Title: Open Source Assistive Technology Software


1
Open Source Assistive Technology Software
  • OATS
  • David Colven, Steve Lee Simon Judge

2
OATS
  • Assistive Technology
  • Accessibility
  • Advice and tools for mainstream
  • AT
  • Specialist cooperative development
  • The OATS Project
  • FLOSS software and the OATS project
  • Why OATS?
  • What does the OATS project deliver?

3
The Consortium
4
The ACE Centre
5
Why OATS?
  • An AT focus for all FLOSS development
  • Individual projects and shared
  • Interested parties contributing together
  • Many skills solving user requirements
  • Focussed, flexible and custom solutions
  • More users with transparent access
  • Transport AT to new horizons

6
Assistive Technology
  • AT software market is growing
  • However it is specialised
  • Small Market
  • Innovation limited
  • Box fitting not enough tools
  • Lots of interested individuals across sectors

7
FLOSS What do AT users want?
  • Good design and Innovation
  • Simple installation
  • Transparency
  • Reliability
  • Individual solutions to sometimes complex needs
    (even with universal design)
  • Low Cost
  • All software not just AT
  • Ask for what they want and get involved

8
Benefits
  • Open Source offers an alternative model for
    developing AT software
  • Well suited to encourage
  • Strong collaboration with users
  • Innovation
  • Customisation

9
FLOSS Strengths
  • Many projects like OpenOffice and Firefox now
    meet users needs with excellent features and
    support
  • Ideal for innovation and customising to
    individual needs
  • Community and user participation
  • Rapid development and prototyping
  • Free!

10
OATS FLOSS Whats in it for developers
  • Community and User participation
  • Infectious enthusiasm
  • Innovate and share innovations.
  • Rapid development and prototyping
  • Common library of tools and components
  • No wheel re-inventing!
  • Easily available and usable by more users
  • Their work is useful and is used!

11
Aims
  • Software!
  • Home grown OATS and existing OATS
  • Resources
  • Standards
  • Usability
  • Installers
  • Software structure
  • Data transfer
  • Resources

12
Outcomes
  • Pilot project now complete
  • Developed, fully operational site
  • Prepared means for a community
  • The Future
  • Oats to continue under day-to-day management
  • Further development of content, tools etc.
  • Thriving OS community come and join in!

13
Website
  • All Open Source AT software in ONE place
  • Links to free or low cost software
  • Easy to use searching and browsing for software
  • Links between developers and users (fora)
  • Technology transfer from research
  • Full range of development tools in Forge
  • Trac etc.

14
Oats Examples
  • Dasher
  • AutoHotkey
  • PowerTalk
  • Special Access to Windows

15
Why did we Open Source SAW?
  • Limited development resources
  • Keep the software free
  • Widen the pool of expertise
  • Open the program to new ideas
  • As an exemplar of AT development

16
Automation of the AT User IinterfaceThe big idea
  • Potential for enhanced (semi-) automated
    accessibility for switch and pointer users as
    part of a new interface design process.
  • Dynamically discover UI structure
  • Extract property information
  • Receiveevent notifications when UI changes
  • Be able to Query an element for its behaviour
  • Click a button, scroll a list, moves a window,
    etc.
  • Inject keystrokes and mouse input where
    appropriate

17
Dynamic Selection Set - A Users Tool
The wizard also constructs the appropriate script
from the available information from the browser
Links and texts extracted automatically and
constructed into a selection set
Information taken from UIAutomation is used to
put data into items
SAW works out the number of items needed and
constructs a grid of items
18
Summary
  • Provides a new model for software development in
    the AT field
  • Encourages innovation
  • Allows users to be heard
  • Is a single place to go for AT software and
    resources
