The n-ABLER Trackball is especially suitable for improving access for children and young people with some special educational needs, learning difficulties, for those who’s work entails long periods of computer use and for older people and others with movement impairment.
The large, high mass, free running ball requires only a light touch which, together with the function buttons, makes for easy navigation, selection and manipulation of objects on the computer screen.
The n-ABLER Trackball emulates a computer mouse but, with fingertip control and the need for only minimal hand movement, reduces wrist and elbow fatigue, requires far less effort and is less tiring. The symmetrical design enables users to work with either hand without having to angle the wrist, and the unit can also be configured for ‘left-handed’ operation. Its large, integrated hand support/palm rest makes work posture more relaxed and less strained.
For users with limited movement, double-clicking and click-anddrag can be particularly difficult- so n-ABLER provides buttons to perform these actions for you.
The cursor speed may be selected using a button on the rear of the unit which, together with the single-axis button, can be used to tailor the cursor movement to the user’s exact needs.
n-ABLER is switch adapted and the two 3.5mm sockets provided can be programmed to function as any of the six built-in buttons (including speed).
Building on the huge success of n-ABLER, n-ABLER Pro was introduced to satisfy the needs of older users. We observed that once users became teenagers, they would tend not to want to use n-ABLER since they associate the brightly coloured buttons with children’s products. Similarly, ageing users generally did not want to use a product which was clearly meant for children, yet their needs are in many ways similar to younger users.
In answer to this, we launched n-ABLER Pro. It has a modern silverover- black colour scheme and black buttons with white legends, which are great for users with visual impairments.
Because ageing users can sometimes exhibit tremors, we also built in a unique anti-tremor facility 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
