Wearable Display Content Management for Fatigue Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices such as smart glasses can cause user fatigue and eye strain due to prolonged content viewing, with existing solutions failing to effectively address these issues.
Innovation Solution
A wearable device equipped with a display, audio output, and communication units that monitor usage time, battery consumption, and temperature, and provides guide information to users to stop content reproduction and switch to different content, using a processor to manage content output and request signals between external devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If content is reproduced continuously through the display, then productivity of content consumption is improved, but user fatigue and eye strain increase
Solution Approach 1:
The system implements periodic display activation synchronized with the user's walking or running pace. The display turns on and off in rhythm with the user's movement, providing content during active periods while allowing rest during other phases. This periodic operation maintains content consumption productivity while preventing continuous eye strain and fatigue by introducing regular breaks in the display output.
2Object-affected harmful factors
If the display is turned off frequently to prevent fatigue, then user health is protected, but productivity of content consumption decreases
Solution Approach 1:
The display operates in periodic cycles synchronized with user activity, turning on during walking/running phases when content consumption is desired and turning off during rest phases to prevent eye strain. This approach protects user health while maintaining acceptable content consumption productivity by utilizing the natural rhythm of physical activity.
Solution Approach 2:
The system monitors user activity state (walking, running, or stationary) and uses this feedback to dynamically control display operation. When motion is detected, the display activates for content consumption; when motion stops, the display deactivates to prevent fatigue. This feedback mechanism ensures the display operates only when beneficial, balancing health protection with productivity.
3Adaptability or versatility
If multiple external devices are connected for content reproduction, then adaptability of the wearable device is improved, but device complexity increases
Solution Approach 1:
The wearable device incorporates a universal communication interface that can connect to multiple types of external devices (smartphones, tablets, media players) through a single communication unit. This multi-functional capability allows the device to adapt to various content sources without requiring separate hardware for each device type, thereby improving adaptability while avoiding the complexity of multiple specialized connection systems.
Solution Approach 2:
The wearable device acts as an intermediary between the user and multiple external content devices. It receives content from any connected external device, processes it, and outputs through the display and audio unit. This intermediary role simplifies the system architecture by providing a single point of contact for multiple content sources, reducing overall system complexity while maintaining high adaptability.
