VIBROTACTILE GUIDANCE CUES FOR TARGET IDENTIFICATION
Title
VIBROTACTILE GUIDANCE CUES FOR TARGET IDENTIFICATION.
Creator
Downs, Joshua, Gilson, Richard, University of Central Florida
Abstract / Description
The purpose of this dissertation was to establish how vibrotactile guidance cues can be used to improve marksmanship. This work originated in an effort to provide covert communication, navigation, and weapon aiming cues for infantrymen. It is predominantly an application-driven investigation rather than driven a priori by specific theoretical predictions from models of human performance. Three experiments are presented. Experiment 1 established the affect on initial response to vibrotactile...
Show moreThe purpose of this dissertation was to establish how vibrotactile guidance cues can be used to improve marksmanship. This work originated in an effort to provide covert communication, navigation, and weapon aiming cues for infantrymen. It is predominantly an application-driven investigation rather than driven a priori by specific theoretical predictions from models of human performance. Three experiments are presented. Experiment 1 established the affect on initial response to vibrotactile guidance cues of tactor placements on the palmer versus dorsal surface of the hand, and targets appearing left versus right of center. Results suggest that tactile cues provided on the left side of the medial line of the hand afford moving the hand to the left, while tactile cues provided on the right side of the medial line afford moving the hand to the right. Experiment 2 established the affect of continuous relative distance cues and on- versus off-target vibrotactile stimuli on reaction time and accuracy for target selection. Results indicated an interaction between the pulse rate of vibrotactile stimuli and the method used to highlight an "on-target" condition; the suppressed target condition was superior to the enhanced target condition when the pulse rate increased as the cursor moved closer to a target. Experiment 3 established if there are performance differences between discrete and continuous distance information for target selection, and investigated the interaction between the near-target pulse rate and on-target cues. Results indicate that maximizing the difference between near-target guidance cues and on-target cues reduces the target selection time, particularly when the near-target pulse rates are fast (ISI = 10 msec). The results also suggest that, as with vision, the vibrotactile off-target guidance cues are not necessary during the whole target selection task. Rather, the guidance cues can be provided only during the initial pop-up condition and during the sub-movements closing on the target.

Show moreThe purpose of this thesis is to examine the Affordable Care Act through an analysis of the United States Supreme Court's holding in The National Federation of Independent Business v. Sebelius. In order to better understand the Supreme Court's reasoning in that case, this paper will first examine the history and the function of the Supreme Court, which will demonstrate the Court's power to either augment or diminish the power of the states in relation to the federal government. This paper will then discuss the background of the Affordable Care Act, the procedural history of the case, and the majority's analysis supporting its decision. The concurring and dissenting opinions of the other justices will be discussed to present the various viewpoints regarding the proper role of the federal government and the implications this case may have on federal/state conflict. The Supreme Court ruled in favor of the Department of Health and Human Services. The 5-4 decision was extremely close and the opinions given by each Justice highlighted the various flaws and benefits of the Act it was looking to uphold. Further research of Supreme Court cases in our country's history reveal the trend of augmenting and diminishing state's rights. This thesis will examine the constitutionality of the aforementioned decision, the effects it will have on each of the states within the United States, and the impact the citizens will experience.

Show moreHuman-computer interaction design principles largely focus on static representations and have yet to fully incorporate theories of perception appropriate for the dynamic multimodal interactions inherent to virtual environment (VE) interaction. Theories of direct perception, in particular affordance theory, may prove particularly relevant to enhancing VE interaction design. The present research constructs a conceptual model of how affordances are realized in the natural world and how lack of sensory stimuli may lead to realization failures in virtual environments. Implications of the model were empirically investigated by examining three affordances: passability, catchability, and flyability. The experimental design involved four factors for each of the three affordances and was implemented as a fractional factorial design. The results demonstrated that providing affording cues led to behavior closely in-line with real-world behavior. More specifically, when given affording cues participants tended to rotate their virtual bodies when entering narrow passageways, accurately judge balls as catchable, and fly when conditions warranted it. The results support the conceptual model and demonstrate 1) that substituting designed cues via sensory stimuli in available sensory modalities for absent or impoverished modalities may enable the perception of affordances in VEs; 2) that sensory stimuli substitutions provide potential approaches for enabling the perception of affordances in a VE which in the real world are cross-modal; and 3) that affordances relating to specific action capabilities may be enabled by designed sensory stimuli. This research lays an empirical foundation for a science of VE design based on choosing and implementing design properties so as to evoke targeted user behavior

Show moreThe Affordable Care Act is creating major political changes, on the state and federal levels, and is redefining American citizens' ability to access health services. Medical and mental health social workers are in high demand within the health care workforce to advocate and assist patients in navigating through a complex health care system. Little research has been conducted in understanding future social work professionals' views and knowledge about the legislation. This exploratory-descriptive study used a convenience sample of 105 Bachelors (BSW) and Masters (MSW) level social work students to explore views on health care policy and reform based on students' personal experiences accessing health care. The study also obtained an understanding of how demographic factors affect students' support for health reform. Implications of this study show the need for greater implementation of health policy education in the social work curriculum and further research on the factors affecting students' knowledge and attitudes of health reform.

