The document describes the E-Ball, a concept for a spherical computer. Key aspects of the E-Ball include its small 6-inch diameter size, LCD projector for displaying content on walls or paper, and laser keyboard that projects onto surfaces. The E-Ball would contain standard computer components like a hard drive, RAM, and processor in a portable, sphere-shaped device for presentations or use when a traditional computer is not available or practical.

- 5. 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. 5
- 6. Size Of E-Ball • E-Ball is very small, it is having only 6 inch diameter sphere. • It is having 120×120mm motherboard. • Smallest PC ever made. • 160mm round sphere.

- 8. Features of E-Ball • It contains wireless optical mouse and laser keyboard, and LCD projector, Paper holder. • 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 8

- 12. Projectors which can be used in E-ball are 1. LCD projectors 2. DLP Projectors 12
- 13. LCD projector 13
- 14. 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. 14
- 15. 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. 15
- 16. Disadvantages More bulky as there are more internal components. Dead Pixels. LCD panel can fail Screen door effect. Contrast. Portability. Image degradation. 16
- 17. 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. 17

- 19. Advantages Portability. Higher contrast. Reduced pixilation. Reliability. Sealed optics this makes it better for use in dusty environment. Less screen door effect. 19
- 20. Disadvantages Rainbow effect. Light leakage. High cost. 20
- 21. 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 21
- 22. 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. 22
- 23. Advantages of Virtual Key-Board:- • 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. 23
- 24. 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 24

- 27. 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 27
- 28. Disadvantages of E-Ball It support only Microsoft Windows OS,not any other OS support. Cost of E-Ball is very high. It is difficult to understand if any problems occur in hardware components. Plane surface required for using the keyboard 28
