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.
