The Directional Audio CAPTCHA for the Visually Impaired uses head movement detection through Arduino sensors to verify users, enhancing security and accessibility without requiring expensive hardware. This system offers significant economic and practical benefits, improving website security and user experience while supporting the development of biometric authentication technologies.

The Portable Braille Converter translates photographed text into Braille and speech, using solenoids to display Braille dots and a smartphone app for text recognition and conversion. This versatile device offers significant economic benefits by allowing existing signs to be used without modification and alleviates the burden of mandatory Braille signage for the visually impaired and general public.

The Automated Acoustic Signal Device uses Arduino to provide location information and street details automatically to visually impaired users within a certain range, eliminating the need for manual button pressing and allowing flexible installation locations. It enhances hygiene and safety by operating without physical contact and automatically detecting nearby signals, offering significant improvements over traditional systems.

This invention uses Arduino and smartphones to help people with color blindness easily identify colors, displaying information via earphones and an LCD screen. It focuses on training color differentiation through a user-friendly application and portable sensor, making it practical for everyday use and significantly cheaper than existing correction products.

AccessZone Tracker is a mobile app providing real-time information on disabled parking spaces, including location, availability, and fees, with a user-friendly map interface and detailed filtering options. It offers additional information on fee reductions and facility accessibility, making it easier for individuals with mobility impairments to find and use parking spaces.

This innovative device, attachable to a wheelchair, sends assistance requests to nearby staff in places like subways and hospitals. It is cost-effective at under 4,000 KRW and offers a signal range of up to 1 km. This ensures prompt help and prevents wheelchair accidents.

The Automated Tray Collection Robot improves nursing staff treatment by ensuring their meal and break times, significantly reducing their workload without additional hardware costs. This innovation promises substantial economic benefits by saving approximately $30.2 billion annually in nursing labor costs and addresses nurse retention issues caused by excessive workloads.

The Hand Gesture Recognition Wheelchair with Mecanum Wheels enhances maneuverability and safety for users by allowing omnidirectional movement and recognizing hand gestures for autonomous navigation. This innovation aims to improve the mobility, working conditions, and wages of disabled individuals while reducing shoulder injuries and related medical costs.

The Smart Home for the Visually Impaired includes features for temperature control, earthquake detection, and bathroom entry detection, providing auditory notifications to enhance safety and convenience. It is cost-effective and enhances the daily lives of visually impaired individuals by automating essential home functions and increasing their psychological comfort.

The Voice-Assisted Kiosk Program enhances existing kiosks with a cost-effective software update, enabling visually impaired users to navigate through voice prompts without needing additional staff or expensive hardware changes. It uses the Levenshtein distance algorithm to ensure accurate order placement, offering a seamless and inclusive experience for users with disabilities.

The Smart Shelter Chair uses discarded coffee grounds and features cooling and heating functions activated by a pressure sensor, with a cane equipped with a heart rate sensor to display heart rate on a screen. This eco-friendly, energy-efficient chair provides convenient resting places for the elderly and disabled, enhancing safety and comfort in public spaces.
