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 going to be a PC with all conventional components namely mouse, keyboard, normal screen.

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.

The start of E-ball

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

Elements of E-Ball

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

Projectors which can be used in E-ball are1. LCD projectors •DLP projectors

2. DLP projectors

LCD projector.

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.

Contd..

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

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.

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!

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.

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.

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

Scenarios of use

The software interface 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

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.

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.
