Wearable Vibration Guidance for Visually Impaired Swimmers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Visually impaired swimmers face challenges in navigating swimming pools and open water due to lack of accurate guidance, leading to increased race times, safety risks, and inefficient swimming techniques, as existing solutions like GPS and visual aids are inadequate for indoor environments and fail to provide the necessary precision.
Innovation Solution
A system comprising a destination device and directional guidance equipment worn by the swimmer, utilizing vibration hardware to dynamically indicate the direction to swim, which includes directional determination means using technologies like GPS, RF, and sonar for accurate positioning and guidance, allowing the swimmer to maintain a straight course without relying on visual cues or physical tethers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If GPS tracking is used for guidance, then the swimmer can be guided in open water environments, but the GPS signal is blocked by buildings in indoor environments and accuracy is insufficient
Solution Approach 1:
The system combines multiple positioning technologies (GPS, RF, sonar) into a single integrated guidance system that can operate in both indoor and outdoor environments. The directional guidance equipment processes signals from different sources to provide continuous accurate positioning regardless of the environment, making the system universally applicable to various swimming conditions.
Solution Approach 2:
The system dynamically switches between different positioning methods based on environmental conditions. When GPS signals are unavailable (indoor environments), the system transitions to using RF signals or sonar data, changing the operational parameters of the positioning system to maintain accuracy across different settings.
2Reliability
If a tapper is used to signal the swimmer, then the swimmer can be alerted to the pool end, but incorrect timing affects flip turn efficiency and increases race time
Solution Approach 1:
The directional guidance equipment continuously monitors the swimmer's position relative to the pool end and provides real-time feedback through vibration patterns. The system detects when the swimmer is approaching the pool end and adjusts the vibration signal to prompt timely preparation for the flip turn, ensuring optimal timing based on actual swimmer position rather than fixed intervals.
Solution Approach 2:
The guidance device uses vibration hardware that emits detectable vibration patterns on the swimmer's body. Different vibration patterns indicate different states (e.g., approaching pool end, ready for turn), providing tactile feedback that enables precise timing for flip turns without visual cues.
3Ease of operation
If a physically tied guide swimmer is used, then the visually impaired swimmer can be guided along the route, but it is cumbersome and creates safety hazards
Solution Approach 1:
The system replaces the mechanical tethering arrangement with an electronic guidance system. Instead of being physically connected to a guide swimmer, the visually impaired swimmer wears a guidance device that wirelessly receives directional information from destination devices, eliminating the physical constraints and safety risks associated with being tied to another person.
Solution Approach 2:
The guidance system enables the visually impaired swimmer to navigate independently without requiring a physical guide. The directional guidance equipment processes positioning data and provides autonomous directional instructions through vibrations, allowing the swimmer to self-navigate the course without external human assistance.
4Adaptability or versatility
If visual aids like LED lighting are used, then non-visually impaired swimmers can stay on course, but such aids are ineffective for visually impaired swimmers
Solution Approach 1:
The guidance device uses vibration hardware that emits detectable vibration patterns on the swimmer's body. Different vibration patterns indicate different states (e.g., approaching pool end, ready for turn), providing tactile feedback that enables precise timing for flip turns without visual cues.
