Lamp Posture Detection via Image Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Infrared focal length detection methods used in smart lamps for detecting sitting posture are prone to errors and have poor sensitivity, leading to unsatisfactory performance in accurately determining and correcting human body posture.
Innovation Solution
A lamp equipped with an image capturing unit and a processing unit that captures a target image of a desktop, determines reference information based on head features, and assesses whether the user is in a poor sitting posture, with optional reminder and instruction units to alert the user and adjust the lamp position for accurate detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If infrared focal length detection is used to detect sitting posture, then the detection function is provided, but the measurement precision and reliability are poor
Solution Approach 1:
The patent replaces the infrared focal length detection system with an image capturing unit that takes photographs of the user. This substitution transitions from indirect infrared measurement to direct visual capture, significantly improving measurement precision for posture detection while enhancing reliability through image-based analysis
Solution Approach 2:
The patent introduces an image capturing unit as an intermediary between the user and the detection system. This intermediary captures visual information that can be processed to determine sitting posture, providing more accurate and reliable detection compared to direct infrared focal length measurement
2Measurement precision
If image capturing unit is added to the lamp, then the sitting posture detection accuracy is improved, but the device complexity increases
Solution Approach 1:
The patent merges the image capturing unit with the lamp structure, integrating multiple functions (illumination and posture detection) into a single device. This combination improves detection accuracy while minimizing the increase in device complexity by sharing the lamp's structural components
Solution Approach 2:
The lamp is designed with multi-functionality, serving both as an illumination device and a sitting posture detection device. The image capturing unit enables the lamp to perform posture detection without requiring a separate dedicated detection device, thereby improving accuracy while controlling complexity through functional integration

AI summary
A lamp and a method for detecting a user's sitting posture are provided. The lamp is adapted to detect the user's sitting posture. The lamp comprises a lamp bracket, an image capturing unit and a processing unit. The image capturing unit is disposed on the lamp bracket and configured to capture a target image towards a desktop. The processing unit is coupled to the image capturing unit, wherein in response to that a head feature exists in the target image, the processing unit is configured to determine a reference information according to the head feature and to determine whether the reference information meets a poor sitting posture condition.
