GESTURE BASED CALLING SYSTEM

The interaction between a nurse and patient depends majorly on the communication medium. The augmentation of the Internet of Things (IoT) in the recent era allows us to accommodate this technology in various aspects of our lives to make the process secure and reliable. We are using the knowledge of IoT for making this interaction system secure and easy to use. By introducing hand gestures for calling the attendee makes this device convenient to operate by the differently abled people. From this perspective, this paper presents a real-time nurse calling system based on the performed hand movements. Further, the gesture is detected by the accelerometer and processed by the micro controller. The corresponding message is sent to the attender's smartphone, and the nurse responds at the earliest. The device uses low-cost components such as Raspberry Pi, accelerometer and a heartbeat sensor.
