Requiring no hand or wrist movement, Orbitrack represents a significant advance in computer input technology and is suitable for computer users with motor skill difficulties and movement impairment. Unlike a mouse, trackball or joystick, no hand or wrist movement is necessary and unlike a touch pad, the cursor does not have to be ‘driven’ around the screen by constant finger movement.
This makes the unit perfect for users with conditions such as Muscular Dystrophy, Motor Neurone Disease, Carpal Tunnel Syndrome or indeed any condition that results in forearm strength issues.
The central white ‘dot’ inside the touch-ring is a finger rest and when touched, does not result in cursor movement. However, when the user moves his/her finger onto the touch-ring, the cursor moves in the direction indicated by the finger’s position on the ring. In other words, to move the cursor into the top right corner of the screen, touch the grey ring at the 2 o’clock position. Cursor movement will continue until the finger is either removed or moved back to the central white dot.
Concentric touch-sensitive buttons are provided for left click, right click, double-click and drag, which may be turned off in favour of external switches.. As with all other Pretorian mouse alternatives, Orbitrack is switch adapted (left and right click), has cursor speed settings and doesn’t require a driver be loaded on the host computer.
Orbitrack also has a unique SmartTrack facility, which calculates the speed of the cursor according to recent movements, i.e. it ‘learns’ what you are doing and works out the optimum speed setting for you.
