A touchpad is a device commonly used as a substitute for a mouse in a laptop computer. It detects finger movements on its surface and translates them into cursor movements on the screen. Other synonyms for the term touchpad include trackpad, glide pad, and pointing pad. These devices have become widely popular in the era of mobile computing, and they are usually responsive, smooth, and precise. With the touchpad, users have access to multiple gestures and multi-finger tapping actions that enhance their experience. Other variants for the touchpad include the touch-sensitive screen, trackball, and even voice recognition technology that allows users to navigate using voice commands.
