Environment-Level Wearable Display for Obstacle Collision Warnings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable devices lack the capability to effectively assess environmental danger levels and provide obstacle-related information to users, particularly in augmented or virtual reality environments, thereby failing to adequately warn users of potential collisions.
Innovation Solution
A wearable electronic device equipped with a camera, microphone, sensor, and processor that determines environment levels, decides which sensors to use, obtains obstacle information and estimated impulses, and generates a user interface to display collision danger, providing graphic entities on a display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensors (camera, microphone, sensor) are used to obtain obstacle information and estimated impulse, then the accuracy of collision warning is improved, but the device complexity increases
Solution Approach 1:
The system segments the sensing function by selecting specific sensors (camera, microphone, or sensor) based on the determined environment level. This allows the system to use only the necessary sensors for each situation, improving accuracy when needed while avoiding the complexity of always using all sensors.
Solution Approach 2:
The device dynamically determines which sensors to use based on the environment level. The controller selectively activates sensors according to the determined environment level, optimizing the balance between measurement precision and device complexity for each operational context.
2Ease of operation
If the system determines environment level and selectively uses sensors based on that level, then the appropriate information is provided to users, but the system complexity increases
Solution Approach 1:
The system performs preliminary determination of the environment level before obtaining obstacle information. This preliminary assessment guides subsequent sensor selection and information processing, ensuring appropriate information is provided while managing system complexity through structured decision flow.
Solution Approach 2:
The system changes operational parameters (sensor selection, information processing depth) based on the determined environment level. This parameter adaptation allows the system to provide appropriate information for each environment while managing complexity through conditional parameter adjustment rather than always operating at maximum capacity.
