Power user @ Facebook [INFOGRAPHIC]

Power users .....! Who are they ?

POWER USER
Power users are those Facebook users who can do more in FB than what the average users do ... Suppose if normal users 'like' an average of 4 to 5 items a month , power users 'like' 4 to 5 items a day . That sounds pretty high for you right ? And if you come under the category of power users you are lucky .....

The Science of Projection keyboards

Most of us would have come to know that such things called 'Projection Keyboards' exists only after the video that featured the rumored iPhone 5 was put in Youtube . It happens .........!Sometimes great techs. like this don't get their recognition like the Android OS ,at its first ......

Optical keyboards are just like the same old favs. but it's way of reception of input is different .Let me get it clear . There is no difference except for the way you give the input to the device ....

HOW THEY WORK

I'm not gonna confuse you with the complex ' Text Book " Definitions ... I'll Compare the Normal one and the new one ..

• The normal keyboard which you use has a few keys each one codes for a letter : Say 'A' , 'B' Etc :- . When you get to press one of those keys the circuit under it gets the signals . Then the signal gets processed and goes into the computer then onto the screen
• The Scenario in Projection keyboards :- Here you don't have physical keys instead they can be called virtual  ....... the device projects light ( Infra Red light ) as the name says the keys are displayed in red colour .. The device has a light transmitter and a receiver ( More commonly called a camera ) to intercept the input ... When any key pressed there is a distraction and of course a reflection of the light emitted from the transmitter which the camera receives detects the angle at where there is a disturbance in the reception .. The circuit process the input and send them to the CPU 

ADVANTAGES OVER THE NORMAL ...

There are many but let me list a few 

• Less space consumption 
• Energy efficiency 
• Modern 
• Makes a way for a great leap of innovation in the light emission and reception technology 

CONDITIONS !

• The keys work good only on a flat Non - Reflective surface like ( Office desk , Table Etc : - )

If you think this information is not enough , wait for a while while we get our next post on a detailed study on Projection keyboards ( More theoretical )
