Navigation and user flow design
•Use consistent navigation tools throughout an interface with extra and bolder navigation queues
–e.g. consistent navigation areas, bolded headings, etc.
•Avoid fly out dynamic menus
–e.g. those menus that appear and disappear depending on where the mouse is moved
•Group information into meaningful categories but do not use a deep hierarchy and limit the number of items in lists
–May seem hard to achieve - conflict of ideas?
•Avoid scroll bars or minimize the need for scrolling
–e.g. make web pages look like real pages
•Provide only one open window. Pop-ups or multiple overlapping windows should be avoided
•Provide redundancy in access to features
–e.g. redundant links, alternative methods of access, multi modal access, DTMF key presses that do the same as speech commands on a phone system
•Provide ample time to read information under time dependent constraints
–e.g. older people may need more time
