The E-Ball is a concept for a spherical computer that is smaller than any laptop or desktop. It has a diameter of only 6 inches and contains components like a wireless mouse, laser keyboard, LCD projector, hard drive, RAM, and speakers. The keyboard and mouse use infrared rays, lasers, and RF signals. It can project its display onto walls using an LCD or DLP projector, or onto a paper sheet using a built-in holder. While portable and powerful for its size, an E-Ball would have high costs, difficulty with repairs, and require custom operating systems. It represents an extreme example of the ongoing trend of shrinking computer sizes.

3. INTRODUCTION
• The E-Ball is a sphere shaped computer concept which is the smallest
design among all the laptops and desktops have ever made.
• It’s not going to be like a PDA, it’s going to be a PC with all conventional
components namely mouse, keyboard, normal screen.

4. Size of E-Ball
• E-Ball is very small, it is having only 6 inch diameter sphere.
• It is having 120×120mm motherboard.
• Created by Apostol Tnokovski.
• Smallest PC ever made.
• 160mm round sphere.

6. Features of E-Ball:
• It contains wireless optical mouse and laser keyboard, and LCD
projector.
• It has around 350-600GB of Hard Disk Drive.
• It contains 5GB RAM.
• It has two 50W speakers.
• It has LAN and WLAN card and a Web cam.
• i-tech Virtual keyboard
• Dual core processor

7. Working of E-Ball:
• Key board :Infrared rays & laser
• Mouse: RF receiver & RF transmitter
• LCD projector

8. Projectors which can be
used in E-ball are
1. LCD projectors
•DLP projectors

10. Contd…
• Metal halide lamp is emitting the light.
• Series of di-chroic filters are separates light.
• 3 polysillicon panels placed in red, blue, green color's
• These primary color's are making the image.
• Metal halide lamps are output an ideal color temperature.
• LCD technology is used by many manufactures such as
Epson, Hitachi, and NEC.
10

11. Advantages of LCD
• LCD is generally more light efficient than DLP.
• 3LCD projectors can project bright, vivid images with a low
output lamp.
• 1000 lumen LCD is more preferred than 1200 lumen DLP .
• LCD trends to produce a sharper image.
• More accurate color.
• Sharper image
• More light efficient.
11

12. Disadvantages
• More bulky as there are more internal components.
• Dead Pixels.
• LCD panel can fail
• Screen door effect.
• Contrast.
• Portability.
• Image degradation.
12

13. DLP projectors.
• DLP-Digital Light Processing.
• Worlds only all-digital display solution.
• DLP technology is based on semiconductors called DMD
chips.
• DMD chips made up of many tiny mirrors.
• Current DMD chip can produce 1024 shades of grey.
• Found in projectors manufacturers of BenQ,InFocus and
Optoma.

15. Advantages
• Portability.
• Higher contrast.
• Reduced pixilation.
• Reliability.
• Sealed optics this makes it better for use in dusty environment.
• Less screen door effect.
15

16. Disadvantages
• Rainbow effect.
• Light leakage.
• High cost.

17. Laser keyboard
(virtual keyboard)
• A Virtual Keyboard is a projection keyboard that is
projected and touched on any surface
• User operates by typing on or within a wireless or optical
-detectable surface or area rather than by depressing
physical keys.
• Proved nightmare for users
• Way to eliminate finger cramping
17

18. What Actually it is:-
• Keyboard that a user operates by typing (moving fingers)
on or within a wireless or optical-detectable surface or
area rather than by depressing physical keys.
18

19. Technologies used:-
• In one technology, the keyboard is projected optically on
a flat surface and, as the user touches the image of a key,
the optical device detects the stroke and sends it to the
computer.
• In another technology, the keyboard is projected on an
area and selected keys are transmitted as wireless signals
using the short-range Bluetooth technology.
• With either approach, a virtual keyboard makes it
possible for the user of a very small smart phone or a
wearable computer to have full keyboard capability.
• Theoretically, with either approach, the keyboard can be
in space and the user can type by moving fingers through
the air!
19

20. Reasons to use the virtual
keyboard.
• When connected to your handheld computer it is more
convenient to carry around than your laptop.
• It takes up less desk space than a conventional keyboard.
• You could use it with your desktop, laptop or handheld
computer.
20

21. Advantages:-
• Portability
• Accuracy
• Speed of text entry
• Lack of need for flat or large typing surface
• Ability to minimize the risk for repetitive strain injuries
• Flexibility
• Keyboard layouts can be changed by software allowing for foreign
or Alternative keyboard layouts.
21

22. 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

25. The software interface
25
The software interface of E-Ball concept pc is highly stylized
with icons that can be remembered easily that support all type of
windows operating system.

26. Advantages of E-Ball:
• It is portable.
• E-Ball has large memory.
• Useful for making video presentations.
• These have greater speed.
• Supports user-defined keyboard layouts
26

27. Disadvantages of E-Ball:
• Normal OS can’t work in these computers.
• Cost of E-Ball is very high.
• It is difficult to understand if any problems occur in hardware
components.
27

28. Conclusion
• As years 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. This ball computer has taken the
computer technology to new horizons.
