There is no official full form of MOUSE because MOUSE is not an abbreviation. Instead, MOUSE is a hardware device used in computer systems. However, there are some full forms used for the word MOUSE as a hardware device.
MOUSE – Manually operated user selection equipment
MOUSE – Mechanically operated user signal engine
The word MOUSE is not a short form because it is a name derived from the shape it has. The name MOUSE is derived from the rat as the hardware device MOUSE has a shape similar to a rat.

About MOUSE
MOUSE is also called a computer Mouse which is a handheld pointing device. Mouse detects two-dimensional motion relative to a surface. This motion is normally translated into the motion of a pointer on a screen or monitor. This allows a smooth control of the graphical user interface of the computer.
In 1968 the first-ever public launching happened of a MOUSE controlling a computer system. These MICE originally used two separate wheels to track the movement across the surface.
Out of these two wheels, one was in the X-dimension and another wheel was in the Y-dimension.
However, in next coming years after this launch, the standard design for MOUSE was shifted to use a ball rolling on a surface to notice motion.
This MOUSE used optical sensors that had no moving parts and these were modern MICE. All MICE were connected to a computer by a cable. However, these new mice were wireless and only depended on short-range radio communication with the connected system.
To move the cursor computer MOUSE had one or more buttons that allowed their operations as a selection of menu items on the computer screen.
These MICE mostly featured other elements like touch surfaces and scroll wheels that enabled additional control and dimensional input in the computer system.
MOUSE History
The initial use of this term MOUSE to computer pointing device that we know today was in Bill English’s July 1965 publication named “computer-aided display control”. It was originated from its similarity to the shape and size of a mouse or rat where the cord or wire of MOUSE resembled the tail of the rat. However, as this MOUSE got popular as a pointing device they became wireless and that made it less similar to the rat.
In 1946 a trackball was invented by Ralph Benjamin as part of the post-world war II era fire control radar plotting system which was called the comprehensive Display System or CDS.
In 1947 the devices were planted however only a prototype that used metal ball rolling on two rubber-coated wheels was built. Here the device was kept as a military secret.
A British electrical engineer Kenyon Taylor who worked in a collaboration with Tom Cranston and Fred Long staff built early trackball. Kenyon Taylor was a part of the original Ferranti Canada who worked on the Royal Canadian Navy’s DATAR system in 1952.
Logitech introduced the P4 MOUSE in 1982 at the Comdex trade show in Las Vegas. It was their first-ever hardware mouse.
Microsoft also made the decision to make the MS-DOS program Microsoft word mouse compatible in the same year and then developed the first-ever PC compatible mouse. These MOUS of Microsoft were shipped in 1983 which was the start of the Microsoft Hardware division of the company.
Until the appearance of the Macintosh 128K in 1984 MOUSE was relatively obscure.
