Wearable Posture Guidance Using Field-of-View Visual Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable devices lack the capability to guide users into maintaining a correct posture while interacting with external objects, which can lead to discomfort and health issues such as forward head posture or text neck syndrome.
Innovation Solution
A wearable device equipped with sensors, a camera, and a display that identifies the user's posture and displays visual objects to guide adjustments, ensuring the user maintains a correct posture while viewing external objects within the field-of-view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wearable device displays visual information to users, then the user experience is enhanced, but the user may develop incorrect posture such as forward head posture or text neck syndrome
Solution Approach 1:
The wearable device continuously monitors the user's posture using sensors (accelerometer, gyro sensor) and provides real-time feedback through visual cues displayed in the user's field of view. When incorrect posture is detected, the device displays guidance information to guide the user back to correct posture, creating a closed-loop feedback system that prevents long-term posture damage while maintaining enhanced user experience
Solution Approach 2:
The device proactively detects posture deviations before they become problematic and displays preventive guidance information. By identifying incorrect posture early and providing immediate visual feedback, the system prevents the development of forward head posture and text neck syndrome before they cause harm, rather than waiting for symptoms to appear
2Reliability
If the wearable device provides continuous posture guidance, then posture correction is achieved, but the device complexity increases
Solution Approach 1:
The wearable device integrates multiple functions into a single platform: it serves as both an AR display device for providing visual information and a posture monitoring device. The same sensors, processor, and display components used for general AR functionality are leveraged for posture detection and guidance, eliminating the need for separate dedicated posture correction hardware and reducing overall device complexity
Solution Approach 2:
The device uses its own existing sensors and processing capabilities to monitor and correct its user's posture, rather than requiring external monitoring equipment. The integrated sensor suite (accelerometer, gyro sensor) and processor enable the device to autonomously detect posture, analyze deviations, and provide appropriate feedback without external intervention, simplifying the system architecture

AI summary
A wearable device is provided. The wearable device includes a sensor, a camera, a display, memory storing one or more computer programs, and one or more processors communicatively coupled to the sensor, the camera, the display, and the memory, wherein the one or more computer programs include computer-executable instructions that, when executed by the one or more processors individually or collectively, cause the wearable device to obtain, in a state that the wearable device is worn by a user, an image using the camera, in the state, identify a posture of the user based on data of the sensor, based on identifying the posture of the user, which is a first preset posture, obtain a first visual object corresponding to an external object using the camera, and display a second visual object for guiding changing of the posture within a field-of-view (FoV), based on identifying that the posture of the user is changed from the first preset posture to a second preset posture, display the obtained first visual object in an area including a center of the FoV.
