A gendered, three-dimensional, animated, human-like character accompanied by text- and speech-based dialogue visually represented the proposed affective agent. The agent’s pedagogical interventions considered inputs from the ELE (interface, model building, and performance events) and from the user (emotional and cognitive events). The user’s emotional events captured by biometric sensors and processed by a decision-level fusion algorithm for a multimodal system in combination with the events from the ELE informed the production-rule-based behavior engine to define and trigger pedagogical interventions. The pedagogical interventions were focused on affective dimensions and occurred in the form of affective dialogue prompts and animations.
An experiment was conducted to assess the impact of the affective agent, Hope, on the student’s learning experience and performance. In terms of the student’s learning experience, the effect of the agent was analyzed in four components: perception of the instructional material, perception of the usefulness of the agent, ELE usability, and the affective responses from the agent triggered by the student’s affective states.
Additionally, in terms of the student’s performance, the effect of the agent was analyzed in five components: tasks completed, time spent solving a task, planning time while solving a task, usage of the provided help, and attempts to successfully complete a task. The findings from the experiment did not provide the anticipated results related to the effect of the agent; however, the results provided insights to improve diverse components in the design of affective agents as well as for the design of the behavior engines and algorithms to detect, represent, and handle affective information.
Consumer automotive vehicles have been an essential part of daily life for many over several decades. Many people also find that the multimedia screens found in the center consoles of many modern vehicles are robust enough to complete a certain number of tasks, such as navigating to a destination, playing music, or taking a phone call. As a result, it is important for designers to look into their decisions and how they might affect the overall experience a person has while interacting with multimedia screen as they are driving a vehicle. This study aims to look into how existing design decisions present themselves in the multimedia screens of modern vehicles and which principles of design users favor when interacting with the systems. With 188 participants and three vehicles tested, including the 2019 Toyota Highlander equipped with native software, the 2019 Hyundai Sonata equipped with Android Auto, and the 2020 Hyundai Elantra equipped with Apple CarPlay, it was found that design principles found in Human Computer Interaction, such as Gestalt principles, are relevant in allowing for a more positive, enjoyable experience in completing tasks such as navigation, playing music, and taking a phone call.
This thesis explores how large scale cyber exercises work in the 21st century, going in-depth on Exercise Cyber Shield, the Department of Defense’s largest unclassified cyber defense exercise run by the Army National Guard. It highlights why these cyber exercises are so relevant, going over several large scale cyber attacks that have occurred in the past year and the impact they caused. This research aims to illuminate the intricacies around cyber exercise assessment involving manual vs automated scoring systems; this is brought back to work on creating an automated scoring engine for Exercise Cyber Shield. This thesis provides an inside look behind the scenes of the operations of the largest unclassified cyber defense exercise in the United States, including conversations with the Exercise Officer-In-Charge of Cyber Shield as well as a cyber exercise expert working on assessment of Exercise Cyber Shield, and the research also includes information from past final reports for Cyber Shield. Issues that these large scale cyber exercises have faced over the years are brought to light, and attempts at solutions are discussed.
