Show moreComputers are increasingly a part of college and university instruction. Interactive hypermedia applications are being introduced throughout much of the curriculum as a possible solution to both improving educational outcomes and expanding educational horizons. The purpose of the present study was to investigate the effects of an interactive hypermedia application and a section of text on a measure of learning and understanding called concept mapping. The inter-rater reliability of concept map scores has not been reported previously in the literature. Results in this study concerning the reliability of concept map scoring procedures indicated that the continued improvement of inter-rater reliability is desirable if concept mapping is to actualize its potential as a practical, useful, and unique learning tool. Results suggest that concept mapping appears capable of assessing: (a) baseline knowledge, (b) meaningful learning, (c) the construction of new knowledge, and (d) knowledge change. Its usefulness in these areas and as an alternative or addition to standardized assessment is contingent, however, upon demonstrations of validity and reliability. Suggestions for further concept map research included: (a) replicating the present study with other measures of cognitive style across a wide variety of interactive hypermedia software applications, (b) doing longitudinal studies of concept mapping, (c) improving the reliablity of concept map scoring and evaluation, (d) looking at other aspects of cognition and information processing related to concept mapping, (e) using computer-based concept mapping tools, and (f) using concept maps as templates for the organization and integration of hypermedia elements.

Creator
Carmigniani, Julie., Charles E. Schmidt College of Science, Department of Computer and Electrical Engineering and Computer Science
Abstract/Description
While new technologies are often used to facilitate regular people's lives, they often fail to see their potential in helping disabled people. Augmented reality, one of the newest state-of-the-art technologies, offers users the opportunity to add virtual information to their real world surroundings in real time. It also has the potential to not only augment the sense of sight, but also other senses such as hearing. Augmented reality could be used to offer the opportunity to complement users'...
Show moreWhile new technologies are often used to facilitate regular people's lives, they often fail to see their potential in helping disabled people. Augmented reality, one of the newest state-of-the-art technologies, offers users the opportunity to add virtual information to their real world surroundings in real time. It also has the potential to not only augment the sense of sight, but also other senses such as hearing. Augmented reality could be used to offer the opportunity to complement users' missing sense. In this thesis, we study augmented reality technologies, systems and applications, and suggest the future of AR applications. We explain how to integrate augmented reality into iOS applications and propose an augmented reality application for hearing augmentation using an iPad2. We believe mobile devices are the best platform for augmented reality as they are widespread and their computational power is rapidly growing to be able to handle true AR applications.

It is becoming increasingly important for an autonomous system to be able to explain its actions to humans in order to improve trust and enhance human-machine collaboration. However, providing the most appropriate kind of explanations – in terms of length, format, and presentation mode of explanations at the proper time – is critical to enhancing their effectiveness.

Show moreIt is becoming increasingly important for an autonomous system to be able to explain its actions to humans in order to improve trust and enhance human-machine collaboration. However, providing the most appropriate kind of explanations – in terms of length, format, and presentation mode of explanations at the proper time – is critical to enhancing their effectiveness. Explanation entails costs, such as the time it takes to explain and for humans to comprehend and respond. Therefore, the actual improvement in human-system tasks from explanations (if any) is not always obvious, particularly given various forms of uncertainty in knowledge about humans. In this research, we propose an approach to address this issue. The key idea is to provide a structured framework that allows a system to model and reason about human personality traits as critical elements to guide proper explanation in human and system collaboration. In particular, we focus on the two concerns of modality and amount of explanation in order to optimize the explanation experience and improve overall system-human utility. Our models are based on probabilistic modeling and analysis (PRISM-games) to determine at run time what the most effective explanation under uncertainty is. To demonstrate our approach, we introduce a self-adaptative system called Grid – a virtual game – and the Stock Prediction Engine (SPE), which allows an automated system and a human to collaborate on the game and stock investments. Our evaluation of these exemplars, through simulation, demonstrates that a human subject’s performance and overall human-system utility is improved when considering the psychology of human personality traits in providing explanations.

