Dynamic Display Orientation Adjustment for Human Approach Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems fail to effectively consider the movement direction of humans approaching a display position, leading to inappropriate content and orientation of images projected, which can hinder effective alerting or communication.
Innovation Solution
A display system comprising a display apparatus, sensors, and a control apparatus that acquires and determines the movement direction of humans using sensors, and adjusts the image orientation and content accordingly to ensure it is displayed in an easily viewable format.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If image display does not consider human movement direction, then the display system is simple, but the alert effectiveness deteriorates
Solution Approach 1:
The display system dynamically adjusts image orientation based on real-time detection of human movement direction. The control apparatus receives movement direction information from the information processing device and rotates the displayed image accordingly, making the system adaptive rather than static. This resolves the contradiction by implementing just enough complexity (movement detection and image rotation) to significantly improve alert effectiveness without over-complicating the overall system.
Solution Approach 2:
The system establishes a feedback loop where the display apparatus receives information about human movement direction from sensors, processes this information, and adjusts the image orientation in response. This closed-loop control ensures the display adapts to actual viewing conditions, improving reliability while maintaining manageable system complexity through structured information flow.
2Adaptability or versatility
If image orientation is fixed, then the display apparatus is simple, but the adaptability to different viewing conditions deteriorates
Solution Approach 1:
The display apparatus transitions from fixed image orientation to dynamic adjustment based on detected movement direction. The control apparatus modifies the image rotation angle according to real-time sensor data, enabling the system to adapt to various viewing scenarios while maintaining a relatively simple overall architecture through modular control.
3Loss of information
If movement direction detection is added, then the alert relevance improves, but the sensor system complexity increases
Solution Approach 1:
The system extracts only the essential information needed for alert optimization - specifically movement direction - from the complex task of full human motion analysis. By focusing solely on directional data rather than complete movement patterns, the system reduces information processing requirements while still achieving improved alert relevance.
Solution Approach 2:
An information processing device serves as an intermediary between the sensor system and display control, processing movement direction data and translating it into control signals for image orientation. This mediator simplifies the overall system architecture by centralizing the complex processing task in a dedicated component rather than distributing complexity across multiple elements.

AI summary
A display method includes acquiring output corresponding to a movement direction of a human toward a display position of a display apparatus using a sensor, determining an orientation of a content used for alert based on the output corresponding to the movement direction, and displaying the content in the display position in the orientation using the display apparatus.
