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.
3
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.
4
The start of E-ball
5
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
6
Elements of E-Ball
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
9
2. DLP projectors
LCD projector.
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.
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.
12
Disadvantages
• More bulky as there are more internal components.
• Dead Pixels.
• LCD panel can fail
• Screen door effect.
• Contrast.
• Portability.
• Image degradation.
13
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.
14
Contd..
15
Advantages
• Portability.
• Higher contrast.
• Reduced pixilation.
• Reliability.
• Sealed optics this makes it better for use in dusty
environment.
• Less screen door effect.
16
Disadvantages
• Rainbow effect.
• Light leakage.
• High cost.
17
18
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
19
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.
20
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! 21
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.
22
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.
23
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
24
25
Scenarios of use
26
The software interface
27
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.
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
28
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.
29
30
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.
