INTRODUCTION A new concept of pc is coming now that is  E-Ball Concept pc. The E-Ball concept pc is a sphere shaped computer which is the smallest design among all the laptops and desktops. E-BALL was designed by Apostol Tnokovski, a 31

year old Macedonian product designer.

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

PROJECTORS WHICH CAN BE USED IN E- BALL ARE

1. LCD projectors

2. DLP projectors

Page 11: e ball presentation

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.

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.

DISADVANTAGES

More bulky as there are more internal components.

Dead Pixels. LCD panel can fail Screen door effect. Contrast. Portability. Image degradation.

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.

ADVANTAGES

Portability. Higher contrast. Reduced pixilation. Reliability. Sealed optics this makes it better

for use in dusty environment. Less screen door effect.

Page 17: e ball presentation

DISADVANTAGES

Rainbow effect.

Light leakage.

High cost.

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

Page 19: e ball presentation

19

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.

WORKING SCENARIOS

Page 21: e ball presentation

SPECIFICATIONS OF E-BALL A laser keyboard that can be activated by

pressing the particular button.

E-Ball is very small, it is having only 6 inch diameter sphere. It is having 120×120mm motherboard.

E Ball concept pc don't have any external display unit, it has a button when you press this button a projector will pop and it focus the computer screen on the wall which can be adjusted with navigation keys.

21

Page 22: e ball presentation

SPECIFICATION CONT…  If there is no wall then it has a paper sheet holder

that divides into three pieces like an umbrella just after popping up, and it will show desktop on the paper sheet.

E-BALL PC will measure 160mm in diameter and it was designed for Microsoft Windows OS, sorry about the others. 

E-Ball will feature a dual core processor, 250-500GB HDD, 2GB of RAM, integrated graphic card and sound card, 2 x 50W speakers, HD-DVD recorder, wireless optical mouse and laser keyboard, LAN and WLAN card, modem, Web cam and integrated LCD projector.

Page 25: e ball presentation

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.

25

Page 26: e ball presentation

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.
