Item Restricted DESIGNING A CLINICAL TRIALS FRAMEWORK FOR WEARABLE TECHNOLOGIES AT SEHA VIRTUAL HOSPITAL IN SAUDI ARABIA(UCL, 2024) Madkhali, Marwan; Expert, PaulThe purpose of this research is to design a clinical trials framework for wearable technologies at Seha Virtual Hospital (SVH) in Saudi Arabia. The framework aims to evaluate the usability, effectiveness, and impact of wearable technologies on patient outcomes in a virtual care setting, aligning with the national strategy for digital health transformation. The research also seeks to establish benchmarks and generate high-quality evidence on the efficacy of these technologies for digital health in Saudi Arabia. The SVH, as a pioneering digital health centre, recognises the potential of wearable technologies to revolutionise healthcare by enabling remote monitoring and real-time data collection. The proposed framework will facilitate the integration of these technologies into clinical trials, contributing to evidence-based practices and improved patient care. The research methodology involved a systematic literature review to identify key themes and challenges in integrating wearable technologies into clinical trials. The review adhered to the PRISMA guidelines and included studies published between 2014 and 2024 that examined the use of wearable technologies in clinical trials for virtual healthcare delivery. Thematic analysis was employed to identify key themes and challenges. The findings highlighted the importance of usability and positive user experience, seamless data integration and high data quality, patient-centric design to promote adherence, the value of real-world evidence and feasibility studies, addressing regulatory and ethical considerations, and ensuring successful technology integration. The research also identified key benchmarks from existing clinical trials in different countries, including usability and patient-centred design, real-world data integration, methodological rigour and validation, ethical and regulatory compliance, personalised treatment plans and data accuracy, and hybrid models and flexibility. Results the comprehensive clinical trials framework was proposed. The framework incorporates needs assessment, technical performance evaluation, usability testing, feasibility assessment, and outcome measurement. It also emphasises ethical considerations, regulatory compliance, and data security. The implementation of this framework at SVH will enable the effective evaluation of wearable technologies, leading to improved patient monitoring, enhanced virtual care delivery, and ultimately, better patient outcomes. Keywords: clinical trials, wearable technologies, virtual healthcare, usability, and framework.10 0Item Restricted Understanding and Improving the Usability, Security, and Privacy of Smart Locks from the Perspective of the End User(University of North Carolina at Charlotte, 2024) Hazazi, Hussein; Shehab, MohamedOver the past two decades, the Internet of Things (IoT) has seen a significant expansion in both the sophistication and variety of its applications. These applications span several domains, including enhancing and automating services in healthcare, advancing smart manufacturing processes, and elevating home living standards through smart home technologies. These technologies empower individuals with greater control over their home appliances. Smart locks are smart home devices that were introduced as replacements for traditional locks. Smart locks, designed to go beyond the basic functionality of traditional locks by offering additional features, have seen a surge in market growth and competitiveness. According to the Statista Research Department, it is projected that the global market for smart locks will surpass four billion dollars by 2027. A number of studies have examined end users' concerns, needs, and expectations regarding smart homes in general. However, little research has been conducted to examine these aspects of the smart lock in particular. To address this gap, we conducted a series of user studies that aim to elucidate how smart locks are integrated and interact within smart home environments, focusing on user interactions both with the locks themselves and when they are part of broader automation scenarios. This dissertation contributes to a deeper understanding of smart lock technology from a user-centric viewpoint. It offers insights into user motivations, concerns, and preferences regarding smart lock usage and automation. It also highlights the importance of balancing convenience and security, the pivotal role of trust, and the complexities of integrating smart locks into broader smart home systems.34 0Item Restricted Exploring Augmented Reality App Usability: A Socially Practised Affordance Perspective.(Saudi Digital Library, 2022) Almashyakhi, Arwa; Harrington, Tomas; McKenna, BradAugmented Reality (AR) apps have the potential to transform the way in which users experience products and services. However, AR adoption rates have not yet reached the expectations of developers and the service sector. Users' expectations and experiences of AR apps can influence the adoption of AR technology. This thesis explores AR user behaviour; specifically, by focusing on the usability of AR and the underlying motives that drive users to adopt or reject AR technology. To achieve this aim, qualitative methods and multiple sources of data (858 online reviews, 62 users’ reflections, multiple apps) have been used to inform a better understanding of AR app use. Affordance theory was applied using the ‘walkthrough technique’ to identify AR affordances arising from the application of AR technology. Ten AR app affordances and five user goals were identified by investigating the performance and usage aspects of various applications. Then, social practice theory (SPT) elements (meanings, materials, competency) were applied to understand the three major characteristics of usability (interactivity, compatibility, credibility) associated with current AR apps that may prevent potential users from actualising their affordances. This study contributes to knowledge by introducing a new theory of “socially practised affordances” (SPA) which allows AR app users to actualise an app’s affordances when there is a coherence between SPT elements. Moreover, it sheds new light on how AR apps, users, and social practices are interconnected by explaining connections between materials e.g., AR apps, expected and developed meanings, user and system competencies and how these elements might drive AR apps’ users’ behaviour. This study concludes by discussing theoretical and practical implications that can give future direction to AR developers through the development of a SPA framework for AR applications.35 0
