INTRODUCTION
“Invisible Mouse” is a computer mouse
that allows you to interact with a
computer with a mouse in the same way
as usual - except that there is no mouse
hardware.
An invisible computer mouse that
provides the familiarity of interaction of a
physical mouse without actually needing
a real hardware mouse.
ABOUT THE INVISIBLE MOUSE
A group of scientists developed this
Invisible Mouse in the MIT Lab in
Cambridge.
The researchers, Pranav Mistry, Liyan
Chang, and Pattie Maes, developed an
infrared (IR) laser beam and associated
camera that could be incorporated into the
computer so that a plane of IR laser would
be created just above the surface on which
the computer is resting.
The user acts as though a physical
mouse were present and the laser beam is
intersected by the hand, and parts of the
hand are shown up as bright spots of light
that change position as the hand moves.
The built-in camera then interprets the
changes in position of the hand and
fingers and translates them as moves of
the mouse and clicks on the two buttons,
and the cursor on the screen moves as if
the user was operating a physical mouse.
The Invisible Mouse invention
removes the requirement of having a
physical mouse altogether but still
provides the intuitive interaction of a
physical mouse that we are familiar
with.
The user cups their hand, as if a
physical mouse was present
underneath, and the laser beam
lights up the hand which is in contact
with the surface.
WORKING OF INVISIBLE MOUSE
consists of an Infrared (IR) laser beam
(with line cap) and an Infrared camera.
Both IR laser and IR camera are
embedded in the computer.
The laser beam module is modified with
a line cap and placed such that it creates
a plane of IR laser just above the surface
the computer sits on.
The IR camera detects those bright IR blobs using computer vision.
The change in the position and arrangements of these blobs are interpreted as mouse cursor movement and mouse clicks. As the user moves their hand the cursor on screen moves accordingly.
When the user taps their index finger, the size of the blob changes and the camera recognizes the intended mouse click.
