Adaptive, Multimodal Human-Computer Interfaces for the Visually Impaired
Due to the growing popularity of the Internet and other information technology systems, there is a critical need for all citizens to be empowered to access information electronically. The objective of this research is to develop the methodology and tools necessary to implement adaptive, multimodal human-computer interfaces that are personalized for individual users representing a full spectrum of visual capabilities. The specific modes to be considered for display and control interactions are: (1) speech, vocalizations, and other aural information, (2) vision, including text, images, video and computer graphics for iconic displays, and (3) haptics, including tactile information.

On-Screen Deconvolution to Facilitate Computer Access for Users With Visual Impairments
Co-worker(s): Armando B. Barreto (PI), Malek Adjouadi
This project explores the possibility of having the computer itself bridge the gap that exists between computer technology (all the benefits that it can provide) and a significant number of individuals suffering from severe eye conditions, such as Keratoconus, Pellucid Marginal Degeneration, Terrien's Marginal Degeneration, and related refraction disorders that distort the images perceived by the eye in asymmetrical and irregular ways. Traditional mechanisms of vision correction, such as glasses or contact lenses, are not addressed by these "higher-order aberrations". This project proposes the use of Point-Spread-Function (PSF), to pre-compensate (by deconvolution) the images shown on a computer screen, so they are perceived undistorted by the individual whose PSF is considered.

Analyzing Universal Design Resource Needs for Practitioners in Industry and Government
This project is for a series of studies of stakeholders in industry and government who are involved in the process of creating and purchasing universally designed products. In this project, the practical use of print and web resources by stakeholders will be studied by means of field observations and laboratory experiments. The motivation for the studies stems from the continued lack of universally designed products available on the market, despite recent US legislation that was intended to boost developments in this area.

Co-contraction of extraocular muscles in pure version-vergence circumstances (devoid of accommodative vergence).
Electromyographic recruitment of ocular muscle as an effect of muscle slack (in addition to the well-known role in causations).

European Network of Excellence ENACTIVE
The main aim is to improve the interaction between user and computer, especially including hands for performance as well as perception. One Work Package is devoted to Special users and users.
Project start date: 01/2004
Project end date: 12/2007

MICOLE (Multimodal collaboration environment for inclusion of visually impaired children)
The MICOLE project is aimed at developing a system that supports collaboration, data exploration, communication and creativity of visually impaired and sighted children. In addition to the immediate value as a tool the system will have societal implications through improved inclusion of the visually disabled in education, work, and society in general. While the main activity is the construction of the system, several other supporting activities are needed; the most important being empirical research of collaborative and cross-modal haptic interfaces for blind and visually impaired children. Empirical experiments are carried out to find out how to use different senses to partially replace missing visual capabilities, especially in tasks that are central in the system being constructed.

Finger Tracking System
Co-worker(s): Björn Breidegard, Sven Strömqvist
Using eye-tracking technology, a automatic finger tracking system makes it possible to reconstruct blind people’s tactile reading in real time and to automatically analyze finger movements during Braille text reading and tactile picture recognition. Research results indicate how Braille readers can increase awareness of their own reading styles. This opens up for future Braille education to become more evidence-based and, at the same time, for a new research field: contrastive studies of language in its auditory, visual and tactile manifestations.
