Gaze-Based Display Control for Unintended Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing technologies that rely on eye movement for input often unintentionally accept user inputs when the user is not consciously interacting with the screen, leading to unintended screen displays and user discomfort due to explicit variations.
Innovation Solution
An information processing apparatus that detects a user's gaze point and estimates their intention to subtly vary the screen display, allowing for implicit adjustments based on detected gaze patterns without requiring explicit user input, using a detection unit, estimation unit, image generation unit, and display control unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If explicit screen variation is performed based on detected eye movement, then input functionality is enabled, but unintended inputs occur when user sees screen unconsciously
Solution Approach 1:
The system performs preliminary detection of gaze position and duration before executing any input action. By monitoring how long the user's gaze remains fixed on a particular area (threshold time period), the system ensures that only intentional viewing triggers input functionality, preventing accidental activations from unconscious glances.
Solution Approach 2:
The system provides feedback by requiring sustained gaze attention rather than momentary eye movement. This feedback mechanism filters out unconscious viewing behavior and confirms intentional user focus, thereby improving input reliability while maintaining automation.
2Productivity
If explicit screen variation is performed based on eye movement input, then input operations are executed, but user discomfort occurs due to unintended operations
Solution Approach 1:
The system performs preliminary verification by measuring gaze duration against a threshold time period before executing any screen variation or input operation. This preliminary check ensures that only deliberate user intentions result in operations, eliminating unintended actions that cause discomfort.
Solution Approach 2:
The system applies preliminary anti-action by preventing execution of screen variation until intentional gaze is confirmed. This counter-measure blocks potential harmful unintended operations before they can occur, thereby eliminating user discomfort while preserving productive operations.
3Reliability
If manual operation is required for all screen interactions, then input accuracy is maintained, but operational burden increases
Solution Approach 1:
The system enables self-service by automatically detecting user intent through sustained gaze patterns and executing corresponding screen variations without requiring manual confirmation. This allows the system to serve itself by interpreting visual attention as implicit command, reducing operational burden while maintaining accuracy through the threshold-based intention verification.

AI summary
There is provided an information processing apparatus including a detection unit configured to detect a gaze point of a user in a display image displayed on a display unit, an estimation unit configured to estimate an intention of the user based on the gaze point detected by the detection unit, an image generation unit configured to generates a varying image that subtly varies from the display image to a final display image according to the intention estimated by the estimation unit, and a display control unit configured to control the display unit in a manner that the varying image generated by the image generation unit is displayed.
