Comparative Examination Of The Empatica E4 To Record Heart Rate Variability Metrics, Andres Rosero
Comparative Examination Of The Empatica E4 To Record Heart Rate Variability Metrics, Andres Rosero
Honors Undergraduate Theses
The increased accessibility of cyber technology has resulted in advancements in international communications and information sharing never seen in human history. With this new age of digital software comes the proliferation of illegal online activity and cyber terrorism. Repercussions of cyber-attacks have ranged from identity theft to leaks of classified state secrets. To combat this threat, the Department of Defense (DoD) established the Cyber Mission Force (CMF) to head operations in the interests of protecting against cyber-attacks. One of the CMF’s initial projects involves the creation of a Performance Assessment Suite (PAS), a training program designed to improve the training …
Assessment Of Instructional Presentation For Emergency Evacuation Assistive Technology, Michael Boyce
Assessment Of Instructional Presentation For Emergency Evacuation Assistive Technology, Michael Boyce
Electronic Theses and Dissertations
It is often the case that emergency first responders are well equipped and trained to deal with a situation that involves evacuation of someone with a physical disability. However, emergency responders are not always the first line of defense, or they may be otherwise occupied with assisting others. This research examined the effects of instructions for emergency stair travel devices on untrained or novice users. It was hypothesized that through redesign of the evacuation instructions, untrained individuals would be able to successfully prepare an evacuation chair and secure someone with a disability more effectively and efficiently. A prepost study design …
The Effects Of Multimodal Feedback And Age On A Mouse Pointing Task, Brian Oakley
The Effects Of Multimodal Feedback And Age On A Mouse Pointing Task, Brian Oakley
Electronic Theses and Dissertations
As the beneficial aspects of computers become more apparent to the elderly population and the baby boom generation moves into later adulthood there is opportunity to increase performance for older computer users. Performance decrements that occur naturally to the motor skills of older adults have shown to have a negative effect on interactions with indirect-manipulation devices, such as computer mice (Murata & Iwase, 2005). Although, a mouse will always have the traits of an indirect-manipulation interaction, the inclusion of additional sensory feedback likely increases the saliency of the task to the real world resulting in increases in performance (Biocca et …
Emotional Evaluation Of A Product/System, Hana Smith
Emotional Evaluation Of A Product/System, Hana Smith
Electronic Theses and Dissertations
Technological advances in products and systems have brought emotional design or emotional engineering to the forefront of research. While several measures to assess emotional expression of products have been developed, the source of the emotion rating of a product or system was often unclear. The purpose of this dissertation is to conduct three studies to examine the causes of emotional ratings and to establish if product-specific emotion rating scales are useful for capturing accurate user evaluations. Three studies were conducted using citrus juicers. Juicers were chosen for several reasons: their wide variety of styles, one self-explanatory purpose (to make juice), …
Does Safety Culture Predict Clinical Outcomes?, Katherine Ann Wilson
Does Safety Culture Predict Clinical Outcomes?, Katherine Ann Wilson
Electronic Theses and Dissertations
Patient safety in healthcare has become a national objective. Healthcare organizations are striving to improve patient safety and have turned to high reliability organizations as those in which to model. One initiative taken on by healthcare is improving patient safety culture--shifting from one of a 'no harm, no foul' to a culture of learning that encourages the reporting of errors, even those in which patient harm does not occur. Lacking from the literature, however, is an understanding of how safety culture impacts outcomes. While there has been some research done in this area, and safety culture is argued to have …
Friend/Foe Identification Accuracy And Shooting Performance: Effects Of Prior Task Loading And Time Pressure, Kelly Ann Burke
Friend/Foe Identification Accuracy And Shooting Performance: Effects Of Prior Task Loading And Time Pressure, Kelly Ann Burke
Electronic Theses and Dissertations
The current dismounted soldier and the soldier of the future will be "loaded" with more information processing tasks while they perform shooting tasks. It is conceivable that some increased level of cognitive tasking may be performed simultaneously with required shooting tasks. The effect of cognitive load on shooting performance has been previously examined (Scribner and Harper, 2001). This study concentrated on the effect of various cognitive workload demands on a friend-foe discrimination shooting task in a single- and dual-task scenario. In light of this, it is imperative that the soldier not be overburdened mentally, which may result in decreased survivability …
Accidental Inversion During 3d Rotation With 2-Dof Input Devices, Derek Daniel Diaz
Accidental Inversion During 3d Rotation With 2-Dof Input Devices, Derek Daniel Diaz
Electronic Theses and Dissertations
This dissertation focuses on a human operator's ability to perform rotational control of a three-dimensional object using two-degrees of freedom (DOF) interface devices. Although input devices designed specifically for 3D interaction exist, devices traditionally used for two-dimensional user interaction, such as a mouse or joystick, have become ubiquitous to computer tasks. This research examines a particular human-computer interaction issue that arises from stimulus-response compatibility between three-dimensional stimuli spaces and 2-DOF response sets. The focal point of this research is a phenomenon referred to here as accidental inversion. Accidental inversions occur when an operator erroneously moves a three-dimensional object in a …
Training Wayfinding: Natural Movement In Mixed Reality, Ruthann Savage
Training Wayfinding: Natural Movement In Mixed Reality, Ruthann Savage
Electronic Theses and Dissertations
The Army needs a distributed training environment that can be accessed whenever and wherever required for training and mission rehearsal. This paper describes an exploratory experiment designed to investigate the effectiveness of a prototype of such a system in training a navigation task. A wearable computer, acoustic tracking system, and see-through head mounted display (HMD) were used to wirelessly track users' head position and orientation while presenting a graphic representation of their virtual surroundings, through which the user walked using natural movement. As previous studies have shown that virtual environments can be used to train navigation, the ability to add …
Orienting Of Visual-Spatial Attention With Augmented Reality: Effects Of Spatial And Non-Spatial Multi-Modal Cues, Christian Jerome
Orienting Of Visual-Spatial Attention With Augmented Reality: Effects Of Spatial And Non-Spatial Multi-Modal Cues, Christian Jerome
Electronic Theses and Dissertations
Advances in simulation technology have brought about many improvements to the way we train tasks, as well as how we perform tasks in the operational field. Augmented reality (AR) is an example of how to enhance the user's experience in the real world with computer generated information and graphics. Visual search tasks are known to be capacity demanding and therefore may be improved by training in an AR environment. During the experimental task, participants searched for enemies (while cued from visual, auditory, tactile, combinations of two, or all three modality cues) and tried to shoot them while avoiding shooting the …
Warning Compliance: Effects Of Stress And Working Memory, Jessica Helmick-Rich
Warning Compliance: Effects Of Stress And Working Memory, Jessica Helmick-Rich
Electronic Theses and Dissertations
This study investigated the effects of cross-modality warning presentation and retention in a dual-task paradigm in a simulated military environment under various task-induced stress levels. It was also intended to determine what role working memory played in the mode of warning presentation that resulted in the highest retention and subsequent compliance. An all within participant design was created in order to determine if scores on working memory span tasks predicted performance across the varying forms of warning presentation. Furthermore, task-induced stress levels were varied over the course of the experiment to identify if workload transitions affected performance. Results revealed that …
