Wearable Display Positioning for User Activity Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable computing devices struggle to adapt their user interfaces effectively to different user activities, such as traveling upstairs or downstairs, leading to suboptimal display positioning and user interaction experiences.
Innovation Solution
An accelerometer system determines the user's activity and adjusts the user interface accordingly, shifting the display towards the top for traveling upstairs and towards the bottom for traveling downstairs, ensuring that computer-generated information remains in the user's line of sight and minimizing distractions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the display remains at a standard position on the display screen, then the user interface is simple and consistent, but the display information cannot remain in the user's line of sight when traveling upstairs or downstairs
Solution Approach 1:
The display positioning system dynamically adjusts the display position on the display screen based on real-time detection of user activity through the accelerometer system. When the user travels upstairs, the display shifts to the top portion; when traveling downstairs, it shifts to the bottom portion. This dynamic adaptation ensures the display remains in the user's line of sight while maintaining safety, resolving the contradiction between reliability and device complexity.
Solution Approach 2:
The accelerometer system continuously monitors user movement and provides feedback to the controller, which then adjusts the display position accordingly. This feedback loop ensures the display adapts to user activity patterns, maintaining information visibility without requiring complex manual intervention, thus improving safety while managing system complexity through automated response.
2Ease of operation
If the display is shifted to maintain information in the user's line of sight during activity changes, then user safety is improved, but the user interface becomes more complex
Solution Approach 1:
The user interface system automatically adjusts display positioning based on detected user activity without requiring manual user input. The accelerometer system and controller work together to self-regulate the display position, making the system easier to use while managing complexity through automated decision-making based on motion patterns.
Solution Approach 2:
The system changes the spatial parameter of the display position on the display screen based on detected user activity parameters. By mapping accelerometer data to specific display regions (top for upstairs, bottom for downstairs), the system simplifies user interaction while managing complexity through predefined parameter mappings rather than complex real-time calculations.
3Adaptability or versatility
If the user interface adapts to different user activities through display shifting, then usability is improved, but the system complexity increases
Solution Approach 1:
The accelerometer system serves multiple functions: detecting user activity types (upstairs, downstairs, walking, running) and triggering appropriate display positioning. This multi-functionality improves adaptability while managing complexity by using a single sensor system for both detection and control decisions, rather than requiring separate specialized systems for each function.
Solution Approach 2:
The system pre-establishes display positioning rules for different user activities before they occur. When accelerometer data matches predefined activity patterns, the corresponding display position is automatically activated. This preliminary configuration improves adaptability through prepared responses while reducing real-time computational complexity by using predefined mappings rather than complex on-the-fly calculations.
