At the first meeting Steve Berger proposed a three level strategy for developing EITAAC guidelines.
The purpose for Functional level or generic Guidelines would be to act as the fundamental, performance based, underlying guidelines. These would be supplemented by more specific guidelines for the different families of products and by even more specific guidelines for particular types of products or product form factors.
Where more specific guidelines existed, they would take precedence. Where they did not exist, then the general guidelines would apply. The more specific guidelines should of course be consistent with the general guidelines but may go furthers or provide exceptions as appropriate.
This writeup is a first pass at creating function based performance guidelines.
Function Based - means that the guidelines apply to general or basic functions rather than to specific types of devices. A particular device or system might involve all or just one of the functions described.
Performance Guidelines - are guidelines that specify what should be accomplished but not how to achieve it. An ideal performance guideline
IP -1 (All) technologies used for production of information packages or packets should allow for and facilitate the creation of alternative modality formats (visual, audible, tactile and text) if the basic format is not modality independent (e.g., text). [Except where it would present an undue burden]
SS-1 (All) technologies and formats providing a storage function should support the linked storage of alternate modality formats for any information stored (unless it is modality independent) [except where it would present an undue burden]
SS-2 (All) technologies providing a serving function should support the serving of information either a) in flex-modal form (where user can choose the modality for presentation after it arrives) or b) in a select-modal form where the user can specify which modality (visual, audible, text) that they want the information served/sent in. [Except where it would present an undue burden]
[An example of flex-modal would be a closed captioned, closed descriptive movie with a full script text track]
[An example of the select-modal would be a server that would send a graphic, a text or an audible version of the information on request.]
TTD-1 (All) technologies and formats providing a transport function should be capable of transporting flex-modal information packages without distorting or removing any components of the package. [Except where it would present an undue burden]
TTD-2 (All) technologies and formats providing a transport function should be capable of supporting user directed routing of specific information types to translators so that they automatically show up in alternate formats or in a combination package (containing both original format and translated format of the information) [except where it would present an undue burden]
Note: A format is considered to be in accessible form if it can be readily translated into accessible form by a free , readily available (to the user) utility.
(Note: P1a and P1b are alternate wordings for the same concept)
------------------
P-1a (All) technologies that present information to the user for any purpose (directly or indirectly) should be able to present the information in visual, visually enhanced, audible, audibly enhanced, and tactile form [as is possible without undue burden]
P-1b Technologies that present information to the user for any purpose (directly or indirectly) will do so in a fashion that can be perceived by a person:
[AT THE MEETING THE GROUP LIKED P-1b BETTER, SINCE IT SPECIFIED THE GOAL RATHER THAN SUGGESTING SOLUTIONS (WHICH IN FACT MAY OR MAY NOT MEET THE GOAL FOR A PARTICULAR TECHNOLOGY)
P-2 Technologies which present information in a time sequenced manner should allow user to control the pace of delivery over a very wide range (5 x normal), be able to freeze presentation at any time and allow the information to be re-presented in whole or in part. [as is possible without undue burden]
P-3 Technologies which provide a presentation function should avoid triggering seizures in users who are sensitive to presentational stimulation (for example, people with photosensitive epilepsy who can experience a seizure when confronted with flashing light in certain frequency ranges) [except where it would present an undue burden]
P-4 Technologies that provide presentation functions that cannot meet P1 through P3 for all users should provide a mechanism for wirelessly connecting an alternate display (remote console).
[except where it would present an undue burden]
P-5 Technologies that are meant to be interacted with via voice should also support TTY interaction.
---------------
Notes:
C-1 (All) Technologies that provide a control function should allow operation of controls by users:
C-2 Where C-1 cannot be met for all users, products providing controls should allow alternate control and display (remote console) devices to be used wirelessly to control the product
C-3 Technologies which have biometric identification mechanisms should support alternative, non-biometric identification mechanisms.
Technologies that allow or support interaction between people (real or artificial) in either synchronous or asynchronous form should:
I-1 support real time translation of the information streams between different sensory modalities.
I-2 Where I-1 cannot be met for all sensory modalities, provide a means for connecting alternate technologies capable of translating information into different modalities.
I-3 Technologies that are meant to be interacted with via voice should also support TTY interaction.
