Posture Assistance Device Using Dynamic Display Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing posture improvement devices lack motivation for users to maintain proper posture, as simple notification sounds or posture models do not effectively encourage users to correct their posture.
Innovation Solution
A posture improvement assistance device that dynamically adjusts the display or audio output conditions, such as position, size, shape, and volume, to create discomfort when the user's posture deviates from the proper posture, motivating them to correct it.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a notification sound is issued when posture is incorrect, then the user is notified of the posture deviation, but the user lacks motivation to improve posture
Solution Approach 1:
The system implements feedback by dynamically adjusting display or audio output based on detected posture. When incorrect posture is detected, the display position, size, or audio output is changed, providing continuous feedback that motivates the user to correct their posture to restore the original display/audio state.
Solution Approach 2:
The system changes display parameters (position, size, shape) or audio output parameters (volume, channel balance) in response to posture detection results. These parameter changes create a dynamic interaction where the user must adjust their posture to restore the reference state, thereby providing motivation.
2Loss of information
If a posture model is displayed to show user movement, then the user becomes aware of their posture, but the user lacks motivation to improve posture
Solution Approach 1:
Instead of merely displaying a posture model, the system provides feedback by changing display or audio output conditions based on posture detection. This creates a cause-effect relationship where posture correction directly influences the display/audio state, providing continuous motivation.
Solution Approach 2:
The system inverts the conventional approach by not directly showing posture information but instead modifying the user's interaction with the device (display position, audio output) based on posture. The user infers their posture state from these modifications and adjusts accordingly.
3Ease of operation
If display position is changed from reference position when posture is incorrect, then the user experiences discomfort, but the system complexity increases
Solution Approach 1:
The system uses the user's own device (display or audio output) to provide the corrective feedback. The device itself serves the dual purpose of being both the tool the user interacts with and the medium through which posture feedback is delivered, reducing the need for additional specialized components.

AI summary
The present invention provides a posture improvement assistance device, a posture improvement assistance method, and a non-transitory storage medium storing a posture improvement assistance program that give a user a strong motivation to improve one's posture and assist in achieving a good posture. A control unit of an electronic device includes a posture acquisition unit (21A) that acquires information on a posture of a user who is using a display unit; and a display control unit that, when the posture satisfies a condition, controls a display condition of an image displayed on the display unit to be in a reference state, and when the posture does not satisfy the condition, controls the display condition to be in a state that is changed with respect to the reference state.
