The document describes the E-Ball concept PC, a spherical computer that is the smallest laptop or desktop design. It measures 160mm in diameter and contains components like a motherboard, hard drive, screen projector, mouse, and keyboard. The E-Ball opens by pressing buttons on each side and projects its screen onto a wall using the built-in projector. It has a virtual keyboard and can also project onto paper if no wall is available. The document discusses the E-Ball's advantages like portability and efficiency but also notes its high cost as a disadvantage.

3.  The E-Ball concept pc is a sphere shaped pc which is the smallest
design among all the laptops and desktops.
 This concept PC will measure 160mm in diameter and it was
designed for Microsoft Windows OS.
 This computer has all the features like a
traditional computer, like, mouse, dvd,
large screen display, mother-board,
hard drive, web came ,modem,
LAN& WAN slots etc.

the optical mouse and there is
also a similar laser keyboard.
The unique feature of E-Ball
computer is that when we
close it no one can guess that
whole computer is hidden in
the ball.

6. Size of E-Ball

8. Elements of E-Ball

9. WORKING OF E-BALL
 Press and hold the power button for 5 sec.
Adjust the LCD projector.
Detach the optical mouse.
Activate the virtual keyboard.
Do whatever you want.

10. VIRTUAL KEYBOARD
o A virtual keyboard is a projection keyboard that is projected and
touched on any flat surface
o Virtual keyboard basically uses the principle of sensor
technology and artificial intelligence to let users work on any
surface.

11. ADVANTAGES & DISADVANTAGES
ADVANTAGES:-
Ability to minimize the risk for repetitive strain injuries.
Portability.
Accuracy.
Lack of need for flat or large typing surface.
DISADVANTAGES:-
It is very costly ranging from 150 to 200 dollars.
The room in which the projected keyboard is used should not be very
bright so that the keyboard is properly visible.
Virtual keyboard is hard to get used to. Since it involves typing in thin
air, it requires a little practice. Only people who are good at typing can use
a virtual keyboard efficiently.

12. 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

13. Scenarios of use

14. Advantages of E-Ball:

E-BALL support user defined keyboard layouts.
E-BALL is efficient.
E-BALL is very easy to use.
E-BALL is more secure than other computer.

15. Disadvantages of E-Ball:
Normal operating systems cannot work in these
computers.
Cost of E-BALL is very high.
It is difficult to understand if any problems occur
in hardware part.

16. 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.
