Introduction

The E-Ball is a sphere shaped computer concept which is the smallestdesign 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 allconventional components namely mouse, keyboard, normal screen.




Conclusion

Conclusion


The start of E-ball




Conclusion


Working of E-Ball:

Key board :Infrared rays laser

Mouse: RF receiver RF transmitter

LCD projector




Conclusion


Features of E-Ball:

It contains wireless optical mouse and laser keyboard, and LCDprojector.

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




Conclusion

LCD projectorsDLP Projectors:

LCD projectors




Conclusion


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.




Conclusion



Advantages

LCD is generally more lightefficient than DLP.

3LCD projectors can projectbright, vivid images with a lowoutput lamp.

1000 lumen LCD is morepreferred than 1200 lumen DLP.

LCD trends to produce asharper image.

More accurate color.

Disadvantage

More bulky as there are moreinternal components.

Dead Pixels.

LCD panel can fail

Screen door effect.

Contrast.

Portability.

Image degradation.




Conclusion


LCD 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.

Conclusion



Advantages

Portability.

Higher contrast.

Reduced pixilation.

Reliability.

Sealed optics this makes itbetter for use in dustyenvironment.

Less screen door effect.

Disadvantage

Rainbow effect.

Light leakage.

High cost.

Virtual Keyboard

A Virtual Keyboard is a projection keyboard that is projected andtouched on any surface

User operates by typing on or within a wireless or optical -detectablesurface or area rather than by depressing physical keys.

Proved nightmare for users

Way to eliminate finger cramping.




Conclusion


What Actually it is:-

Keyboard that a user operates by typing (moving fingers) on or withina wireless or optical-detectable surface or area rather than bydepressing physical keys.




Conclusion


Technologies used:-

In one technology, the keyboard is projected optically on a flat surfaceand, as the user touches the image of a key, the optical device detectsthe stroke and sends it to the computer.

In another technology, the keyboard is projected on an area andselected keys are transmitted as wireless signals using the short-rangeBluetooth technology.

With either approach, a virtual keyboard makes it possible for theuser of a very small smart phone or a wearable computer to have fullkeyboard capability.

Theoretically, with either approach, the keyboard can be in space andthe user can type by moving fingers through the air!




Conclusion


Reasons to use the virtual keyboard.

When connected to your handheld computer it is more convenient tocarry 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.




Conclusion


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 orAlternative keyboard layouts.




Conclusion


If there is no wall:-

When we are working in an open place we can make use of a papersheet 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.




Conclusion


Scenarios of use:




Conclusion


The software interface:

The software interface of E-Ball concept pc is highly stylized with iconsthat can be remembered easily that support all type of windows operatingsystem.




Conclusion


Advantages and Disadvantages of E-Ball

Advantages of E-Ball

It is portable.

E-Ball has large memory.

Useful for making videopresentations.

These have greater speed.

Supports user-defined keyboardlayouts

Disadvantage of E-Ball

Normal OS can’t work in thesecomputers.

Cost of E-Ball is very high.

It is difficult to understand ifany problems occur in hardwarecomponents.




Conclusion

Conclusion

As years passes, the computer size is becoming smaller.

Today’s technology is at its peak point beyond what we could everimagine.

New inventions and innovations are emerging on daily basis.

Our imaginations have dressed into reality and today it has becomepossible to have a whole computer in our pocket all the time. Thisball computer has taken the computer technology to new horizons.
