Conceptual and Perceptual Foundations of Data Sonification
In order to create effective sonifications (representing scientific data using non-speech audio), we need to know (1) the best sound parameter to use to represent a given data dimension; (2) whether an increase or decrease in the sound parameter best represents an increase in the data dimension (this is called "polarity"); (3) how much change in the sound is required to represent a give data change ("scaling"). In addition, we need to study (4) differences among individuals, such as working memory, musical training, and listening experience, to determine their impact on understanding auditory displays. Also, we need to know (5) how best to train listeners to use auditory displays and (6) the additional "context" sounds that auditory graphs need to be effective (the equivalent of axes, tick marks, and labels in a visual graph). We are investigating all of these issues, with both sighted and visually impaired participants.
We are taking what we have learned, and using it to build software for creating auditory (and visual) graphs from a data set (The Sonification Sandbox), and software for displaying exact values using sound (The Audio Abacus). See more at sonify.psych.gatech.edu/research/index.html
Eventually, sonification software should be able to take into account the nature of both the data and display dimensions, as well as who is listening to the resulting sonification. Effective auditory graphs will have great utility for both sighted and blind scientists, students and educators.

SWAN: System for Wearable Audio Navigation
We have developed a wearable system to assist people who cannot see in navigating from place to place. An auditory display directs the user using non-intrusive, non-speech audio beacons, and in addition can augment the listener's environment to label objects, surface transitions, locations, and personal annotations.

Impact of Low Vision and Rehabilitation on Elder Literacy
Co-worker: Rickilyn M. Mancil
The purpose of this two year project is to evaluate the literacy skills of visually impaired elderly veterans and non-veterans (primarily women) who have age-related visual impairment, and to understand the relationship of literacy skills and abilities to outcomes in visual rehabilitation. Low vision among elderly persons is expected to increase as the most prevalent visual impairments are age-related; macular degeneration, severe glaucoma, diabetic retinopathy and cataract. This project will add to the knowledge about the reading and writing abilities of this population and will discover whether current rehabilitation services are restoring literacy skills for this population. This project will discover whether there is a relationship between literacy and functional independence and quality of life for this population.

Jonathan West

A Helen Hamlyn Research Associates project to create information design guidelines for the prescription blister pack. This design study created a risk management tool to be used in the design and implementation of medical packaging.

Working with pharmaceutical company GlaxoSmithKline, this project aimed to directly improve design practice within the company.

The risk management tool consists of a website which takes the user through the three scenarios of home, ward and pharmacy. For each scenario, the series of tasks involving the pack are described, with an outline of possible errors at each stage. For each error, the causes and effects are listed. Where the cause is poor design, pictorial examples of offending packs are listed, along with recommendations for design improvements. The tool also contains concept packs designed as a response to the outlined medical errors. Two of the concepts were prototyped.

The Contextual Design of ICT to Enable Elderly and Disabled People to Carry Out Daily Living Tasks
Co-workers: Ray Adams, Paul Curzon, Penny Duquenoy, Suzette Keith, Judy Wilson
Our current research focus is on design in context, investigating how everyday people actually work with and use information technology. We are interested in observing people making practical use of information resources in the context of their daily lives. We are looking at the assumptions they make, the metaphors they use and how they make sense of this activity. Our starting point for this programme has been to work with older people exploring how their life experiences and capabilities affect their use of technology. The application area we are currently considering is e-government. Local council services are increasingly being mediated online and the information concerned is of relevance to everyday life. Older people also have an increasing need for local government services as a result of changes in lifestyle.
Start and End dates of project: The project is currently (Autumn 2003) in it's pilot stage.

Development of assessment procedures for prescribing computer assistive devices
Development of an assessment protocol that includes vision, audiological and performance assessment. This protocol ascertains potential productivity with different assistive devices, and will enable a client to decide whether optical devices, screen magnifiers and/or screen readers with speech output will be necessary for computer use. If visual access is appropriate, the assessment will determine optimum magnification, lighting and other visual set-up requirements. The assessment is designed to be completed in 2 hours and does not require keyboard or computer skills.

Access to Convergent Media Project
Co-workers: National Centre for Accessible Media (NCAM); America Online (AOL)
This project addresses the problems of universal access to the growing body of programming and related services arising from the convergence of television, computer, and internet technologies. Because of the highly visual nature of these media, this project will concentrate on access solutions for blind and low-vision consumers. Blind and visually impaired users must be able to easily track available program and service options, and access solutions must anticipate how these users interact with graphic-rich user interfaces. The integration of access solutions into this new collection of media will offer significant gains to all users in homes, schools and workplaces in the near future .

VideoTact
Development of the VideoTact, a highly flexible electro-tactile sensory substitution system. The VideoTact takes visual information from a computer monitor or camera and transforms it into patterns of small electrical stimuli that can be felt on the skin. Other types of information such as audio signals, or pressure transducer signals can be transformed into patterns of electrical stimulation on the skin, and recognized by the brain - hence the term tactile sensory substitution. Further research: 1) Appropriately displaying Windows events so that they are most discriminable; 2) Determining a greater number of 'tactile color' regions in the stimulus space. The tactile colors aare used to help avoid masking effects when presenting one tactile object in the context of another. 3) Reduction in the cost and complexity of the system. Research system available for US$45,000.00 (depending on the array configuration).
