Social Media Accessibility

There is a widening generation gap between adolescents growing up with social technology and adults who find it foreign and unsettling

Amanda GefterLiving online: This is your space New Scientist, September 2006

Most social media are mainly designed for people without any limitation either geographical, physical, economical or technological

it is necessary to augment social media accessibility. Social media should be available to the largest possible audience

SOMFA: Social Media For All

SOMFA focuses on: making social media available through

mass-media TV (and not only through the Web, as the Web can be a burden for a part of the society)

adapting social media contents so as to offer a multi-modal (i.e., aural and visual) content presentation

SOMFA provides a multi-modal presentation of social media contents (aural and visual) and organizes such contents in order to be

displayed on TV sets

Page 7: Somfa

SOMFA: Portability

SOMFA can be used to augment the accessibility of any social media, provided that social media contents are available in

Web syndication formats

Instead of focusing on specific social media, SOMFA relies on standards used to keep people

update, i.e. the Web syndication formats (RSS and ATOM)

Designed to be as portable as possible

SOMFA: the Coder

Coder task: avoid the creation of new ostracism forms

with regards to users with physical disabilities, who are unable to (fully) enjoy social media

transcode text-based information (title and description) of any news into vocal form

use an external text-to-speech software module to produce the vocal form

resize the downloaded pictures if the resolution goes beyond 384x288 (i.e., the portion of the TV screen that will be used to display images)

Page 13: Somfa

SOMFA: the Coder

Why an external module to do text-to-speech? To enhance portability and customization It is possible to use opensource software

(e.g., text2speech, Festival Speech Synthesis System), or commercial products (e.g., Loquendo tts)

Currently, the DSpeech freeware software is used
