Wearable Display Axis Mapping for Orientation Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices face challenges in providing and receiving user input effectively due to varying orientations caused by movement, which complicates the mapping of user inputs to device axes.
Innovation Solution
A system and method where a computer determines and updates user-defined axes based on angular movement data and rotation speed, allowing user inputs to be mapped across different orientations, enabling continuous input reception without requiring the device to maintain a fixed orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the wearable device operates with fixed device axes, then the input mapping is simple, but the device cannot accommodate varying orientations during movement
Solution Approach 1:
The patent applies dynamics by making the input mapping adaptive rather than fixed. The system dynamically adjusts the mapping between device axes and display axes based on detected orientation changes. When the wearable device rotates or changes orientation, the processor detects this change and recalculates the coordinate transformation, allowing the interface to adapt seamlessly to different wearing positions without requiring fixed device orientation.
Solution Approach 2:
The patent changes the mapping parameters (rotation angles, axis orientations) based on detected device orientation. By monitoring orientation sensors and adjusting the coordinate transformation parameters in real-time, the system accommodates varying device orientations while maintaining consistent user interaction. This parameter adaptation resolves the contradiction between simplicity and adaptability.
2Measurement precision
If the device axes are fixed relative to the display, then the manufacturing is simple, but the user input mapping becomes inaccurate during device rotation
Solution Approach 1:
The patent implements feedback by continuously monitoring device orientation through sensors and using this information to adjust the input mapping. The system detects orientation changes, calculates the appropriate coordinate transformation, and applies this transformation to maintain accurate input mapping. This closed-loop feedback mechanism ensures precise input recognition regardless of device rotation or orientation changes.
Solution Approach 2:
The patent performs preliminary axis determination by establishing the relationship between device axes and display axes before user input is received. By pre-calculating the transformation based on current orientation and updating this mapping as orientation changes, the system ensures accurate input interpretation without requiring complex real-time calculations during the actual input event.
3Ease of operation
If the wearable device allows free movement, then the usability is improved, but the coordinate mapping between device and display axes becomes inconsistent
Solution Approach 1:
The patent applies dynamics by making the coordinate mapping adaptive rather than fixed. The system dynamically adjusts the mapping between device axes and display axes based on detected orientation changes. When the wearable device rotates or changes orientation, the processor detects this change and recalculates the coordinate transformation, allowing the interface to adapt seamlessly to different wearing positions without requiring fixed device orientation.

AI summary
A first horizontal axis of a plane of a display is determined based on a user input. Angular movement data of the display is collected. A second horizontal axis of the plane of the display is determined based on the angular movement data. A second user input on the display is mapped based on the second horizontal axis.
