    Quadriplegic patient assistive system for requirement sharing and home appliance control using 3-axis accelerometer with IoT
    (International Islamic University Chittagong, 2022-12) Alam, Md. Eftekhar
    This research article aims to develop a device that can help paraplegic patients who can only move their heads. Previously, head movement techniques were used to control wheelchair movements. The proposed device uses head movements to control appliances (lights, fans, etc.) and indicates the patient's different needs (water, food, etc.). In this system, a 3-axis accelerometer detects the movement of the paralyzed patient's head and sends it to a microcontroller. The microcontroller converts this signal and sends this to the second microcontroller via the Bluetooth module. The converted signal passes through a dot-matrix display that displays an image of each requirement. At the same time, the caretaker will be notified by a buzzer. In addition, the patient can control the appliances without outside help. In testing, the system shows superior accuracy when controlling appliances compared to LCD displays for special requirements. In the test run, the prototype shows the layout of head movement and detection of special needs.
