Abstract— This paper describes how the hand motions of semi-paralysed individuals will be utilised to communicate. The user must attach his or her hand to the device. In order to transmit a message, the user must tilt the device at a precise angle. A new message is transmitted by rotating the device in a different direction.

This technology utilises an accelerometer to detect motion. The data is then transmitted to the Arduino Atmega microcontroller. The patient motion recorder’s data signal is transmitted using an R.F. transmitter. In contrast, an R.F. receiver receives and decodes the data before giving it to the Arduino, which analyses the input and displays the message accordingly. The accompanying message is now displayed on the LCD screen of the Arduino. It emits a beeping sound and communicates a message when the accelerometer detects motion.
