Solution Overview

Problem

Mobile devices struggle to maintain readable graphic user interfaces when inclined relative to a user's gaze, leading to reduced icon and notification window sizes, making it difficult for users to interact with them without adjusting their posture or picking up the device.

Innovation Solution

A mobile device equipped with a sensor to detect the user's eye position and a relative inclination calculator, along with a graphic user interface magnification processor, which adjusts the size and position of pre-designated graphic user interfaces based on the inclination, ensuring they remain readable and interactable even when the device is inclined.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the mobile device is placed at a considerable inclination from the user's gaze, then the device can be used in various positions (e.g., on a table during a meeting), but the graphic user interface shrinks in the direction of the user's gaze, making it difficult to read and interact with

Engineering Contradiction:

Improvedevice positioning flexibilityVSAvoidGUI readability and interactability

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent implements dynamic magnification of the graphic user interface based on the detected inclination angle. The system continuously monitors the device's orientation and adjusts the magnification level in real-time, transforming the static display into a dynamic adaptive interface that responds to changing viewing conditions.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the display parameter (magnification level) based on the inclination angle parameter. By establishing a relationship between these two parameters, the system automatically adjusts the GUI size to compensate for the perspective distortion caused by inclined viewing, thereby maintaining readability across different device positions.

Inventive Principle:

Principle #35Parameter changes

2Ease of operation

If the user picks up the mobile device to read the graphic user interface clearly, then the interface remains at normal size, but the user cannot maintain a comfortable posture during prolonged use

Engineering Contradiction:

ImproveGUI readabilityVSAvoiduser posture adjustment requirement

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system performs self-adjustment by automatically detecting its own inclination state and applying the appropriate magnification correction. This eliminates the need for user intervention or manual posture adjustment, as the device serves itself by adapting the display to its current orientation.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical solution of physically lifting the device with a software-based magnification system. Instead of requiring mechanical movement (picking up the device), the system uses digital image processing and display parameter adjustment to achieve the same goal of improving readability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If the graphic user interface is magnified to compensate for inclination, then readability is maintained, but other elements on the display may become crowded or overlap

Engineering Contradiction:

ImproveGUI readabilityVSAvoiddisplay layout arrangement

Core Design Contradiction:

Ease of operationVSShape

Solution Approach 1:

The system applies magnification selectively to specific regions of the display rather than uniformly across the entire screen. By identifying the relevant GUI elements and magnifying only those areas, the system maintains readability while preserving the overall display layout and avoiding unnecessary crowding of other elements.

Inventive Principle:

Principle #3Local quality
