Gaze-Based Content Display Control for User Concentration

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing technologies fail to accurately determine whether a user is concentrating on a task using a work medium, leading to inappropriate display modes of content images and inability to suppress the decline in user concentration.

Innovation Solution

An information processing method that determines whether a user's gaze is directed toward a work medium and adjusts the mode of the displayed content image to reduce visual attention when the user is concentrating, using techniques such as obscuration, luminance reduction, and content switching.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If content images are displayed on the display to enhance user experience, then user satisfaction is improved, but user concentration on the work medium deteriorates

Engineering Contradiction:

Improveuser satisfactionVSAvoiduser concentration

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The system dynamically adjusts the display mode of content images based on real-time detection of user gaze direction. When the user's gaze is directed toward the work medium, the content image display is modified (e.g., obscured, dimmed, or replaced) to reduce visual distraction. This dynamic adaptation allows the system to maintain user satisfaction through content display while preventing deterioration of concentration on work tasks.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system applies different display qualities to different regions or aspects of the visual output. Specifically, when user concentration is detected, the content image displayed in the periphery or background is rendered with reduced quality (e.g., lower resolution, obscured, or dimmed), while the work medium remains clearly visible. This local differentiation allows content to be present without competing for the user's focused attention.

Inventive Principle:

Principle #3Local quality

2Extent of automation

If existing technologies detect user concentration through head movement or body movement, then some indication of concentration state is obtained, but accurate determination of gaze direction toward work medium is not achieved

Engineering Contradiction:

Improveconcentration detectionVSAvoidgaze direction determination

Core Design Contradiction:

Extent of automationVSMeasurement precision

Solution Approach 1:

The system replaces mechanical detection methods (head movement sensors, body movement sensors) with optical detection methods. By using a camera to capture images of the user's face and eyes, and applying image processing algorithms to determine gaze direction, the system achieves more precise measurement of whether the user is looking at the work medium. This substitution of detection mechanism enables accurate gaze direction determination that mechanical sensors cannot provide.

AI summary

An information processing device displays a content image on a display, determines whether or not a user's gaze is directed toward a work medium for the user to perform a task, and performs, in a case where it is determined that the user's gaze is directed toward the work medium, a process for changing a mode of the content image displayed on the display so that a level of visual attention of the user decreases.
