Dynamic Display Orientation for Multi-User Flat Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When multiple operators are seated around a display screen placed flat on a desk, the operational environment becomes uncomfortable for operators on the opposite side, as displayed objects appear upside-down, disrupting instantaneous understanding and operability.
Innovation Solution
An information processing apparatus with a detecting unit to determine touch positions and display control units that rearrange and display objects in a predetermined direction based on the line connecting the touch positions, ensuring objects are displayed upright regardless of the operator's direction relative to the screen, allowing intuitive and stress-free operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the display screen is placed flat on the desk to allow multiple operators to work together, then the quantity of operators can be increased, but the objects displayed become upside-down for operators on the opposite side, worsening the ease of operation
Solution Approach 1:
The display control unit dynamically adjusts the display orientation of objects based on the detected touch position. When a touch is detected, the system determines the operator's direction relative to the display screen and rotates the objects to be displayed upright from that operator's perspective. This dynamic adaptation allows multiple operators to work comfortably from different positions around the flat display screen.
2Ease of operation
If the display screen is placed upright to provide a comfortable operational environment, then the ease of operation is improved, but the display cannot accommodate multiple operators seated around the screen, reducing the quantity of operators
Solution Approach 1:
The system maintains the flat display screen orientation but dynamically rotates individual objects based on the operator's position. When multiple operators are detected, each operator sees objects oriented upright from their respective perspectives, enabling collaborative work around the screen while maintaining operational comfort for all users.
3Device complexity
If objects are displayed in a fixed predetermined direction, then the device complexity is reduced, but objects may appear upside-down to operators on the opposite side, worsening the ease of operation
Solution Approach 1:
The display control unit incorporates dynamic rotation capability that activates only when needed. Objects are displayed in a predetermined direction by default, but when a touch is detected, the system calculates the operator's direction and rotates objects accordingly. This approach adds minimal complexity while significantly improving operational comfort for operators at various positions.
Solution Approach 2:
The system changes the orientation parameter of displayed objects based on the detected touch position. By adjusting the rotation angle parameter dynamically, the system ensures objects are always displayed upright relative to the operator's viewing direction, regardless of their position around the flat display screen.

AI summary
A user interface technique with excellent operability for displaying an object to be selected upright for an operator who operates a display screen of a display device from any direction. For this purpose, when the operator touches the display screen with his/her index finger, menu icons are displayed on a circumference with the touch position as a center, and with the central position of the circle as a lower position, at equal intervals. At this time, when the operator touches the display screen with his/her thumb while touching the display screen with his/her index finger, it is determined that the operator exists on an extension line on the thumb touch position side defined with the two touch positions. Then the respective menu icons are rearranged so as to be displayed upright from the operator.
