Applying the User-Centered Design approach for Prototyping the Interfaces of an Intelligent Emergency Management System

In today’s disaster management context, decision-making and information management is a crucial aspect, given the complexity of the tasks the decision-maker has, as well as the sheer influx of information coming in at any given time. As such there is a need to develop a system that can aid both the decision makers in the command post but can also collect the information gathered by the responders on the field. This system should also aid the decision maker by providing counselling according a set of rules, giving the system an intelligent aspect. Thusly THEMIS is born, an intelligent system to support decision making in crisis scenarios. As any given system must have an interface, the usability and user experience are a concern, but given the nature of crisis scenarios, this aspect of user interfaces becomes much more critical. It is in this context that this dissertation’s goal becomes clear: design and test the interface prototype of an emergency management intelligent system, following the User-Centered Design framework. With this goal in mind, the steps of the framework were followed, by beginning to understand the user, the context of use, resulting in understanding the user’s needs. From here, the system requirements emerged, and paper prototyping began. After validation with experts and possible users, the interfaces were prototyped digitally for both the desktop and mobile system applications. This was followed by usability tests, using the Cognitive Walkthrough method, the System Usability Score and the User Experience Questionnaire. In order to complement the testing phase, eye tracking data was gathered during the desktop version’s usability tests, which gave further insight about user behaviour. As such, it was concluded that prototypes scored highly both for usability and user experience, and there was an overall improvement on the various versions of both the desktop and mobile apps. The tests with eye tracking also allowed to identify a few issues that otherwise couldn’t be detected, namely key items the users were missing on the interfaces

HMD versus PDA: A comparative study of the user out-of-box experience

The out-of-box experience (OOBE) has been identified as a significant factor contributing to user perception and acceptance of products and technologies. Whilst there has been considerable emphasis placed on formalising methodological procedures for evaluating the OOBE and on the creation of positive user experiences through appropriate interfaces and applications, relatively little work has been undertaken examining how the OOBE is impacted when the experience itself covers a range of (possibly interconnected) devices. In this paper we report the results of an empirical study which examined the OOBE when a Personal Digital Assistant (PDA) and Head Mounted Device (HMD) were configured and then connected for inter-operability purposes. Our findings show that type of device has a considerable impact on the OOBE, with the ask of interconnecting devices having a detrimental effect on the OOBE. The OOBE, however, is in main unaffected by user type and gender

From backend to Dashmobile: expanding the horizons of the drone engineering ecosystem

The Drone Engineering Ecosystem (DEE) project is a groundbreaking initiative that aims to simplify access to the world of drones and promote their responsible use, particularly in the educational domain. Traditional methods of drone control and interaction have been complex and fragmented. The DEE project seeks to overcome these challenges by integrating various technologies, including Python, Tkinter, FastAPI, MongoDB, Flutter, and Dart, to create a cohesive and user-friendly ecosystem. The project began with a comprehensive analysis of the existing drone ecosystem, identifying its limitations and areas for improvement. This was followed by the formulation of clear objectives and a detailed work plan, visualized through a Gantt chart. The development process encompassed the creation of a robust backend, significant enhancements to the existing dashboard, and the development of a mobile application using Flutter. One of the main challenges was the integration of new technologies like Flutter and Dart, which were learned specifically for this project. Rigorous testing and user experience evaluation were integral to ensuring the system's functionality and usability. The project's success not only achieved most of the set goals but also opened new avenues for future exploration and development in the drone technology field. My passion for programming and the application of my Telecommunications Engineering bachelor's degree were key drivers in the project's success. The project represents a significant contribution to the field, providing a platform for learning and promoting the responsible use of drones. It also reflects my commitment to challenging myself and applying my academic knowledge to real-world problems.Objectius de Desenvolupament Sostenible::4 - Educació de Qualita

V-Sphere Rubik's Bookcase Interface for Exploring Content in Virtual Reality Marketplace

In this work, we developed a new interface concept for content exploring in immersing Virtual Reality environments. In our shopping interface, we represent products as true 3D shapes with global illumination effects. This representation can provide more realistic and consistent Virtual Reality experience. Our shopping interface is really a giant spherical Rubik’s cube that consists of closed loops of book-shelves or cabinets. Users, who are located inside of this spherical Rubik interface will feel like they are in front of a spherical bookcase that consists of an infinite number of rows and columns. They can view the products by simply sliding rows horizontally and by sliding columns vertically. Further more, we discovered additional scenarios where users can grab the products by distance and examine their suitability by placing them into real environment. This new 3D interface concept can help to develop more realistic 3D interactive shopping framework in the future

The walkthrough method : an approach to the study of apps

Software applications (apps) are now prevalent in the digital media environment. They are the site of significant sociocultural and economic transformations across many domains, from health and relationships to entertainment and everyday finance. As relatively closed technical systems, apps pose new methodological challenges for sociocultural digital media research. This paper describes a method, grounded in a combination of science and technology studies with cultural studies, through which researchers can perform a critical analysis of a given app. The method involves establishing an app’s environment of expected use by identifying and describing its vision, operating model, and modes of governance. It then deploys a walkthrough technique to systematically and forensically step through the various stages of app registration and entry, everyday use, and discontinuation of use. The walkthrough method establishes a foundational corpus of data upon which can be built a more detailed analysis of an app’s intended purpose, embedded cultural meanings, and implied ideal users and uses. The walkthrough also serves as a foundation for further user-centred research that can identify how users resist these arrangements and appropriate app technology for their own purposes
