Orientation-Adaptive Interactive Modules for Blind Device Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices with fixed UI modules require users to identify function keys differently based on their orientation, leading to reduced user experience due to the need for intentional operation adjustments.
Innovation Solution
A device operating method that establishes an adjustable instruction coordinate system aligned with the user's current orientation, allowing for blind operation by maintaining the interactive module's center position relative to the coordinate system, regardless of the user's orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the interactive module uses fixed-position function keys, then the device structure is simple, but the user experience deteriorates when users are positioned at different orientations
Solution Approach 1:
The patent applies the dynamics principle by making the coordinate system adjustable rather than fixed. The control unit dynamically adjusts the coordinate system of the interactive module based on the detected user orientation, allowing the function keys to be virtually repositioned according to the user's position. This resolves the contradiction by enabling adaptive operation ease without adding physical complexity to the device structure.
Solution Approach 2:
The patent implements parameter changes by modifying the coordinate system parameters (orientation angles, position coordinates) based on user orientation detection. When the user's position changes, the system changes the coordinate system parameters to maintain consistent operation paths, thereby improving ease of operation without altering the physical device structure.
2Adaptability or versatility
If the interactive module is adjusted to adapt to different user orientations, then the user experience is improved, but the device complexity increases due to additional sensors and processing
Solution Approach 1:
The patent applies universality by making the coordinate system adjustment mechanism serve multiple functions: it not only adapts to different user orientations but also maintains consistent operation paths and provides a unified control interface. This multi-functional approach allows the system to achieve high orientation adaptability without proportionally increasing device complexity, as the same mechanism handles multiple operational requirements.
Solution Approach 2:
The patent replaces potential mechanical adjustment mechanisms with an electronic/software-based coordinate system adjustment. Instead of physically moving or reconfiguring the interactive module hardware, the system uses software to transform coordinate systems based on sensor data, significantly reducing mechanical complexity while achieving the same adaptability goal.
3Measurement precision
If proximity sensors are added to detect user orientation, then the adaptability is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent uses proximity sensors as intermediary devices that detect user orientation without requiring direct mechanical interaction or complex integrated circuits. These sensors serve as mediators between the user's physical position and the digital coordinate system adjustment, providing accurate measurement while keeping the overall system manufacturable through the use of standard sensor components.
