Safe Walking Feedback Using Vehicle-Linked Obstacle Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies lack effective methods to provide real-time feedback for safe walking to users while they are moving in a vehicle, especially in situations where nearby obstacles are detected.
Innovation Solution
An electronic device equipped with a vision camera, sensor module, communication module, output module, memory, and processor is used to connect with a vehicle via short-range communication. This device determines an expected moving path, recognizes obstacles, and provides risk notifications to the user through the device or the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic device uses multiple sensors and communication modules to detect obstacles and provide real-time feedback, then user safety is improved, but device complexity increases
Solution Approach 1:
The system divides the safety monitoring function into two separate devices: the vehicle's ADAS system handles obstacle detection using vehicle-mounted sensors, while the user's electronic device handles feedback delivery through display, audio, or haptic components. This segmentation allows each device to specialize in its strengths without requiring the user's portable device to contain complex sensor arrays.
Solution Approach 2:
The electronic device acts as an intermediary between the vehicle's ADAS system and the user. It receives obstacle information from the vehicle via short-range communication, processes this data, and delivers appropriate feedback to the user. This intermediary role enables the user's simple portable device to provide safe walking support without needing complex sensing capabilities.
2Measurement precision
If the electronic device continuously monitors obstacles using vision camera and sensors, then collision detection accuracy is improved, but energy consumption increases
Solution Approach 1:
The vehicle's ADAS system performs preliminary obstacle detection and identification before the user approaches potential hazards. By pre-processing the environmental data and identifying obstacles in advance, the system reduces the need for continuous high-power sensing by the user's electronic device, as it only needs to receive and relay already-processed obstacle information.
Solution Approach 2:
The system replaces the need for continuous active sensing by the user's device with passive reception of obstacle data from the vehicle's ADAS system. Instead of the portable device continuously activating its vision camera and sensors, it relies on the vehicle's more powerful sensing system and communicates obstacle information through low-power wireless communication.

AI summary
A device is provided that includes a vision camera, a sensor module, a communication module, an output module, a memory, and a processor operatively connected to the vision camera, the sensor module, the communication module, the output module, and the memory. The processor is configured to connect to an external electronic device via the communication module, receive, from the external electronic device, location information of the external electronic device and determine an expected moving path, recognize an obstacle on the expected moving path based on at least one of the location information of the external electronic device, an image acquired from the vision camera, a sensor value acquired from the sensor module, and information collected from another device located on a road through the communication module, and determine risk of collision between the external electronic device and the obstacle so as to provide a risk notification through the output module.
