Wireless Assistive Communication Using Head Gestures and Voice Alerts for Paralyzed Patients

Abstract: The development of innovative communication systems for individuals with severe mobility impairments has made significant progress. This wireless system uses head movement detection, powered by ESP-32 accelerometers, to capture subtle gestures and translate them into predefined commands. These commands are transmitted wirelessly to a receiver, activating a speech alert system that allows effective communication. This solution greatly enhances the quality of life for individuals with paralysis by offering a reliable, intuitive, and non-invasive means of interaction. It reduces dependence on caregivers and promotes greater independence. Beyond communication, the system can also be adapted for home automation, making it a versatile tool for daily living. Designed to meet the critical needs of users with conditions such as ALS, spinal cord injuries, or strokes, the system fills a crucial gap in assistive technology. Its user-friendly, cost-effective design empowers users to express themselves, make decisions, and interact meaningfully with others. Ultimately, this system not only meets a practical need but also advances the field of assistive technology by restoring dignity and autonomy to those with disabilities.
