Adaptive Display Control for Variable User Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices with large screens installed on walls, floors, or tables face challenges in improving user operability and visibility due to variable user positions and angles, as existing techniques struggle to effectively control screen content based on user line of sight.
Innovation Solution
A display control device and method that includes a screen control unit generating objects and arranging them consecutively in a transverse direction, acquiring user information such as positional and line of sight data, and controlling the screen accordingly to optimize content presentation for multiple users and dynamic user positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a large screen display device is installed on a wall, floor, or table, then the screen size and visibility are improved, but the positional relation between the user and the display device becomes variable, making it difficult to improve operability and visibility
Solution Approach 1:
The patent applies dynamics by making the screen control adaptive and flexible rather than fixed. The screen control unit dynamically adjusts screen generation and control based on real-time user position information acquired by the position acquiring unit. This allows the display system to adapt to various installation positions (wall, floor, table) and user positions, resolving the contradiction between large screen size and ease of operation.
2Area of stationary object
If the display device is equipped with a large screen, then the visual impact is improved, but controlling the display position based on line of sight becomes difficult due to variable user positions and angles
Solution Approach 1:
The patent introduces position information as an intermediary parameter between the user and the screen control system. Instead of directly detecting line of sight, the position acquiring unit acquires user position information which then serves as the basis for screen control. This intermediary approach simplifies the detection process and works effectively with various installation positions and user angles.
3Ease of operation
If screen control is based on fixed line of sight detection, then operability for a single user is improved, but adaptability to multiple users and various installation positions deteriorates
Solution Approach 1:
The patent implements universality by designing a screen control system that can serve multiple users and various installation positions through a unified approach. The position acquiring unit acquires user position information that works regardless of installation position (wall, floor, table), and the screen control unit generates screens adapted to each user's position. This makes the system universally applicable to different scenarios while maintaining good operability.
