User Device Context Switching for Eye Fatigue Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional user devices fail to provide suitable display solutions when a user is in an unsuitable context for reading, such as in a moving vehicle, leading to eye fatigue or long-term damage, as they cannot adapt their information providing mode to the user's current context.
Innovation Solution
A method and device that collect user context information, identify the current context, and switch the information providing mode accordingly, using modules like user context information collecting, context identifying, and mode switching to adjust display settings, such as switching between image and audio modes based on vibration or stability, to ensure comfortable information access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the user continues reading documentary information on a conventional user device in a moving vehicle, then the user can obtain new information, but the user's eyes will become fatigued or damaged long-term
Solution Approach 1:
The patent applies dynamics by making the information providing mode changeable based on user context. The system dynamically switches between different modes (e.g., visual display mode and audio output mode) according to the detected user state, such as whether the user is in a moving vehicle or in a stable environment. This allows the system to adapt to changing conditions and provide information in the most suitable way, preventing eye fatigue while maintaining information acquisition.
Solution Approach 2:
The patent changes the parameter of information providing mode based on user context detection. By detecting parameters such as device movement, user activity level, or environmental conditions, the system adjusts the information delivery parameters - switching from visual to audio modes or adjusting display characteristics. This parameter change enables continuous information acquisition without straining the user's eyes in unsuitable reading contexts.
2Object-affected harmful factors
If the user quits reading to prevent eye fatigue, then the user's eyes remain healthy, but the user loses the opportunity to obtain new information
Solution Approach 1:
The patent introduces an intermediary - an audio output module - that mediates between the visual information and the user's needs. When the system detects that the user is in a context unsuitable for reading (such as being in a moving vehicle), it activates the audio module to provide information verbally. This intermediary allows the user to continue acquiring information without using their eyes, thus maintaining eye health while preserving information acquisition productivity.
3Device complexity
If a conventional user device provides fixed display functions, then the device structure remains simple, but the device cannot adapt to different user contexts and reading conditions
Solution Approach 1:
The patent applies universality by enabling the user device to perform multiple information providing functions - both visual display and audio output - within a single device. The system includes a detection module that identifies user context, a switching module that selects the appropriate mode, and an audio module that complements the display module. This multi-functionality allows the device to adapt to various user contexts (reading, commuting, etc.) without requiring separate devices, thereby enhancing versatility while maintaining reasonable structural complexity.

AI summary
A method for switching a current information providing mode is provided, wherein the method comprises steps as follows: user context information related to a user device is firstly collected. A current user context of the user device is then identified in accordance with the collected user context information, so as to an identified consequence data is the generated. A current information providing mode suitable for the current user context of the user device is subsequently switched according to the consequence data.
