement precision of concentration degree improves, but the device complexity increases
Solution Approach 1:
The air conditioner system is designed to perform multiple functions: it not only conditions the room environment but also estimates user concentration degree through integrated sensors and imaging units. This multi-functional approach allows the system to gather diverse data (environmental, visual, thermal) without requiring separate dedicated devices.
Solution Approach 2:
The air conditioner uses its own built-in sensors and imaging units to gather data for concentration degree estimation, rather than requiring external dedicated measurement devices. The system serves its own estimation needs through its existing hardware capabilities.
3Ease of operation
If the imaging unit is installed in the ceiling air conditioner, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The air conditioner is designed to perform multiple functions including both environmental conditioning and user monitoring. By integrating the imaging unit into the air conditioner, the system can simultaneously achieve room conditioning and concentration degree estimation without requiring separate installation of additional devices.
Solution Approach 2:
The patent combines multiple information sources (image data from imaging unit, room environment information from sensor, surface temperature from measuring unit) into a unified concentration degree estimation system. The estimation unit integrates these diverse data types to achieve more accurate concentration degree recognition than any single source could provide alone.
Data Source
AI summary
A camera takes an image of a user. A room environment information sensor detects room environment information about an environment in a room where the user is present. An estimation unit estimates a concentration degree of the user based on the image of the user taken by the camera and the room environment information sensed by the room environment information sensor.
