Touchpads are primarily used in self-contained portable [[laptop]] computers and do not require a flat surface near the machine. The touchpad is close to the keyboard, and relatively short finger movements are required to move the cursor across the display screen; while advantageous, this also makes it possible for a user's palm or wrist to move the mouse cursor accidentally while typing. Laptops today feature [[Multi-touch|multitouch]] touchpads that can sense in some cases up to five fingers simultaneously, providing more options for input, such as the ability to bring up the [[context menu]] by tapping two fingers, dragging two fingers for scrolling, or gestures for zoom in/out or rotate. The touchpads with physical buttons now are only hi-end business/professional laptops option.

One-dimensional touchpads are the primary control interface for menu navigation on [[iPod Classic]] portable music players and additional input method on some [[Wacom]] digitizer tablets, where they are referred to as "click wheels", since they only sense motion along one axis, which is wrapped around like a wheel. [[Creative Labs]] also uses a touchpad for their [[Creative Zen|Zen]] line of [[MP3 player]]s, beginning with the Zen Touch. The second-generation [[Microsoft]] [[Zune]] product line (the [[Zune 80, 120|Zune 80/120]] and [[Zune 4, 8, 16|Zune 4/8]]) uses touch for the [[Zune Pad]].

Touchpads also exist for desktop computers as an external peripheral, albeit rarely seen. But touchpad layer can be integrated with [[graphics tablet]] as additional input option.

External computer keyboards can be equipped with integrated touchpads<ref>{{Cite web|last=Yu|first=Justin|title=This Logitech keyboard and touch pad would like the full attention of your hands|url=https://www.cnet.com/reviews/logitech-wireless-all-in-one-keyboard-tk820-review/|access-date=2021-07-06|website=CNET|language=en}}</ref> (particularly keyboards oriented for [[HTPC]] use), and some keyboards can have only touch input surface instead of hardware buttons (a typical solution for clean rooms).<ref>{{Cite web|last=GmbH|first=Systec & Solutions|title=Medical keyboard and stainless steel tablet|url=https://www.systec-solutions.com/en/products/medical-keyboard-and-stainless-steel-tablet|access-date=2021-07-06|website=www.systec-solutions.com|language=en-US}}</ref>

[[Optical trackpad]]s primary can be used as part of ultraportable electronics; some handheld laptops and early smartphones can be equipped with optical trackpads.

On September 9, 2024, Apple unveiled the [[IPhone 16|iPhone 16, iPhone 16 Plus]], [[IPhone 16 Pro|iPhone 16 Pro and iPhone 16 Pro Max]] to feature the single one-dimensional trackpad next to the side button called "Camera Control" which allows the users to take an easier way to take a photos and videos, the force sensor to distinguish between the firm press and the light press and the capacitance touch sensor to distinguish sliding with finger for adjusting the zoom, exposure or depth-of-field.<ref>{{Cite web |title=Apple introduces iPhone 16 and iPhone 16 Plus |url=https://www.apple.com/newsroom/2024/09/apple-introduces-iphone-16-and-iphone-16-plus/ |access-date=2024-09-14 |website=Apple Newsroom |language=en-US}}</ref><ref>{{Cite web |title=Apple debuts iPhone 16 Pro and iPhone 16 Pro Max |url=https://www.apple.com/newsroom/2024/09/apple-debuts-iphone-16-pro-and-iphone-16-pro-max/ |access-date=2024-09-14 |website=Apple Newsroom |language=en-US}}</ref>
