Design of an automated healthcare system using hand gestures for paraplegic people

Paralyzed individuals often struggle to express their needs due to a lack of motor control in the brain, leading to difficulties in speech or sign language communication. The proposed system offers a solution for disabled individuals to communicate by displaying messages on a monitor through simple hand movements. The device uses an accelerometer to detect various hand tilt directions, allowing the user to convey different messages by tilting the device in different directions. The accelerometer measures the motion statistics and sends the information to the microcontroller for processing. Once processed, the appropriate message is displayed and a buzzer sounds. If the message is a call for assistance, the IFTTT app is activated and a message is sent to the doctor’s phone. This system enables paralyzed patients to effectively communicate their basic needs.
