Adaptive Display Output Direction for Inverted User Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users experience incongruity when interacting with devices having a user interface where the input and output directions are the same, especially when the relative angle between the input and display units exceeds 180°, making operations difficult.
Innovation Solution
An operation processing device that includes an input direction acquisition unit, an output direction indication unit, and a determination unit to adjust the output direction based on the relative position relationship between the input and display units, allowing the output direction to be aligned or opposite to the input direction depending on the angle, thus providing a more intuitive user interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a user interface with the same input and output direction is used, then the device structure is simplified, but user operation becomes incongruent when the relative angle between input unit and display unit exceeds 180°
Solution Approach 1:
The patent applies dynamics by making the output direction adaptive rather than fixed. The determination unit dynamically adjusts the output direction based on the relative angle between the input unit and display unit, switching between same-direction and opposite-direction modes. This dynamic adaptation resolves the contradiction by maintaining operational intuitiveness across different device configurations while keeping the interface structure relatively simple.
Solution Approach 2:
The patent changes the directional parameter of the output based on the relative angle parameter. When the relative angle exceeds a threshold (180°), the system switches the output direction from same-direction to opposite-direction mode. This parameter-based adaptation allows the interface to maintain simplicity while improving operational intuitiveness for different geometric configurations.
2Device complexity
If the relative angle between input unit and display unit is fixed at 360°, then the device structure is simplified, but the user experiences directional incongruity in the interface
Solution Approach 1:
Rather than fixing the relative angle at 360°, the patent introduces dynamic directional adjustment based on the actual relative angle. The determination unit evaluates the geometric relationship and adapts the output direction accordingly, maintaining structural simplicity while improving usability for the 360° configuration and other angles.
Solution Approach 2:
For configurations where the relative angle indicates opposite positioning (such as 360°), the patent inverts the output direction relationship. Instead of maintaining the same direction, the system uses opposite direction for the output, which resolves the directional incongruity experienced by users in these specific geometric configurations.
3Device complexity
If the output direction is always the same as input direction, then the interface design is simplified, but operational congruency deteriorates when relative position changes beyond 180°
Solution Approach 1:
The patent makes the output direction dynamic rather than static. The determination unit continuously evaluates the relative position and adjusts the output direction accordingly, ensuring operational congruency is maintained across different relative angles while keeping the interface design relatively simple.
Solution Approach 2:
The system changes the output direction parameter based on the relative position parameter. When the relative angle exceeds the threshold, the output direction is switched from same-direction to opposite-direction mode, maintaining operational reliability across varying geometric configurations without significantly complicating the interface design.
