Description: Tactile graphics is a way for blind students to access figures and diagrams in science and mathematics textbooks. It is not satisfactory for natural images like photographs. We will introduce techniques to automatically transform figures in text books into a tactile form. A major issue is the text found in figures because it has to be identified and translated to Braille. The techniques for doing this involve image processing, machine learning, and computational geometry.

Despite reading disabilities affecting 7-15% of the population, research in access technology for reading disabilities has been limited. This talk will give an overview of reading disabilities, the few technologies that have been developed, and their limitations. The factors that have influenced and limited the research and development of these technologies will be discussed.

For any access technology to truly be helpful and beneficial, the technology itself must be adopted into regular use. However, a third to one half of all assistive technologies are abandoned after purchase. Abandonment is a waste of funds, time, research, and opportunities. This talk will discuss the issues that lead to abandonment and approaches that work towards promoting access technology adoption.

Description: This talk will present the use of the human voice as a means for controlling computer interfaces, going beyond the traditional speech recognition approach. Traditional use of speech as computer input has been restricted to dictation or command-and-control-based discrete input. I will present our work in attempting to harness the non-speech vocal parameters of human voice to enable more fluid, continuous control of computer interfaces.

Description: Long-term care of the elderly is labor intensive: care giving relies overwhelmingly on the "high touch" presence of caregivers. The cost of high touch is unsustainable given current demographic trends worldwide. Without dramatic breakthroughs in the cost of care, over half of all elders are expected to be without adequate care within a generation.
In this talk, I will describe a series of project showing how to use technology to scale the practice of care. I will describe changes both in technology and the process of connecting technology to peoples' needs. Using examples from projects under way, I will describe how technology can help in three main ways: helping elders function independently via cognitive orthotics, reducing burden on caregivers via remote monitoring and notification, and improving interactions with clinicians via clinically valid behavioral metrics. Technology is only a piece of the puzzle. I will explain why clinicians, service providers, state workers and technologists need to coordinate towards this goal. Using some recent developments as examples, I will discuss what form the coordination may take, and what the opportunities are.

Description: Despite more than 20 years of research in computer access, user interfaces still pose accessibility challenges for people with motor and visual impairments. The approach of augmenting or adapting users to standard software through specialized assistive technologies has numerous drawbacks, including the cost, complexity, configuration, and maintenance of specialized devices. As a result, less than 60% of people who indicate a need for a specialized assistive technologies actually try one, and abandonment rates are high. This talk will cover projects that approach accessibility differently. Rather than adapting people to computers using specialized devices, we will see how to adapt software to people using everyday devices like mice, trackballs, styli, and microphones, lowering the aforementioned barriers to access. In this lecture, I will show how my recent research has developed into a theme I call "ability-based design," and how we can improve accessibility using it.

As mobile devices become more capable and more complex, they
present new accessibility barriers for people with disabilities, as
well as for people without disabilities who are using devices in
distracting or disabling environments, such as while walking down the
street or riding the bus. At the same time, new advances in mobile
technology are enabling devices to sense and adapt to the user based
on their location, activity and ability. In this talk I'll describe
our recent work to increase the accessibility of mobile devices for
all users, and discuss new techniques for increasing mobile device
