Finally, a trackball designed for individuals with very large hands or very long fingers, with the added bonus of driverless programmability. This trackball features a large sculpted support on a long housing,
making it ideal for individuals with very large or long hands. All the buttons
are reprogrammable on board (i.e. within the hardware), allowing them to be
reconfigured on almost any platform without the need to install a driver.
For a select group of users, reducing fatigue is simply not enough. These people
often use a mouse continually for 8 or more hours at a time and require a device
which also eliminates the tiring motions which are caused by "double-click"
and "click and drag" applications. They require a device which saves
steps, reducing their physical stress. For these users, ITAC Systems presents
the Evolution Mouse-Trak. This is the most highly evolved trackball available
today. Designed for use in ergonomic workstations by the most demanding power
users.
The evolution MOUSE-TRAK has six keys, yet it works with standard two or three
button mouse drivers provided with your operating system. Each button is user
programmable without the use of proprietary drivers. ITAC could have made programming
easier by providing proprietary drivers, as some mouse/trackball manufacturers
have done. Their market research and experience have shown us that to do so
would create future driver support headaches for our users. Microsoft has a
long history of O/S upgrades which cause proprietary drivers to stop working
(along with the product supported by the driver.) ITAC has chosen to make programming
a bit tougher in order to assure its users that future support will be easier.
