The document describes the E-Ball, a spherical computer concept measuring 160mm in diameter. It contains all the components of a traditional computer, including a motherboard, hard drive, wireless keyboard and mouse, speakers, and projector. The projector allows the user to project the computer's display onto any flat surface. It works by pressing buttons on the sides to open it and reveal the virtual keyboard and detachable mouse. While portable and space-efficient, the E-Ball also has drawbacks like high cost and difficulty of repairs. Overall, the E-Ball presents an innovative spherical design for miniaturizing the full computer into a small, portable ball-shaped device.

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.

4.  E-Ball is designed to be placed on two stands , opens by
simultaneously pressing and holding the two buttons located on
each side

5.  It has a button when we press this button a projector will pop and it focus the
computer screen on the wall which can be adjusted with navigation keys.
 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.
 Once we turn on the pc, click
on the mouse button to detach
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
E-Ball is very small, it is having only 6 inch
diameter sphere.
It is having 120 120mm motherboard.
Created by Apostol Tnokopvski.
Smallest PC ever made.
160mm round sphere.

7. 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 Integrated graphics and sound
card.
LCD projector Paper holder

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.  Whenever we 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:The 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. This is
done so as to illuminate the users fingers by
the infra-red light beam.
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 qwerty-keyboard, with all the
keys and control functions as in the
keyboard.

13. 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.

14. Projectors
E-BALL that is the concept pc basically uses LCD projector.
LCD stands for liquid crystal display. LCD projectors are systems that display
or project information or video onto a flat surface.
Video signals are comprised of three colors: red, green, and blue.
LCD projectors contain a separate glass panel for each. Each panel consists of
two plates of glass with a layer of liquid crystal between them.
When a charge is applied, the crystals open to allow light through or close to
block it. This opening and closing of pixels is what forms the image.

15. LCD projector
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.

16. ADVANTAGES: LCD is generally more light efficient.
LCD projectors can project bright, vivid images with a low
output lamp.
LCD trends to produce a sharper image.
One benefit of LCD is that it controls red, green, and blue
colors independently
DISADVANTAGES:-More bulky as there are more internal components.
Dead pixels.

17. DLP projectors
DLP-Digital Light Processing.
Worlds only all-digital display solution.
DLP technology is based on
semiconductors called DMD chips.
Invented in 1987 by Texas.
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.

18. ADVANTAGES:Portability.
Higher contrast.
Reduced pixilation.
Reliability.
Sealed optics this makes it better for use
in dusty environment.
Less screen door effect.
DISADVANTAGES:-Rainbow effect.
Light leakage.
High cost.

19. 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

Cost of E-BALL is very high.
It is difficult to understand if any problems occur
in hardware part.

23. 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.
