Camera-Based Wearable Posture Guidance for Ergonomic Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable devices fail to effectively guide users into maintaining correct postures while interacting with external objects, leading to potential health issues such as forward head posture and text neck syndrome.
Innovation Solution
A wearable device equipped with sensors and cameras identifies the user's posture and external objects within its field of view, displaying visual objects to guide posture correction, utilizing haptic feedback for alignment, and adjusting display elements to maintain ergonomic viewing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the wearable device displays visual objects to guide posture correction, then the user experience is enhanced and ergonomic use is promoted, but the device complexity increases due to integration of sensors, cameras, and display systems
Solution Approach 1:
The patent combines multiple functional components (sensors, cameras, display systems, processors) into a single wearable device unit that integrates posture detection, image capture, and visual guidance functions, resolving the contradiction by merging separate systems into one cohesive device
Solution Approach 2:
The wearable device performs multiple functions simultaneously: detecting user posture through sensors, capturing images of external objects via camera, processing this data to determine viewing angles, and displaying visual objects for guidance - making the device universal and multi-functional to address various needs in one system
2Reliability
If the device continuously monitors and adjusts display based on posture, then ergonomic viewing is maintained, but the energy consumption increases
Solution Approach 1:
The device implements a feedback loop where sensors continuously monitor user posture, the processor analyzes this data to determine current viewing angle, and the display dynamically adjusts visual object positioning based on this feedback, maintaining ergonomic viewing while optimizing energy use through responsive rather than continuous full-power operation
Solution Approach 2:
The display system dynamically adjusts its behavior based on real-time posture detection, changing visual object positions and display parameters according to the user's current head and eye position rather than maintaining static high-power operation, thereby balancing ergonomic reliability with energy efficiency
3Adaptability or versatility
If the wearable device provides augmented reality services with multiple visual objects, then the user experience is enhanced, but the field-of-view management becomes complex
Solution Approach 1:
The processor determines specific viewing angles for different visual objects based on the detected head and eye positions, assigning different display parameters and positions to different visual objects according to their local requirements within the field of view, thereby managing complexity through localized optimization rather than uniform treatment
Solution Approach 2:
The device manages field-of-view complexity by adding spatial dimensionality to visual object placement, positioning multiple visual objects at different locations and angles within the three-dimensional field of view based on user posture, allowing versatile AR services while organizing complexity through spatial arrangement

AI summary
A wearable device according to an embodiment may acquire an image by means of a camera in a state where the wearable device is worn by a user. In the above state, the wearable device may identify the user's posture on the basis of data of a sensor. On the basis that the identified user's posture is a first designated posture, the wearable device may acquire a first visual object corresponding to an external object by means of the camera and display, within an FoV, a second visual object for guiding a change of the posture. On the basis of identifying that the user's posture is changed from the first designated posture to a second designated posture, the wearable device may display the acquired first visual object within a region including the center of the FoV.
