The Ability Drive app has been updated. It has quite a few new features including different screen layouts, different button sizes and transparencies, and even the ability to turn on a gaze dot. The update can be downloaded from abilitydrive.app
We recently updated Ability Drive with many new customization settings such as choices for button positions, contrast, and size.
Ability Drive works on Tobii i-Series, Tolt Technologies A13, and SmartBox GridPad 12.
