a computer mouse is an indirect, relative, isotonic, position-control, translational input device with two degrees of freedom (x, y position) and two states (tracking, dragging). a touch screen is a direct , absolute , isometric , position-control input device with two or more degrees of freedom (x, y position and optionally pressure) and two ...
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.
Though it is distinct from the text cursor, the mouse pointer is also being called a cursor or mouse cursor. [13] The pointer commonly appears as an angled arrow (angled because historically that improved appearance on low-resolution screens [14]), but it can vary within different programs or operating systems. The use of a pointer is employed ...
CSI s — This saves the cursor position. Using the sequence CSI u will restore it to the position. Say the current cursor position is 7(y) and 10(x). The sequence CSI s will save those two numbers. Now you can move to a different cursor position, such as 20(y) and 3(x), using the sequence CSI 20 ; 3 H or CSI 20 ; 3 f. Now if you use the ...
Mouse utilities adds tools that enhance mouse and cursor functionality on Windows. Currently, the collection consists of Find My Mouse , which focuses on the cursor's position; Mouse Highlighter , which indicates mouse clicks on the screen; and Mouse pointer Crosshairs , which displays crosshairs centered on the mouse pointer [ 31 ]
If bit 5 of CH is set, that often means "Hide cursor". So CX=2607h is an invisible cursor. Some video cards have 16 scan lines, 00h-0Fh. Some video cards don't use bit 5 of CH. With these, make Start>End (e.g. CX=0706h) Set cursor position AH=02h BH = Page Number, DH = Row, DL = Column Get cursor position and shape AH=03h BH = Page Number

The mouse sends these signals to the computer system via the mouse cable, directly as logic signals in very old mice such as the Xerox mice, and via a data-formatting IC in modern mice. The driver software in the system converts the signals into motion of the mouse cursor along X and Y axes on the computer screen.
