Mouse Rolling

Trackball - Wikipedia

en.wikipedia.org

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. With an LED for illumination from one side and an optical sensor on the other, rotation of the wheel periodically blocks and unblocks the light, so the sensor produces electrical pulses to indicate that rotation is occurring. Mice used the same basic system for determining motion, but had the problem that the ball was in contact with the desk or mousepad. In order to provide smooth motion the balls were often covered with an anti-slip surface treatment, which was, by design, sticky. Rolling the mouse tended to pick up any dirt and drag it into the system where it would clog the chopper wheels, demanding cleanup. With most trackballs, operators have to lift their finger, thumb or hand and reposition it on the ball to continue rolling, whereas a mouse would have to be lifted itself and re-positioned. Some trackballs have notably low friction, as well as being made of a dense material such as phenolic resin, so they can be spun to make them coast. This trackball was called Rollkugel (German for "rolling ball"). Somewhat later, the idea of "reversing" this device led to the introduction of the first computer ball mouse (still named Rollkugel, model RKS 100-86), which was offered as an alternative input device to light pens and trackballs for Telefunken's computer systems since 1968. Benjamin felt that a more elegant input device was needed and invented a ball tracker system called the roller ball for this purpose in 1946. The device was patented in 1947, but only a prototype using a metal ball rolling on two rubber-coated wheels was ever built and the device was kept as a military secret. Production versions of the CDS used joysticks.

Scroll wheel - Wikipedia

Some user interfaces, like Cinnamon, allow using it to adjust brightness and volume by pointing at the respective taskbar icon and rolling the wheel. Spinners and drop-down lists in most toolkits also allow adjustment of the value using mouse wheel. The scroll wheel on a mouse has been invented multiple times by different people unaware of the others' work. Other scrolling controls on a mouse, and the use of a wheel for scrolling both precede the combination of wheel and mouse. The earliest known example of the former is the Mighty Mouse prototype developed jointly by NTT, Japan and ETH Zürich, Switzerland (Kunio Ōno, Ken'ichi Fukaya and Jürg Nievergelt) in 1985. rolling the wheel from the top side to the bottom, is known as scrolling "downward" or "backward". In a graphical user interface, the "upward" motion moves contents of the window downward (and the scrollbar thumb, if present, upward), and vice versa. In other configurations (sometimes called "natural scrolling") the effect is inverted. On most mice, the scroll wheel can often also be used as a third, middle mouse button by pressing down on it, known as the scroll button. A scroll wheel is a wheel used for scrolling on an electronic visual display. The term usually refers to a wheel found on a computer mouse, in which case it is also called a mouse wheel. It is often made of hard plastic with a rubbery surface, centred around an internal rotary encoder. Some mice's scroll wheels can scroll horizontally by tilting them to the left or right, or there may be additional wheel on a perpendicular axis located elsewhere on the mouse. The wheel is often, but not always, engineered with detents to turn in discrete steps, rather than continuously as an analog axis, to allow the operator to more easily intuit how far they are scrolling.

The RollerMouse Red replaces your traditional mouse with a centered "roller bar" designed to reduce shoulder and wrist strain. For heavy typists or office workers dealing with discomfort, it could be a game-changer, but it's expensive. The RollerMouse Red (starts at $374) is a striking device. Instead of sitting off to the side of your keyboard like a traditional computer mouse does, this input tool lives directly in front of it, where your wrist rest would normally go. The signature feature is a 7-inch roller bar that tracks horizontal movement and acts as a clickable button. The roller bar glides effortlessly, and once you dial in your preferred DPI setting, it's easy to control across single- or dual-monitor setups. However, the device is not well-suited for precision work. We found it difficult to control fine cursor movement in Photoshop, Illustrator, and similar apps. If your daily workflow includes design, CAD, or gaming, this won't replace your go-to mouse.
