Display Control Device Visual Field Detection Peripheral Alerting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display control technologies fail to effectively reduce the loss of opportunity for individuals to view content, as they do not account for situations where a person is within the visual field of a display device but not directly facing it.
Innovation Solution
A display control device and method that include a visual field determination unit, a central visual field determination unit, and a change determination unit. These units assess whether a display device is within a person's visual field and central visual field, and determine if the display mode should be temporarily changed before content switching, ensuring that individuals in the peripheral visual field are alerted to the content change.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If content is displayed only when a person is directly facing the display device (central visual field), then content display accuracy is improved, but the loss of opportunity to watch content increases for persons in peripheral visual field
Solution Approach 1:
The system performs preliminary detection of the viewer's visual field state before content switching occurs. When a viewer is detected in the peripheral visual field, the system prepares and executes display mode changes in advance to attract attention, ensuring the viewer can watch the content without missing the opportunity due to not being in the central visual field.
Solution Approach 2:
The display mode is made dynamic and adaptable based on the viewer's visual field position. The system automatically adjusts the display mode between normal mode and attention-attracting mode according to whether the viewer is in the central or peripheral visual field, optimizing both content display accuracy and viewer engagement opportunity.
2Loss of time
If the display mode is frequently changed to attract peripheral viewers, then the opportunity to watch content is improved, but the device complexity increases
Solution Approach 1:
The attention-attracting display mode changes are applied locally and temporarily only when needed for peripheral viewers, rather than continuously or system-wide. This selective application reduces the overall complexity burden while maintaining the benefit of increased viewer engagement opportunities.
Solution Approach 2:
The system uses feedback from the visual field detection unit to automatically determine when display mode changes are necessary. This closed-loop control reduces the need for complex manual control mechanisms, as the system self-adjusts based on real-time detection of viewer position and attention state.
3Loss of time
If the display mode is changed to alert peripheral viewers, then viewer engagement is improved, but the ease of operation deteriorates due to automatic control
Solution Approach 1:
The display control device performs self-service by automatically detecting viewer position and autonomously adjusting display modes without requiring manual intervention. This eliminates the need for users to manually control display settings, improving ease of operation while maintaining high viewer engagement through appropriate display mode selection.

AI summary
A display control device includes a visual field determination unit configured to determine whether or not a display device for displaying content is included in a visual field of a person included in an image captured by an imaging device that images a region around the display device, a central visual field determination unit configured to determine whether or not the display device is included in a central visual field within the visual field, and a change determination unit configured to determine whether or not to temporarily change a display mode of the display device displaying first content before the content is switched from the first content displayed on the display device to second content to be subsequently displayed when it is determined that the display device is included in the visual field but is not included in the central visual field.
