Display Control Unit for Digital Signage with Person Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital signage systems fail to effectively engage targets by not clearly indicating the next content to be magnified, leading to a weakened appealing effect and reduced purchase desire.
Innovation Solution
An information processing device with a display control unit and detection unit that changes content in a candidate area based on the presence and attributes of a person within the effective range, ensuring the most viewed content is displayed in the main area, thereby maintaining target engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple pieces of content are displayed on a screen divided into parts of equal size, then content variety is improved, but the appealing effect to engage targets is weakened because the next content to be magnified is not clearly indicated
Solution Approach 1:
The display screen is divided into a main area for displaying the current content and a candidate area for displaying the next content to be magnified. This segmentation clearly indicates the progression of content, maintaining appeal while providing variety.
Solution Approach 2:
The candidate area displays the next content to be magnified in advance, preparing the viewer for the upcoming content change. This preliminary indication maintains viewer engagement and appeal while showcasing content variety.
2Ease of operation
If the next content to be magnified is not clearly indicated, then content display simplicity is maintained, but the appealing effect that causes target persons to remain within the effective range is weakened
Solution Approach 1:
The display is segmented into distinct main and candidate areas, providing clear visual guidance about content progression without complicating the overall display structure or operation.
3Productivity
If content is changed based on detected persons, then content appeal to targets is improved, but device complexity increases due to addition of detection unit and control logic
Solution Approach 1:
The system uses a detection unit to identify persons within the effective range and their line of sight direction, providing feedback to the display control unit. This feedback mechanism enables dynamic content adjustment based on viewer presence and attention, enhancing appeal while managing complexity through structured control logic.
Solution Approach 2:
The display control unit acts as an intermediary between the detection unit and the content display system, processing detection results and determining appropriate content changes based on person attributes and line of sight, thereby managing system complexity through a dedicated control layer.

AI summary
At least a main area and a candidate area are provided on a display screen of a display device, and a display control unit that causes content displayed in the candidate area when reproduction of content displayed in the main area ends to be displayed in the main area, and a detection unit that detects a person from a captured image of at least a place where the display screen is visually recognizable are included, wherein the display control unit changes the content displayed in the candidate area depending on the person during reproduction of the content displayed in the main area.
