Usability Review of KBruch

Saturday, 22 October 2005  |  Seele

This weekend I finally finished writing my review for KBruch. KBruch is an Edutainment application which allows students to practice fractions. It has several modes of operation: Evaluation of multiple terms, Factorization of numbers, Comparison between two terms, and Conversion to decimal.

Overall I was impressed with the application, its variety of task modes allow users to cover all necessary basics to gain a good understanding for fractions. (Basically if I had kids, I'd make them use this ;))

Most of the issues were minor to moderate, usually having to do with size, position, or labeling of an item. There were a few severe issues I was concerned about which could seriously effect game-play, but no changes were so serious that it would be very difficult to fix. I also provided some interface suggestions on how some of the usability issues could be fixed.

There was one concern I had about the interface I am not completely sure how to fix. In the old interface, the mode buttons were along the left in a menu, similar to other KDE interfaces (such as Control Center). The concern was the layout of the interface (which was in 3 columns) and the obscurity of the mode options in the toolbar (difficult to interpret immediately, always available even when not in use). There may be a better solution than putting the modes in the toolbar, and I am open for suggestions.

I love working with the Edutainment packages, because children are a very peculiar audience. More freedom is given in the interface to include color, graphics, and sounds to make them more engaging for younger users. Children are also a challenge to design for because they have special needs in regards to language, context, font size, etc.
