Toward a theory of music information retrieval queries: System design implications
(Working Paper, Department of Computer Science, University of Waikato, 2002) Cunningham, Sally Jo; Downie, J. Stephen
Interest in the development of content-based music information retrieval (MIR) systems is growing rapidly. The MIR research community consists of a multidisciplinary amalgam of librarians, digital librarians, information scientists, computer scientists, musicologists, audio engineers, lawyers and business persons. This multidisciplinary approach has given rise to significant technological advancements in retrieval algorithms, audio interfaces and data representation schemes. Notwithstanding these technological advancements, MIR research is currently a systems-centered research domain. For a variety of reasons-including intellectual property law, limited access to substantial, multigenre, multi-format collections and a lack of a historical user-base-MIR research has hitherto been unable to develop and exploit data concerning the nature of real-world user needs and use of music information.
Research laboratory survey
(Working Paper, University of Waikato, Department of Computer Science, 2002-11) Thomson, Kirsten
This report represents the results of a survey conducted by the University of Waikato Usability Laboratory of the research laboratories at the Department of Computer Science, The University of Waikato, Hamilton, New Zealand. The study was conducted on behalf of the Department of Computer Science. The goal of the research was to: Inform the development of future laboratories; Inform the process any of re-development of current laboratories; Provide information about the use and acceptance of the laboratories.
The LIDS Research Project: appendage to usability study report (1/2002)
(Working Paper, University of Waikato, Department of Computer Science, 2002-07) Thomson, Kirsten; McLeod, Laurie
This report is a follow on to an earlier report (titled: Usability Study Report (1/2002), dated 1 July 2002) that presented the University of Waikato Usability Laboratory’s (Usability Laboratory) analysis of the Large Interactive Display Screen (LIDS) technologies as developed by the LIDS Research Project.
Use of video shadow for small group interaction awareness on a large interactive display surface
(Working Paper, University of Waikato, Department of Computer Science, 2002-07) Apperley, Mark; McLeod, Laurie; Masoodian, Masood; Paine, Lance; Phillips, Malcolm; Rogers, Bill; Thomson, Kirsten
This paper reports work done as part of the Large Interactive Display Surface (LIDS) project at the University of Waikato. One application of the LIDS equipment is distributed meeting support. In this context large display surfaces are used as shared workspaces by people at collaborating sites. A meeting with start with a shared presentation document, typically and agenda document with summary and detail on agenda items as required. During the meeting, annotations with be made on the shared document, and new pages will be added with notes and drawings. To prevent access collisions and generally mediate use of the shared space, mechanisms to provide awareness of actions of people at other sites are required. In our system a web camera is used to capture a low-resolution image of the person/people near the board on each side. Rather than transmit the image directly we computed a shadow/silhouette. The shadow is displayed behind other screen content. This provides awareness of position and impending write actions and allows intentional pointing to locations of the screen. It also has the advantage of being transmitted with low bandwidth, being relatively insensitive to low frame rates, and minimizing visual interference with substantive data being displayed on the screen.
The LIDS Research Project: usability study report (1/2002)
(Working Paper, University of Waikato, Department of Computer Science, 2002-07) Thomson, Kirsten; McLeod, Laurie
This report represents the University of Waikato Usability Laboratory’s (Usability Laboratory) analysis of the Large Interactive Display Screen (LIDS) technologies as developed by the LIDS Research Group. The Usability Laboratory conducted three exploratory-type studies of the LIDS technology over January and February 2002. The studies each focused on individual elements of the LIDS technology, while at the same time contributing to the general understanding and knowledge of the technology.
