A Real–Time Intelligent Aid for Visually Impaired Safety and Emergency Response

Generally, most visually impaired people rely on a traditional white cane that onlydetects obstacles directly in front, leaving them completely unaware of surrounding hazardslike water puddles, pits, stairs and unexpected falls. Most existing smart aids improved basicnavigation but still fell short of delivering complete hazard protection. MAIRA1 — a Multisensing Assistive Intervention Real-time Awareness embedded aid — addresses these gaps bycontinuously monitoring the surroundings using multi-sensor technology for real-time hazarddetection. It accurately detects obstacles, water, pits, stairs and fall events, allows users totrigger an emergency through a simple shake gesture and locate the device with a double clap.In critical situations, MAIRA automatically sends the user's real-time GPS2 location via SMS3to a trusted contact. With clear voice alerts and reliable performance, MAIRA offers anaffordable and comprehensive solution for safer independent living.
