The E-Ball is a spherical computer that is the smallest PC ever made, with a diameter of only 6 inches. It contains features of a traditional computer like a motherboard, hard drive, wireless keyboard and mouse, LCD projector, and speakers. The virtual keyboard is projected onto any flat surface using infrared sensors to detect keystrokes. While innovative, the E-Ball has high production costs and operating systems may have trouble running on its unique design.

3. History
• Designer Apostol Tnokovski has replaced the good
old pc from the shackels of the monotonous squares
and rectangular shape with his newly designed
wonder in a spherical shape.
• According to Apostol it is the best shape in nature and
it draws everybody attention. It is the smallest PC
ever made

4. Introduction
 The E-Ball computer is a sphere shaped computer
which is the smallest design among all the laptops
and desktops.
 This computer has all the features like a traditional
computer ,like mouse , dvd , large screen display ,
mother-board, hard drive , web came , modem etc.

5. Size of E-Ball
E-Ball is very small , it is having only 6 inch
diameter sphere.
It is having 120x120 mm motherboard.
Smallest PC ever made.
160 mm round sphere.

6. Features of E-Ball
 It contains wireless optical mouse and laser keyboard and LCD
projector.
 It has around 350-600 GB of hard disk drive.
 It contains 5GB ram.
 It has two 50W speakers.
 It has LAN and WLAN card and a Web cam.
 It has Virtual keyboard.
 Dual core processor.
 Integrated graphics and sound card.
 LCD projector Paper holder.

7. Working of E-ball
Press and hold the power button for 5 sec.
Adjust the LCD projector.
Detach the wireless optical mouse.
Activate the virtual keyboard.
Do whatever you want.

8.  E-Ball is designed to be placed on two stands , open by simultaneously
pressing and holding the two buttons located.

9. IF THERE IS NO WALL?
 When we are working in an open place we can make use of a
paper sheet as a screen.
 Paper sheet holder is placed at the back panel of this
computer.
 The holder can be opened by pressing it in the lower part.

10. Virtual keyboard
A virtual keyboard is a projection keyboard that is projected on any
flat surface.
Virtual keyboard basically uses the principle of sensor technology
and users work on any plane surface.
 It has three components
 Sensor module
 IR-light source
 The pattern projector

11.  Whenever you press the keyboard button, it is projected optically
on the flat surface and, as the user touches the image of the key, the
optical device detects the stroke and sends it to the computer.
• Virtual keyboard basically consists of three components:-
Sensor module:-
The Sensor Module serves as the eyes
of the Keyboard Perception technology.
The Sensor Module operates by
locating the user's fingers in
3-D space and tracking the
intended keystrokes.

12. IR-light source:-
 The infrared Light Source emits a
beam of infrared light.
 This light beam is designed to
overlap the area on which the
keyboard pattern projects.
The pattern projector:-
 The pattern projector basically presents
the image of the keyboard.
 This image can be projected on any flat
surface .
 The projected image is that of a
standard keyboard with all the keys
and control funcions.

13. Projectors
E-Ball computer have
basically uses LCD projector.
LCD stands for liquid crystal
display.
LCD projectors are systems
that display or project
information or video on to a
flat surface.
Video signals are comprised
of three colors :red , green
and blue

15. Scenarious of use

16. Software Interface
First E-Ball is designed for Microsoft windows.
The software interface of E-Ball concept PC is highly stylized with
icons.

17. Advantages
E-ball has large memory.
E-ball supports userdefined keyboard layouts.
These have greater speed than other computer.
E-Ball is very easy to use.
E-Ball is more secure than other computer.
E-ball is portable.

18. Disadvantages
Normal operating systems
cannot work in these computers.
Cost of E-Ball is very high.
There are difficult to understand
if any problems occur in
hardware part.

19. CONCLUSION
 As the year passes, the computer size is becoming smaller.
 Today’s technology is at its peak point beyond what we could
ever imagine.
 New inventions and innovations are emerging on daily basis.
 Our imaginations have dressed into reality and today it has
become possible to have a whole computer in our pocket all
the time.
 At last this ball technology has taken the computer technology
to new horizons.