Show moreThe purpose of this mixed methods study was twofold. First, the study assessed whether Davis’ (1989) Technology Acceptance Model (TAM) was useful in predicting instructional usage of the interactive whiteboard (IWB), as reported by K-8 teachers. Second, the study set out to understand what motivated those teachers to use the IWB for classroom instruction, and to further describe the ways in which they used them. Through surveying 155 teachers and 40 administrators of the Lutheran Church Missouri Synod (LCMS) schools, the researcher used multiple regression and moderator analyses to examine whether the TAM model helped explain teachers’ reported teacher-centered and student-centered instructional IWB usage. The researcher followed this by oneon- one interviews with 5 of the teachers surveyed. With the data gathered from the interviews and open-ended items from the original surveys, an analysis using qualitative methods was performed. The results from the qualitative analysis were then used to help refine and explain the quantitative findings. The results of the study’s quantitative phase indicated two variables adapted from the TAM, teachers’ perceived usefulness and perceived ease of use of the IWB, contributed to the prediction of teacher-centered instructional usage of the device. Further it was found that the perceived usefulness variable contributed to the prediction of student-centered instructional usage. Moderator analysis indicated the variable for teachers’ IWB technological pedagogical content knowledge, adapted from Mishra and Koehler’s (2006) technological pedagogical content knowledge framework, moderated the relationships between the variable perceived ease of use of the IWB and teacher and student-centered instructional usage respectively, as well as between the variable perceived usefulness of the IWB and teacher-centered instructional usage. The qualitative phase results revealed those teachers surveyed used their IWBs in a variety of ways for both teacher-centered and student-centered instruction. Teachers frequently reported they were motivated to use the device by its overall user-friendliness and its utility as an instructional tool. Central to the teachers’ discussion of its utility were ways in which the tool positively impacted the students during instruction. Specifically how it engaged students by attracting their attention, keeping them focused, and offering them a better way to learn.

Show moreA self-adaptive software is developed to predict the stock market. It’s Stock Prediction Engine functions autonomously when its skill-set suffices to achieve its goal, and it includes human-in-the-loop when it recognizes conditions benefiting from more complex, expert human intervention. Key to the system is a module that decides of human participation. It works by monitoring three mental states unobtrusively and in real time with Electroencephalography (EEG). The mental states are drawn from the Opportunity-Willingness-Capability (OWC) model. This research demonstrates that the three mental states are predictive of whether the Human Computer Interaction System functions better autonomously (human with low scores on opportunity and/or willingness, capability) or with the human-in-the-loop, with willingness carrying the largest predictive power. This transdisciplinary software engineering research exemplifies the next step of self-adaptive systems in which human and computer benefit from optimized autonomous and cooperative interactions, and in which neural inputs allow for unobtrusive pre-interactions.

Abstract/Description
With the exponential increase of Internet usage and the embedding of multimedia content on the Web, some of the Internet resources remain inaccessible for people with disabilities. Particularly, people who are deaf or Hard of Hearing (HOH) experience inaccessible Web sites due to a lack of Closed Captioning (CC) for multimedia content on the Web, no sign language equivalents for the content on the Web, and an insufficient evaluation framework for determining if a Web page is accessible to the...
Show moreWith the exponential increase of Internet usage and the embedding of multimedia content on the Web, some of the Internet resources remain inaccessible for people with disabilities. Particularly, people who are deaf or Hard of Hearing (HOH) experience inaccessible Web sites due to a lack of Closed Captioning (CC) for multimedia content on the Web, no sign language equivalents for the content on the Web, and an insufficient evaluation framework for determining if a Web page is accessible to the Hearing Impaired community. Several opportunities for accessing content needed to be rectified in order for the Hearing Impaired community to access the full benefits of the information repository on the Internet. The research contributions of this thesis are to resolve some of the Web accessibility problems being faced by the Hearing Impaired community. These objectives are to create an automated CC for the Web for multimedia content, to embed sign language equivalent for content available on the Web, to create a framework to evaluate Web accessibility for the Hearing Impaired community, and to create a social network for the Deaf community. To demonstrate the feasibility of fulfilling the above listed objectives several prototypes were implemented. These prototypes have been used in real life scenarios in order to have an objective evaluation of the proposed framework. Further, the implemented prototypes have had an impact to both the academic community and to the industry.

Show moreHow we share our good news with people can have a significant effect on our lives. Sharing good news on social media sites involves a process called capitalization. Capitalization has been shown to increase well-being when others provide appropriate responses in face-to-face interactions. To see if this effect on well-being extends to our online presence, this study utilized the social media site Facebook to observe if capitalization predicted well-being and relationship satisfaction. This study used data collected from 137 participants recruited from an undergraduate participant pool and from Amazon Mechanical Turk. Consistent with hypotheses, participants who reported receiving active and constructive responses after sharing a positive event on Facebook also reported greater personal well-being and relationship satisfaction. Although future experimental research is needed to establish causality, the current results suggest that the ways in which friends respond to social media posts are associated with personal and relationship well-being.
