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.

Player tracking systems introduce many new statistics, automate the collection of data and provide precision which would be impossible without the use of camera technology and tracking software. Statistics collected, and available to view during the game and throughout the season include (all statistics are per player): [ 6 ]
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.
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.
SportVU converted their tracking system from delayed processing to real-time data delivery during the 2011-2012 NBA season. [12] At the start of the 2012-2013 season, 10 teams were using SportVU. [11] Since the 2013-2014 NBA season, the SportVU camera system was installed in all NBA arenas. [13]
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 ...
The 2022 Pac-12 Track & Field Championships were not even two full years ago, but for Elliott Cook, it feels like a lifetime. The Oregon junior, who won the men’s 800-meter title that season, is ...
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.
