Implementace uživatelsky orientované vizualizační platformy pro proudová data / Implementation of a user-centered visualization platform for stream data

Balliu, Ilda January 2020 (has links)
With the complexity increase of enterprise solutions, the need to monitor and maintain them increases with it. SAP Concur offers various services and applications across different environments and data centers. For all these applications and the services underneath, there are different Application Performance Management (APM) tools in place for monitoring them. However, from an incident management point of view, in case of a problem it is time consuming and non-efficient to go through different tools in order to identify the issue. This thesis proposes a solution for a custom and centralized APM which gathers metrics and raw data from multiple sources and visualizes them in real-time in a unified health dashboard called Pulse. In order to fit this solution to the needs of service managers and product owners, Pulse will go through different phases of usability tests and after each phase, new requirements will be implemented and tested again until there is a final design that fits the needs of target users.

Development of an Upper Limb Robotic Device for Stroke Rehabilitation

Lu, Elaine Chen 14 December 2011 (has links)
Stroke is the major cause of permanent adult disability worldwide. Often stroke affects the motor control of the upper limb, leading to difficulties in performing activities of daily living. Many hours are spent in resource-intensive therapy to regain functionality of the upper limb. In order to decrease the burden to therapists and increase access to rehabilitation, an upper limb rehabilitation robotic device was developed. Observations from therapists and an international survey of stroke therapists were conducted to understand general requirements of an upper limb rehabilitation device. These requirements were the basis of the mechanical design portion of the prototype. The prototype was evaluated with stroke therapists in a focus group. Although more iterations of design, testing and evaluation are needed, this project is a step in developing a lower cost, portable device to increase access to upper limb stroke rehabilitation.

Privacy and Proportionality

Iachello, Giovanni 03 April 2006 (has links)
Over the past several years, the press, trade publications and academic literature have reported with increasing frequency on the social concerns caused by ubiquitous computingInformation Technology (IT) embedded in artifacts, infrastructure and environments of daily life. Designers and researchers of ubiquitous computing (ubicomp) technologies have spent considerable efforts to address these concerns, which include privacy and data protection issues, information security and personal safety. Yet, designing successful ubicomp applications is still an unreliable and expensive endeavor, in part due to imperfect understanding of how technology is appropriated, the lack of effective design tools and the challenges of prototyping these applications in realistic conditions. I introduce the concept of proportionality as a principle able to guide design of ubiquitous computing applications and specifically to attack privacy and security issues. Inspired by the principle, I propose a design process framework that assists the practitioner in making reasoned and documented design choices throughout the development process. I validate the design process framework through a quantitative design experiment vis--vis other design methods. Furthermore, I present several case studies and evaluations to demonstrate the design methods effectiveness and generality. I claim that the design method helps to identify some of the obstacles to the acceptance of ubiquitous computing applications and to translate security and privacy concerns into research questions in the design process. I further discuss some of the inquiry and validation techniques that are appropriate to answer these questions.

User-Centered Design in Agile software development for in-house enterprise tools

Farebo, Samuel January 2015 (has links)
The Agile software development model is driven by "learning by doing" and rejects Big Design Up Front (BDUF) for that reason. User-Centered Design (UCD) on the other hand requires a more holistic view to be able to create a usable user interface and in the end create a good user experience. Finding a balance between the incremental development and the need for a more comprehensive view of the user interface is therefore the key to usability in Agile software development. The objective of this master thesis was to construct a framework on how to combine UCD and Agile development in general, and specifically for the web based tool, called Alo, at the IS/IT department of Com Hem AB, Sweden. The results of this thesis was that the process of integrating User-Centered Design in Agile software development first of all needs a familiar starting point for both usability experts and developers. This can be achieved with what Desirée Sy describes as “Cycle Zero”, to let usability experts perform initial research ahead of implementation. Designing one sprint ahead should later converge to a more synchronized process where requirements and sketches of the interface are put together, with the help of developers, just in time for the implementation. This does not only prevents waste in the form of documentation and miscommunication associated with hand-offs, but also makes the implementation more purposeful and fun for developers.Secondly, build prototypes early in the process to create a holistic vision of the finished product and to test concepts in usability tests early. Thirdly, create shared understanding (within the development team as well as with outside stakeholders) of user needs by involving the entire team in usability testing. Critical to the success of all the above is that all outside stakeholders understands the Agile process and respects that the team is a self-organizing unit that solves problems within a set of given boundaries, rather than a code factory that feeds on specification documents.

