The United States is in an emerging period of transition, shifting to online multimedia campaigns. This research attempts to explore general knowledge of multimedia expansion, and through qualitative research methods provide a successful model for the development of an effective promotion tool. Findings from the heuristic study showed users preferences for varying forms of media, thus demonstrating the need to provide content in many different forms. The findings from this study aide in the development of multimedia, and illustrate the need for further studies in the use of multimedia as a promotion tool. / Department of Telecommunications

A common concern for people using computer databases is becoming "lost" within the complex hierarchy of entries. Most direct manipulation interface design guidelines suggest designers should include a feature for “undoing” user inputs (Smith and Mosier, 1986). In the case of a database, undo translates to backtracking support. The first purpose of this research was to confirm that computer-supported backtracking tools reduce navigation time over manual backtracking. The second purpose was to compare navigation times among a subset of backtracking tools. The third purpose was to determine if users prefer to use one or more backtracking tools significantly more than others. Four backtracking tools were developed by crossing two factors: History (history list vs no history list) and Level (component vs entry). History list indicates the user may view a chronological listing of nodes that have been viewed and directly select a destination node. No history list means the user must backtrack through each visited node with no shortcuts. Component indicates the backtracking tools operate only at the lowest level, or smallest definable node, of the tree-like database structure. Entry means that backtracking occurs at the higher parent node. Thus, multiple components make up an entry . In addition to the four computer backtracking tools, overall navigating and manual backtracking was done using a hierarchical Table of Contents. The tools were evaluated in an experimental, hierarchical, direct-manipulation database. Trials were conducted in the form of a multiple-choice information retrieval task. The independent variables included the backtracking tool (four-computer supported, one-manual) and the backtrack Task Length. The dependent measures included navigation time, the frequency with which the computer tool was used over manual backtracking (Table of Contents), and questionnaire responses. The results of this study provided some of the first solid support for the many guidelines that have been written recommending user recovery, or undo support. Backtracking with any of the four computer-supported tools resulted in a significantly smaller navigation time than manual backtracking using the Table of Contents. Subjects using either of the entry tools had consistent backtracking times across trials regardless of backtrack task length. When provided with a history list, subjects in the entry condition had significantly smaller navigation times than subjects in the component condition. Users did not show any differences between computer tools in rated efficiency, ease of use, or objective preference measures. / Master of Science

Title from PDF of title page. / Document formatted into pages; contains 97 pages. / Thesis (M.A.)--University of South Florida, 2003. / Includes bibliographical references. / Text (Electronic thesis) in PDF format. / ABSTRACT: Computer-based multimedia offer an alternative means of providing instruction to learners in two primary, yet disparate, ways. Multimedia can be used to convey information to learners, or alternatively, learners can make use of multimedia to impart information. One example of the use of multimedia technologies at the University of South Florida is an interactive computer kiosk installed in the Anthropology Exhibit Gallery. The development of the educational program featured on the kiosk's touchscreen computer is the subject of this paper. The purpose of the kiosk's program was twofold: 1) to introduce the field of anthropology to university students and the general public who visit the Anthropology Exhibit Gallery; and 2) to incorporate training in the creation of multimedia materials into two departmental project-based courses, Museum Methods and Visual Anthropology. / ABSTRACT: Designing effective educational programs that take advantage of multimedia capabilities without losing focus on the user's needs or on the content being presented is a challenging endeavor. In this paper, I present the process of designing an interactive multimedia program, and discuss the critical issues of audience, hardware and software, programming tools and other technical and design considerations. The development of the program, furthermore, must be understood within the broader context of several areas, including anthropology and museums, the role of education in museums, and exhibitions as a form of media and communication. Finally, a summary of the project is presented, including a discussion of the problems and successes encountered and suggested areas for further development. / System requirements: World Wide Web browser and PDF reader. / Mode of access: World Wide Web.
