Usability guru Jakob Nielsen released a study this week about mobile usability: http://www.useit.com/alertbox/mobile-usability.html.

The result? “The mobile user experience is miserable.”

Here are some highlights:

• The average success rate for mobile websites was 59% compared to 80% for regular sites.
• Small screens are limiting since they have to show less at a time which results in more clicks and a heavier reliance on short term memory.
• Input is awkward and more error prone due to more scrolling, tiny buttons and links, tiny keyboards, etc.
• Connections are still slow.
• Sites that have a mobile specific interface have a higher success rate (64%) compared to regular sites (53%).
• If a site has a mobile version, make it easy to find. Best technique is to auto-sense users’ devices and auto-forward mobile users to the mobile site. Additionally, make sure to include links to “mobile site” and “full site” to allow users to switch.
• Touch-screen phones perform better.

The new bad usability calendar is out for 2009.

Over at the del.icio.us blog, there’s a post about how they’ve noticed that librarians & educators are using delicious in interesting ways.

Over the past year or two, I’ve been delighted to notice educators and librarians embracing Delicious both as a way to share bookmarks with each other and a way to help their students and patrons learn. This makes perfect sense to me as a college student because I bookmark and tag references for all my projects and I’d love to see similar collections from my professors and classmates.

I don’t know who first realized the potential of Delicious for education, but I’ve seen a huge amount of community documentation created by teachers and librarians to help each other understand what this place is, why it’s valuable, and how to use it.
