Individuals affected by speech disorders or severe muscular weakness often face significant communication barriers. Children and adults unable to speak rely on gestures or Augmentative and Alternative Communication (AAC) tools to express their needs. This project proposes the development of an advanced AAC device designed to assist partially paralyzed or speech-impaired patients. The system captures gestures from active body parts using sensors such as accelerometers, flex sensors, and force sensitive resistors (FSR) to interpret intended communication. These sensors generate analog signals corresponding to physical movements, which are processed and translated into meaningful output. Integrating IoT technology enables real-time monitoring and doctor–patient interaction, enhancing healthcare accessibility. Psychologically, this device promotes independence and confidence among patients by enabling self-expression without constant caregiver assistance.
