In addition, more sophisticated and detailed tools are available to teams and broadcasters that are not currently available to the public. [5] 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.
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.
Logitech Cordless TrackMan Wheel trackball mose 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.

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.
The problem with using eye tracking in usability testing is the required hardware and then expense. Additionally, eye tracking is limited to small sample sizes and abnormal browsing environments. Mouse tracking, on the other hand, is inexpensive and the data can be collected from any computer.

An early Xerox optical mouse chip, before the development of the inverted packaging design of Williams and Cherry. The first two optical mice, first demonstrated by two independent inventors in December 1980, had different basic designs: [1] [2] [3] One of these, invented by Steve Kirsch of MIT and Mouse Systems Corporation, [4] [5] used an infrared LED and a four-quadrant infrared sensor to ...
SportVU is a camera system that collects data 25 times per second. Its main objective is to follow the ball and all players on the court. [1] SportVU provides statistics such as real-time player and ball positioning through software and statistical algorithms.
