Input devices can be specific or general, where the former is a device design to perform an specific task and the latter is designed to be able to perform a variate, not predetermined number of tasks. They also are either continuous or discrete, and have different sensing methods, mechanical, motion, contact or signal processing. There are Text Input devices, which include the well used keyboards (Qwerty, Dvorak, Soft/Virtual, Chording and some variants) as well as Text Recognition and Gestural Recognition for inputting text. Other common type of input devices are the ones called Position Input devices, e.g, mouse, track-pad, stylus pen, touchscreen, joystick, which can be sensed by force or displacement in several dimensions, i.e. 1, 2 or 3, use position or rate control, be mapped to absolute or relative positions from direct or indirect contact.
