On the average, you hold your smart phone with one hand
and operate it with your thumb or touch it with other hand
by touching the screen. As you move over the Internet
screens or read an article by using your fingers,
the display screen of your cell phone easily gets dirty.
Sometimes your thumb hides the screen.
In order to solve this problem,
we attached sensors on the edge of screen so that you
can operate your smart phone without touching the screen.
