Transparent Display Gaze Segmentation for Multi-User Information Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transparent displays struggle to accurately display information to multiple users simultaneously, leading to confusion and incorrect information viewing due to overlapping sight lines and lack of interaction with real objects.
Innovation Solution
An information display method and apparatus that detects multiple users' gaze ranges, calculates their intersection, and adjusts the display of object information based on a preset ratio, ensuring correct information is shown to each user by integrating or separating object information according to their gaze ranges and object categories.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If object information is displayed at the position where user sight lines fall on the transparent display, then the information can be viewed by users, but multiple users may view wrong information due to intersecting sight lines
Solution Approach 1:
The transparent display is divided into multiple display regions based on individual user gaze ranges. Each user is assigned a dedicated display region corresponding to their gaze area, preventing information overlap and ensuring that each user views only the intended information. This segmentation resolves the contradiction by maintaining information accuracy while managing display control through region-based assignment.
Solution Approach 2:
Different display regions are assigned different display characteristics based on local user gaze patterns. The system identifies individual gaze ranges and creates localized display zones with appropriate information content for each user's viewing position. This local quality approach ensures information accuracy for each user while the system manages complexity through automated gaze-based region identification.
2Adaptability or versatility
If the same transparent display is used by multiple users, then resource sharing is achieved, but it becomes difficult for all users to view correct display information
Solution Approach 1:
The display system dynamically adjusts display regions and information content based on real-time user gaze detection. When multiple users are present, the system continuously identifies individual gaze ranges and reconfigures display regions accordingly. This dynamic adaptation enables multiple users to share the same display while maintaining information accuracy for each user through automated gaze-based region assignment.
3Quantity of substance
If repeatedly displayed object information is shown to multiple users, then information availability is maintained, but user confusion increases due to overlapping display content
Solution Approach 1:
The display content is segmented into user-specific regions based on individual gaze ranges. Each user receives information tailored to their viewing position, preventing overlapping information that causes confusion. This segmentation maintains information availability for all users while eliminating the harmful effect of user confusion by ensuring each user views only relevant information.
Solution Approach 2:
The gaze detection system acts as an intermediary between the display content and multiple users. It detects user gaze positions and uses this information to mediate the distribution of display content, assigning appropriate information to each user based on their gaze range. This intermediary approach maintains information availability while preventing user confusion through intelligent content routing.

AI summary
An information display method and an information display apparatus suitable for multi-person viewing are provided. The method is adapted to an electronic apparatus having a transparent display and a processor, and the method includes following steps: detecting a plurality of users viewing the transparent display, and calculating a gaze range of each user viewing the transparent display; calculating an intersection range of the gaze ranges of the users and determining whether a ratio of the intersection range to the gaze ranges exceeds a preset intersection ratio; displaying object information of the objects appeared in the gaze range according to each of the gaze ranges if the ratio does not exceed the preset intersection ratio; and displaying object information of the objects appeared in the gaze range according to the intersection range if the ratio exceeds the preset intersection ratio.
