why oats
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

FLOSSIE Conference

assistive technology
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

FLOSSIE Conference

floss what do at users want
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

FLOSSIE Conference

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

FLOSSIE Conference

floss strengths
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!

FLOSSIE Conference

oats floss what s in it for developers
OATS FLOSS What’s 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

FLOSSIE Conference

oats examples
Oats Examples
  • Dasher
  • AutoHotkey
  • PowerTalk
  • Special Access to Windows

FLOSSIE Conference

why did we open source saw
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

FLOSSIE Conference

automation of the at user iinterface the big idea
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

FLOSSIE Conference

slide17

Dynamic Selection Set - A User’s 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

summary
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
