Transparent Display Gaze Tracking for Unblocked Doctor-Patient Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing medical treatment systems hinder gaze exchange and information transfer between doctors and patients, leading to reduced patient satisfaction and treatment efficiency due to blocked gazes and increased reliance on electronic charts, which disrupt direct communication.
Innovation Solution
A medical treatment system utilizing a transparent display module with integrated gaze trackers and a control unit to rearrange interface windows based on detected gaze points, ensuring uninterrupted gaze exchange and information transfer by relocating windows outside the gaze exchange region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a monitor is used separately to provide information, then information exchange is improved, but gaze exchange between doctor and patient deteriorates
Solution Approach 1:
The patent combines the information display function and gaze exchange function into a single transparent display device. The transparent display shows medical chart information while allowing the doctor to maintain visual contact with the patient, merging what were previously separate functions (monitor for information, face-to-face for gaze) into one integrated solution.
Solution Approach 2:
The transparent display acts as an intermediary that overlays information in the doctor's visual field without blocking the view of the patient. It mediates between the need for information access and the need for gaze contact by making the display visually permeable, allowing both functions to coexist simultaneously.
2Loss of information
If a doctor observes electronic charts during treatment, then information access is improved, but gaze exchange with patient deteriorates
Solution Approach 1:
The system merges the electronic chart display with the doctor-patient interaction space by placing the transparent display in the doctor's field of view. This allows the doctor to access medical information and maintain gaze with the patient simultaneously, eliminating the time loss associated with shifting attention between separate devices.
Solution Approach 2:
The transparent display dynamically adjusts its content and positioning based on the doctor's gaze direction and treatment context. The system can prioritize different information elements depending on the diagnostic phase, allowing the doctor to access relevant information without breaking visual contact with the patient.
3Loss of information
If a monitor is placed between doctor and patient, then information provision is improved, but rapport and satisfaction deteriorate
Solution Approach 1:
The transparent display serves as a non-intrusive intermediary that provides information without disrupting the interpersonal connection. Unlike traditional monitors that physically block interaction, the transparent display mediates information delivery while maintaining visual permeability, allowing doctor and patient to continue building rapport.
Solution Approach 2:
The transparent display utilizes optical properties including transparency and potential color/transparency adjustments to minimize its visual impact on the doctor-patient interaction. By being visually subtle and adaptable, it provisions information without dominating the interaction space or reducing the perceived warmth of the encounter.

AI summary
A medical treatment system includes a transparent display located between a patient and a medical staff and configured to display, a plurality of interface, first and second gaze trackers respectively mounted on both sides of the transparent display to detect pupils of the medical staff and patient and configured to acquire positional coordinates of the pupils of the medical staff and patient in a three-dimensional space, a region setting unit configured to set a gaze exchange region based on an intersection point where a virtual connection line between the positional coordinates of the pupils of the medical staff and patient intersects a plane of the transparent display, and a control unit configured to rearrange the plurality of interface windows by moving at least one interface window overlapping the gaze exchange region outside the gaze exchange region.
