Usability in the Internet of Things (IOT) in the Smart Home is a new concept with limited current research, especially in user perception. User perception is an important aspect in the development of Smart Home Internet of Things systems, including smart home products and devices and in the design of the Smart Home experience. The aim of my thesis is to investigate user perceptions of Smart Home Internet of Things systems to understand how usable current Smart Home Internet of Things systems are from the perception of the user and how that impacts the Smart Home experience. By understanding the usability of Smart Home Internet of Things systems, we can better design Smart Home devices and products for a user-centered experience. My thesis informs the design of user-centered Smart Home Internet of Things systems and experiences.

This study includes a literature review and an empirical study. The empirical study is a usability testing survey that investigates user perceptions of Smart Home technology that make up the Internet of Things system in the Smart Home. Both closed-ended questions and open-ended questions are included in the survey for a comprehensive study. Main results showed that current smart home systems are somewhat usable. Results also showed that smart home users are satisfied with current smart home systems, believes that smart home technology adds value to their lifestyle, and will continue to use smart home technology. Main results showed that the strengths of current smart home systems design are efficiency, learnability, memorability, and enjoyability. Main results showed that there is a trend between age group and smart home user perceptions. These findings inform the design of user-centered smart home systems.

We discuss processes involved in user-centric security design, including the synthesis of goals based on security and usability tasks. We suggest the usage of implicit security and the facilitation of secureuser actions. We propose a process for evaluating usability flaws by treating them as security threats and adapting traditional HCI

We discuss processes involved in user-centric security design, including the synthesis of goals based on security and usability tasks. We suggest the usage of implicit security and the facilitation of secureuser actions. We propose a process for evaluating usability flaws by treating them as security threats and adapting traditional HCI methods. We discuss how to correct these flaws once they are discovered. Finally, we discuss the Usable Security Development Model for developing usable secure systems.

As much as SARS-CoV-2 has altered the way humans live since the beginning of 2020, this virus's deadly nature has required clinical testing to meet 2020's demands of higher throughput, higher accuracy and higher efficiency. Information technology has allowed institutions, like Arizona State University (ASU), to make strategic and operational changes to combat the SARS-CoV-2 pandemic. At ASU, information technology was one of the six facets identified in the ongoing review of the ASU Biodesign Clinical Testing Laboratory (ABCTL) among business, communications, management/training, law, and clinical analysis. The first chapter of this manuscript covers the background of clinical laboratory automation and details the automated laboratory workflow to perform ABCTL’s COVID-19 diagnostic testing. The second chapter discusses the usability and efficiency of key information technology systems of the ABCTL. The third chapter explains the role of quality control and data management within ABCTL’s use of information technology. The fourth chapter highlights the importance of data modeling and 10 best practices when responding to future public health emergencies.

Online learning has been more prevalent since the rapid increase of the technology field, this paper examines if the interactivity of an online learning website can affect learning, usability, and time spent interacting. Participants were collected from Amazon Mechanical Turk, and they were compensated $1.00 for their time. 39 participants received one of three online learning conditions on the ideal gas law with varying levels of interactivity (video, simulation, quiz). The participants took a pretest, interacted with their condition for a set time, then completed a posttest and a usability survey. An ANOVA was conducted on time, usability, and posttest transfer scores. A repeated measures ANOVA was conducted on pretest and posttest recall scores. There was no significance found for learning, usability, or time spent interacting with the online learning platform. Further studies should consider exposing participants to learning materials for longer periods of time.

Access to data is an important part of today's society. Quick, accurate information is often assessed through big data. The use of this data is integral to law enforcement and business operations. These agencies must have access to reliable background check systems to perform their jobs effectively. Not only do these systems have to be accurate, but they also must be usable. Poor usability of a system can result in user error and confusion. Additionally, when a user is not able to effectively find the information that they are looking for in a system, they are more likely to stop using it. To ensure companies are providing users with the best information possible, usability studies are often performed by companies to optimize their products. A usability survey (SUS) was distributed to those in law enforcement and/or government work to evaluate user experience. Participants with experience in LexisNexis and the National Instant Criminal System (NICS) completed a ten-question survey. Results from the survey tool were analyzed and showed that users preferred the usability of the LexisNexis database over the NICS database. Recommendations include consulting and/or hiring a UX practitioner for further investigation into usability issues in the NICS system. Long-term agency investment decisions could be determined based on employee usability feedback. Therefore, periodic usability surveys should be part of any organizational plan to ensure optimal user experience. Continued development and modifications of existing content are a fundamental part of any database search site.
