Assistive Technology

on the Web

What is the relationship?

Assistive Technology

• AT definition: any item, piece of equipment, or product system, whether acquired commercially off the shelf, modified, or customized, that is used to increase, maintain, or improve functional capabilities of a child with a disability*

• There are general and computer related ATs:

* Alliance for Technology Access, Computer resources for people with disabilities, Hunter House, Alameda 2004

On one side we have

Computer-related ATs

• They can be Hardware and Software

• They can, basically:

★ facilitate/enhance accessibility of standard input/output devices

★ create new interaction channels

Software ATs

• Screen magnifiers

• On-screen keyboards

• Screen readers for blind people

• Text composition aids (e.g. with text prediction)

• Vocal recognition systems

• ...

Web ApplicationsOn the other side there are

and many more...

and their advantages...

• they are browser based, server-side and client-side applications which make the web “richer”

• they contribute in making the person free from the machine, in at least two senses:

★ any computer with a web browser and a broadband connection can easily become my virtual office

★ the machine I use doesn’t really matter, it can be a 24’’ Apple iMac as well as an XO-Laptop

Yes, something already exists...

Textic’s Talklets

WebAnywhere

And there are also portable applications, like the PortableApps suite and NVDA

Then, what is Farfalla?

• a browser-in-the-browser system

• an extensible application, which acts as a layer between an ordinary browser and a “unordinary” user

• thus, an application useful for people with different disabilities, but also for people with no disabilities at all (e.g., using non standard devices)

How does it work?

Current features

• 5 keys browsing and writing

• text prediction

• onscreen keyboard

• text-to-speech synthesis

What are the research objectives?

• To create a crossplatform framework to make new web-based assistive technology available to all users

• To study the effects of this approach on young users - the so called “Digital Natives” - with particular focus onintegration at school