Utilizing user-centered design for the University of Victoria’s international connections mapping application

Macek, Ian 05 December 2012 (has links)
This thesis explores the design of a website to communicate international activities undertaken by or associated with the University of Victoria. The research was seeded by and undertaken in collaboration with the University of Victoria’s office of Vice-President Academics and Provost, and the Office of International Affairs. The thesis introduces and implements a product design process to create a mapping application for the university to display all of its international connections. The thesis advanced the study of how to incorporate users into the design process of an online map. User-centered design is an established practice of studying users and collecting their feedback during all stages of design. This process has begun to be used for online mapping. A challenge with online mapping is that potential users can be an unwieldy community. In this case study the users could come from anywhere within the UVic community, but also the public. With such a large and diverse group, incorporating all the potential users into the design process is not possible. A challenge therefore is to capture feedback from a meaningful representative sample of potential users. This research describes a process of user-centered design in which a sample of users were surveyed at the beginning of the process to determine their requirements and preferences for a mapping application, and then interviewed to test the usability of the product. The thesis concludes with recommendations for design and layout of an online mapping application, including identification where further study or decisions are required. / Graduate

Espinoza, Jorge, Loarte, Pamela, Espinoza, Carlos, Paz, Freddy, Arenas, Juan January 2018 (has links)
El texto completo de este trabajo no está disponible en el Repositorio Académico UPC por restricciones de la casa editorial donde ha sido publicado. / Pursuit of innovation projects with the absent of a methodology to follow hampers the development of the software product as its complexity grows since the freedom of its own advancement is confused with the lack of order on it. Traditional and agile methodologies do not adapt to this kind of projects therefore, in this paper we aim to design a model that incorporates characteristics of both of them to get a solution of a need found in society. In this study, we focus on the construction of a mobile application that answer to the lack of a system that integrates pharmaceutical products from different establishment through the appliance of usability concept with the UCD (User centered design) approach. In this case we only detail about four of the seven stages proposed in the model developed with its techniques, tools and activities conducted. Results obtained show that the model proposed achieve the expectative and its use is not limited to just mobile applications but to any kind of software project. / Revisión por pares

Design of a Construction Safety Training System using Contextual Design Methodology

Baldev, Darshan H. 21 November 2006 (has links)
In the U.S., the majority of construction companies are small companies with 10 or fewer employees (BLS, 2004). The fatality rate in the construction industry is high, indicating a need for implementing safety training to a greater extent. This research addresses two main goals: to make recommendations and design a safety training system for small construction companies, and to use Contextual Design to design the training system. Contextual Design was developed by Holtzblatt (Beyer and Holtzblatt, 1998) in an effort to address the challenge of designing new systems. Ethnographic in nature, the Contextual Design methodology requires field data collection, requirements analysis, model building, visioning and story boarding, and prototyping. A sample of 12 participants consisting of 7 tradespersons, 3 forepersons, and 2 owners/ managers, was selected for data collection. The data was analyzed based on the Contextual Design approach and a training system prototype was designed. The results of this study are recommendations for safety in small construction companies, a low fidelity paper prototype of the training system, and recommendations on future use of Contextual Design for developing training systems. / Master of Science

Systems Design: Academic Advising System Implementation, A Case Study of User Centered System Design at the University of Central Florida

Jones, Tracy 01 January 2015 (has links)
This dissertation presents a case study in user-centered design completed at the University of Central Florida. Leadership in the College of Graduate Studies at UCF realized the need for an advisement tool to assist advisors in the academic colleges to track the success of their students. After an advisement product was selected, the user-centered design approach started to be implemented. End-users were shown the basic functionality and known benefits of the product. Then they were asked how they could make it standardized across programs. The users selected the order in which information and degree requirements should display. The users asked for additional information to be shown on the new advising report called the Graduate Plan of Study (GPS). This information would assist them in advising students and certifying that the students' had met requirements to earn their degree. With the help of the end-users, a prototype was developed and delivered to computer services. End users assisted with the testing of current and additional functionality. After attending focus groups, the end-users had a better understanding of the need for testing. They assisted in providing ideas for training and a deployment plan to the university. The use of the user-centered design approach helped to keep our end-users engaged in the project. They were the central cause of the successful implementation of a new advisement module for graduate students at UCF.
