The document describes E-Ball, a spherical computer measuring 160mm in diameter that contains all the components of a traditional computer. E-Ball uses an LCD projector to project a virtual keyboard and display onto any flat surface. It has features like a wireless mouse, large storage, RAM and processors. To use it, the user presses the power button to open E-Ball and projects the keyboard and screen. E-Ball allows computing in small spaces and on the go. While portable and powerful, it also has high costs and potential hardware issues.

3. INTRODUCTION
E-Ball is Created by Aposto Tnokopvski
The E-Ball computer is a sphere shaped
computer which is the smallest design
among all the laptops and desktops.
This concept PC will measure 160 mm 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 etc.

only 6 inch diameter sphere.
It is having 120×120 mm
motherboard.
Smallest PC ever made.
160 mm round sphere.

8. 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.

9. 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.
9

10.  Whenever we press the keyboard button, then 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.
 The Sensor Module operates
by locating the user's fingers
in 3-D space and tracking the
key strokes.
10

11.  IR source light:-
 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 projecter:-
 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
functions.

12. 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 onto a
flat surface.
 Video signals are comprised of
three colors: red, green, and
blue.

13. IF THERE IS NO WALL
 When we are working in an open place we can 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

15. Advantages of E-Ball:
E-BALL is portable.
E-BALL has large memory.
E-BALL is useful for making video presentation.
E-BALL support user defined keyboard layouts.
These have greater speed than other computer.
E-BALL is very easy to use.
E-BALL is more secure than other computer.
15

16. Disadvantages of E-Ball:
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.

17. 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.
 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.
