Icon Analysis

Designing the right icon from an HCI viewpoint ...

"An icon search task that lasts longer than anticipated can result in user annoyance or even premature abandonment. I once changed the mouse settings on my laptop to be overly sensitive, and had a colleague use it to show me a data analysis technique she had been working on. She immediately noticed and asked permission to change the settings. At my resolution of 1400×1050, the icons in the Windows control panel folder render at 16×16 pixels. In addition, I had the list pre-sorted by comment rather than application name. Not used to these settings or dealing with mouse preferences, she gave up the search for the mouse settings icon in seconds and opted to just use the ridiculously over-sensitive mouse while demonstrating her analysis technique.

You may think she was justified if only using my system for a short time. If so, you’d be surprised to know this was no small demo! It went on for almost a half an hour. She surfed the web to retrieve various files, used several applications, accessed her FTP space to download some of her own work, and showed the technique twice with different sets of user data. Scientist and user throughout, she sprinkled obscenities about the mouse amongst her thoughtful discussion of data analysis. I was astonished, and now far too afraid to tell her I had fooled with the mouse on purpose.

Two weeks later, I was discussing the analysis technique with another coworker and he said, “By the way, I heard your mouse is all messed up. I can fix that if you want.” Bad human computer interaction (HCI) experiences travel fast! The issue could have been avoided if only the mouse settings icon had been more identifiable."   (Continued via Boxes and Arrows)       [Usability Resources]
