Logitech Cordless TrackMan Wheel trackball mouse The original version of the Kensington Expert Mouse can use a standard American pool ball as a trackball. [citation needed]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.

A real estate license is an authorization issued by a government body to give agents and brokers the legal authority to represent a home seller or buyer in a real estate transaction. Real estate agents and real estate brokers are required to be licensed when conducting real estate transactions in the United States and in a small number of other ...
IntelliMouse Explorer 3.0 Microsoft IntelliMouse with IntelliEye optical sensor mouse. IntelliMouse is a series of computer mice from Microsoft.The IntelliMouse series is credited with a number of innovations; [1] Microsoft was among the first mouse vendors to introduce a scroll wheel, [2] an optical mouse, and dedicated auxiliary buttons on the side of the mouse.
The claim that the advent of optical tracking in mice put trackballs at a disadvantage makes no sense, as trackballs acquired optical tracking before mice. The first optical mouse (using the modern definition) was released in 1999 by Microsoft. The Logitech Trackman Marble used optical tracking and was released in 1996 — around 3 years earlier.
Optical pointing sticks are also used on some Ultrabook tablet hybrids, such as the Sony Duo 11, ThinkPad Tablet and Samsung Ativ Q. On the Gateway 2000 Liberty laptop the pointing stick is above the enter key on the right side of the keyboard. A pointing stick was featured in the New Nintendo 3DS as a secondary analog stick, known as the C-Stick.
Digital image correlation and tracking is an optical method that employs tracking and image registration techniques for accurate 2D and 3D measurements of changes in images. This method is often used to measure full-field displacement and strains , and it is widely applied in many areas of science and engineering.
For example, optical tracking can be the main tracking method, but when an occlusion occurs inertial tracking estimates the position until the objects are visible to the optical camera again. Inertial tracking could also generate position data in-between optical tracking position data because inertial tracking has higher update rate. Optical ...
In 1974 the City and County of Honolulu, Hawaii reported they were using an IBM 3886 to process motor vehicle and bicycle registration renewals, of which they received 400,000 annually. The 3886 scans the renewal forms at up to 5,000 forms an hour, storing them on tape, which is later played-back on their mainframe.
