Does anyone have any recommendations for designing a (non-web) application for use with a trackball instead of a mouse? If you know of any guidelines, standards or just your own experience in this area I would be grateful to hear from you!
So far I've gathered that pointer movement must be minimised, as the trackball is quite awkward to move - so I'm looking at moving / duplicating my navigation buttons so the pointer doesn't have to be moved further than necessary, and ensuring the user can use the keyboard as an alternative where possible.
(I know there are various trackballs out there and not all may be awkward, but I need to cater for specific existing hardware..)
