Closeup of a touchpad on an Acer CB5-311 laptop Closeup of a touchpad on a MacBook 2015 laptop. 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 2D motion, to control a pointer in a graphical user interface on a computer screen.
The TouchPad also features an InvenSense 3-axis gyroscope. [1] The TouchPad has three separate physical buttons, a sleep/wake button on the top right, a home button at the bottom of the front that launches the card view or the app launcher and a set of volume rockers at the right of the device.
After a certain period, software perceives the button press not as a single click but as a separate action. This has two drawbacks: first, a slow user may press-and-hold inadvertently. Second, the user must wait for the software to detect the click as a press-and-hold, otherwise the system might interpret the button-depression as a single click.

Wireless keyboards based on infrared technology use light waves to transmit signals to other infrared-enabled devices. In case of radio frequency technology, a wireless keyboard communicates using signals which range from 27 MHz to up to 2.4 GHz. The majority of wireless keyboards today work on 2.4 GHz radio frequency.
If a pen is used the left-click ripple is colorless instead of blue and the right-click ring is a thinner ring that appears closer to the pen tip making contact with the screen. A click (either left or right) will not show the touch pointer, but swiping would still show the pointer which would follow the pen tip.
