What is the most common pointing device found on laptops? In fact, there are several. Each one has its own unique use and can be used in many different applications. The three most popular pointing devices are listed below, along with a description of the device’s use.
MOUSE: A mouse is the most common pointing device found on laptops. A mouse is a small, lightweight input device that you can press and hold with your palm. A trackpoint is what moves your mouse pointer when you make contact with a surface. A trackpoint can be used to scroll text, zoom in and out of images, or even to reposition your image on the desktop. A trackpoint and mouse are a very common combination for input devices, due to their universal use and great comfort.
TOUCHPAD: A touchpad is also common on laptops. A touchpad is like the trackpoint, but it has no moving parts, making it more aesthetically pleasing. Instead of moving your cursor to click, as with a trackpoint, you touch your screen to activate the touchpad. A touchpad also allows you to perform other tasks aside from clicking and holding the keys on your keyboard, including playing games, viewing images, and tapping images.
NOTE: An isometric view is different from an isochronous view. An isometric view displays an object at a constant speed without any motion, whereas an isochronous view shows an object that is rapidly changing in shape, such as a star, as the Earth spins on its axis. An isometric pointing device uses an isometric camera to point at an object, and records the position every time the object moves, in the same exact way as the GPS system on your car would. This is why many cars on the road today have GPS built in.
FEET MACHINES: In computers and laptops, there are two parts that come together to form a pointing device – the flat surface and the foot mouse. The flat surface is what your fingers rest on. And the foot mouse is what moves your cursor, making it easier to point. A common example of this is the computer mouse. While the two parts of the mouse are obviously very different, they are often interchangeable.
TRACK POINT: The track point is what keeps the user from accidentally clicking the wrong button or scrolling to the wrong location on the screen. Because there are so many different track points, it is difficult to memorize where all your tracks point. A common way to memorize your track point is to have a piece of paper, such as a note card, with all your track points written on it.
JOY ROOM: Most of today’s laptops are equipped with a joystick. This basically allows the user to emulate the experience of operating a mouse or a keyboard. There is actually a motor inside the Joystick, which rotates the stick based on what you are pressing. This makes controlling the direction of the stick easier than you could imagine. Another commonly used joystick is the throttle, which allows users to scroll up and down the screen easily. There are even special joysticks designed for racing cars, although these are not as popular.
BUTtons: One of the biggest gripes against laptops is the fact that the user has to physically move the mouse to click, although this is really not necessary. When you press a button on a PC, the hardware recognizes the request and sends it to the operating system. Once it has been recognized, it passes control to the application software, which is what allows the user to perform operations with the computer. So technically, pressing a button on your computer is not what is the most common, but pressing the appropriate number of buttons. The main article on this is going to touch on some of the more popular buttons that people tend to use for various tasks, along with a description of how they work.
