The document describes the E-Ball concept PC, a spherical computer that is the smallest design compared to laptops and desktops. The E-Ball has a 6 inch diameter and contains all the conventional components of a computer, including a virtual keyboard, processor, RAM, hard drive, speakers, networking cards, webcam and projector. It projects a keyboard, display, and mouse onto surfaces using its embedded projector and optical sensors. The E-Ball stands upright using built-in stands and buttons, and its components are accessible through popping out of the spherical body.

2. INTRODUCTION:
● The E-Ball concept PC is a sphere shaped computer which is the smallest
design among all the laptop and desktops.Soon E-BALL based computer
will be the new pc to be used in the near future.
● It’s going to be a pc with all conventional components like mouse,keyboard,
normal screen.
● E-Ball concept pc don’t have any external display unit.

3. CONCEPT:
● The body of E-BALL is made up of aluminium and plastic parts.
● E-BALL is the smallest among all the PCs developed so far as it has
120*120mm motherboard and is 6 inch in diameter.
● The E-BALL pc has all the features and elements of conventional computer
like mouse, keyboard, display etc...

4. ELEMENTS:
● Virtual Keyboard
● Dual core processor
● 2GB RAM
● 350-500GB hard drive
● speakers
● LAN & WAN card
● Modem
● Web cam
● LCD projector

6. WORKING:
● The first thing before starting the E-BALL pc is to put it into standing position.
● For this press two buttons on the sides of E-BALL for 5 seconds and the
stands are automatically opened and adjusted so as to hold the E-BALL
pc in position.
● After this the focus,directions etc.. can be adjusted using the navigation
buttons.

7. DISPLAY UNIT:
● When the stands has been opened and the system has been turned on,
it becomes functional only when the screen or the display unit is available.
● The display unit is not physically present or attached on to the E-BALL.
● Rather,with the help of projector popping up out of the E-BALL PC,the
display unit can be projected on to the wall which can work as screen.

8. KEYBOARD:
● The E-BALL PC has a laser keyboard which is concept keyboard which is
visible only when the PC is in working mode.
● It recognizes your fingers with the help of your infrared sensors when you
are typing at a particular place.
● The Virtual Laser Keyboard projects a full-size keyboard onto a flat surface.
● It uses sensor technology.It has three components
1.sensor module
2.IR light source
3.Pattern Projector

9. PROJECTOR:
● A tiny LCD projector is embedded inside the E-BALL.
● LCD projector is a type of projector based on liquid crystal displays which can
display images, data or video on screen or flat screen.
● With this projector you can full size media onto whatever is near at hand.

10. OPTICAL MOUSE:
● There is an optical mouse which is normally attached to the body of the
E-BALL.
● The mouse can be detached from the body of the E-BALL by pressing
the mouse detaching button on the left hand side of the PC body at the
front.
● It is wireless device which uses the
light emitting diode for purpose of
tracking movement of optical mouse.
