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 buttonsare reprogrammable on board (i.e. within the hardware), allowing them to bereconfigured on almost any platform without the need to install a driver.
For a select group of users, reducing fatigue is simply not enough. These peopleoften use a mouse continually for 8 or more hours at a time and require a devicewhich also eliminates the tiring motions which are caused by "double-click"and "click and drag" applications. They require a device which savessteps, reducing their physical stress. For these users, ITAC Systems presentsthe Evolution Mouse-Trak. This is the most highly evolved trackball availabletoday. Designed for use in ergonomic workstations by the most demanding powerusers.
The evolution MOUSE-TRAK has six keys, yet it works with standard two or threebutton mouse drivers provided with your operating system. Each button is userprogrammable without the use of proprietary drivers. ITAC could have made programmingeasier by providing proprietary drivers, as some mouse/trackball manufacturershave done. Their market research and experience have shown us that to do sowould create future driver support headaches for our users. Microsoft has along 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 programminga bit tougher in order to assure its users that future support will be easier.
