Segmented Head-Mount Sensor Mounting Tool for Natural Motion Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for sensing the position or orientation of the head in a natural state are hindered by the need for large, helmet-shaped wearable devices that impair both the wearing feeling and appearance.
Innovation Solution
A mounting tool comprising a frontal region fixing unit, an occipital region fixing unit, and a sensor device fixing unit that securely attaches a sensor device to the rear surface of the occipital region fixing unit, allowing for accurate detection of head position and orientation without compromising comfort or aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a helmet-shaped wearable device is used to sense head position and orientation, then sensing capability is achieved, but wearing comfort and appearance are impaired
Solution Approach 1:
The wearable device is segmented into multiple independent fixing units: a frontal region fixing unit, an occipital region fixing unit, and a sensor device fixing unit. This segmentation allows the device to be distributed across different head regions rather than requiring a single large helmet structure, thereby improving wearing comfort while maintaining sensing capability.
Solution Approach 2:
The sensor device is extracted and mounted separately on the occipital region fixing unit, which is positioned on the rear surface of the occipital region. This extraction allows the sensing function to be achieved without requiring a full helmet structure, reducing the overall bulk and improving both comfort and appearance.
2Measurement precision
If a helmet-shaped wearable device is used to sense head position and orientation, then sensing capability is achieved, but appearance becomes strange and unstylish
Solution Approach 1:
The device is divided into separate fixing units positioned at different locations on the head (frontal and occipital regions). This segmentation eliminates the need for a continuous helmet structure, resulting in a more aesthetically pleasing appearance that does not look strange or bulky.
Solution Approach 2:
The sensor device is extracted from the main body structure and mounted separately on the occipital region fixing unit. This extraction allows the sensing functionality to be achieved with minimal visual impact on appearance, making the device more stylish and acceptable for normal use.
3Measurement precision
If a large-scale wearable device is used, then sensing capability is achieved, but the device becomes cumbersome and unnatural for daily use
Solution Approach 1:
The wearable device is segmented into multiple small, distributed fixing units rather than a single large structure. This segmentation significantly reduces the overall weight and bulk of the device, making it suitable for natural, daily use while maintaining the necessary sensing capability through the distributed sensor arrangement.
