A trackball is an input device for controlling the cursor (mouse) the ball works the same way the ball on a mouse works except that you use your hand to turn the ball. See: http://en.wikipedia.org/wiki/Trackball
Advantages of using track ball?
A tracker ball in integrated with a keyboard saving space the for a mouse pad. the big disadvantage is you are stuck with your hand in that position I Say bad human engineering idea.The trackerball basically saves much space.Disadvantage:
What is the function of a trackball?
A trackball is a pointing device consisting of a ball housed in a socket containing sensors to detect rotation of the ball about two axes-like an upside-down mouse with an exposed protruding ball. The user rolls the ball with the thumb, fingers, or the palm of the hand to move a cursor. Large tracker balls are common on CAD workstations for easy precision. Before the advent of the touchpad, small trackballs were common on portable computers, where there may be no desk space on which to run a mouse. Some small thumbballs clip onto the side of the keyboard and have integral buttons with the same function as mouse buttons. The trackball was invented by Tom Cranston and Fred Longstaff as part of the Royal Canadian Navy's DATAR system in 1952, eleven years before the mouse was invented. This first trackball used a Canadian five-pin bowling ball.
What is the difference between a mouse and a tackerball?
A mouse is a handheld device used to control a computer's cursor, typically featuring buttons and a scroll wheel, allowing for precise navigation and interaction with graphical user interfaces. A trackball, on the other hand, is a stationary input device that consists of a ball encased in a socket, which users rotate to move the cursor on the screen. While a mouse requires movement across a surface, a trackball remains in one place, making it beneficial for limited desk space or for users with certain mobility issues.
Is the most commonly used pointing device for personal computers?
Most laptops already have an alternative for a mouse. Some have a mouse pad or touchpad area. Moving a finger around in the touchpad works the same as moving a mouse. Others have a pointing stick in the keyboard, usually between the G H and B keys. It works like a little joy stick. There will also be some buttons below them that work as mouse buttons. Some alternatives to a mouse include a joy stick and a trackball. A trackball is like an upside down mouse where a ball is moved around by the hand. Some laptops also have touch sensitive screens (like an ipad or android) removing the need for a separate pointing device.
What are the advantages and disadvantages between an optical mouse and a ball mouse?
The laser of the optical mouse may bounce off certain colors and shapes on a mouse pad. * There are no disadvantages to a optical mouse. The optical mouse just works better and smoother than the ball mouse, and you never have to worry about the ball getting dirty or hanging. I would suggest getting an optical mouse and throwing the ball mouse away. For this you definitly need the opinion of someone who has to sufffer the ball mouse at least once a week. ie: School pupils. I have two IT lessons a fortnight, and at our school you have a choice between overly chunky optical mice or cheap, way too light ball mice. I end up tolerating the ball mice as I am very picky about my mice. I, personally like mice with a bit of weight on them, but the thick plastic outer of the school's optical mice is ridiculous. Generally, schools don't provide pupils with mousemats on the theory that they will be nicked/tooexpensive, so the only way to get the ball mice to operate in a friendly manner is to clean it before use, or use your science book as a substitute mousemat. The moral of this long-winded story is:
Working of trackball?
Trackballs are really upside-down, roller-bearing mice. Instead of the ball being inside the body, the ball is on the outside of a trackball and you move just the ball instead of the mouse body. Trackballs have several advantages over mice. Because you don't actually move the trackball itself, it takes up less space than a mouse does. And you don't have to lift it up to move it when you run out of room or reach. Because your hand remains stationary, you don't rub the sensitive areas of your wrist across the edge of your desk, which can lead to damage of the tissues in your forearm. Trackballs also have more than one button, and you can program the other buttons to perform various functions. For example, you can set a button to add a modifier key to the click so that you can bring up contextual menus with a click instead of having to hold down the Control key while you click. And trackballs can move the cursor either faster to cover more screen real estate or more slowly to give you more precise control than a mouse. Choosing a trackball is similar to choosing a keyboard or mouse (except that Macs don't ship with a "default" trackball). Look for one that fits your hand and has the features you want?such as the number of buttons it has.
Is a pointing device used by laying the palm of the hand over it and moving it across the surface of a pad that provides traction for a rolling ball on its bottom?
Yes, the description matches that of a trackball. Trackballs are input devices that allow users to move the cursor on a computer screen by rolling the ball with their fingers or palm while stationary. They are used as an alternative to traditional computer mice.
Where can customers purchase a mini HD camera?
One can purchase a mini HD camera in traditional brick and mortar stores such as Best Buy, Sears, Walmart and Target. One could also probably find cheaper prices at their online stores, or at websites such as Amazon, or eBay for second hand cameras.
Where can one find the book on the Logitech G7 Laser Cordless mouse?
One can find the book on the Logitech G7 Laser Cordless mouse at multiple sources online and in stores. The book is generally found with the mouse itself but can also be found at Logitech and from some second hand sellers, such as ebay.
What are the disadvantages of the trackball?
Disadvantages: A big disadvantage is that you are stuck with your hand in the same position well i wasnt actually sure of the disadvantages perhaps you can search it on Google ><"
