INTRODUCTION The Evo Mouse is the evolution of the computer mouse. The evolution mouse is the latest and portable

device develop-ed by Folks from Celluon Evo Mouse is a dog – shaped device that functions

differently and not like the other mouse

The first functional mouse was actually demonstrated by Douglas Engelbart in 1964

It was manufactured from wood and featured two gear-wheels perpendicular to each other

This mouse was first used with the Xerox Alto computer system in 1964

As can be seen by the picture, the mouse was much larg-er than today's mouse, square, and had a small button in the top right cor-ner

HISTORY OF MOUSE

CONTD….1) Mechanical Mouse

Bill English created a ball mouse in 1972 The ball mouse replaced the external wheels

with a single ball that could rotate in any direc-tion

CONTD….2) Optical Mouse :

An optical mouse was developed in around 1980 Optical mouse make use of one or more light-emit-

ting diodes (LEDs) and an photodiodes to detect movement relative to the underlying surface

It is unable to detect movement on surfaces like glass

CONTD….3) Wireless Mouse

Wireless Mouse does not consist of any cords to connect mouse to the PC

Cordless or wireless mouse transmit data via infrared radiation or Bluetooth signals

This consist of Transmitter and Receiver part con-nected trough wirelessly

BASIC PRINCIPLE The basic principle used in the Evo Mouse is "time of flight" principle This principle is used to detect the motion of objects based

on the time difference between the emission of a signal and its return to the sensor, after being reflected by an object

COMPONENTS OF EVO MOUSE

IR pulse emitter - you can see the rectangle at the bot-tom. TOF CMOS sensor - on the head of the cute shape be-tween the two LEDs (LEDs here are indicators of system in operation, not for TOF function).

HOW IT WORKS…? The Evo Mouse works on nearly any flat surface and re-

quires very little space. With the Evo Mouse, you can perform common mouse op-

erations using only your fingers You can control the cursor, click and select, double-click,

right-click and drag with basic hand gestures It tracks smoothly to your comfortable and natural move-

ments.

FUNCTIONS

It performs functions such as cursor control, right- and left-clicking, dragging and double-clicking

The Celluon Evo Mouse offers multi touch capabilities, letting you rotate and zoom on images and scroll text using gestures

CONTD….

CONTD…. It also offers the handwriting recognition, which

we can do us- ing our finger or a pen Fig.: Functions of Evo Mouse

COMPATIBILITY

ADVANTAGES

Works almost on any surface Little space needed ( space saver ) Offers Multi-touch functionality Works with all desktop & laptop PC It connects via Bluetooth or a standard USB port

CONCLUSION

The Evo Mouse changes the way to interact with the computer by allowing us to use natural hand move-ments and gestures in order to control the on screen cursor

The Evo Mouse is next generation computer mouse
