Ask UCD
At Library Connect presentations this summer some of you posed questions about usability. We've decided to include an “Ask UCD” column as a regular feature, so, if you have any burning usability issues you'd like answered please drop us a line at libraryconnect@elsevier.com. Chris Jasek of our User Centered Design (UCD) Group has agreed to answer them for you.
LC: Does data exist about users' reactions to pop-up screens? Academic libraries have to present more and more information on their Web pages. At the same time they are seeking to simplify this online environment to assist researchers and increase effective use of digital resources. Can pop-ups play a role here?
Jasek: In general I would not recommend popping open new browser windows as a way to simplify the user interface. New browser pop-ups can hurt usability because:
- Many users do not realize a new window has opened.
- The browser's “Back” button is disabled in the new window.
- Users are quickly frustrated by multiple windows cluttering the desktop.
- Users may automatically close pop-ups without reading them, thinking they are adverts.
Pop-ups can also affect accessibility as multiple browser windows are more complex for those using screen readers.
One good use for popping open a new browser window is a Help function. This keeps the context of the current page while providing the user assistance in a new window.
