However, blind people cannot visually skim for an area of interest. Instead, they use a combination of contextual information, knowledge of the spatial layout of their environment, and interactive scanning to find and attend to specific items. In this paper, we define and compare three cursor-based interactions to help blind people attend to items in a complex visual scene: window cursor (move their phone to scan), finger cursor (point their finger to read), and touch cursor (drag their finger on the touchscreen to explore). We conducted a user study with 12 participants to evaluate the three techniques on four tasks, and found that: window cursor worked well for locating objects on large surfaces, finger cursor worked well for accessing control panels, and touch cursor worked well for helping users understand spatial layouts. A combination of multiple techniques will likely be best for supporting a variety of everyday tasks for blind users.","PeriodicalId":110197,"journal":{"name":"Proceedings of the 20th International ACM SIGACCESS Conference on Computers and Accessibility","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124091669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite their benefits, these systems can pose privacy threats to users whose data is collected. This issue is amplified by the ambiguity on how user performance data, which might reveal sensitive health data, is used by these applications and whether similar to medical data it is protected from unauthorized sharing with third-parties. In interviews with older adults who experience pointing difficulties, we found that participants felt a lack of agency over their collected pointing data and desired clear communication mechanisms to keep them informed about the privacy characteristics of adaptive assistive systems. Based on this input, we present an icon set, that can be used in online application stores or with the licensing agreements of adaptive systems, to visually communicate privacy characteristics to users.","PeriodicalId":110197,"journal":{"name":"Proceedings of the 20th International ACM SIGACCESS Conference on Computers and Accessibility","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132451414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Increasing tactile feedback and tangible interaction on touchscreens can improve their accessibility. However, prior solutions have either required hardware customization or provided limited functionality with static overlays. Prior investigation of tactile solutions for large touchscreens also may not address the challenges on mobile devices. We therefore present Interactiles, a low cost, portable, and unpowered system that enhances tactile interaction on Android touchscreen phones. Interactiles consists of 3D-printed hardware interfaces and software that maps interaction with that hardware to manipulation of a mobile app. The system is compatible with the built-in screen reader without requiring modification of existing mobile apps. We describe the design and implementation of Interactiles, and we evaluate its improvement in task performance and the user experience it enables with people who are blind or have low vision.","PeriodicalId":110197,"journal":{"name":"Proceedings of the 20th International ACM SIGACCESS Conference on Computers and Accessibility","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122449645","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We conducted a mixed-methods user study with 16 older adults (55+) to understand the impact of this unique design approach, comparing it with the smart phone's official printed instruction manual.

Interdependence emphasizes collaborative access and people with disabilities' important and often understated contribution in these efforts. We lay the foundation of this frame with literature from the academic discipline of Disability Studies and popular media contributed by contemporary disability justice activists. Then, drawing on cases from our own work, we show how the interdependence frame (1) synthesizes findings from a growing body of research in the Assistive Technology field and (2) helps us orient to additional technology design opportunities. We position interdependence as one possible orientation to, not a prescription for, research and design practice--one that opens new design possibilities and affirms our commitment to equal access for people with disabilities.","PeriodicalId":110197,"journal":{"name":"Proceedings of the 20th International ACM SIGACCESS Conference on Computers and Accessibility","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130346204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The World Health Organization estimates that the number of people with vision impairment could triple in the next thirty years due to population growth and aging. If a graphic is not described, explained in the text, or missing alt tags and other metadata (as is often the case in popular media), the intended message is lost or not adequately conveyed. In this work, we describe a multimodal deep learning approach that supports the communication of the intended message. The multimodal model uses both the pixel data and text data in a single neural network to classify the information graphic into an intention category that has previously been validated as useful for people who are blind or who are visually impaired. Furthermore, we collect a new dataset of information graphics and present qualitative and quantitative results that show our multimodal model exceeds the performance of any one modality alone, and even surpasses the capabilities of the average human annotator.","PeriodicalId":110197,"journal":{"name":"Proceedings of the 20th International ACM SIGACCESS Conference on Computers and Accessibility","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126264928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, to the best of our knowledge, the accessibility of applications developed with this framework has not been systematically investigated. In this contribution we report our experience in the development of MathMelodies 2, an application that supports BVI children to study mathematics.

In particular, document formats designed for printing, such as PDF, structure math content for visual access only. While accessibility features exist to present PDF content non-visually, formulae support is limited to providing replacement text that can be read by a screen reader or displayed on a braille bar. However, the operation of inserting replacement text is left to document authors, who rarely provide such content. Furthermore, at best, description of the formulae are provided. Thus, conveying detailed understanding of complex formulae is nearly impossible. In this contribution we report our ongoing research on Axessibility, a LaTeX package framework that automates the process of making mathematical formulae accessible by providing the formulae LaTeX code as PDF replacement text. Axessibility is coupled with external scripts to automate its integration in existing documents, expand user shorthand macros to standard LaTeX representation, and custom screen reader dictionaries that improve formulae reading on screen readers.","PeriodicalId":110197,"journal":{"name":"Proceedings of the 20th International ACM SIGACCESS Conference on Computers and Accessibility","volume":"1019 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116458221","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
