Facilitating Heuristic Evaluation For Novice Evaluators, Anas Abulfaraj
Facilitating Heuristic Evaluation For Novice Evaluators, Anas Abulfaraj
College of Computing and Digital Media Dissertations
Heuristic evaluation (HE) is one of the most widely used usability evaluation methods. The reason for its popularity is that it is a discount method, meaning that it does not require substantial time or resources, and it is simple, as evaluators can evaluate a system guided by a set of usability heuristics. Despite its simplicity, a major problem with HE is that there is a significant gap in the quality of results produced by expert and novice evaluators. This gap has made some scholars question the usefulness of the method as they claim that the evaluation results are a product …
A Desire Fulfillment Theory Of Digital Game Enjoyment, Owen M. Schaffer
A Desire Fulfillment Theory Of Digital Game Enjoyment, Owen M. Schaffer
College of Computing and Digital Media Dissertations
Empirical research on what makes digital games enjoyable is critical for practitioners who want to design for enjoyment, including for Game Design, Gamification, and Serious Games. But existing theories of what leads to digital game enjoyment have been incomplete or lacking in empirical support showing their impact on enjoyment.
Desire Fulfillment Theory is proposed as a new theory of what leads to digital game enjoyment and tested through research with people who have recently played a digital game. This theory builds on three established theories: Expectancy Disconfirmation Theory, Theory of Basic Human Desires, and Flow Theory. These three theories are …
A Critical Analysis Of Mystery In Videogames, Ali Alkhafaji
A Critical Analysis Of Mystery In Videogames, Ali Alkhafaji
College of Computing and Digital Media Dissertations
Historically, videogame research has focused on how different videogame attributes (like challenge, fantasy, control, goals, etc.) impact the player experience. This type of research is important because it can provide insight into how to design more enjoyable videogames. However, very little exists within the current literature that focuses on mystery and its impact on the player experience. This dissertation is concerned with providing the research community with a better understanding of how mystery manifests in videogames and consequently impacts the player experience, specifically curiosity and motivation. To this end, the research questions are: 1. How do players experience mystery in …
Supporting Adult Learners' Metacognitive Development With A Sociotechnical System, Kathryn Wozniak
Supporting Adult Learners' Metacognitive Development With A Sociotechnical System, Kathryn Wozniak
College of Computing and Digital Media Dissertations
Metacognition is defined as thinking about and reflecting on one's cognitive processes. In learning contexts, strong metacognition leads to retention, academic success, and deep learning. While we know a lot about the metacognition of learners in grades K-12 and college, there are limited studies on adult learners' (24 and older) metacognitive awareness, how to support it, or the role technology can play, particularly since e-learning is quickly becoming the central mode of learning for adult learners. Thus, I have the following motivating research question: How can we support adult learners' metacognitive development in e-learning environments?
To better understand adult learners' …
The Effects Of Diagrams And Relational Complexity On User Performance In Conditional Probability Problems In A Non-Learning Context, Vincent J. Kellen
The Effects Of Diagrams And Relational Complexity On User Performance In Conditional Probability Problems In A Non-Learning Context, Vincent J. Kellen
College of Computing and Digital Media Dissertations
Many disciplines in everyday life depend on improved performance in conditional probability problems. Most adults struggle with conditional probability problems and several prior studies have shown participant accuracy is less than 50%. This study examined user performance when aided with computer-generated Venn and Euler type diagrams in a non-learning context. Despite the prevalence of research into diagrams and extensive research into conditional probability problem solving, this study is one of the only studies to apply theories of working memory to predict user performance in conditional probability problems with diagrams. Following relational complexity theory, this study manipulated problem complexity in computer …
A Representation Of Selected Nonmanual Signals In American Sign Language, Jerry C. Schnepp
A Representation Of Selected Nonmanual Signals In American Sign Language, Jerry C. Schnepp
College of Computing and Digital Media Dissertations
Computer-generated three-dimensional animation holds great promise for synthesizing utterances in American Sign Language (ASL) that are not only grammatical, but believable by members of the Deaf community. Animation poses several challenges stemming from the massive amounts of data necessary to specify the movement of three-dimensional geometry, and there is no current system that facilitates the synthesis of nonmanual signals. However, the linguistics of ASL can aid in surmounting the challenge by providing structure and rules for organizing the data.
This work presents a first method for representing ASL linguistic and extralinguistic processes that involve the face. Any such representation must …
