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

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 Crawler
Crawler task Find and download Web contents specified
in the feed list The list of feeds represents the interests of
the user Download possible multimedia contents that
are linked in the downloaded feeds

SOMFA: the Miner Miner task:
Parse all the feeds downloaded by the crawler Extract information contained in the feeds Extract information of where to locate
multimedia contents (e.g., pictures, audio, or video) and pass them to the crawler module for actual downloading

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)

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
