The University of Athens Speech and Accessibility Laboratory has created an online directory where persons with disabilities can download free Windows software to make their PC more accessible. The lab has installed and tested over 160 applications, including free voice to text and speech software..
The disability software is divided into 5 technology categories:
- Motor disability
- Low vision
- Speech Disability
Each entry includes the developer name, version number, a description, system requirements, information on installation, settings, and downloads (including internal and external links), and a screenshot.
The site provides three ways to search for applications: by assistive technology category, type of disability, or by alphabetical listing. Following are profiles of nine free programs.

The magnifier works with Windows XP and Vista.
Applications for Mobility Impaired StudentsAngle Mouse
The Angle Mouse improves the efficiency and ease of Windows mouse pointing for people with impaired motor skills. The application runs in the background. The Angle Mouse is "target-agnostic:" it continually adjusts the control-display (C-D) gain based on mouse movement. When the mouse moves straight, it moves quickly. But when the mouse corrects abruptly, often near targets, it slows down, making targets easier to reach. The Angle Mouse works on Windows XP and Vista machines.Tazti Speech Recognition Software
