Innovative Speaker System for Communication in Patients with Cerebral Palsy

This capstone project presents a speaker system designed for individuals with spastic cerebral palsy, specifically targeting non-verbal users like Ken (Pooch), who attends a day program in Massachusetts. The system aims to provide a personalized communication solution that is user-friendly, portable, and durable for use in various caregiving scenarios, including beds and wheelchairs. Key features include a customizable switch panel, LCD display, and a long-lasting rechargeable battery. The device will empower users by enabling them to express themselves effectively and improve their quality of life.
