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.

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.

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

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 18

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.

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
