The n-ABLER Pro Trackball is specifically designed for computer users with limited hand control, motor skill difficulties, poor hand-eye-coordination, limited manual dexterity, involuntary muscle spasms and hand or wrist tremors.
n-ABLER Pro was introduced to satisfy the needs of older users. Pretorian observed that teenage and ageing users were reluctant to use n-ABLER as they associate the brightly coloured buttons with children’s products, yet their needs are in many ways similar to younger users.
In answer to this, n-ABLER Pro was launched. It has a modern silver over- black colour scheme and black buttons with white legends, which are great for users with visual impairments.
Because ageing users can sometimes exhibit tremors, a unique anti-tremor facility was built in which filters out the tremors, leaving the underlying movement of the joystick or trackball. There are four selectable levels of anti-tremor filtering, and the feature may be turned off for users who have no need of it.
Dwell Clicker is a new feature recently incorporated into n-ABLER Pro, allowing users to achieve completely switch-free selection of items on screen. Simply allow the cursor to dwell over the item in question for a pre-determined (but selectable) period and n-ABLER Pro will click it for you!
Of course, all the great features that you already associate with n-ABLER such as cursor speed settings, drag-lock, double-click, programmable switch adaptation and driver-free operation are still available in n-ABLER Pro.
