A computer mouse is a hand-held pointing device that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of a pointer on a display, which allows a smooth control of the graphical user interface of a computer. The first public demonstration of a mouse controlling a computer system was in 1968.
The name “mouse” is derived from its shape, which looks a lot like a mouse, its connecting wire that one can imagine to be the mouse’s tail, and the fact that one must make it scurry along a surface. The trackball, another pointing device, has an exposed protruding ball that is operated by rolling and is often called an upside-down mouse (see comparison).
Early models were open to the air underneath, permitting contamination with dirt particles or other foreign matter. Modern mice have usually been designed with caps or other protective shields over their internal mechanisms to prevent this problem.
Your choice of mouse can greatly affect your productivity and comfort. If you are a graphic designer, you might prefer a programmable gaming mouse; if you do a lot of presentations, you may want a presenter mouse with a laser pointer and built-in memory; if you need to work on the go, a wireless mouse will be ideal.
To help you choose the right one, here is a list of the most important computer mice features.
The computer mouse as we know it today was invented by Douglas Engelbart in 1964 and was patented on November 17, 1970. A video of his groundbreaking work can be seen below.
The original mouse was made out of wood. The name mouse came about because the tail coming out of the back reminded people of a mouse (xkcd has a very accurate take on this). Early versions used metal wheels that rolled along the surface to detect motion, but modern mice usually use optical technology or laser to detect movement.
There are three main types of computer mice: Mechanical, Optical, and Laser.
Mechanical mice use a rubber or metal ball on the underside that rolls as the mouse is moved. There are small wheels inside the mouse that detect which direction the ball is rolling.
Optical mice use an LED and a tiny camera to track movement across a surface. They often have a much higher tracking speed than mechanical mice because they don’t rely on moving parts but rather small changes in position over time. They also don’t require cleaning as they don’t collect dust and dirt like mechanical mice do.
Laser mice provide more accuracy than optical mice but use more power and cost more to produce (the first consumer laser mouse went for $99). Laser diod
The computer mouse is a “point and click” input device that was invented in the 1960s. It is the primary input device for graphical user interfaces (GUIs). The first commercial mouse was invented by Douglas Engelbart of SRI International in the mid-1960s.
The word mouse refers to the shape, cord and button of this device. The term “mouse” was coined at SRI by Jack Hawley, who designed the first prototype. Doug Engelbart came up with the name “mouse”, because it looked like a mouse with a tail.
The earliest versions had only one button, but today most mice have two or more buttons to perform different functions like opening web pages and selecting text.
The computer mouse is a hardware input device which is used with a computer in order to perform various functions such as pointing, selecting and dragging. An ordinary computer mouse consists of an object held under one hand, with one or more buttons. The mouse is placed on a flat surface (eg. desk) which is referred to as the mouse pad.
There are several types of mice available today, although most modern day mice would be considered optical mice. These are great because they do not require any external power supply or ball cleaning. These optical mice use a light emitting diode (LED) and a digital camera to track the movement of the mouse against the surface that it slides on. This type of mouse is also referred to as an LED mouse or optical tracking mouse.
Early computers also made use of other forms of input devices such as trackballs and pointing sticks in order to move the cursor around on screen. Some computers also had joysticks installed for gaming purposes. However, in today’s market these devices are usually found in laptops rather than desktops.
In most cases, you will find that a computer uses the mouse to interact with the graphical user interface (GUI). This allows the user to move around between icons on screen by using
I have been using a Logitech MX Revolution mouse for some time now. I really like everything about it, except the thumb button. The thumb button is just plain annoying. It is placed very awkwardly and is difficult to press. I would love to disable it, but Logitech’s SetPoint software doesn’t allow this. In addition, even if you wanted to remove the button physically, then you would have no way of getting into the mouse because it is sealed. You need a special screw driver that only Logitech has access to.
Logitech could have made their SetPoint software open source so that third parties could create custom versions of it that allow customization of the mouse’s buttons in more ways than SetPoint allows. They could also provide an open specification for their mice so that third parties can build accessories for their mice such as thumb buttons that can be installed on other parts of the mouse. This would enhance the usability of their mice and make them much more appealing to people with different hand sizes and shapes. It would also stimulate sales of their mice because people would feel like they are getting a more customized product when they buy one.
The first computer mouse was not invented by Apple. It wasn’t even invented by Xerox, which is widely regarded as having pioneered the technology. The computer mouse was invented by Doug Engelbart, who patented the idea in 1970. The original mouse was a box with two wheels that rotated on different axes, which provided x and y coordinates to the computer that helped it determine the movement of the mouse.
Engelbart’s patented design was inspired by a fellow researcher at Stanford Research Institute. William English had taken up the job of building a graphical user interface for SRI, but could not figure out how to implement a pointing device into his design. He designed a wooden shell for an analog device that used wheels for coordinates, and passed it on to Engelbart for advice. Engelbart further developed the design, and built upon its use in the Augmentation Research Center at SRI with funding from DARPA. The patent was granted in 1970 and became public domain 17 years later after an extension request failed to pass Congress.
The first mice used wheels to measure movements, but were difficult to control because they were too sensitive and had no momentum. Later models changed their design to include a ball bearing so that users could move their mouse more easily. However, this led to problems with
