Display Device Break Reminder via Distance Estimation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Long-term computer usage leads to health issues such as computer vision syndrome and carpal tunnel syndrome due to prolonged screen viewing and typing, causing eye strain, fatigue, and physical discomfort, with existing solutions focusing on curing rather than preventing these conditions.
Innovation Solution
A display device equipped with a distance estimator, clock counter, and central processing unit that tracks user interaction and alerts the user to take breaks after a predetermined time of use, prompting rest to prevent fatigue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If users continuously use the display device for long periods, then productivity increases, but user fatigue and health problems worsen
Solution Approach 1:
The system continuously monitors usage time through the clock counter and provides feedback to the user via display prompts when predetermined time thresholds are reached. This feedback mechanism alerts users to take breaks, creating a closed-loop system that prevents fatigue accumulation while maintaining productive usage patterns.
Solution Approach 2:
The system proactively alerts users before fatigue sets in by monitoring usage time and issuing break reminders at predetermined intervals. This preliminary action prevents the development of fatigue and health problems rather than addressing them after they occur, aligning with the preventive health approach.
2Object-affected harmful factors
If users take regular breaks to prevent fatigue, then health conditions improve, but productivity decreases
Solution Approach 1:
The system implements periodic break reminders at predetermined time intervals during usage. This creates a rhythm of work and rest that prevents continuous fatigue accumulation while maintaining overall productivity through sustainable usage patterns. The periodic nature of the reminders ensures breaks are taken regularly without completely interrupting workflow.
3Measurement precision
If the display device monitors user presence and tracks time, then break reminder accuracy improves, but device complexity increases
Solution Approach 1:
The display device integrates multiple functions into existing components: the display unit serves both as the output interface and the monitoring indicator, the clock counter provides both timing functionality and usage tracking data, and the processor handles both general operations and break reminder logic. This multi-functionality reduces the need for separate dedicated components, thereby limiting the increase in device complexity.

AI summary
The present invention provides method for break reminder and a display device. The display device includes a display unit; a clock counter; a distance estimator configured for detecting if the display device being used by a user, calculating distance between the user and a front of the display device, and generating a tracking signal if the distance is less than a predetermined distance; and a central processing unit configured for waiting for the tracking signal, resetting a worked time and a rested time when the tracking signal is received, signaling the clock counter to track the worked time, detecting if the worked time is less than a first predetermined time, and signaling the display unit to output the message prompt when the worked time is equal to or greater than the first predetermined time, thereby the present invention can prevent the user of the display device from fatigue.
