Gaze-Triggered Extendable Display for Seamless Content Expansion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable electronic devices with rigid displays are limited in their ability to efficiently present large amounts of visual content, as they often require manual user interaction to extend or retract the display, which can be cumbersome and inefficient.
Innovation Solution
An electronic device with an extendable display that automatically extends in response to a user's gaze direction, interpreting eye movements as scrolling or panning gestures to present additional visual content without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual user interaction is required to extend or retract the display, then the display can be controlled precisely, but the operation becomes cumbersome and inefficient
Solution Approach 1:
The display system automatically extends or retracts based on detected user gaze direction, eliminating the need for manual interaction. The system serves itself by using the camera to monitor user attention and autonomously adjusting display configuration, thereby improving ease of operation and reducing time loss
Solution Approach 2:
The patent replaces manual mechanical interaction with an optical detection system (camera) and automated control algorithm. Instead of requiring physical button presses or gestures, the system uses gaze detection to trigger display extension, substituting mechanical user actions with an optical sensing and automated response mechanism
2Loss of information
If the display is extended to show more visual content, then the information presentation capacity increases, but the device complexity increases
Solution Approach 1:
The camera, originally designed for photography or video calls, is repurposed to detect user gaze direction for display control. This multi-functional use of existing hardware avoids adding dedicated sensors or complex control systems, thereby reducing device complexity while maintaining enhanced visual content presentation capability
Solution Approach 2:
The system uses the camera to create an optical copy or representation of user attention direction, which is then processed by software to determine when extension is needed. This approach avoids direct complex mechanical sensing and uses a simplified optical copying mechanism to trigger display changes

AI summary
An electronic device, method and computer program product enable an automatic increase in a size of a display to present more visual content responsive to a gaze direction. The electronic system monitors eye gaze direction. The electronic system presents a first portion of visual content on a flexible display while a flexible display support structure is at least partially retracted. In response to the visual content having an un-displayed second portion that is contiguous with the first portion and determining that the eye gaze direction has traversed the first portion towards one of a translatable edge of the flexible display support structure or an opposite edge of the first housing in a direction of the un-displayed second portion, the electronic system triggers the translation mechanism to extend the flexible display support structure. The electronic system presents the first and second portion of the visual content on an extended flexible display.
