Testing Mozilla applications for Accessibility: Difference between revisions

*6. The scenario where a user has severe Motor Difficulties is matched to a Gnome environment that makes extensive use of switches, both 1 button and 2 button devices. The switches are used in conjunction with an on-screen keyboard (GOK, for one), to drive desktop operations. The input method used is row/cell scanning. This test scenario is more time-consuming compared with others, and it may be pragmatic to abbreviate some of the test cases. It is feasible to use a mouse without the ball to emulate the function of a switch. This user's mobility is severely restricted but can perform confirmation operations inside the on-screen keyboard application using a switch device. Switches might may come in such forms as a mouth-controlled sip+puff device, or a toggle switch mounted near the users head.
