  This work presents a smartwatch attached to patients at remote locations,
which would help in the navigation of wheel chair and monitor the vitals of
patients and relay it through IoT. This wearable smartwatch is equipped with
sensors to measure health parameters, namely, heartbeat, blood pressure, body
temperature, and step count. An esp8266 Wi-Fi module uploads the health
parameters into the thingspeak cloud platform with a time stamp. This
smartwatch is equipped with a joystick for cruise and navigation control of the
motor driver-enabled wheelchair. Additionally, an ultrasonic sensor mounted in
front of the wheelchair continuously scans for any obstacles ahead and stops
the motion of the wheelchair upon detection of an obstacle. The primary
controller of the system is an Arduino UNO microcontroller, which interfaces
the input and output modules.
