Woohoos! The mouse is 30 years old!

Introduction
When I first heard Microsoft announcing to the world on 19th April about their new range of optical mice, I was ecstatic. The good-old mouse with balls was invented in 1968. Over 30 years has passed before we actually have something new to replace that ageing design. Microsoft's new optical mouse with IntelliEye™ optical technology promises the elimination of the mouse ball and mouse pad forever! There are two versions of optical mice : The Intellimouse with IntelliEye and the Intellimouse Explorer. The IntelliMouse and the IntelliMouse Explorer both incorporate IntelliEye technology. The main difference is the number of buttons on the mice. The IntelliMouse has three, versus the five on the IntelliMouse Explorer. 


Packed nicely in the box are the two mice. 

Optical Technology? What is that?
Inside the futuristic mouse is an optical sensor and a digital signal processor to replace your traditional mouse ball mechanics. Gone are the dirt and dust which your traditional mouse ball loves to attract. The good thing is, even after years of use, your Intellimouse will remain as responsive as ever! 


Gone are the traditional mouse balls!


Optical Sensor and Digital Signal Processor are the IN thing now!

With the Intellieye optical sensor, the mice are capable of scanning surfaces at a rate of 1,500 times per second to track movement. There are two types of digital camera technologies used widely today; The first being the popular CCD technology and the other uses CMOS technology. The Intellieye uses CMOS technology akin to a tiny digital camera, taking a whopping 1,500 pictures per second on the surfaces beneath the mice. After taking the pictures, the 18 MIPS digital signal processor will analyze these pictures and translate the movement of the mouse to reflect the cursor position on the monitor screen. With "image correlation processing" techniques, the mice provide smoother and more precise pointer movements than ever before.

From the 5 frames above, we can see how the optical sensor tracks the movement of the mouse. The sensor sends the different frames to the digital signal processor, which in turn, translates the movements into corresponding pointer movements on the display. 

 

I love the BALLESS part! Gimme more!
