Sorting a TV Stations Table
A Comparison of Three Methods for Sorting a TV Stations Table (Abstract)
Today a growing number of TVs and VCRs is provided with a comfortable function
which searches and stores channel numbers automatically on programme positions
and displays them in a "TV Stations Table". This function replaces the awkward
procedure of tuning the device step by step, but it causes the problem that users
must have the possibility to reorganize the list according to their own
preferences. In an experimental study we considered three different methods
(exchanging, shifting, and placing of elements) to sort such lists. The purpose
of the study was to to estimate the usability and likeability of the three
methods. A total of 108 subjects were randomly assigned to one of three
experimental conditions and asked to sort six word lists. Results suggest that
there are clear advantages of the sort method "exchange" over the other two
methods as well on measures of performance (time, buttons pressed, number of
change operations) as on measures of subjective preference. The conclusion is
drawn that the exchange of elements is better suited to sort TV station tables
then the two other methods.
