An optical trackpad is an input device based on an optical sensor, which detects the displacement of a finger that is moving on top of it. [1] The sensor is used typically in smartphones, where it replaces the D-pad, and in ultra-portable or ultra-mobile PCs, where it replaces touchpads, pointing sticks or trackballs as pointing device.
The main advantages over a D-pad are:
Next to browsing through menus, it can drive a mouse cursor in point&click interfaces. [2]
In comparison with touchpads, it detects actual skin displacement, instead of displacement of the center of the area being touched, and more similar to pointing sticks or compact trackballs by using experience, but with less physical feedback.
A computer mouse is a hand-held pointing device that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of the pointer on a display, which allows a smooth control of the graphical user interface of a computer.
The technology of computer keyboards includes many elements. Many different keyboard technologies have been developed for consumer demands and optimized for industrial applications. The standard full-size (100%) computer alphanumeric keyboard typically uses 101 to 105 keys; keyboards integrated in laptop computers are typically less comprehensive.
A pointing device is a human interface device that allows a user to input spatial data to a computer. CAD systems and graphical user interfaces (GUI) allow the user to control and provide data to the computer using physical gestures by moving a hand-held mouse or similar device across the surface of the physical desktop and activating switches on the mouse. Movements of the pointing device are echoed on the screen by movements of the pointer and other visual changes. Common gestures are point and click and drag and drop.
A trackball is a pointing device consisting of a ball held by a socket containing sensors to detect a rotation of the ball about two axes—like an upside-down ball mouse with an exposed protruding ball. Users roll the ball to position the on-screen pointer, using their thumb, fingers, or the palm of the hand, while using the fingertips to press the buttons.
A game controller, gaming controller, or simply controller, is an input device or input/output device used with video games or entertainment systems to provide input to a video game. Input devices that have been classified as game controllers include keyboards, mice, gamepads, and joysticks, as well as special purpose devices, such as steering wheels for driving games and light guns for shooting games. Controllers designs have evolved to include directional pads, multiple buttons, analog sticks, joysticks, motion detection, touch screens and a plethora of other features.
An optical mouse is a computer mouse which uses a miniature camera and digital image processing to detect movement relative to a surface. Variations of the optical mouse have largely replaced the older mechanical mouse and its need for frequent cleaning.
A pointing stick is a small analog stick used as a pointing device typically mounted centrally in a computer keyboard. Like other pointing devices such as mice, touchpads or trackballs, operating system software translates manipulation of the device into movements of the pointer on the computer screen. Unlike other pointing devices, it reacts to sustained force or strain rather than to gross movement, so it is called an "isometric" pointing device. IBM introduced it commercially in 1992 on its laptops under the name "TrackPoint", and patented an improved version of it in 1997. It has been used for business laptops, such as Acer's TravelMate, Dell's Latitude, HP's EliteBook and Lenovo's ThinkPad.
A touchpad or trackpad is a type of pointing device. Its largest component is a tactile sensor: an electronic device with a flat surface, that detects the motion and position of a user's fingers, and translates them to a position on a screen, to control a pointer in a graphical user interface. Touchpads are common on laptop computers, contrasted with desktop computers, where mice are more prevalent. Trackpads are sometimes used on desktops, where desk space is scarce. Because trackpads can be made small, they can be found on personal digital assistants (PDAs) and some portable media players. Wireless touchpads are also available, as detached accessories.

Cirque Corporation is an American company which developed and commercialized the first successful capacitive touchpad, now widely used in notebook computers. Cirque develops and sells a variety of touch input products, both in original equipment manufacturer and end-user retail form. Cirque was founded in 1991 by George E. Gerpheide, PhD, and James L. O'Callaghan, to commercialize the GlidePoint technology invented in the 1980s by Gerpheide.
Synaptics Incorporated is a publicly owned San Jose, California-based developer of human interface (HMI) hardware and software, including touchpads for computer laptops; touch, display driver, and fingerprint biometrics technology for smartphones; and touch, video and far-field voice technology for smart home devices and automotives. Synaptics sells its products to original equipment manufacturers (OEMs) and display manufacturers.
A scroll wheel is a wheel used for scrolling. The term usually refers to such wheels found on computer mice. It is often made of hard plastic with a rubbery surface, centred around an internal rotary encoder. It is usually located between the left and right mouse buttons and is positioned perpendicular to the mouse surface. Sometimes the wheel can be pressed left and right, which is actually just two additional macros buttons.
Image stabilization (IS) is a family of techniques that reduce blurring associated with the motion of a camera or other imaging device during exposure.
A projection keyboard is a form of computer input device whereby the image of a virtual keyboard is projected onto a surface: when a user touches the surface covered by an image of a key, the device records the corresponding keystroke. Some connect to Bluetooth devices, including many of the latest smartphone, tablet, and mini-PC devices with Android, iOS or Windows operating system.
A proximity sensor is a sensor able to detect the presence of nearby objects without any physical contact.
Apple Inc. has designed and manufactured several models of mice, trackpads, and other pointing devices, primarily for use with Macintosh computers. Over the years, Apple has maintained a distinct form and function with its mice that reflect their design languages of that time. Apple's current external pointing devices are the Magic Mouse 2 and Magic Trackpad 2.
In computing, an input device is a piece of equipment used to provide data and control signals to an information processing system, such as a computer or information appliance. Examples of input devices include keyboards, computer mice, scanners, cameras, joysticks, and microphones.
In computer science, the general meaning of input is to provide or give something to the computer, in other words, when a computer or device is receiving a command or signal from outer sources, the event is referred to as input to the device.
The fourth-generation iPad Pro is a line of tablet computers designed, developed and marketed by Apple Inc. Two models, with a 12.9 inch or 11 inch screen, were both announced on March 18, 2020, and released on March 25.
The Samsung Galaxy Note 20 and Galaxy Note 20 Ultra are a series of high-end Android-based phablets designed, developed, produced, and marketed by Samsung Electronics as part of their Samsung Galaxy Note series, succeeding the Samsung Galaxy Note 10 series. The phablets were announced on 5 August 2020 alongside the Samsung Galaxy Z Fold 2, Galaxy Watch 3, Galaxy Buds Live and Samsung Galaxy Tab S7 during Samsung's Unpacked Event. It was the final model in the Galaxy Note series, with Samsung beginning to integrate the functionality from the Note series into its S series "Ultra" models, starting with the Galaxy S20 Ultra.
