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.
Download or read book Enhancing Access to Complex and Spatial Information for Blind Users of Mobile Devices written by Yu Zhong and published by . 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 ACCESSIBLE TOOLS ON TOUCHSCREEN DEVICES FOR BLIND AND VISUALLY IMPAIRED PEOPLE written by Mrim Alnfiai and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Input methods on touchscreen devices are often developed without taking into account the needs of people with no or low vision. Because of this, there has been a strong research interest in the development of techniques for touchscreen accessibility for blind people, such as integrating the screen reader in smartphone devices. However, the QWERTY keyboard and the button calculator with VoiceOver and many other proposed touchscreen keyboards are in many ways inaccessible to blind and visually impaired people because they primarily require finding key locations on a touchscreen and both hands are needed to interact with keyboard interfaces. The primary objective of this research is to create, design and evaluate button-free user interfaces that allow blind users to overcome the limitations of button-based input methods, as well as mitigate privacy and security concerns. This research presents a model of designing accessible button-free input methods on smartphone devices that assist blind and visually impaired users. This thesis outlines the progressive development and evaluation of button-free user interfaces designed to make touchscreen devices on mobile phones more accessible for blind and visually impaired individuals. The first of these, SingleTapBraille, makes inputting text faster and more accurate than with the most common standard option, QWERTY keyboard with VoiceOver. Similarly, BrailleTap makes the entry of numbers and arithmetic symbols easier than with the standard smartphone calculator. We also introduce BrailleEnter, which further improves the functionality of SingleTapBraille and BrailleTap. Lastly, we address the security concerns associated with systems that increase accessibility for visually impaired individuals, specifically the password vulnerability associated with the auditory feedback provided by the VoiceOver service. We address this with BraillePassword, which provides input feedback to the user via haptic feedback that only the user can access. Four user studies are conducted with blind and visually impaired people. Data is generated through qualitative and quantitative methods. Findings indicate that the developed Braille tools significantly enhance accessibility, and has the potential to be valuable to blind users. The proposed model allows users to overcome outstanding accessibility challenges as well as mitigate privacy and security risks they face when interacting with smartphone devices.

Download or read book Evaluation of the Accessibility of Touchscreens for Individuals who are Blind Or Have Low Vision written by Elizabeth Codick and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Touchscreen devices are well integrated into daily life and can be found in both personal and public spaces, but the inclusion of accessible features and interfaces continues to lag behind technology’s exponential advancement. This thesis aims to explore the experiences of individuals who are blind or have low vision (BLV) while interacting with non-tactile touchscreens, such as smartphones, tablets, smartwatches, coffee machines, smart home devices, kiosks, ATM machines, and more. The goal of this research is to create a set of recommended guidelines that can be used in designing and developing either personal devices or shared public technologies with accessible touchscreens. This study consists of three phases, the first being an exploration of existing research related to accessibility of non-tactile touchscreens, followed by semi-structured interviews of 20 BLV individuals to address accessibility gaps in previous work, and finally a survey in order to get a better understanding of the experiences, thoughts, and barriers for BLV individuals while interacting with touchscreen devices. Some of the common themes found include: loss of independence, lack or uncertainty of accessibility features, and the need and desire for improvements. Common approaches for interaction were: the use of high markings, asking for sighted assistance, and avoiding touchscreen devices. These findings were used to create a set of recommended guidelines which include a universal feature setup, the setup of accessibility settings, universal headphone jack position, tactile feedback, ask for help button, situational lighting, and the consideration of time."--Abstract.

Download or read book Spatial Tactile Feedback Support for Mobile Touch screen Devices written by Koji Yatani and published by . This book was released on 2011 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mobile touch-screen devices have the capability to accept flexible touch input, and can provide a larger screen than mobile devices with physical buttons. However, many of the user interfaces found in mobile touch-screen devices require visual feedback. This raises a number of user interface challenges. For instance, visually-demanding user interfaces make it difficult for the user to interact with mobile touch-screen devices without looking at the screen--a task the user sometimes wishes to do particularly in a mobile setting. In addition, user interfaces on mobile touch-screen devices are not generally accessible to visually impaired users. Basic tactile feedback (e.g., feedback produced by a single vibration source) can be used to enhance the user experience on mobile touch-screen devices. Unfortunately, this basic tactile feedback often lacks the expressiveness for generating vibration patterns that can be used to convey specific information about the application to the user. However, the availability of richer information accessible through the tactile channel would minimize the visual demand of an application. For example, if the user can perceive which button she is touching on the screen through tactile feedback, she would not need to view the screen, and can instead focus her visual attention towards the primary task ( e.g., walking).In this dissertation, I address high visual demand issues found in existing user interfaces on mobile touch-screen devices by using spatial tactile feedback. Spatial tactile feedback means tactile feedback patterns generated in different points of the user's body (the user's fingers and palm in this work). I developed tactile feedback hardware employing multiple vibration motors on the backside of a mobile touch-screen device. These multiple vibration motors can produce various spatial vibration patterns on the user's fingers and palm. I then validated the effects of spatial tactile feedback through three different applications: eyes-free interaction, a map application for visually impaired users, and collaboration support. Findings gained through the series of application-oriented investigations indicate that spatial tactile feedback is a beneficial output modality in mobile touch-screen devices, and can mitigate some visual demand issues.
