INTRODUCTION Designer Apostol Tnokovski created the smallest PC

ever made. It is definitely small when it comes to the size but as all good things come in small packages, this tiny round PC is no exception. It is loaded with all features that you can only dream of to have in a regular PC.

The E-Ball concept pc is a sphere shaped pc which is the smallest design among all the laptops and desktops. It supports only windows operating systems.

E-Ball is very small, it is having only 6 inch diameter sphere.

It is having 120×120mm motherboard.

FEATURES OF E-BALL

It has around 350-500 GB of hard disk.

It contains about 5GB of RAM.

It has two 50W speakers.

It has Dual –core processor.

It contains wireless optical mouse .

It contains a laser keyboard.

It contains a LCD projector.

It has LAN and WLAN card

It also contain a Web cam.

SOFTWARE INTERFACE

The software interface of E-Ball concept PC is highly stylized with icons that can be remember easily that support all type windows operating system.

VIRTUAL KEYBOARD

10

A virtual keyboard is a projection keyboard that is

projected and touched on any flat surface. It basically uses the principle of sensor technology and

artificial intelligence to let users work on any surface.

Whenever you 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:-

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.

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.

PROJECTOR

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

These devices use dichroic mirrors to split the light from the input source nto red, green, and blue components. Each then passes through the corresponding panel, where pixels form an image. The three colors are then recombined in a prism before being projected through a lens. LCD projectors use separate panels for each color because it results in better color saturating than using a single panel for all three.

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. Suffers from Screen door effect.

16

WORKING OF E-BALL Press and hold the power button for 5 sec. 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

Detach the optical mouse. Activate the virtual keyboard. Do whatever you want.

17

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

ADVANTAGES & DISADVANTAGES ADVANTAGES:- E-BALL is portable. E-BALL has large memory. E-BALL is useful for making video presentation. E-BALL support user defined keyboard layouts. E-BALL is efficient. E-BALL is very easy to use E-BALL is more secure than other computer. E-BALL takes less place physically in comparision to

desktops and laptops. DISADVANTAGES It supports only windows operating system. Cost of E-BALL is very high. It is difficult to understand if any problems occur in

hardware part.

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.
