Before the 1960s the computer had already been invented, but it was used very differently than how we use it today. All commands that users provided to the computer were done through the Keyboard. However, in 1964 Douglas Engelbart invented the first computer mouse (figure 1), which looked not even close to what we use today as a mouse. The figure below is a picture of how a computer mouse looked:

This invention has changed the use of the computers for the better. Commands typed by the user on the keyboard became just a click. As the years went by computer mice have evolved more with a change of shape, body and the parts used to function. In today’s world computer mice come in many forms. For example, some mice come with a wire attached and other wireless mice come wireless, requiring batteries.  

    The mouse I use every day when using my desktop at home is the HP Wireless mouse. The HP wireless mouse is similar to a normal mouse (but without a wire) and it requires batteries to function. It also requires a Universal Serial Bus (USB) to connect to the computer which allows them to communicate along with user commands. Due to this mouse being wireless it can be used to control the computer from anywhere at home as long as its sensor can interact with the computer. The images on the next page show the type of mouse I use and the parts that it requires to function.

Computer mice, in general, have both right buttons to click as well as left buttons along with a scroll wheel.  Unlike a wired mouse, this wireless mouse has a cover shell which can be taken off when importing batteries in it. The right click allows the user to look for options in the computer, the left click allows the user to select whatever they want on the computer, and scroll wheel helps the user to scroll up and down on a website. Right down the scroll wheel, there is a small LED indicator which turns red if the batteries run out of energy, telling the user that the mouse needs its batteries replaced. Especially since this mouse is a wireless mouse it gains its energy from the batteries to function properly. Also, there is a battery locker between the two batteries which helps them to stay in their position correctly. There are also two magnets that are attached vertically between the batteries which hold the mouse cover shell. The mouse also has a tiny USB which connects to the computer allowing the mouse to interact with the computer platform. Looking to the back of the mouse there is a sensor LED which blinks every time the mouse in use telling the user that it is interacting with the computer and the USB. The back also has the on and off switch and a connect button which allows the user to decide whether they would use this mouse when using the computer. It is up to the user if they would connect to the computer or not, which can be controlled at the back of this wireless mouse. This type of wireless mice makes carrying easy where the user just have to grab the mouse along with the USB, to use it on other computer platforms.
