Audio Enriched Links provide previews of linked web pages to users with visual impairments. Before a user follows a hyperlink, the Audio Enriched Links software presents a spoken summary of the next page including its title, its relation to the current ...

Point estimation is a relatively unexplored facet of sonification. We present a new computer application, the Audio Abacus, designed to transform numbers into tones following the analogy of an abacus. As this is an entirely novel approach to sonifying ...

Tables remain a persistent problem for visually impaired people using screen readers. Tables are complex structures that are widely used for different purposes such as spatial layout or data summarisation. The multi-dimensional nature of tables ...

A number of studies have proposed interactive applications for blind people. One line of research is the use of interactive interfaces based on sound to enhance cognition in blind children. Even though these studies have emphasized learning and ...

Using Internet Archive's Wayback Machine, a random sample of websites from 1997-2002 were retrospectively analyzed for effects that technology has on accessibility for persons with disabilities and compared to government websites. Analysis of Variance (...

This paper describes the evaluation of software, software designed to allow visually impaired users to explore the structures of chemical molecules using a speech based presentation. Molecular structures are typically presented as two dimensional ...

Biometric input devices can provide assistive technology access to people who have little or no motor control. We explore a biometric control interface based on the Galvanic Skin Response, to determine its effectiveness as a non-muscular channel of ...

We describe the UMA system, a system developed under a multi-institution collaboration for making mathematics universally accessible. The UMA system includes translators that freely inter-convert mathematical documents transcribed in formats used by ...

Movement, or mobility, is key to the accessibility, design, and usability of many hypermedia resources (websites); and key to good mobility is context and preview by probing. This is especially the case for visually impaired users when a hypertext ...

People with motor disabilities may need to adjust the configuration of their input devices, but often find this an obscure and difficult process. The Dynamic Keyboard exemplifies a potential solution. It continuously adjusts fundamental keyboard ...

The Mobile Extensible Memory Aid System (MEMOS) is an electronic memory aid system which was developed to support patients with deficits in the prospective memory after a brain injury. A special palmtop computer, the Personal Memory Assistant (PMA), ...

This paper describes the design and development of EyeDraw, a software program that will enable children with severe mobility impairments to use an eye tracker to draw pictures with their eyes so that they can have the same creative developmental ...

Speech recognition can be a powerful tool for use in human-computer interaction. Many researchers are investigating the use of speech recognition systems for dictation-based activities, resulting in dramatic improvements in recent years. However, this ...

Understanding human movement is key to improving input devices and interaction techniques. This paper presents a study of mouse movements of motion-impaired users, with an aim to gaining a better understanding of impaired movement. The cursor ...

Power wheelchair joysticks have been used to control a mouse cursor on desktop computers, but they offer no integrated text entry solution, confining users to point-and-click or point-and-dwell with on-screen keyboards. But on-screen keyboards reduce ...

This paper examines factors that affect performance of a basic menu selection task by users who are visually healthy and users with Diabetic Retinopathy (DR) in order to inform better interface design. Interface characteristics such as multimodal ...

The use of computer technology for everyday tasks has become increasingly important in today's world. Frequently, computer technology makes use of Graphical User Interfaces (GUIs), presented through monitors or LCD displays. This type of visual ...

The hierarchical structure of a program can be quite complex. As such, many Integrated Development Environments (IDEs) provide graphical representations of program structure at different levels of abstraction. Such representations are not very ...

Cognitive impairments play a large role in the lives of surviviors of mild traumatic brain injuries who are unable to return to their prior level of independence in their homes. Computational support has the potential to enable these individuals to ...

In this paper we present a new system that assists blind users in orienting themselves in indoor environments. We developed a sensor module that can be handled like a flashlight by a blind user and can be used for searching tasks within the three-...

Aphasia is an acquired communication deficit that impacts the different language modalities. PDAs have a form factor and feature set that suggest they could be effective communication tools for people with aphasia. An ethnographic study was conducted ...

The visiBabble system processes infant vocalizations in real-time. It responds to the infant's syllable-like productions with brightly colored animations and records the acoustic-phonetic analysis. The system reinforces the production of syllabic ...

We report here on our progress on a project first described at the ASSETS 2002 conference. At that time, we had developed a prototype system in which a proxy server intermediary was used to adapt Web pages to meet the needs of older adults. Since that ...

These days, accessibility-related regulations and guidelines have been accelerating the improvement of Web accessibility. One of the accelerating factors is the development and deployment of accessibility evaluation tools for authoring time and repair ...

Bookmarks are shortcuts that enable quick access of the desired Web content. They have become a standard feature in any browser and recent studies have shown that they can be very useful for non-visual Web access as well. Current bookmarking techniques ...
