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.
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.
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 ...
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.

Mouse tracking (also known as cursor tracking) is the use of software to collect users' mouse cursor positions on the computer. [1] This goal is to automatically gather richer information about what people are doing, typically to improve the design of an interface. Often this is done on the Web and can supplement eye tracking in some situations.
The success of Golden Tee 3D started a succession of yearly releases for the franchise, here the game illustrates its trackball-based controls.. The Golden Tee series began as a project at Incredible Technologies to create a large scale golf simulator for sizable family entertainment centers.
The Speedlite 420EX is an external flash formerly made by Canon. The Speedlite 420EX is one of Canon's older mid-range flashes, being replaced by the 430EX in 2005. It was primarily intended for users wanting to step up from the entry-level flashes, as well as for use as a slave flash along with the more advanced Speedlite 550EX flash.
