1. What will it do?
AquaVision is a wearable, waterproof device integrated into the head and body for people with visual disabilities. While underwater, the device will enable swimmers to:
1) Provide safety alerts for pool edge proximity
2) Have position information about the swimlanes and possible deviations
1) Provide safety alerts for pool edge proximity
2) Have position information about the swimlanes and possible deviations
The system monitors the swimmer's position within the swim lane and detects lateral deviations. When the user approaches the lane limits, the system generates a sound alert to indicate the correct direction.
2. Who has done what beforehand?
Traditional approach without focus on persons with visual disabilities. The underwater wearable has been partially explored by commercial and research efforts https://www.youtube.com/shorts/jiaPNjImB5M https://www.youtube.com/shorts/x-8rlnioR2I:
