Head-Worn AR Proximity Warning for Safe Cycling Braking Distance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Riders of vehicles, such as bicycles, may be unaware of unsafe following distances, leading to potential collisions, as existing head-worn AR devices lack effective proximity warning systems to alert users of unsafe braking distances based on speed and environmental conditions.
Innovation Solution
A head-worn device equipped with cameras and processors that capture images, determine speed and distance to other objects, calculate braking distances considering user and environmental parameters, and provide visual or audible warnings when the distance becomes unsafe.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a head-worn AR device is used to provide augmented reality experience, then the user can view surrounding environment and virtual objects simultaneously, but the user becomes unaware of unsafe following distances and potential collision hazards
Solution Approach 1:
The system continuously monitors the user's speed and distance to other objects, then provides real-time feedback through proximity warnings when unsafe conditions are detected. This feedback loop maintains safety awareness while the user enjoys the augmented reality experience, resolving the contradiction between versatility and safety.
Solution Approach 2:
The head-worn device acts as an intermediary between the user and the environment, calculating braking distances and generating warning notifications that bridge the gap between the virtual augmented reality content and real-world safety hazards, allowing both experiences to coexist safely.
2Measurement precision
If the head-worn device calculates braking distance based on speed and environmental parameters, then accurate safety warnings can be provided, but the device complexity increases
Solution Approach 1:
The head-worn device leverages its existing multi-functional capabilities (camera for AR, sensors for motion tracking) to also perform braking distance calculations. By making the device universal and multi-functional, the patent avoids adding dedicated complex hardware while achieving precise safety measurements through software processing of existing sensor data.

AI summary
Disclosed is a method of providing a proximity warning using a head-worn device. A distance is determined between the head worn device and a relevant object, such as a cyclist, jogger or vehicle, using image-processing techniques. A speed of the head-worn device is determined using a GPS receiver or other position components located in the head-worn device or an associated user-device. A braking distance for the head-worn device is determined based on the speed of the head-worn device, and compared to the distance to the relevant object. A warning notification is provided by the head-worn device if the distance to the relevant object is less than the braking distance.
