3. 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

4.  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 corner
HISTORY OF MOUSE

5. 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 direction

6. CONTD….
2) Optical Mouse :
 An optical mouse was developed in around 1980
 Optical mouse make use of one or more light-emitting diodes
(LEDs) and an photodiodes to detect movement relative to the
underlying surface
 It is unable to detect movement on surfaces like glass

7. CONTD….
3) Wireless Mouse
 Wireless Mouse does not consist of any cords to connect mouse t
o the PC
 Cordless or wireless mouse transmit data via infrared radiation or
Bluetooth signals
 This consist of Transmitter and Receiver part connected trough wi
relessly

8. 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 diff
erence between the emission of a signal and its return to the sensor, after b
eing reflected by an object

9. COMPONENTS OF EVO MOUSE
IR pulse emitter - you can see the rectangle at the bottom.
 TOF CMOS sensor - on the head of the cute shape between the two
LEDs (LEDs here are indicators of system in operation, not for TOF fun
ction).

11. HOW IT WORKS…?
 The Evo Mouse works on nearly any flat surface and requires very little sp
ace.
 With the Evo Mouse, you can perform common mouse operations using o
nly 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 movements.

12. FUNCTIONS
 It performs functions such as cursor control, right- and left-cli
cking, dragging and double-clicking

13.  The Celluon Evo Mouse offers multi touch capabilitie
s, letting you rotate and zoom on images and scroll te
xt using gestures

14. CONTD….
 It also offers the handwriting recognition, which we can do us
- ing our finger or a pen

15. COMPATIBILITY

16. 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

17. CONCLUSION
 The Evo Mouse changes the way to interact with the computer by
allowing us to use natural hand movements and gestures in order
to control the on screen cursor
 The Evo Mouse is next generation computer mouse
