This book was released on 2015 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: For people with visual impairments, accessing visual information in mobile settings can be difficult and sometimes frustrating. They often need to depend on assistance from family or strangers, and thus limit their exposure to unfamiliar settings so they can avoid inaccessible information. While there are many mobile applications dedicated to providing improved access of visual information for visually impaired users, there is still a long way to go towards providing an ideal user experience. This thesis focuses on enhancing visual information retrieval and interpretation for blind people with two sets of technologies. The first is computer vision, which provides us numerous algorithms to process images and videos in order to efficiently extract visual information of blind users' surrounding environment, and sometimes fulfill their needs promptly or even in real time. The second is crowdsourcing, also known as human computation. Crowdsourcing has been shown to be an effective means to solve problems that automated approaches cannot yet handle. With carefully designed infrastructure, leveraging large groups of online workers can yield accurate and fast responses to blind users' various visual information requests. This dissertation surveyed existing algorithms and applications of both computer vision and crowdsourcing and identified challenges visually impaired users face from questions they submitted to our services, then carefully designed frameworks to fit components from both categories together into several assistive mobile applications for blind people.
Download or read book Making Spatial Information Accessible on Touchscreens for Users who are Blind and Visually Impaired written by William Grussenmeyer and published by . This book was released on 2017 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Touchscreens have become a de facto standard of input for mobile devices as they most optimally use the limited input and output space that is imposed by their form factor. In recent years, people who are blind and visually impaired have been increasing their usage of smartphones and touchscreens. Although basic access is available, there are still many accessibility issues left to deal with in order to bring full inclusion to this population. One of the important challenges lies in accessing and creating of spatial information on touchscreens. The work presented here provides three new techniques, using three different modalities, for accessing spatial information on touchscreens. The first system makes geometry and diagram creation accessible on a touchscreen through the use of text-to-speech and gestural input. This first study is informed by a qualitative study of how people who are blind and visually impaired currently access and create graphs and diagrams. The second system makes directions through maps accessible using multiple vibration sensors without any sound or visual output. The third system investigates the use of binaural sound on a touchscreen to make various types of applications accessible such as physics simulations, astronomy, and video games.

Available in PDF, EPUB and Kindle. Book excerpt: Seminar paper from the year 2012 in the subject Business economics - Business Management, Corporate Governance, grade: A, The University of Liverpool, language: English, abstract: Abstract A great number of smart phones still are inadequately interactive with visually impaired and blind users and thesteps to providing access that actually exist does not give or sustain some of the tasks efficiently. This literature review presents some of the issues and gives different yet effective solutions and guidelines to improve the Smartphone's interface with visually impaired and blind users. CHAPTER 1: INTRODUCTION Nowadays, mobile devices allow the disabled people with many different opportunities to act independently in the world. However, these powerful and competent devices may have large number of interactivity challenges, especially for the people who are blind or visually impaired. Research and different studies proves that a blind or visually impaired person has better capability to rely on other senses most importantly the touch and audio sensors. This literature review would be dealing with the analysis and studies of different interfaces for the blind and visually impaired patients, keeping in view the important points that favour the user in every way. Using the haptic concept, to elaborate the letters for the blind user while writing a text message or calling someone and an audio interface to direct and communicate between the phone and user. There are some problems that hinder blind users to interact with the Smartphonewhich includes screen touch, interface, text entry, navigation, individual differences and some other problems. There are no efforts that have been made to discover the control of touch or smart phones in non-visual mobile interface. In this lecture review, I am going to present some works that have been done recently about interacting challenges with Smartphone devices and blind people.

Download or read book Visual Impairments written by National Research Council and published by National Academies Press. This book was released on 2002-08-17 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: When children and adults apply for disability benefits and claim that a visual impairment has limited their ability to function, the U.S. Social Security Administration (SSA) is required to determine their eligibility. To ensure that these determinations are made fairly and consistently, SSA has developed criteria for eligibility and a process for assessing each claimant against the criteria. Visual Impairments: Determining Eligibility for Social Security Benefits examines SSA's methods of determining disability for people with visual impairments, recommends changes that could be made now to improve the process and the outcomes, and identifies research needed to develop improved methods for the future. The report assesses tests of visual function, including visual acuity and visual fields whether visual impairments could be measured directly through visual task performance or other means of assessing disability. These other means include job analysis databases, which include information on the importance of vision to job tasks or skills, and measures of health-related quality of life, which take a person-centered approach to assessing visual function testing of infants and children, which differs in important ways from standard adult tests.

Available in PDF, EPUB and Kindle. Book excerpt: The Routledge Handbook of Visual Impairment examines current debates as well as cross-examining traditionally held beliefs around visual impairment. It provides a bridge between medical practice and social and cultural research drawing on authentic investigations. It is the intention of this Handbook to provide an opportunity to engage with academic researchers who wish to ensure a coherent and rigorous approach to research construction and reflection on visual impairment that is in collaboration with, but sometimes is beyond, the medical realm. This Handbook is divided into ten thematic areas in order to represent the wide range of debates and concepts within visual impairment. The ten themes include: cerebral visual impairment; education; sport and physical exercise; assistive technology; understanding the cultural aesthetics; socio-emotional and sexual aspects of visual impairment; orientation, mobility, habitation, and rehabilitation; recent advances in "eye" research and sensory substitution devices; ageing and adulthood. The 27 chapters that explore the social and cultural aspects of visual impairment can be taken and used in a variety of different ways in order to promote research and generate debate among practitioners and scholars who wish to use this resource to inform their practice in supporting and developing positive outcomes for all.

Download or read book Universal Usability written by Jonathan Lazar and published by John Wiley & Sons. This book was released on 2007-06-05 with total page 645 pages. Available in PDF, EPUB and Kindle. Book excerpt: Universal Usability is the concept of designing computer interfaces that are easy for all users to utilize. It is a concept which many decry as elusive, impossible, or impractical, but this book, which addresses usability issues for a number of diverse user groups, proves that there is no problem in interface design that cannot be solved, or at least improved upon. Individuals with cognitive, motor, and perceptual impairments, as well as older, younger, and economically disadvantaged users, face a variety of complex challenges when interacting with computers. However, with user involvement, good design practice, and thorough testing, computer interfaces can be successfully developed for any user population. This book, featuring key chapters by Human-Computer Interaction luminaries such as Jonathan Lazar, Ron Baecker, Allison Druin, Ben Shneiderman, Brad Myers and Jenny Preece, examines innovative and groundbreaking research and practice, and provides a practical overview of a number of successful projects which have addressed a need for these specific user populations. Chapters in this book address topics including age diversity, economic diversity, language diversity, visual impairment, and spinal cord injuries. Several of these trailblazing projects in the book are amongst the first to examine usability issues for users with Down Syndrome, users with Amnesia, users with Autism Spectrum Disorders, and users with Alzheimer's Disease, and coverage extends to projects where multiple categories of needs are addressed. These chapters represent real-world projects, being carried out on different continents. The authors of the chapters also represent diversity—interface researchers and software developers in university, industrial, and government settings. In the practical spirit of the book, chapter authors provide guidelines and suggestions for those attempting similar projects, as well as implications for different stakeholders such as policymakers, researchers, and designers. Ideal for students of HCI and User Interface Design, and essential reading for usability practitioners, this fascinating collection of real-world projects demonstrates that computer interfaces can truly be designed to meet the needs of any category of user.
