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.

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

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.

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

Konceptstudie för nästa version Brand- och räddningsinstruktion / Concept study for the next version Fire and Rescue Instruction

Jakobsson, Julia, Larsson, Elin January 2016 (has links)
För att brandmännen på flygplatser ska känna sig trygga när olyckan är framme är det viktigt att de får den information som krävs för att veta hur de ska agera när en flygfarkost kraschar. Utöver att vara ett stöd vid skarpa lägen ska Brand- och räddningsinstruktionen, BRI, vara ett läromedel i brandmännens utbildning och ett komplement under resten av deras yrkesliv. Dagens BRI uppfattas av användarna som en tråkig hemsida som inte är anpassad för dem, därför handlar detta examensarbete om hur BRI bör utformas för att vara användbar, samt bidra till lärande och en god användarupplevelse. Detta arbete har varit en iterativ användarcentrerad designprocess. Arbetet började med en kontextuell undersökning hos användaren för att fastställa deras behov. Utifrån dessa behov resulterade arbetet i ett förslag på ett grafiskt användargränssnitt som följer Saabs grafiska profil och som genom tester visar sig uppfylla användarnas centrala behov. Det visualiserades med en interaktiv prototyp. Genom att strukturera visualiseringarna med tillhörande text, se till att ingen information är dold och tillämpa en konsekvent navigeringsstruktur påverkas användarupplevelsen positivt. Denna studie har identifierat vikten av samspelet mellan information och visualisering för att främja användbarhet och inlärning. / When accidents happen it’s important that the airport's fire fighters feel safe with the knowledge that they have. This is why it’s important that they receive the information that is needed so that they know how to act when an aircraft crashes. In addition to being an aid during critical situations the Fire and Rescue Instruction, FRI, is a digital data bank, which is used to educate new fire fighters, and also to keep fully trained fire fighters up to date. Users perceive the FRI as a boring website which isn't designed for them. Which is why this master thesis will investigate how the FRI should be designed to improve the user experience and increase the learning effect. The process, which has been implemented during this thesis, is an iterative user-centered design process. The work began with a contextual inquiry to determine the users' needs. Their needs were then used to develop a user interface concept that followed Saab's graphic profile. The users’ then evaluated the concept to make sure that it met the users' key requirements. The concept was visualized with an interactive prototype. A positive user experience can be accomplished by structuring the visualizations with its corresponding text, you should also ensure that no information is concealed and apply a consistent navigation structure. This study has identified the importance of the interaction between information and visualizations to promote the learning effect and usability.

USABILITY IS NOT <em>JUST</em> USABILITY: DISCOVERING THE STRATEGIES USED BY NON-EXPERTS IN MAKING USABILITY PREDICTIONS

Sublette, Michelle A. 01 January 2017 (has links)
Much of the research on metacognition in human factors has focused on prescriptive, normative strategy training. That is, many researchers have concentrated their efforts on finding ways to improve system users’ prediction, planning, monitoring and evaluation strategies for tasks. However little research has focused on the strategies and heuristics users employ on their own to make usability predictions. Understanding usability prediction methods is critical because users’ predictions inform their expectations about whether they will make errors using a product, how much effort they will need to expend to be successful in using the product, whether they can perform two tasks successfully at the same time, whether the costs of learning to use a device are worth the benefits of using it, which tools will assist in accomplishing goals and which tools will make performing the same task more difficult. The following study aims to identify the specific strategies people use to make usability predictions about product designs. From these strategies a set of guidelines, for designers who wish to ensure users’ expectations meet post hoc usability assessments, were proposed. The study was completed in two phases. During the first phase of this study, prediction strategies were elicited by 1) asking participants to make routine product usability judgments, from which implicit strategies can be inferred, and by 2) using explicit free-response methods. Judgments were analyzed using multi-dimensional scaling (MDS) methods to establish the number of dimensions that are implicitly used to predict usability. Subject matter experts (SMEs) coded free-response strategies using coding schemes developed in a pilot study. SMEs will also matched user strategies to formal, professional usability standards. The outcome of Phase 1 was usability taxonomy for classifying usability strategies that includes both expert and user language. The procedure was repeated with three different product design classes to determine how strategies differ as a function of the to-be-judged product. During the second phase of the study, a new group of participants rated specific usability attributes of designs to validate the strategies collected from users’ free-responses in Phase 1. Attributes were selected based on the strategies discovered in Phase 1. These usability attribute ratings helped to inform interpretations of the dimensions of the MDS model generated in Phase 1 and provided input into defining the usability attributes that influenced usability predictions. Results of this study reveal that the type design class participants evaluated had a significant effect on the type of strategy participants used to make their a priori usability assessments (UAs). Participants reported using “complexity” or “organization” most often to predict the usability of cookbooks. Participants reported using “mental simulation” or “typicality/familiarity” most often for predicting the usability of drinking glasses. Participants reported using “complexity,” “organization,” and to a lesser extent “typicality/familiarity,” and “mental simulation” as strategies for predicting the usability of cooktops. MDS methods were used to uncover the underlying dimension of the UA space. For drinking glasses, the “fanciness” and “holdability” were associated with UAs. For cooktops, “the number of controls” and whether participants believed “it was easy to understand how each burner was controlled” were associated with making UAs. And for cookbooks, “the length of the instructions” and “poor contrast of the text with the background” were associated with UAs. Overall, there is evidence that at least some participants in Phase 2 used terminology that was consistent with the terminology people used to describe the designs during Phase 1 and that these were congruent with the uncovered strategies.
