Technology paper ( mouse) - Essay Example

Introduction Technological revolution and the use of computers systems have transformed human perception to almost all operations and tasks. Living in the midst of technological harbor, several changes have been envisaged with the use of computer application, which transforms the society into a digital hub leading to sustainable economy. The use of computer systems has facilitated management, communication, data processing and information security but all these has been made even much easier with an aid of a computer mouse, which is classified as a computer point and draw device [Salvendy,2001,p. 36]. The mouse innovation According to SpringerLink, 2011, p.

[1236], the earliest forms of computers such as the electronic numerical integrators or the main frames never used the mouse technology. This is because their applications were based on command prompt, which only required typing in commands to execute an instruction. However, with the introduction of windows in 1985, a mouse was developed to assist in the maneuvering around the computer different applications. A mouse sizeable enough to fit the palm is made up of two buttons left and right with a trackball at the bottom.

It is meant to detect two dimensional motions relative to the supporting surface. The mouse is meant to be physically beneath the palm with the two fingers resting on the buttons respectively. When the device moves on a surface, the user gets into a position to track, drag select and move files, icons or even folders. Moreover, a mouse allows the user to draw images and navigate almost all applications within a computer system. The first mouse was invented by Douglas Engelbart in 1968 after completing his research concerning studies about the human interpretation with computers.

However, the official launch of this invention was put into public at Xerox Paulo research center in 1970 [SpringerLink, 2011.p. 1236]. Classifications of mouse Since the introduction of mouse into the market, there have been several classifications based on technology, mode of operation and usage. The most common type of mouse in the market includes: Mechanical mouse This type of mouse uses a ball to move the cursor on the surface of the screen. In order to enjoy the best efficacies, a flat pad would be needed to enable the rubber ball which is contained beneath to roll easily.

The rolling ball would triggers the movement of the cursor on to the surface, which further translates into information understood by the computer system [SpringerLink, 2011, p 1236]. Optical mouse Optical mouse uses the sense of lesser rays to help detect the mouse movement in line with the arranged pixels on the surface where the movement is being made. The optical mouse uses red light emitting diode (LED) sensor to induce movement on the surfaces and send signals into the computer for interpretations.

The red light emitting diode (LED) bounces the light off the surface onto the complementary metal-oxide semiconductor (CMOS). This mouse offers, the most effective speed and can be used in almost all surfaces [SpringerLink, 2011, p. 1236]. Wireless mouse This type of mouse usually comes up with additional dongle that are attached to the USB ports. The mouse itself contains a Bluetooth transmitter, which sends signal to the dongle acting as the Bluetooth receiver. The signals would then be interpreted by the computer
