Objectives and Strategy of TC 100
Two major objectives of TC 100 standardization are:
to enrich human life with entertainment provided by audio, video and multimedia in home and networked environment; and
to contribute to society by pursuing energy efficiency and by addressing the options for accessibility in the use of audio, video and multimedia equipment.

Accessibility
TC 100 recognizes accessibility as one of AAL topics
In 2007, TC 100/AGS recognized the need of investigation for accessibility standardization and established a Stage 0 project to produce a Technical Report (published in 2010 )IEC TR 62678: Audio, video and multimedia systems and equipment activities and considerations related to accessibility and usability
- Downloadable free of charge from IEC Web store
TC 100 is developing a “text-to-speech” standardIEC 62731: Text-to-Speech Functionality for Television - General

AAL Challenge
Develop systems, devices and interfaces that older people can use comfortably, intuitively and independently in their homes
Not to feel being watched
Monitor people's health, keep their homes secure and help them stay fit and connected with family and friends
Overcome barriers to the acceptance and usability of AAL systems through innovative user-centric design and accessibility needs of elderly and disabled people

Barriers to Accessible Solutions
IEC TC100 AAL Study Session2012-05-15
Design mainstream ICT products / services so that the visual presentation can be adjusted by the users (e.g. displays with adjustable font size, contrast, use of colours)
Provide second audio channel / trackto narrate the visual component ofTV broadcasts / videos
Ensure that audio outputs are adjustable in sound volume & quality
Provide text captions enabling deaf peopleto follow the audio component of
TV broadcasts / videos
Design ICT products/services sothat they are compatible withassistive technologies for blindusers such as text-to-speechsoftware
Design mobile phones to minimise interferences with hearing aids
Provide alternative to speech input in interactive voice systems
Provide text telephones & operator relayservices enabling text phone users to communicate with
voice phone users
Design public telephones, ticket machines, information kiosks,
cash dispensers so that they are accessible to wheel chair drivers
Design key pats, touch screensand other interfaces to cater for people
with dexterity problems (e.g. less sensitive, better spaced, larger buttons)
Visual impairments Hearing impairments

Physical &mobility impairments
Provide speech, audio and other outputmodes as alternative to visual displays & status indicators on ICT products
Provide audio & other output modes as alternative (e.g. vibrating) to audio signals
Provide text telephones & operator relayservices enabling text phone users to communicate with voice phone users
Design ICT products/services so thatthey are compatible with assistive
technologies for people with dexterity impairments (e.g. alternative input devices)
Cognitive impairments
Design online services and otherICT-based products so that they are understandable and usable bypeople with cognitive impartment (e.g. simple/consistent menu structure,consistent use of icons , easy language)
Design online services and other ICT-basedproducts to accommodate age related changes in information processing capabilities(e.g. lower reaction speed, less fine motorskills, reduced memory capacity)
Online content too difficult tounderstand (e.g. complex
language)
Interface / menu too complex
to useCannot talk to voice-based services & systems such as
call centres & interactive response services
Public terminals
unreachable in wheelchair
Interfaces requiring too fine manipulation

Proposed Way Forward for TC100
Define use case for standardisation
Example: Barriers to Smart TV take up
Use cases are the basis for further development of standards in the following areas
– Terminology
– Technical requirements
– Interoperability
– Standard Gap Analysis

Use Case: Smart TV (1) (Guido Gybels, EBU) Barrier to current Smart TV uptake is the home networking and UI usability
For example, even though about 25% of UK households now have a Smart TV with an iPlayer in it compared to about 11% of households who have iPlayers on a tablet, the consumption of BBC content through the tablet version is 4 times as high as on a Smart TV
This indicated that many people don't actually connect their smart TVs to a network.
There is scope for both use case and guidelines work to define the requirements and functionality for easy home networking - setting up and using a device. The complexity of IP home network setup is quite a barrier for many people.
Because quite a lot of AAL activities focus on medical/well-being and monitoring, there must be scope for the role of Smart TVs and definition of a common framework and an application environment to deliver e.g. medical services via a return path of a connected TV and other consumer equipment.

Use Case: Smart TV (2) (Guido Gybels, EBU) The external connectivity of Smart TVs offers a great opportunity to deliver
external accessibility solutions by means of applications running on tablets and the like and allowing for instance a blind user to operate their TV through a TTS based smartphone or tablet app, but also elderly people with diminished sight and perhaps dexterity problems to control their TV with a more accesible remote control app on a tablet.
You could also deliver additional content. Manufacturers already have some remote apps but these aren't designed for accessibility and because there is no agreed standard for control in this way that external access technologies could use, there is an interoperability problem for such applications as well as a problem of interfaces/functionality.
For instance, it is no good to have an external control API that, say, an application for blind people could use to offer an external speaking solution if the API has no function to turn on/off the AD.
