Mouse tracking (also known as cursor tracking) is the use of software to collect users' mouse cursor positions on the computer. [1] This goal is to automatically gather richer information about what people are doing, typically to improve the design of an interface. Often this is done on the Web and can supplement eye tracking in some situations.

The position of the cursor also may be changed by moving the mouse pointer to a different location in the document and clicking. The blinking of the text cursor is usually temporarily suspended when it is being moved; otherwise, the cursor may change position when it is not visible, making its location difficult to follow.
In this text navigation mode the ‘cursor’, often depicted as a blinking vertical line, appears within the text on-screen. The user can then navigate throughout the text by using the arrow navigation keys to cause the cursor to move; typically changing the cursor's location in increments of character position horizontally and of text line vertically.
The concept is similar to a cursor in a text-based environment. However, when considering a graphical interface, there is also a mouse pointer involved. Moving the mouse will typically move the mouse pointer without changing the focus. The focus can usually be changed by clicking on a component that can receive focus with the mouse.
position control vs. rate control; A position-control input device (e.g., mouse, finger on touch screen) directly changes the absolute or relative position of the on-screen pointer. A rate-control input device (e.g., trackpoint, joystick) changes the speed and direction of the movement of the on-screen pointer. translation vs. rotation
CSS is good for making simple and effective hover effects. JavaScript allows more complex and dynamic behaviors when a user hovers over an element. JavaScript can control exactly what happens when a mouseover event occurs. This includes displaying tooltips, changing content, or triggering animations and transitions that are beyond what CSS can do.
The caret, text cursor or insertion point represents the point of the user interface where the focus is located. It represents the object that will be used as the default subject of user-initiated commands such as writing text, starting a selection or a copy-paste operation through the keyboard.
