I am working on an online application that explores the anatomy of certain
In one section, we have a cross-cut diagram of a body part (the eye). Next
to it is a list of its subparts (macula, retina, cornea, etc.).
Originally, it was intended that when any of these items was clicked, that
would launch a highlight on the subpart, a voice over, and a text box
explaining what the part is and does.
The graphic designer added a roll-over function, which would highlight the
subpart as each item is rolled over.
The problem is obvious: if we are clicked into an item, reading the text and
listening to the vo, should the user be able to continue to roll over other
items in the list? If so, how should that roll over be distinguished from
the item we are clicked into? If the user is locked out of rolling over, how
do you restore this function after the user is finished learning about the
subpart (if he clicks into another item, he is still not in rollover mode).
If this is not sufficiently confusing, I can probably make it more so. :-)
Any ideas or best practices suggestions I can return to my team with?
