Eye Detection Smart Glasses for Medical Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional medical equipment using VR, AR, and MR technologies often cause gaze dispersion in doctors during diagnosis and surgery, leading to reduced concentration and potential safety risks due to the need to alternate between viewing patients and separate monitor screens for information.
Innovation Solution
An eye detection-based smart glasses display device that uses distance measurement units to detect the user's eye direction, an image acquisition unit to acquire overlay images, and a screen synthesis unit to compute and display relevant information at a designated location on a smart glasses-type display, ensuring the doctor's gaze remains focused on the patient or surgical site.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional medical equipment uses separate monitor screens for displaying information, then information can be displayed clearly, but the doctor's gaze disperses between the patient and the monitor
Solution Approach 1:
The patent combines the information display function with the smart glasses worn by the doctor, merging the monitor screen into the eyewear. This allows the doctor to view patient information and diagnostic data directly through the glasses while maintaining focus on the patient, eliminating the need to shift gaze between separate monitors and the patient.
Solution Approach 2:
The smart glasses act as an intermediary device between the doctor and the information display system. The glasses capture the doctor's eye direction and use this information to dynamically adjust and display relevant information in the appropriate visual field, serving as a mediator that delivers information without requiring the doctor to look away from the patient.
2Ease of operation
If the doctor turns the head to view required information, then information can be accessed, but the treatment precision and patient safety are compromised
Solution Approach 1:
The system dynamically adjusts the display of information based on the doctor's real-time eye direction and head position. As the doctor moves their gaze or head, the system automatically updates which information is displayed and where it appears in the visual field, allowing continuous access to required information without requiring deliberate head turns that would compromise treatment precision.
3Reliability
If VR, AR, and MR technologies are introduced to maximize doctor concentration, then gaze dispersion is reduced, but the device complexity increases
Solution Approach 1:
The smart glasses integrate multiple functions into a single device: eye direction detection, image capture, information processing, and dynamic display adjustment. By combining these functions into one universal device worn by the doctor, the system achieves the concentration benefits of VR/AR/MR technologies without the complexity of multiple separate systems.

Function Achieved in This Case
The device effectively prevents gaze dispersion by displaying critical information in a specific area based on the doctor's eye motion, allowing for more accurate diagnosis and surgery without diverting attention from the patient or surgical site.
