10/20/2003 1 Variations2 Usability Test v2.0 Report
I. Purpose of the Study
The Variations2: IU Digital Music Library project (V2) aims to establish a digital
music library testbed system that contains music in a variety of formats. The current
Variations system is used primarily by music students to listen to CD-quality
recordings online at computer workstations in the IU Cook Music Library.
This formative usability test examined Variations2, version 2.0, in preparation for its
release in September 2003. Goals of this test included:
Determine what problems users have when searching for selections
Determine what problems users have when accessing listening selections with
the audio player
Observe which methods of score viewing users prefer
Determine what problems users have when accessing, bookmarking and
printing scores
Judge whether score printing process was improved over v1.0
Determine what problems users have when accessing and manipulating the
timeline tool
Gauge user satisfaction with the timeline tool, in particular, use of computer-
based tools (vs. paper) to complete form diagramming tasks
Monitor problem areas to determine which need to be added to the help
pages
Gauge users’ levels of frustration and/or satisfaction with V2 as a whole.
Observe differences in interaction and usage patterns when users work with a
partner versus when users work individually.
Variations2 Components
Version 2.0 of Variations2 includes various components, most of which were present
in testing of version 1.0. However, some changes were made to these components
from v1.0 to v2.0. In addition, the timeline tool was not tested in the v1.0 round of
testing. Therefore, components used in this round of testing are illustrated below.
They include the search interface, audio player, score viewer, bookmarks editing
window, and timeline tool.