Show moreThis study examined the association between different socio-demographic factors and food insecurity in the Central Florida Communities of Maitland, Winter Park, and Eatonville. Data from the Institute for Social and Behavioral Sciences at the University of Central Florida were utilized to analyze 3 main questions: In which community is food insecurity more prevalent? To what extent are food consumption, transportation, poverty, and unemployment associated with food insecurity? Does the association between food consumption, transportation, poverty, unemployment, and food insecurity remain when controlling for self-reported overall health, education, marital status, and race. The results revealed differences in predictors of food insecurities. Particularly, there was a positive relationship between food consumption and the knowledge of recommended number of servings of fruits and vegetables suggesting that those who have nutritional knowledge practice healthy dietary behaviors. Furthermore, structural dysfunctions and affordability pose food consumption limitations on the communities studied (mainly Eatonville).

Show moreOn March 23, 2010, President Barack Obama signed the Patient Protection and Affordable Care Act (PPACA) into law. This reform, it is argued, is projected to increase insurance coverage of pre-existing conditions, to expand access to insurance for more than 30 million Americans, and to increase estimated National medical spending while lowering projected Medicare spending. This thesis sought to investigate and analyze the perceptions of senior citizens in Central Florida about PPACA and their perceived effects on the healthcare quality provided to them under this law. Four sections of PPACA bill, thought to specifically pertain to the elderly, were selected for this study; respondents were asked their opinions regarding PPACA's aspects of: (1) the reform on preventive healthcare services; (2) Medicare Part D [prescription drugs]; (3) Medicare; and (4) Medicaid. This thesis employed both qualitative and quantitative methodologies; data were collected and analyzed with findings presented and discussed.

Show moreThe purpose of this study was to compare the academic achievement of sixth grade students enrolled in a traditional middle school model versus those enrolled in a K-8 school model by analyzing English Language Arts (ELA) and mathematics scores. Developmental Scale Score (DSS) data from the 2017 Florida Standards Assessment (FSA) were collected from three K-8 schools and three middle schools in one high-performing Florida school district. Results from an independent samples t-test revealed that middle school student scores were slightly higher in overall ELA and mathematics proficiency, but the differences were not substantive. Cross-tabulation was utilized to compute the proportion of students making learning gains in ELA and mathematics. The results were nearly identical among the middle school students and the K-8 students relative to ELA; however, the proportion of students making learning gains in mathematics was substantially higher among the K-8 students. To investigate equity in the distribution of achievement, a comparison was made between Middle School and K-8 bi-serial correlation coefficients measuring the strength and direction of the relationship between student achievement and socioeconomic status (SES). Results suggested that the negative influence of low-SES on academic achievement in ELA and mathematics was notably stronger among students enrolled in the middle school model. While making school construction decisions, policy makers will be informed through these findings as to which type of grade span configuration is most likely to positively impact student achievement.

Show moreFaculty have been identified as critical players in the implementation of textbook affordability efforts at community colleges. Furthermore, emerging lower-cost alternatives to traditional textbooks present a wide and growing range of options that may help further efforts. This study sought to examine more closely the role of faculty with respect to textbook cost-lowering initiatives. The researcher utilized in-depth interviews to gain a rich picture of the experiences, attitudes, beliefs, and behaviors of nine full-time community college faculty as they confronted textbook affordability efforts and textbook alternatives. The interview data were analyzed using a thematic analysis process. Five major themes and three minor themes were identified. The five major themes were: (a) campus administrators support, but do not mandate, efforts; (b) frequent edition revisions frustrate faculty; (c) departmental approaches to textbook selection vary; (d) content, then affordability, drive selection choices; and (e) faculty have mixed feelings about textbook alternatives. The three minor themes were: (a) faculty efforts to save students money are thwarted by campus bookstores and financial aid policies; (b) English faculty benefit from public domain readings; and (c) more faculty participating in textbook selection means more difficulty deciding on a text. Implications and recommendations were offered for community college leaders, campus bookstores, publishers, and future researchers.

Show moreThe three branches of government rely on public engagement for the prosperity of the nation. Moreover, informed public opinion is a fundamental tenant of democracy. With that in mind, this paper aims to explore the relationship between the Judicial Branch and the public. Specifically, this paper examines and questions the Supreme Court's efficacy communicating with the public. American constituents are inundated on a daily basis by the clamor of D.C. politics. The twenty four hour news cycle has given way to politicized headlines and exaggerated pundit commentary on contentious national issues. In a technological age where information is instant and the public has become accustomed to soundbites for education, the Supreme Court is left out of place. Both the Executive Branch and Legislative Branch converse directly with the public when necessary. Politicians frequently address their constituents or discuss complicated issues with voters first hand. However, the Supreme Court has rejected this strategy and instead relies almost exclusively on the press to relay their decisions. The judicial branch is the only third of our government without constant communication to the American people. As a result, the judiciary is relatively ignored by its citizens. By discussing a number of landmark cases since the turn of the century, this paper aims to analyze how those decisions were both announced to the public by the media and how the public received them. The Court has certainly adopted the press as an agent of communication. But is the media truly the proper outlet for the Court's rulings?
