Vehicle Eye-Training Display With Feedback for Posture Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prolonged sitting and constant use of mobile devices lead to muscular tension, particularly in the back, neck, and eyes, affecting ocular health and overall well-being of vehicle occupants.
Innovation Solution
A method involving eye training exercises using a display unit, camera, and massage unit to relax eye muscles, improve posture, and stimulate metabolism, combined with breathing and neck movements, guided by visual, acoustic, and haptic feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If eye training exercises are implemented during vehicle breaks, then eye muscle relaxation and metabolic stimulation are achieved, but device complexity increases due to integration of camera, display unit, and massage unit
Solution Approach 1:
The patent combines multiple functions (eye tracking, display, and massage) into an integrated system. The control unit coordinates the camera for tracking eye movements, the display unit for presenting visual stimuli, and the massage unit for providing tactile feedback, thereby achieving eye training while reducing overall system complexity through unified control.
Solution Approach 2:
The system performs multiple functions simultaneously: the camera serves both for monitoring and eye tracking, the display unit provides both visual stimulation and feedback, and the massage unit delivers both relaxation and performance feedback. This multi-functionality reduces the need for separate dedicated components.
2Manufacturing precision
If the occupant focuses intensely on tracking visual stimuli, then eye training effectiveness increases, but breathing may stop or falter reducing overall health benefits
Solution Approach 1:
The system continuously monitors breathing patterns and provides real-time feedback through the display unit and acoustic output. When breathing irregularities are detected, the system alerts the occupant and can adjust the visual stimulus presentation to reduce concentration demands, thereby maintaining both tracking precision and breathing safety.
Solution Approach 2:
The system uses moderate visual stimuli that provide sufficient challenge for eye training without excessive concentration demands. The difficulty level is dynamically adjusted based on performance and physiological state, ensuring effective training while preventing breathing cessation.
3Measurement precision
If visual stimuli are presented at high contrast and sharp edges, then eye training effectiveness improves, but metabolic demand and muscular tension may increase
Solution Approach 1:
The visual stimuli are presented in periodic cycles with varying contrast levels and complexity. High-contrast sharp-edged stimuli are alternated with softer, less demanding patterns, allowing eye muscles to train effectively while periodic relaxation phases reduce cumulative metabolic demand and muscular tension.
Data Source
AI summary
Eyes of an occupant in a vehicle are trained by recording a head position and/or an eye movement of the occupant, displaying lines and/or dots are displayed on a display unit, asking the occupant to track a course of the lines by head movement or by eye movement, and outputting feedback on a respectively recorded head position and/or eye movement of the occupant.
