Wearable Computer With Temperature and Lidar Sensing

The document describes a wearable computer developed using a Raspberry Pi controller integrated with a touch screen display, temperature sensor, and lidar sensor mounted on a wrist strap. The wearable computer allows users to access computing power, measure temperature contactlessly, and measure distances using lidar anywhere. It runs a Linux operating system on the Raspberry Pi to enable file storage, browsing, and using tools from the wrist. Temperature and distance measurements are displayed live on the touch screen.

Wearable Computer with Temperature and Lidar Sensing

Computers have grown to be a vital part of human ecosystem. Mobile phones have also
evolved to provide increased computing power and applications over time. Also we have a
generation of smart watch era with watches evolving to show fitness data and other details
along with time.
Well we hereby take smart watches to the next level by developing a smart watch that is lit-
erally a wearable computer. A touch screen based computer that is not at your home, not in
your pocket but right on your wrist. It also has an integrated contactless temperature sensor
for measuring anyone’s temperature anytime. Also we add a contactless lidar distance sensor
to it which also allows user to measure anything anywhere.
The wearable computer provides following features:
 Ability to get the power of a personal computer right on your hand
 Touch display for easy interaction
 Internet connectivity on Smart watch
 Ability to google search from anywhere
 Contactless temperature sensing anywhere
 Contactless and Accurate distance measurement using Lidar
The wearable computer is developed using a Raspberry Pi controller with a battery, touch
screen display, lidar sensor, temperature sensor all together mounted in a compact way over
wrist strap. This makes a smart, easy to carry wearable computer.
The display is used to interact on the computer. We hereby install linux operating system on
a raspberry pi controller. This allows the user to use all linux features including file storage
and retrieval, tools and browser on the raspberry Pi. We integrate the touch screen display to
allow user to easily interact with windows system. We use internal raspberry pi wifi module
to connect with the internet.
We now integrate a contactless temperature sensor with the raspberry pi controller. We de-
velop a program to fetch the sensor data and display current temperature on the display. Also
if the temperature is above threshold level indicating fever it displays an alert.
Also we integrate a Lidar sensor with the raspberry pi controller and mount it on the wrist
watch. The Lidar is used to transmit distance data captured using the laser return time using
sensor module. This data is then displayed on the display in the program that we create to
show live data. This can be used to measure object length, width, heights as well as other
measurement applications.
